Frequently Asked Questions

How do you grow zucchini successfully?

Give it rich soil, full sun, steady water, and regular feeding, since zucchini is a heavy feeder. Prune crowded leaves for airflow and pick fruit young to keep it producing.

Why is my zucchini plant not producing fruit?

Often poor pollination or too much nitrogen, which grows leaves over fruit. Hand-pollinate the flowers and use a balanced fertilizer to fix it.

How often should you pick zucchini?

Every day or two once it's producing. Picking young 6-to-8-inch fruit keeps the plant cranking out more and stops giant, seedy squash.
