Overview
Zucchini are high-producing members of the squash family, and are summer garden staples. High in antioxidants and Vitamin A but low in calories, Zucchini is a healthy addition to every home garden.
Conditions
Zucchini squash thrive in warm summer conditions. For soil, use a fertile well-draining potting mix that’s tailored for vegetables. Zucchini will need ample feeding throughout growth, as the large fruits need plenty of nutrients. For best growth, provide full sun (6+ hours of direct sunlight per day).
Planting
Plant seeds outdoors directly in the garden once warm weather arrives. Use our grow calendar tool to find specific planting dates for your region! Seeds germinate in 7-14 days.
Plant seeds in clusters of 3, each ½" deep, spaced 24-36" apart. Thin to one plant per cluster as seedlings start to grow.
Care
Keep your zucchini well-watered, especially during hot summer months. Plants tend to produce only male flowers at first, but female flowers will come soon after. If pollinating insects are thin on the ground – or rather the air – you can hand pollinate flowers by transferring the pollen from a male flower directly to an open female flower.
Pests & Diseases
Powdery mildew can be an issue on the leaves later on in the season. Keeping plants well-watered and leaving plenty of space between them for good airflow should slow the spread of this disease. If your zucchini does get powdery mildew, don’t worry too much, as plants will usually cope.
Harvest
Harvest regularly, 2-3 times a week, once plants begin to produce. Cut or gently twist off fruits when they have reached the desired size. Male flowers can also be clipped off and eaten, but do not clip female flowers or more fruit will not be produced!
