Holly Trees Light Green and Wilting in Heat: Water Deeply, Not Disease

Two of three hollies light green and wilting in 100°F Kansas City heat—middle tree fine (more protected).

Diagnosis

Heat stress, not disease. Pathogens inactive at 100°F; they need moisture.

Action

• Water deeply 1–2 times/week (slow soak to reach deep roots).
• Use soaker hose, low sprinkler, or move hose every 5 min around root zone.
• Do not fertilize now.

Trees vary in microclimate exposure; edge trees suffer more.
