Tropical orchids are no more difficult to grow than other plants but their culture is different from that of other plants because most of them are epiphytes or tree dwelling plants. British orchid growers failed during the early 1800's when they attempted to grow tropical orchids under dark, hot, and steamy conditions. They succeeded only when they realized that most tropical orchids grow at higher, cooler elevations and in the upper branches of trees where they manage to get considerable light and perfect drainage.

Light Requirements:

In the greenhouse, tropical orchids require shading to prevent the leaves from overheating. In the house they need the maximum light available. Placing them outside during the summer under the shade of tall trees is very beneficial. Do not place them in full sun because the leaves may burn. Do not place the plants on the ground because insects and slugs can enter the pots and damage the plants. The plants can be suspended from tree branches, chains, strong trees, or other structures using pot hangers.

Temperature Requirements:

In the house place the orchids in a room with relatively cool temperatures to help guard against dehydration. Most orchids need temperatures below the comfort level of humans, especially during night. In greenhouses orchids are kept at 55-65 degrees at night.

Soil requirements:

Tropical orchids need loose mixtures of organic material such as fir bark, tree fern, osumda fiber added with small amounts of peat, perlite, cork or charcoal added. The object is to have a mix that drains well, but holds some moisture. Most commercial orchid growers supply ready-to-use orchid mixes in small quantities. Orchids usually need repotting only once every two to three years.

Watering Requirements:

For watering tropical orchids, it is best to soak the potting mix thoroughly and wait until the surface is relatively dry before watering again. Most orchids in fir bark based mixes will need watering about once every 5 to 7 days.

Fertilizer Requirements:

Tropical orchids can be fertilized safely with a water-soluble urea free fertilizer. You should always water before fertilizing and it is best to under-fertilize rather than over-fertilizing. With the lower light and drier conditions in the house the orchids cannot use as much fertilizer as they can use in the greenhouse. By fulfilling these requirements you too can successfully grow Tropical orchids.
