Taking Care of Orchids the Easy Way

By Carrie E. Bernstein


Let's face it; orchids are amongst the most beautiful of all tropical flowers, but they have certain needs which need to be met in order to grow them successfully. You also need to bear in mind that when it comes to orchids, the window for error is considerably small, and as such, you need to familiarize yourself with certain facts.

Lighting

The vast majority of tropical orchids can be grown successfully indoors providing they receive some filtered sunlight during the day. Likewise, they can also be grown in a greenhouse if artificial lighting is used.

In most cases, if you're growing orchids in your home it is best to place the plants close to a window so that they can take full advantage of the natural light, bearing in mind that exposure to direct sunlight can in fact damage the plants.


If you have a window that receives plenty of filtered sunlight then you have an ideal location for growing your orchids. Additional light can be provided if necessary by using special grow lights.

Of course certain species of orchid, such as Phalaenopsis for example, do have special lighting requirements, and tend to do well when provided with indirect bright light during the winter months and shade during the summer.

Temperatures

Phalaenopsis and Paphiopedilum orchids are two species which require controlled temperatures at night, and the temperature should be maintained between 60 and 65 degrees Fahrenheit, irrespective of season. Other species such as Cattleyas for example, prefer nighttime temperatures of between 55 and 60 degrees, while Vandas on the other hand enjoy temperatures between 50 and 58 degrees.

Ventilation and Humidity

Orchids for the most part require specific humidity levels ranging from 45 to 65%. Fortunately, it is possible to maintain airborne moisture simply by using pebble trays. Just fill a small pan with some smallish rocks and then fill the pan with water so that the rocks are just covered. Your plants can then be placed on top of the rocks but you need to ensure that the roots are above the water level.

Periodic misting is also advisable, especially on very warm days in order to provide your plants with some additional humidity. Ideally, you should always try to mist either first thing in the morning or else it should be done around noon. This is so that you minimize the risk of fungi and bacteria attacking your plants.

Ventilation is also extremely important, and as such, you should provide a little bit of space between each of your plants. Additionally, if you cannot leave a window or two open during the day, then you should consider using a small fan instead.

Feeding, Watering, and Drainage Requirements

Providing you can give your orchids a suitable growing environment you shouldn't encounter many problems at all. One such a requirement is that you provide enough drainage, so of course you should never attempt to keep your orchids in pots that are closed underneath.

Contrary to what you may believe, orchids don't require much water at all. In fact you should only water your plants when they are completely dry.

Interestingly enough, most species, such as Cattleyas for example, have a pseudo-bulb structure which helps them to store water just as is the case with cacti.

Phalaenopsis and Vandas on the other hand do not have these bulbs and should therefore be given water once you determine that they are moderately dry.

* All orchids require some extra water during the growing phase.
* The water used for watering your plants should be at room temperature.
* When you water your orchids you need to continue supplying water until you see water draining from below the pot. Also, you should not be tempted to feed your orchids each time you water them.
* Orchids which are in the active growing stage can be fed occasionally with a food that has a 20-20-20 label.
* Those which are finished with the growth stage can be fed a 10-30-20 food due to the fact that they don't require as much nitrogen.
* The vast majority of commercial orchid to foods are highly concentrated, and as such, you'll only require about a quarter of a teaspoon per gallon of water.

Outdoor Orchids

Plants which are grown indoors can be moved outdoors usually during the month of May, at which time you'll need to provide them with a certain amount of shade. Providing you exercise a sufficient amount of caution in terms of where you decide to place your plants, they can be left out for most of the summer.

Some orchids such as Vandas for example really enjoy sunlight, and apart from the hottest time of day, these orchids will do just fine in full sun. In fact, even the flowers will be able to tolerate a full day of sun, while Phalaenopsis and Paphiopedilum on the other hand will require full shade.

Orchid Care

By Nigel Howell

A lot of people find their love for orchids after they have received one as a present. With that love however comes a responsibility of orchid care. Information about caring for orchids can be overloading but here are some basics that you need to consider.

Watering - A common mistake is watering too much. You need to ensure that you wait until your orchids are sufficiently dry (but not completely dry) before you water thoroughly. Check beneath the surface of your growing medium to see if it is dry. There is no hard and fast rule of when to water but try to do it no more than weekly unless you are sure it is dry.
Temperature - Most orchids originate from tropical regions so like temperatures in the 60s, 70s and 80s. Whilst there are orchids that can grow in the cold, cold temperatures usually damage the plant and you will see a yellowing of the leaves and they will fall off.


Feeding Orchids - A common question in the orchid care is how to feed orchids. There are homemade remedies and fertilizers that you can buy from the shop. The best time to use orchid feed is in spring. Don't use orchid feed in the winter months.

Re-potting Orchids - You will need to report when your orchid grows out of the pot and when you need to change the growing medium. Re-pot before new growth appears on your orchid.
Orchid Light Requirements - You need to get enough light to your orchids but the orchid shouldn't be left in direct sunlight all day. Getting the light right is arguably the most important factor in orchid care. If they don't get enough then they won't bloom properly. Think about where you place you orchid in relation to the light, south facing windows generally get more light.

Orchid Humidity Levels - Most people don't even consider these but they are easier to control than most people think. Use a spray bottle to mist to ensure there is enough moisture in the air.

Orchid Care Problems - Other problems that you might come across when caring for orchids include insect and disease problems. Clean you orchid regularly to ensure they remain healthy.

Caring for orchids is a hugely rewarding experience. Once you start with your first orchid it is likely you will catch the orchid bug! Don't be daunted, after a little experience, orchid care will become easy for you.

Care of Orchids - The Container Gardening Guide to Growing Exotic Orchids

By Eric Samms

Orchids add a touch of class to your container gardening collection, but many container gardeners avoid them like nobody's business. These beautiful plants have a reputation for being demanding and difficult specimens to manage.

However I'm hear to tell you that you are missing out on some amazing plants if you haven't explored orchids. Although it is best to make a note of the specific requirements of each variety, Just keeping a few tips in mind will help you avoid the pain and heartache.

1. Start with Easy Care Varieties and Look for good quality plants

There are many popular types of orchid, including cymbidium hybrids, cattleyas, dendrobiums, oncidiums and vandas. For the beginners out there, I recommend staring with an easy care variety such as cymbidium hybrids.


This variety is readily available, easy to grow and easy on the pocket. Phalaenopsis (which are popularly known as the moth orchids) and Cypripediums (also known as slipper orchids) are also an easy variety to manage. are also commonly recommended for most beginners. The draw back of growing some orchids is that the they can grow a lot of foliage. As the flowers may only emerge for one - two months you could spend most of the year with a lot of unsightly leaves. If you prefer a more compact, but still manageable variety, consider the Miltonias.

First, when choosing an individual plant don't worry if you see some roots out of the mix. Orchids are epiphtes i.e. therefore the roots like being exposed to the air, and should look healthy and solid, not broken-up and spindly. It is best to choose plants with firm and shiny leaves and already in flower. Buying orchids in flower allows you to see the color and assess the plant for it's ability to produce healthy flowers.

2. Orchids need sunlight

however I recommend avoiding direct sunlight. If you have any dark areas at home, consider some artificial lighting for a few hours in the day.

Light is the key factor to successfully raise and bloom orchids. It is often possible to determine much light an orchid needs by looking over it's the leaves. The ideal leaf color is a light grass green. If your orchid is receiving too much light, the leaves become very yellow; therefore you will need to move the plant to more shade. If the leaves turn a very deep and dark green the orchid may not be receiving enough light. .
3. Orchids need plenty of humidity.

Place the containers in a gravel tray containing some water (making sure that the water does not reach the top of the pebbles) , or mist at regular intervals. If you keep in mind that humidity is affected by temperature and light, it is better to mist during the day time. Adding humidity late in the day or in the evening may contribute to excessive condensation which could result in leaf and root rot.

4. Orchids are sensitive to draughts and cold temperatures.

Keep them away from draughty windows especially at night.

Cymbidium hybrids like cool rooms with very good light and a minimum temperature of 11?C is ideal between October and May. Phalaenopsis / Doritaenopsis hybrids & Paphiopedilum hybrids
Keep this orchid in a centrally heated room with a minimum temperature of 15?C. Vuylstekeara, Odontocidium, Miltonia, Odontoglossum, Oerstedella, Masdevallia & Epidendrum hybrids
A cool, well-lit position out of direct sunlight with a minimum temperature of 11?C is suitable all year round.

5. Orchids require regular feeding in the summer.

orchids are very adaptable plants, grabbing nutrients from whatever happens to be nearby - leaves, droppings, or minerals in rainwater. Give your orchids a little help by feeding it the right fertilizers. Look for products that contain nitrogen (N), phosphorus (P), and potassium (K), along with trace elements such as iron.

6. Repot your orchid only when the roots have filled the container, and make sure to use specialist potting mixture from your garden centre.

Different potting mixtures are required for each orchid genus, depending on whether it is land growing or epiphytic (tree growing and obtaining nutrients from the air). Fir bark, coconut husk, tree fern fibers, sphagnum moss usually make up the potting media. Re-potting at regular intervals helps re-fresh the potting media.

Orchids may be potted in a variety of containers, however the container material may influence the watering frequency. Because clay pots dry out faster than other pots, plants in clay pots will need more frequent watering. Do make sure that your pots have good drainage, as orchids and their roots are not designed to stand in water.

7. Over watering is not a good idea.

It is best to water when the compost is almost dry. Most orchids are epiphytes, they are air plants and won't grow in soil. The roots need to dry slightly between watering.

I recommend watering your orchids just once a week in the winter and twice a week in the summer. Of course climatic conditions and potting mixture will affect the amount of moisture retained, so it is always a good idea to test your moisture levels if you are unsure whether to water. Poke your finger in to one inch, and if it feels damp (but not soggy) you don't need to water. Make sure that do not let the potting mixture completely dry either,

As most orchids in the wild grow on trees or other plants, they get moisture from the air. An Allow water run to or be sprayed over the roots and surrounding moss, but do not let them stand in water. Over watering your orchids usually results in mushy, brown, dead roots.

Remember less is more!

I don't recommend watering with tap water, as this is chemically treated. Go for rainwater and preferably at room temperature. The shock of cold water is a contributing factor towards early orchid death,

8. Room temperate in most homes will be acceptable for growing orchids, anywhere between 55F at night and 80F during the day is best.

Another thing to remember is that in their native environment nearly all plants are exposed to constant breezes. Orchids are no exceptions. Moving air will help them and cut down on disease problems. A small fan will quickly pay for itself by giving you better growing conditions.

In the wild, gentle continual breezes along the leafy canopy of the rain forest are vital for the survival of orchids and other air plants. Air movement acts as preventive medicine for orchids. It helps evaporate stagnant water, trapped during watering, where fungi and bacteria breed. Without ventilation or fresh circulating air, orchids eventually die from rot, lack of a continual carbon dioxide source, or infection. Ventilation also helps orchids tolerate intense light without getting burnt leaves.

You can easily improve air movement in your home so orchids grow happily. During the summer, when temperatures are high, open windows to allow fresh air to come inside. And when wintertime comes, you can use an ordinary oscillating fan to mimic the gentle breezes in the leafy canopy of a tropical forest. It is important to occasionally change the direction of the airflow so the area does not dry out.

A Guide to Orchid Pest Control

By D Swain

It is common for orchid growers to have problems with various pests. Calling an exterminator for orchid pest control is often unnecessary as well as expensive. There are things that you can do to deal with these pests yourself. This article will discuss common methods of orchid pest control.



Spider Mites

The first part of orchid pest control focuses on spider mites. They can be some of the most troublesome pests for orchid growers. Most plants usually have mites, and they feed on plant sap by the thousands. You should keep the humidity high to control spider mites, especially during the winter. You can also try using predatory mites or spraying the plants with water on a regular basis.

Aphids

Aphids are also a focus of orchid pest control. These tiny insects can damage the plants by sucking juices. They are also capable of carrying a virus from one plant to the next. Since aphids develop resistance to insecticides quickly, the best method of orchid pest control for these insects is spraying the plants with water on a regular basis. Lady beetles and small, predatory wasps also help control the aphid population.


Mealybugs

Another part of orchid pest control deals with mealybugs. These insects also suck plant juices, but do not spread diseases. If they are not kept under control, they will become a big problem. You should keep any new plants away from your other plants for a few weeks to make sure they are not infected with mealybugs. Since mealybugs have a waxy covering, water-based insecticides do not perform well. The best way to deal with an infestation is to remove each one with a dental pick.

Scales

One of the next areas of orchid pest control is scales. Scales are small insects related to aphids. They feed on plant juices and are usually found on stems and leaves. You should regularly check your plants for aphids. If you spot some, you simply need to scrape them off using a sponge or tissue.

These are the best methods of orchid pest control. If you regularly check and clean your plants, they will be fine. There is no need for you to call an expensive exterminator for orchid pest control.

How to Care For Orchids in Different Environments

By Carl Harrison


Many people love orchids because of their vast varieties and how delicate they are. Whether you are a novice gardener or an old pro, this flower is a big time favorite. Yet, many new gardeners worry that they don't have what it takes to make these flowers bloom. By following some simple care tips, the garden you want to create will be beautiful.

If you live in a temperate region, you're able to take your potted orchids outside during the summertime. The majority of cymbidiums along with Coelogynes, Dendrobiums and Encyclias thrive well in summertime conditions. However, if you have smaller orchid plants, it's best to leave them inside.

If you want your garden to look good and don't want to transfer plants from inside to outside, you can choose some terrestrial orchids that do well outdoors. Which ones?

- Cypripedium calceolus
- Cypripedium reginae
- Dactylorhiza

These are typically found in the areas of Europe and North America.



Caring For Orchids In A Temperate Environment

Summertime and Moisture

You should be mindful that summers in the temperate zone are generally hot and dry. It's important that any plants you have outside are watered regularly and done during the evening hours. Be sure to follow this rule so that new growth on your plant will be protected from the scorching summer sun. Keep roots cool so that the moisture on your roots stays on for longer periods of time during the summertime.

When you know rain is in your forecast, consider placing a tent over your orchids so that the medium does not get too soaked from the rain. However, you need to remove the tents once the rain is over. If not, the heat can get trapped under the tent, damaging your plants.

Mounting Plants In Lieu of Potted Plants

If you'd rather mount your orchids instead of potting them, there are several species that do well on bark. They include:

- Encyclia polybulbon
- Trichopilia tortilis
- Dendrobium miyakei
- Brassia verrucossa
- Laelia anceps
- Oncidium flexuosum

What you use to mount your orchids is going to depend on the species you plan to grow. For instance, you can use a piece of wood or bark. Keep in mind that you can add a hook to either one, which gives you the choice to hang your orchid plants down the road.

There are other things you will need when you want to mount your orchids. These include:

- Fishing line (or plastic coated wire)
- Gloves (you must wear these so that you do not get a fungal infection when you handle sphagnum moss)
- Sphagnum moss

Loosely put the moss around the plants roots as well as on the medium you are going to use. The moss cushions the roots and keeps it from getting damaged from whatever you use (string or wire) to hold the plant in its place.

You'll need to tie the moss you have to the bark but be gentle about it. You certainly don't want the plant to be loose so secure it. You want the root to get into the bark. If you have extra moss, trim it up to make it look better.

You can use the above procedure when you mount the plant to tree trunks or tree branches. You'll need to make sure you have enough water because they don't retain moisture like potted plants will.

Growing Orchids All Year in the Tropical Environment

In most tropical regions, it's not uncommon to find orchids growing all year. Some of them can be seen on tree trunks and/or branches. Types of orchids that survive in the shade and can handle the temperatures change of the day.

Are Orchids in Danger of Going Extinct

Every year, the tropics endure hurricanes, which have winds that can pull up orchids and damage them. Should the tree that the plants are on fall the orchids will quickly die. However, orchid societies will watch for weather events and rescue the plants to ensure their survival.

Dendrobium Orchid Care

By Jeremy Sleigh

Dendrobium orchid care is no more involved than caring for any other species of orchid. They are a common choice to use as cut flowers because they have a very beautiful and distinctive color and a very string stem. Making the a little Dendrobium orchid perfect for occasions like weddings or a good romantic gift.

But enough with all the waffle, you want to learn how to take care of Dendrobium orchids right? Well, you can't fail with the following tips:

Lighting

These particular orchids love light, and it is important so that they can maintain healthy growth. Provide Bright light, to 50 percent sun. In the home, an east, west or lightly shaded south window. In a greenhouse, about 30 to 50 percent of full sun. Under lights, four 40 watt incandescent bulbs directly over plants. Plants should be naturally erect, without need of (much) stalking, and of a medium olive-green color.


Temperature

The temperature for your Dendrobium orchid care is important as well. Temperature is directly proportional to the amount of light so both should be looked at carefully. As a guide temperature below 50F and above 90F are not a good idea. Ideally there will be a difference of about 10 degrees between night and day.

Watering

Keep evenly moist while in active growth. Allow to dry between waterings after growth is mature (indicated by terminal leaf). The trick is to keep in wet, but not too wet. For adivce on how to do this visit the site mentioned at the end of this article

Humidity

Dendrobiums need 50 to 60 percent. In the home, place on trays over moistened pebbles. In greenhouse, use a humidifier if conditions are too dry. Humidity trays can be purchased from gardening stores but its much better and cheaper to just make your own.

Potting

Should be done every two to three years before mix loses consistency (breaks down). Pot firmly in medium, giving aeration and ample drainage, allowing enough room for two years' growth. Dendrobiums grow best in pots small for the size of the plant. For the best Dendrobium orchid care though, don't repot unnecessarily as this will do more harm than good.

Care of Dendrobium Orchids

By Robert Roy

Dendrobiums

This month I am focusing our attention to the care of Dendrobiums. These are one of the most popular of retail orchid plants. They are a true epiphyte or air plant. There pseudopods can gather and hold water very efficiently. Generally there will be a hybrid phalaenopsis and dendrobium, commonly known as Dtps.


Potting

This needs only to be done every two to three years and it should be with a porous, free draining media. This may be a combination of wood chips, small stone and and pieces of styrofoam peanuts. This will allow the draining of water and fertilizer. Dendrobiums seem to grow best when the pot is smaller than the size of the orchid plant.


Lighting

The dendrobium orchids require about 50% sun or bright light. They will do well in an east or west window as well as a shaded south window.

They also do well under 4 - 40 watt fluorescent lights directly over the plant.

Temperature

These plants need a difference in temperature between the night and day. Preferably this difference should be about 10 - 15 degrees. The night temps they like is 60-65 with days between 80 - 90.

Air circulation is needed and is especially when the temps are above 90 degrees.

Water

Like most orchids Dendrobiums need to be kept moist while actively growing. When it is mature, as are most of orchids-plus-more.com plants they should dry between watering.

Dendrobiums thrive when the humidity is about 50 - 60%. Humidity trays are usually needed while the plant is in the home.

Fertilizer

Use a balance fertilizer like Jack's Classic 20-20-20. Use weakly, weekly. That is, use a solution which is between 1/4 to 1/2 the recommended dosage.

Growing Orchids as House Plants

Executive summary By Robert Roy

Some orchid plants have been around for centuries.

Watering
Orchid house plants and orchid plants in general will need watering periodically, usually you can water once a week. Here is a watering guide you can use: Cattleya, oncidium and dendrobium orchids like to dry out between watering. An easy way to water is to put the plant in the sink and let water flow through the plant for about 1 minute. Plhalaenopsis orchids like to almost dry out between watering.

Humidity
Light is the next most important element to growing orchid plants. As a general statement most orchid house plants do well in medium light. Most orchids do well in normal house temperature.


Learn How You Can Grow Orchids At Home

Executive summary By Lee Dobbins

Many people think that growing orchids is something that can only be done in big hothouses however, you can grow orchids at home if you pick the right type and provide it with the right environment.
  • Humidity
  • Water
  • Fertilize with a water-soluable fertilizer made specifically for orchids.
  • Sunlight. Different types of orchids need different amounts of sunlight and if you can’t provide natural sunlight you can try fluorescent grow lights. SoilYou can buy ready mixed orchid potting mixes and this is what you should use for your orchids.
  • Pests. Orchids can be prone to diseases and pests.

In Orchid Care The Flower Will Tell You About Some Diseases

Tale for orchid care the flower. The orchid flower is usually a thing of beauty. When diseases strike it can be tell - tale. Like the leaves, the flower can tell you a great deal. Let's take a look at what we will learn...

Spotting of Flowers

A sign of fungal infection or mold is pink or light brown spots on the flower. When you see either, orchid care will suggest to be careful with your other plants as the infection can spread to other plants.
Remove the orchid flowers that are affected. The remedy is to get more circulation.

Flowers With Punctures

Yes, those aphids can get at orchids, too. Also, some insects including Thrips.
Orchid care the flower suggests that the remedy is spray the orchid with malathion, but be careful and use a face mask.


Flowers With Mottled Colors

Here caring for orchids will strongly suggest a second opinion is necessary. The cause could be a color losing virus. Even if this is suspected then isolate the plant. If it is a virus then you need to destroy the plant.

Bruised Flowers

The causes of bruising are many. It could simply be from mechanical injury. If this is the case the area of damage will not increase or go on to other flowers.

But it could also be from slugs or even cockroaches. You may need to investigate and use some dust to bait them. If from cockroaches then diazinon or Sevin on the ground around the plant, on the plant and the pot as well.

Caring for orchids also shows that the bruising can be from red aphids. If so use the malathion treatment.

Rapid Wilting Of The Flower

If you see wilting of the flower, especially the dorsal or upper septal this can be caused by a sudden temperature change or pollination from an "unknown" pollinator. (I didn't think orchid flowers were that particular!!). The remedies are those that make sense, moderate the temp changes and remove the affected flowers. Not sure what to do for the unknown attacker.

Deformed Flowers

Caring for orchids is not complete without the a word about deformed orchids.

Common causes include;

low humidity or high temp when the buds were developing
mechanical or chemical injury during bud formation

the bud has acquired an unexplained deformity

the potential of a virus infection, (you see many of the flowers have the deformity). Need to isolate the plant.

Caring for orchids does involve looking at the "whole plant". In orchid care the flower is important.

Temperatures - Most mature orchids need about 15 to 20f temperatures between night and day.
Water - Never let plants dry out.
Fertilizer - Must be fertilized on a regular basis, but requires less fertilizing than most orchids. Use a good 10-10-10 balanced ratio
Potting - Should be done about every one to two years.

Oncidium - Oncidiums are from sea level to the tropics.
Temperatures - should be 55-60f at night and 80 85 during day.
Water - Generally plants with large fleshy roots needs less water. Watering should be thorough. Plants not active should be watered less. Do not leave in standing water.
Fertilizer - Apply a good 30-10-10 balanced fertilizer twice a month.
Potting - Re-pot when plant is about half mature. Keep Humidity high and new pot should be medium dry until new roots form.


Dendrobium- Are very common at retail stores. Also called an air plant. Very leafy appearance. They love the early morning sun.
Temperatures - Mature plants like 15 to 20f difference between night and day. Leaves may drop if temperatures drop below 50f.
Water - They like moist soil but can tolerate dryness when plant is matured.
Fertilizer - They like to be fertilized often especially during growing period. Use a good 10-10-10 balanced ratio.
Potting - Repot every 2-3 years, give good aeration and drainage. They tend to like small pots for their size.
Visit Houseplant Care for free indoor houseplant care tips.

The Phalaenopsis - This is a favorite among orchid care enthusiasts. Long-lasting blooms with many colors and are really inexpensive. These blooms are moth like in apperance.
Temperatures - Should be about 55-60f at night and 80 85 daytime. Seedlings need about 10 degrees higher than mature plants.
Water - Do not let plants dry out. Younger plants needs more watering and attention.
Fertilizer - Should be fertilized on a regular basis. A good 10-10-10 fertilizer or anything close ratio. Fertilize every week at one quarter to one half of recommended dilution.
Potting - Should be done every 2-3 years. Better if done during late spring.

Remember always use a good orchid care fertilizer and soil for all orchids. Typically the above orchids are what most nurseries have, but there are over 28,000 varieties.

Easy Care Of Phalaenopsis

Do you have a knack for being with moths? Most people would say, "no way". Yet, the moth orchids that I am talking about are the ones that sway nicely in the breeze and some of the newer hybrids have a nice fragrance. These moths are easy to care for, especially a beginner. These moths are found very frequently in gardens. These are the phalaenopsis orchids.

Phalaenopsis orchids are the one of the easiest orchids to care for in a home. Their blooms can last up to 3months and there are some of the most colorful hybrids. Like other orchids they require light, water, temperature, fertilizer and humidity. Seems like a lot but it really isn't

The best light is indirect light. It can be bright but not direct sunlight. If you have a west facing window sill this will do just fine. Direct sun can damage the leaves of the moth orchid.


Humidity is needed for the moth orchids. They actually grow in the wild in humid rain forests. In the warm months it would be nice to mist them every day or two. They also enjoy a bright bathroom.

Let's look at the temperatures that phals like. They are an intermediate temperature orchid. This means they like temperatures from 55 to 75 or 80 degrees. As a must, the must be a temperature gradient of 10 to 15 degrees for at least 14 days in the fall to stimulate their flower spike.

Moth orchids have no pseudopods to store water and for this reason they should not completely dry out. It is fine line to let them nearly dry out and at this point water them. You should be able to tell by seeing how light the plant is before you water it.

Another way is stick your finger tip down about an inch into the plant and it should feel almost dry. It is at this point you should water. Let the water run through the plant (in the top and out the bottom) for about 20 - 30 seconds. It is important that any orchid plant does not sit in water because it will get root rot.

Fertilize the plant twice a month with a week fertilizer solution. It is recommended to cut amount of fertilizer recommended by one half. Fertilize about every other week with a balanced fertilizer except durng the summer months of growth when you can use a high nitrogen fertilizer.

Orchid Care – Feed, Humidity & Re-potting

The world of orchids is a challenging one, but it is this challenge which captures the imagination of many growers. You have to keep an eye out for bugs when caring for your orchids but perhaps the biggest one is the one you may catch yourself, the orchid bug, you will be an enthusiast for life!

Feed

As with humans, plants can do with extra nutrients than they find naturally. If you do decide to use feed, aim for a specialist orchid feed which will contain all the necessary nutrients in the correct proportions. General fertilizers can be used as long as they are not too strong, ask somebody at the place you purchase if the fertilizer is suitable for orchids.



Humidity

Orchids like humidity. It is sometimes difficult in the summer months to maintain the required humidity as greenhouses develop a dry atmosphere. It is perhaps worth investing in a hygrometer as this device will tell you exactly what the humidity of the air is. A cheap but effect way of introducing humidity is by using a hand sprayer. You can spray your orchids a few times each day but be careful not to spray too much each time. Avoid spraying on open flowers as they may develop brown spots. A more experienced orchid grower may consider introducing fogger jets. Fogger jets are extremely effective and work by breaking the water up into fine fog.

Re-potting

Orchids may need re-potting for a number of reasons. The compost may begin lose its nutritional content, it may begin to decompose, it may have been over watered and therefore become waterlogged or may have outgrown their surroundings.

Ideally re-potting should happen around spring time but if your orchid requires re-potting, the period of the year shouldn’t prevent you from doing so. Look out for re-potting every 2 to 3 years.

When it is time to re-pot you need to decide which compost to use. There many different types of compost you can choose. Choose compost which drains easily as one of the common reasons some orchids die is because of over watering.

You need to choose a pot which is the correct size and provides plenty of drainage. You should only consider increasing the size of the pot if that was the reason for re-potting in the first place.

Once you have re-potted the plant put it in a shady place for 1 to 2 weeks. Give it about a week until its first watering session but careful not to over water.

Orchid Care - Fertilization and Pest Control

Caring for orchids requires a bit of knowledge about the pests that tend to attack them, as well as proper fertilization techniques to help them grow. The stronger your plants, the better they will be able to resist common diseases and insects, and the best way to keep orchids healthy and strong is to fertilize them.

Orchid plant care is an area that has been heavily studied, particularly as many of the tropical species grow on tree branches, anchoring themselves to a host and appearing to thrive on thin air. While the more terrestrial orchid species tend to be easier to grow, they still require special care.

Pests That Attack Orchids:

Orchids have many natural enemies and anyone attempting orchid care at home will need to be aware of these. Some of the most common pests include slugs and snails, which are usually not difficult to get rid of. Others, however, are. Mealybugs, whitefly, and mites are also enemies of orchids.

There is also an aphid called the orchid aphid which attacks these plants. Aphids exist everywhere that orchids do, and because of this, they are a great threat to the flowering plants. Orchid care includes watching for these tiny pests, which are often not much bigger than a speck. These multiply rapidly, but like most pests, can be banished if caught early on when there are only a few. For this reason, it`s just good sense to check your plants for insects on a regular basis.
For many interested in orchid care, biocontrol is the preferred method of keeping nasty insects at bay. Using friendly insects that eat the pests and don`t hurt the orchid can be a good way to go if you don`t want to risk chemical sprays. However, orchid plant care also requires proper feeding and fertilization to ensure the hardiness of the plant.

Orchid Care: Fertilization:

Most orchid care guides will tell you that the fertilization depends on the species of orchid, and this is true to an extent. While various species have their preferences, the majority do well with soluble fertilizers or plant food.

There are actually fertilizers specially formulated for growing orchids and these provide just the right balance of nutrients for the plants. If you choose to go with a more generic type of fertilizer with a 20-20-20 balance.

Orchids tend to grow in the wild where little nutrition is found. Understanding this, it is best to keep your orchid plant care efforts to a minimum. Many orchids are killed by giving them too much fertilizer or by over watering them. So, when feeding orchids, it is best to use about half the recommended dosage on the package and to use the fertilizer in place of water. Orchids only need to be fed once a month or so.

While orchids are not quite as delicate as many people assume, they do still require some special care. Making sure that you don`t over-fertilize the orchids and immediately dealing with any pests, before they get out of hand, is the best way to ensure top notch orchid plant care.

Orchid Light Requirements - Find The Right Light For Your Orchid

All plants need light to survive, the same way we need to eat food and breath. Without it any plant will die and orchids are no exception to this rule. The real issue is that different types of orchids (there are 1000's of them) require different amounts of light. Some orchids live in very warm sunny climates while others live in damp rain forests. The trick is to know what type of orchid you have and try to mimic the same orchid light requirements that they would receive in nature.

Not everyone is familiar with the type of orchid they have or its lighting requirements. The good news about this is that there are universal symptoms you can look out for that can tell you if your orchid is getting too much, or not enough light.


Too much light for your orchid may mean some of the following

  • The plants leaves may show brown and/or yellow burn patches on its leaves. The leaves of the orchid may also be rough and slightly raised.
  • Too much light for your orchid may mean the leaves feel warm to touch.
  • The orchids leaves may become red.
  • The leaves may bleach/become black/become red depending on your orchid type. Look out for all 3.

Not enough light for your orchid may mean

  • The leaves become dark green,
  • When the flowers bloom they are smaller than the previous bloom or,
  • There are hardly any blooms on the plant when it blooms,
  • The orchid begins to go limp and lacks life,

Generally you can use your own logic here, if the plant doesn't look healthy then chances are you are not providing the correct orchid light requirements.

Luckily for us, the solutions are simple. If your orchid seems to be getting too much light, leave it in a shady area for a little longer each day. If the orchid is not getting enough light, place it by the window for a little longer each day. I like to keep my orchids behind the blind, so that a little light can shine through during the day but it doesn't over do it. This does the trick just right for me.
