I've had a 4" diameter x 2" high clear water tray full of U. praelonga for about six months and it has not flowered. it's very densely overgrown with each leaf type (wide shorter blades and the very long grass like blades and some that are half and half). Is there a trick to getting it to flower? My other utrics seem to flower easily but only when their pots get very densely overgrown which this one certainly is.
Will the larger utric species tolerate light fertilizer (urea free orchid fertilizers 30-20-30 or 20-30-30) mixed at 1/4 or 1/8th strength?
The utrics pots usually stand in 1/2" or less of water at all times. 65-80*F night/day. 70-80% humidity & 160 watts of flourescent light. Should the Utric pots be nearly waterlogged at all times for better growth and flowering?
Thanks for any thoughts!
