Growing Instructions: Summer Squash & Zucchini

Zucchini and summer squash do not transplant well so it is best to direct sow. They have a short growing season so this isn't an issue in most climates. Wait to plant until the soil temperature is above 60F. If you have a short season, start seeds indoors 2-4 weeks before the last frost.

Plant squash in full sun. They are wide bush-like plants that need space so make sure there is 2-3 feet between each plant. Sow seeds 1” deep. Frequent and consistent watering is important – at least 1” per week. Once the plants start producing fruit, check every day for harvest as it grows fast and furious. Harvest squash while young – once it gets big it loses flavor and gets seedy.

Growing Instructions: Pumpkins & Winter Squash

Pumpkins (and winter squash) need full sun and a long growing season. Start seeds indoors if you are in a cooler climate. They generally need between 70-100 days so make sure you choose a variety that has enough time to reach maturity in your climate or that you are starting them inside soon enough.

Direct sow when all danger of frost has passed. Plant 3-4 seeds 1" deep in large mounds around 6-8' apart. Pumpkins grow on vines that can reach 30 feet long so make sure you have lots of space in the garden for them to stretch out or train the vines to a trellis or support system. This works especially well with smaller pumpkins – larger ones are too big to be supported on a trellis. Another option is to plant them around the edge of the garden and direct the vines around the sides. Pumpkins can also be planted in rows 6'x6' apart.

Transplant seeds when all danger of frost has passed. The seedlings are extremely tender and cold temperatures will kill them. The soil temperature should be at least 65F. Pumpkins need about 2" of water per week. They are heavy feeders and benefit from manure, compost, or other fertilizers.
