Zucchini
Cucurbita pepo
A single healthy zucchini plant produces 6-10 lbs of fruit per season — and pollination requires both male and female flowers to be open on the same morning, which is why early harvests often fail.
How to care for zucchini
Harvest fruits at 6-8 inches long — leaving zucchini to grow huge stops new fruit production. Hand-pollinate by transferring pollen from male to female flowers with a paintbrush if you see fruit shriveling.
