How to Sow Squash
Sow squash seeds one-inch deep, spacing the plantings about 18 to 30 inches apart in the vegetable garden bed, depending on the variety. Follow the squash seed packet instructions. Allow plenty of growing space for vining types. Where space is limited, grow only the bush varieties in your home vegetable garden.
How to Grow Squash
Water squash plants deeply once a week, applying at least one inch of water. Shallow watering promotes shallow root development that is detrimental to yields. Don't judge the moisture content of the soil by the dryness of the surface, if the soil is dry four inches down, water. If the soil is moist at that depth, the squash plants will be fine. Wilting in scorching, mid-afternoon sun is normal for summer squash. They will recover when the sun goes down. While squash prefers full sun and warm soil, extreme heat and drought can stress the plants, reducing production. Mulch is essential to keep the soil around the roots moist and to regulate soil temperature. When the seedlings are two inches tall, apply a loose mulch of clean straw, hay, grass clippings, chopped leaves, shredded newspaper, or any mixture of these materials. As the plants mature, you can add more mulch to keep them happy. Black plastic mulch is also recommended, especially to warm the soil in the spring.
Harvesting Squash
Here are two things to keep in mind when you harvest summer squash. Cut the fruits from the vine carefully. Using a paring knife or garden shears, cut the stem about an inch above the fruit. Don't try to twist or yank the squash as you could rip the skin or damage the plant.
