Mix this into the garden soil thoroughly. Water deeply and let soil sit for one week. Compost is rich in beneficial organisms that will increase soil fertility immediately. Organic compost is easily made in your garden and is available at garden centers.

There are heritage variety seeds available that are open-pollinated and create a very durable squash. Older heirloom varieties include 'Hubbard '. Plant seeds according to package directions, ½ to 1 inch under the ground. Seedlings appear within five to 10 days. Thin to 18 inches apart when plants are 2 to 3 inches tall.

Water

Irrigate squash plants deeply, thoroughly and regularly. Mulch squash plants with straw, newspaper or black plastic to keep moisture in the ground and conserve water. A mulch cover also suppresses weeds. Watch for wilting leaves during hot weather. Some gardeners use a soaker hose to provide constant irrigation to plants.

Squash are subject to mildew if the leaves remain wet at night. Water early in the day so upper parts of the plant can dry as quickly as possible. If plant becomes infected, remove the leaves and vines that are damaged.
