Apply a nitrogen rich fertilizer, at 1/4 strength of the manufacturer's recommended dosage, to the soil around the orchid plants every time they are watered. Allow the soil around the orchid plant to dry out between watering. Apply the fertilizer to the soil right after watering. Use a teaspoon to administer the fertilizer. If your orchid plants are surrounded by bark, move the bark aside so the fertilizer blends well with the soil and isn't hindered by the bark.
Orchids do not grow in soil. Soil does not allow enough air to flow around orchid roots. There are many materials which can anchor orchid roots while still permitting air to move around them. Ground tree bark and moss are two of the most common.They are often combined with perlite, vermiculite, or charcoal to keep the mix open and permit air flow. Remove the orchid from its pot and clean off the potting media-Water the plant to soften the roots. 2  Give the pot a firm bang against a solid surface. 3  Gently pull out the plant, and remove as much of the potting media from the roots as possible. 4  Rinse away any remaining bark or moss.
