Hazelnut Seedlings Wilting in Heat — Too Many Leaves, Not Enough Roots

Newly Planted Hazelnuts Droopy Despite Wet Soil — It's Transpiration Overload

Two 12–16" hazelnuts, planted spring, healthy until hot spell after cool wet spring. Soil moist, mulched, full sun. Leaves limp, slightly curled, not brown. One with more leaves is worse.

Diagnosis: Leaf Area > Root Capacity

Cool spring = lots of leaves. Sudden heat = roots can't supply water fast enough. Leaves lose turgor.

Fix: Reduce Leaf Load

• Remove ⅓–½ of leaves (oldest/largest) on each tree.
• Wait 1 week — wilting should subside.
• Roots catch up; remaining leaves firm up.

Follow-Up: Fungal Spots on Other Trees in Cool Wet Weather

• Shothole on plum: Minor, cosmetic. Copper spray at leaf fall helps.
• Rust/brown spots on others: Cool rain = fungal leaf spots. Copper spray now (safe, organic-approved) protects new growth.
• Avoid Captan if you want low-toxicity.

Thin the canopy, spray copper, wait for heat — trees will thrive.
