Summer Defoliation: Humidity, Fungicide Gaps, and Foliar Feeding for Recovery

Gardener (location unspecified) loses all leaves by late summer every year—climbers, bushes, all types. Bare stems with flowers remain. Fertilizer and TLC don't prevent it.

Root Cause: Fungal Pressure + No Spray Program

Humid climates = relentless black spot, mildew. No fungicide = guaranteed defoliation. "Every two weeks" is the minimum.

Recovery Spray Protocol

1. Start now: Systemic fungicide (Immunox, Ortho Disease Control) per label.
2. Add 1 tbsp Miracle-Gro per gallon – foliar feeds push new leaves fast.
3. Continue feeding/watering – monthly liquid fertilizer.
4. Rotate fungicides mid-season (different FRAC codes) to prevent resistance.

Fall Payoff

Cooler weather + new foliage = lush fall bloom. But prevention starts at spring leaf-out. Next year: spray before spots appear.
