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.

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.
