General Orchid Information
Flowering orchids are best kept in a bright, airy place in the home away from direct sunlight and overly warm temperatures. For maximum flower life, maintain an even moisture level. (Jan 10)
The first step in caring for your orchid is knowing whether it is a phalaenopsis, dendrobium, vanda, cattleya, oncidium, paphiopedilum or cymbidium. Most people who have just a few orchids will have a Phalaenopsis. (Jun 09)
The reason is practical: your success as a grower will be helped a lot by knowing some basic names. Locating information on your plants can depend on correctly recognizing its type. (Oct 11)
Most cultivated orchids are epiphytes (growing in trees or on rocks rather than in the ground) and sympodial (growing sideways while monopodial orchid plants grow upwards).
Pick up a plant label from one of your plants. Most likely, the name will consist of at least two words. The first word is the name of the genus (think of it as a person's last name e.g., Smith). (Sep 09)
For scientific reasons, all plants have names which distinguish their genus and species. Frequently, individual plants are given a third name.
1. Don't Overwater - put your finger in the mix, if it feels wet, it is, let the mix dry. 2. Buy Mature Plants - choose a the plant in bloom, seedlings are harder to grow.1 3. Visit Your Local Orchid Society
Orchids growing in the wild don't have the benefit of a caretaker to primp and preen them. But their only purpose is to attract a pollinator, not please us humans.
Have Flowers in Every Month of the Year
There is no right or wrong way to collect orchids, but there are some things to consider that will give you the most bang for the buck. And some guidelines for selecting plants that may keep you from wasting your money.
Growing Your Orchids - Orchid Culture Basics
The importance of water, light, temperature, fertilizer and potting for growing phalaenopsis, or Moth Orchids, the most popular orchid for the home. Click here if you are not sure of what kind of orchid you have. (Jul 09)
Today is the first day of spring and for orchid growers, that means our orchids will be commencing their annual growth cycle soon. The most important task we associate with spring is repotting our plants. (Mar 12)
Orchid roots are different from the roots on common house plants, in part because of the spongy velamen layer, and require potting mixes that allow enough air around the roots. (Oct 09)
The number one reason that orchids don't rebloom is that they're not getting enough light. Here are some quick ways to check your light levels, and the SAOS has a light meter for you to be sure! (Nov 09)
Pseudobulbs on orchids like cattleyas store energy & water and prefer a wet dry cycle. Fleshy leaved orchids like phalaenopsis only have their fleshy leaves so they prefer to be more evenly moist. (Feb 10)
How and When to Fertilize Your Orchids
Everyone has a favorite fertilizer or supplement. How you fertilize depends on what kinds of orchids you grow and how and where you grow them.
Give Me Some Air
The Importance of Humidity and Air Movement
Heating and air conditioning both dry the air significantly, try adding humidity trays or a humidifier. Orchids adore constantly moving fresh air, crack open a window and add fans to keep air moving. (May 10)
You must balance light, water, nutrients and air. The best orchid growers know that if they increase or decrease one of these elements, they will have to adjust the others accordingly.
Our orchids talk to us, we just have to understand what they are saying. Learn to recognize orchid symptoms,
both benign and acute, what they mean and how to treat them when necessary.
Growing Different Types of Orchids
If you are new to the orchid hobby, your first plants are likely Phalaenopsis. The moth orchid has become the darling of the commercial pot plant market for orchids. And for good reason. (May 11)
Queen of the Orchids
Although phalaenopsis may be responsible for the current popularity of orchids as house plants, for many people, the image of an orchid flower is a Cattleya, such as Cattleya schroderae pictured at left. (Jun 11)
Dendrobium is a vast and diverse genus of orchids found throughout Asia and the Pacific Islands. There is a species or hybrid for nearly every taste or growing condition. (Jul 11)
While phalaenopsis are elegant and cattleyas are flamboyant, oncidiums are fun. Oncidiums come in many forms and, as a result, go by various nicknames: Spider Orchids, Pansy Orchids, Dancing Ladies. (Aug 11)
Basic Culture of Paphiopedilums
The lips of paphiopedilums are pouches which make them easy to recognize. Because the pouches in some paphiopedilums resemble footwear, they are informally called "lady slippers." (Sep 11)
Orchid Pests and Diseases
Based on past experience we have come to expect an outbreak of black rot under these type of wet, humid conditions. Pythium ultimum (and/or Phytophthora cactorum) is ruthless and can destroy a collection. (Jun 12)
The most commonly encountered insect pests...aphids cause damage to plants by sucking fluids from them... mealybugs are closely related to scale and feed on plant juices... thrips are the most insidious. (Aug 10)
Colonies of scale can become entrenched at the base of a pseudobulb or under sheaths. You may not notice until the pests have done their damage. While scale can be found on flat surfaces of leaves, the worst damage is done at the base of pseudobulbs. (Sep 10)
Unless you have really good eyesight and a strong magnifying lens, you may never even see a spider mite. The first thing that will alert is the silvery stippling on the underside of orchid leaves. (Oct 10)
Slugs and snails feed mainly at night, or on dark days. Their damage is easy to spot. If you find irregular holes with smooth edges in leaves and flowers you should suspect slugs or snails as the culprit. (Dec 10)
Can Spread Through Your Orchid Collection
While weeds will grow quickly on their own, they can be even more vigorous if you fertilize your orchids regularly as you ought to. Eventually the weed roots can completely fill a pot and use up all of the water and nutrients intended for your orchid. (Mar 11)
Seasonal Orchid Care
Fluctuating temperatures and changing light levels are reducing the amount of water and fertilizer your plants require. Phalaenopsis are spiking so stake the spikes for best flower presentation. (Dec 09)
