Summer and Winter Squash

Summer Squash

Summer Squash

All summer squash (straight neck, crookneck, bush scallop, and zucchini) are actually true pumpkins. They crosspollinate with each other as well as Halloween type pumpkins, spaghetti squash, and small ornamental gourds. All this crossing does not affect the quality of the current season’s production.

Summer squash have a tender skin and are harvested at an immature stage, generally within 4 to 6 days after bloom. The plants are bush type rather than vining and are suited for small gardens. Most new varieties are hybrids.

Summer squash have separate male (attached to the plant by a thin stem) and female flowers (small squash behind the yellow blossom) on the same plant and depend on bees for pollination. Hybrids may produce a few female flowers before male flowers appear, and without pollination, these fail to develop into squash.

Plant summer squash seeds in hills about 3 feet apart, with 3 to 4 seeds per hill or in a row with single seeds spaced about 1 foot apart. Space single plants about 3 feet apart. Crowding leads to low production and disease.

Squash do well on black plastic mulch in spring, especially when planted early. They benefit from warm soil and lack of weed competition. Fall squash can be grown by planting seeds in August, but mosaic virus has been a serious problem in recent years.

Side-dress plants with a nitrogen fertilizer when they have several leaves but before they start to bloom.

Proper harvesting is important for continuous production. Remove all large and overmature squash. This problem is more serious with zucchini than with other types of summer squash.
Several serious insect pests attack squash plants: spotted and striped cucumber beetles, squash bugs, stem borers, and pickleworms. A regular spray program with carbaryl (Sevin) helps reduce damage from these insects.

Disease problems are mainly fruit rot on crowded, shaded plants and mosaic virus.

Winter Squash

Winter Squash

These hard-shelled squash are grown for harvest in fall and storage through early winter months. Acorn and Butternut are the two most popular types, but the group includes many others, such as buttercup, spaghetti, hubbard, banana, marrow, and turban. Some of the pumpkins, such as cushaw and Kentucky Field, are treated as winter or storage squash. An odd assortment of local squash called “aboveground sweet potatoes” fall into this group.

Most of these squash have strong vining plants. The fruit range in size from the small acorn and hybrid Early Butternut to the large banana and hubbards. Winter squash planted in spring along with summer squash mature in midsummer. These fruit lack the eating quality of those produced on plants from seeds planted in late June or early July along with Halloween pumpkins.

Delay harvest until the fruit rind is very hard and vines begin to die. Immature fruit of most varieties are tasteless. Yellow acorn varieties are edible at all stages of maturity. All winter squash are pollinated by bees and require 60 to 70 days from pollination to maturity.


  • Early Butternut Hybrid—mature fruit are tan; excellent flavor and texture; stores well; viney but not overly vigorous; AAS 1979.
  • Sweet Mama—hybrid; dark green; 2 to 3 pounds; flattened; round; Buttercup type fruit; orange flesh; stores well; vigorous vines; AAS 1979.
  • Table Queen—acorn type; small fruit; dark green; deeply ridged; smooth and hard; yellow flesh; bush type plant.
  • Vegetable Spaghetti—fruit 8 to 10 inches long, 3 pounds; yellow when mature; cooked flesh is greenish-white, spaghetti-like strands; flavor is bland; prolific vine; 90 days; orange-fleshed type also available.
  • Waltham Butternut—large, tan fruit; 3 pounds; uniform shape; orange flesh; stores well; vigorous vine; AAS 1970.

Autumn is officially here! It’s not hard to love this time of year. Temperatures are cooling, leaves are changing, and there will be more branches than foliage soon. It’s hard not to love this time of year! As we close out this calendar year, it’s easy to convince yourself there’s not much to do in the yard. Take a break, but also take time to check off these tasks

With the fall season slowly creeping in, there are many things to look forward to, including the drop in temperature. I enjoy watching the leaves change color and drop, too. That also means now is a great time to pull out your rakes, garbage bags, and compost bins and prepare to remove the leaves in your yard! Here are a few other things for you to accomplish in your garden and landscape during the month of September.

When members of the Jackson chapter of Alpha Kappa Alpha sorority brainstormed ways to serve their community, they decided to start a gardening project. Their plan was twofold: grow fresh produce for members of the community who could not get to the grocery store on a regular basis; and get community members involved and teach them how to grow produce. But they soon discovered they were going to need some guidance.

After a relatively mild summer, heat and humidity have arrived in full force in Mississippi. Going outside during the afternoon is miserable these days! If you’re like me, I try to get all my outdoor activities wrapped up in the morning or late afternoon to avoid the heat. Be sure you can recognize the signs of heat-related illness, and remember to drink plenty of water anytime you’re outside! Hydration is important!
