Zucchino Rampicante

Zucchini (Cucurbita pepo) is commonly hit by powdery mildew, which shows up as a white, dusty coating on leaves and can reduce fruit set. Improve airflow by training vines onto a trellis and spacing plants properly, then spray with potassium bicarbonate or sulfur early at the first signs, following the label. Avoid wetting leaves during watering and remove heavily infected leaves to slow spread.

Harvest when fruits are young and tender, typically around 50 days from sowing, usually at about 6–8 inches long and still firm with glossy skin. If you press a thumbnail gently and it punctures the skin easily, they’re at the right stage; if the rind hardens or seeds swell visibly, flavor and texture decline. Check plants daily during peak production and cut fruit with a knife, leaving a short stem to encourage continued flowering.
