Greenhouse-grown Tapeinochilus ananassae Hassk. were fertilized with 1110, 2220, or 4440 g of Osmocote 17N–3P–10K/m2 per year for 4 years. Plants receiving the medium rate of fertilizer produced the most flowers, while the highest fertilization rate resulted in the fewest. Flower stalk length decreased each year after planting, but cutting back the vegetative shoots to the ground resulted in increased flower stalk length the following year. Fertilization with the highest rate resulted in reduced flower postharvest life, but floral preservatives and ethylene inhibitors had no effect on postharvest life.
