Overseeding Mold Problem: Stop Overwatering

Fungal Growth from Excessive Overseeding Watering

Southern Ontario homeowner sees mold after watering new overseeding twice daily for five days in low-sun conditions.

Immediate Action

• STOP watering. Let soil dry out.
• Fungus requires constant moisture; drying halts it.
• Do NOT apply fungicide.
• Resume deep, infrequent watering only if needed.
• At this season, further watering may be unnecessary.

Overwatering in cool, shady conditions guarantees fungal problems. The seed needs moisture but not saturation.
