Frequently Asked Questions

What pest or disease most commonly affects Cucurbita pepo (Acorn squash type), and what should I do if I see it?

For Cucurbita pepo, powdery mildew is a frequent late-season problem, showing up as a white, dusty coating on leaves. Improve airflow by spacing plants well and remove the most affected leaves early; avoid overhead watering so leaf surfaces stay drier. If it spreads, switch to a labeled fungicide for squash/pumpkin and apply according to the label starting when spots first appear.

How often should I water Cucurbita pepo during the main growing phase?

During active vine growth and fruit set, keep the soil consistently moist but not waterlogged—aim for about 1–1.5 inches (2.5–3.8 cm) of water per week, adjusted for heat and rainfall. Water deeply at the base once or twice a week rather than light daily watering, and let the top few centimeters of soil dry slightly between waterings. When fruits are about half grown, steady moisture helps prevent uneven development.

How can I tell when Cucurbita pepo (Acorn squash type) is ready to harvest?

Harvest at about 90 days when the rind is hard and you can’t easily puncture it with your fingernail. The stem should be slightly dry and corky, and the fruit should have developed the mature color typical for acorn squash. Cut with a sharp knife leaving a short stem (about 1–2 inches), and cure in a warm, dry place for about 7–10 days before storage.
