Frequently Asked Questions

How many Courgettes can I expect from one plant?

Courgettes are incredibly productive — one plant can produce an abundant harvest all season, so most gardeners only need one or two plants to keep a household well supplied.

Why is powdery mildew so common on Courgette leaves?

Watering at the base rather than overhead helps prevent mildew — wet foliage combined with the plant's dense leaf canopy creates ideal conditions for the fungus, so directing water to the soil is the best preventive step.
