How to grow and keep Zucchini happy
Water mounds deeply at least once a week. Pick the zucchini when they are about 15cm / 6in long – if you leave to grow any longer they can become tough.
Avoid watering the leaves as this will encourage powdery mildew and other fungi. Water below the leaves in the evening or early morning. Water very deeply at least once a week.
How to sow and germinate Zucchini
Will not tolerate any frost. Plant seed or transplant outside after the absolute last chance of frost has passed. Sow 5-6 seeds in hills in well-drained fertile soil and full sun. Thin to three plants per hill. If you wish to start plants indoors, start them 3-4 weeks before last frost using peat pots. Make sure to weather them before setting into the ground.
How to transplant Zucchini
Plant out in “mounds” about 1m (3 feet) apart. Thin to two plants per mound. Disturb roots as little as possible while transplanting.
