Growing zucchini (Cucurbita pepo) in a garden is very easy and a zucchini plant can produce large amounts of delicious squash.
How to Plant Zucchini
When planting zucchini, you can plant them either as individual plants or grouped on hills. How you grow zucchini squash is up to you, based on how many zucchini plants you intend to grow and how much room you have to grow them.
After the chance of frost has passed, plant 2-3 seeds 36 inches apart. The seeds should be planted about an inch deep. Thin to one plant per spot once the seeds have sprouted and have grown their first set of true leaves.
Once seedlings are established, mulch around the plants. Mulching helps to keep the ground temperature stable and also helps the soil retain water. These two things will help the zucchini plant have an earlier and larger crop.
Make sure that your zucchini plants get at least 2 inches of water a week. If you do not receive enough rainfall to do this, supplement with manual watering. Use a soaker hose or other method to water the plants below their leaves. Watering using a sprinkler can cause the zucchini plants to develop powdery mildew.
Harvest zucchini squash when the fruits are small. This will result in a more tender and flavorful squash.
