Burford Holly Sudden Leaf Drop: Temperature Shock Response

Ralph (middle TN): small Burford holly dropping new leaves (6-8" new growth). New stems healthy. Last week: all new leaves dropping, old yellowing. No spots. Fallen leaves black at base (petiole).

Expert Assessment

Steve: not disease. Temporary "shock." Sudden temperature drop? Especially if well-established. Review recent sprays.

Key Insight

Black petiole base on fallen leaves = abscission zone discoloration from rapid senescence. Temperature shock triggers coordinated leaf drop. New growth health indicates recovery capacity.
