How to Plant & Care for Zucchini


Zucchini are a prolific summer squash that are enjoyed fresh or cooked. Excess zucchini can be pickled, canned or frozen for future use. The zucchini blossoms are also a delicacy, often prepared battered and fried. A few plants will supply a family and friends with zucchini and blossoms. Plant zucchini after the last frost date in the spring through midsummer. Sow seeds directly into soil that has warmed to 70 degrees. Seeds sown indoors do not transplant well and often don't survive. In cold areas, cover the soil with black plastic mulch for early planting. The black plastic will warm the soil and allow earlier germination.

Step 1

Choose a sunny location with well-drained soil. Dig or till the soil to loosen it.

Step 2

Add a 2-inch layer of composted manure to the garden and mix into the top 6 inches of soil.

Step 3

Plant zucchini seeds in hills spaced 48 inches apart, four to five seeds per hill. Plant seeds at a depth of 2 inches.

Step 4

Water seeds after planting and keep the soil moist until plants germinate. Continue watering zucchini thoroughly as needed to prevent the soil from drying out. Zucchini needs at least 1 inch of water a week.

Step 5

Thin plants to one or two plants per hill when plants are 2 to 3 inches tall.

Step 6

Apply a side-dressing of high-nitrogen fertilizer midsummer. Apply 1/2 cup of 46-0-0 per 25-foot row.

Step 7

Harvest zucchini when they are small and tender, between 2 to 6 inches long. Leaving the squash on the plant too long will discourage future fruiting. Check plants daily; zucchini grow rapidly. Cut zucchini and blossoms mid-day, when plants are dry.

Step 8

Use a sharp knife or pruning shears to cut the stem just above the fruit. Squash blossoms can be cut leaving 1 inch of stem attached. Cut only male flowers unless you intend to limit fruit production. Do not harvest during wet weather.
