Pruning Dead Squash Leaves After Powdery Mildew

Remove and Destroy

Cut off dead/diseased leaves at base. Bag and trash—don't compost. Spores survive composting.

New Growth Is Good

Fresh vines mean plant is fighting back. Support with:

• Potassium bicarbonate spray (preventative).
• Base watering only.
• Thin crowded areas for airflow.

When to Give Up

If no new growth after 2 weeks, plant is done. Remove entirely, rotate crop.
