About

The Squash That Never Quits

Zucchini belongs to the same species as many familiar squashes and pumpkins, but it has been selectively bred for speed and prolificacy. Under good conditions, a single plant can yield 6-10 pounds of fruit per week at peak season - enough to keep the whole neighborhood fed.

Most gardeners grow the classic dark-green cylindrical types, but yellow, round, and striped varieties are equally easy and add visual interest to the harvest basket. All taste best harvested young, around 6-8 inches long, before the seeds and rind toughen.

How to grow

Planting & care

Start seeds directly in the garden after the last frost date, when soil has warmed to at least 60 F. Sow 1 inch deep in hills of 2-3 seeds spaced 3-4 feet apart, thinning to the strongest plant per hill. Zucchini is a heavy feeder - work a generous amount of compost into the planting hole and side-dress with balanced fertilizer once flowering begins.

Water deeply and consistently at the base of the plant, keeping foliage as dry as possible to reduce powdery mildew risk. Mulch around plants to conserve moisture and suppress weeds. Harvest every 2-3 days once fruits set - missing even a few days lets them balloon into marrow-sized clubs that signal the plant to slow production.

Good to know

Pollination Matters More Than You Think

Zucchini produces separate male and female flowers on the same plant. Male flowers appear first and drop off - that is normal. Female flowers follow, identifiable by the tiny proto-fruit at their base. If early fruits shrivel and fall, poor bee activity is usually the culprit. Plant flowers nearby or hand-pollinate with a small brush in the morning to guarantee a set.
