11 3"-4" tall. Plant growth regulator applications should NOT be needed at all, unless they are grown very tight
Bud initiation nearly complete, maintain temperature below 65F until done.
10 Check for bud set, if good to go, increase to 65F. Keep greenhouse cooler if ahead of schedule.
9 5"-6" tall. Adjust temperatures as needed. Must now space the lilies to avoid stretching. Or use a PGR spray.
Only apply Fascination (10ppm) to lower leaves 7 to 10 days before visible bud if leaf yellowing is evident.
8 Check for aphids & root problems. Apply systemic or biological pest control sometime during weeks 10, 9, or 8.
Soil test & if leaf scorch is evident, use some calcium nitrate. Make sure to check the EC levels before application.
