Zucchini is the most productive plant in the summer garden — famously prolific once it gets going. The large orange-yellow blossoms, like squash flowers, are beautiful and edible. One plant will produce blossoms daily through midsummer; harvest male flowers freely (those without a tiny zucchini at the base) and you'll have a continuous supply without reducing fruit production.
The challenge is managing production: zucchini left to overgrow signals the plant to reduce flower output. Harvest every 2–3 days and keep the plant in a continuous cycle of flowering and producing small fruits.
Powdery mildew
White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.
Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.
