        Buy seed via mail-order or at the nursery. Purchase plants when they appear in the nursery.

    • Plant

        Plant starting mid-month in a rich, well-drained soil in a full-sun location with good air circulation. Space plants 4 to 5 feet apart.

    • Sow Seeds

        After mid-month, sow seed outdoors in containers for transplanting later, or directly in the garden. Seed-starting mix should be well-draining. Ground location requires full-sun, good air circulation and rich, well-draining soil.

    • Fertilize

        After plants become established, feed once this month with an organic vegetable fertilizer.

    • Water

        Keep the soil most but not soggy. Droughted plants will stop producing. Foliage is susceptible to fungal infection, so avoid splashing water onto leaves when watering.

    • Mulch

        Apply a 1- to 2-inch layer of compost or shredded bark to the base of the plant, spreading out 1 to 2 feet.

    • Pest/Disease Inspection

        Check for squash bug, which will feed on plant vines and fruit and cause leaves to wilt. Also look for signs of powdery mildew, which is a powdery coating that appears on leaves.

    • Treat for Pest/Disease

        Control squash bugs by destroying their eggs, which are yellow-to-brown clusters that appear on the underside of leaves. Trap adults under boards or newspapers at night and then collect and destroy them in the morning. There are also insecticides labeled for use on squash bugs. Control powdery mildew by avoiding overhead watering and getting squash leaves wet, especially later in the day.

    • Transplant

        Transplant seedlings starting mid-month in a rich, well-drained soil in a full-sun location with good air circulation. Space plants 4 to 5 feet apart.

Trap adults under boards or newspapers at night and then collect and destroy them in the morning. There are also insecticides labeled for use on squash bugs. Control powdery mildew by avoiding overhead watering and getting squash leaves wet, especially later in the day.

    • Transplant

        Transplant seedlings in a rich, well-drained soil in a full-sun location with good air circulation. Space plants 4 to 5 feet apart.

    • Harvest

        Harvest zucchini when it is small- to medium-sized, at which point it is tender. Although you can allow the fruit to grow large, doing so may cause the plant to cease production.
