Powdery Mildew on Pumpkins: Treatment and Prevention

Key Points

Evening watering = mildew highway
Start preventive spraying early summer
Once infected, very hard to cure
Local garden centers carry fungicides

Your hot, humid Connecticut summer is perfect mildew weather. Act fast — it spreads rapidly in these conditions.
