The Six Most Common Easter Lily Problems
Height control on Easter lilies is an annual problem. This is especially the case on late Easters as we have had and will have! The two traditional ways in which Easter lily height is controlled is through A-Rest applications and/or by using DIF. Height control using DIF is preferable. A-Rest tends to increase lower leaf yellowing late in development, i.e. from visible bud stage until flower. The more A-Rest you use the greater the potential of this problem. However, large negative DIF environments will cause downward leaf curling which can be unsightly.
