Heavy feeder — add generous compost at planting. Avoid excess nitrogen once flowering or you'll get lots of leaf and few fruit.

Succession Planting

Sow every 4 weeks

Sow a second batch 4 weeks after the first. Zucchini plants tire and become disease-prone by late summer — a second sowing gives you fresh, productive plants for the autumn harvest.
