How to Grow Summer Squash

Summer squash, with their tender flesh and delicate flavor, are a staple in many home gardens. These versatile vegetables can be cooked in a variety of ways and are perfect for use in everything from salads to soups to stir-fries. If you’re interested in growing your own summer squash, here are some tips to help you get started.

Planting Instructions

Summer squash grow best in warm weather and require plenty of sunlight, so it’s important to choose a location that receives at least six hours of direct sunlight each day. They prefer well-drained soil that’s rich in organic matter, so work some compost or well-rotted manure into the soil before planting.

Sow your summer squash seeds directly in the garden once all danger of frost has passed and the soil temperature is at least 60°F (15°C). Plant the seeds 1 inch deep and about 2-3 feet apart, with rows spaced 4-6 feet apart.

Watering Requirements

Summer squash plants need plenty of water, especially during hot weather. Keep the soil consistently moist but not waterlogged. Water the plants deeply once or twice a week, depending on weather conditions.

Fertilizing Tips

Summer squash plants are heavy feeders and benefit from regular fertilization. Fertilize the soil with a balanced, all-purpose fertilizer at planting time, and then side-dress the plants with additional fertilizer once a month throughout the growing season.

Pest Management

Summer squash can be susceptible to a variety of pests, including squash bugs, cucumber beetles, and squash vine borers. Keep an eye out for these pests and take action as soon as you spot them. Regularly inspect the undersides of leaves for eggs and use row covers to prevent adult pests from laying eggs. Handpick and destroy any pests you see, or use an organic insecticide.

Disease Management

Summer squash can be prone to fungal diseases such as powdery mildew and downy mildew. Keep the leaves dry by watering the plants at the base, and make sure there’s good air circulation around the plants. Remove any infected leaves immediately and dispose of them in the trash (not the compost). Consider planting disease-resistant varieties to reduce the risk of infection.

Harvesting Instructions

Summer squash are usually ready to harvest about 50-60 days after planting. Harvest the squash when they are small and tender, about 6-8 inches long. Use a sharp knife or pruning shears to cut the squash from the plant, taking care not to damage the stem or nearby leaves. Regular harvesting will encourage the plants to produce more fruit.

Storage Tips

Summer squash is best eaten fresh, but if you have more than you can use right away, you can store it in the refrigerator for up to a week. Wrap the squash in paper towels or a clean kitchen towel and place it in a plastic bag or container. Don’t wash the squash until you’re ready to use it.
