O at each watering. Regular fertilizer will not increase plant height, but high soluble salt will decrease height. High P levels formerly associated with leaf scorch, but the problem was traced to Fl toxicity, and not P toxicity. Include P in the fertility program because it reduces lower leaf yellowing when some PGRs are applied. Dip bulbs in a fungicide and miticide before potting, or drench immediately after potting, to control root rot and bulb mites.
Lilies respond to A-Rest spray or drench.
As a rule of thumb, A-Rest drenches are twice as effective per mg a.i. Some research has shown that triazole fungicides are effective in reducing lily height, either as bulb dips or soil drenches. Plants spaced close together will stretch. After FBI, make sure plants are spaced properly. Flower induction can be achieved with a vernalization treatment or long photoperiods when they follow a period of cold.
