How to Grow Orchids on Trees

Select an orchid that thrives in the kind of environment the trees in your garden offer. Vanda, for instance, needs a tree that does not block the sun. Cattleya orchids do well in low light. Ask at the nursery that sold you the plant when its active season begins. If you didn't buy the epiphyte, contact the county cooperative extension office for information on the species.

Set evergrowing orchids on trees any time of the year. Place the plant against the tree bark. Position it so that its blossoms are visible and so that the orchid receives the type of light it requires. Tie the plant to the tree with cotton string. The roots will grab a tight hold of the bark within the year, eliminating the need for a fastener. There is no need to replace the twine after it decomposes.

Mist the orchid with a spray bottle or set a sprinkler to reach the plant up on the tree. Maintain the newly attached epiphyte consistently moist. After its first growing season on the tree, water the plant according to the species' requirement.

Spray a balanced soluble fertilizer, such as a 10-10-10 analysis, on the roots of epiphyte orchids. Apply the nutrient at the lowest rate listed on the manufacturer's label and at the recommended schedule. Alternatively, feed the plant fish emulsion or liquid orchid food.
