Summer Squash - Cucurbita Pepo
By, Tom Rood

July 18, 2001

In an era when it was safe to leave car windows down during late summer, the standing joke going around was that you were liable to return to find the front seat loaded with Zucchini summer squash. Zucchini is prolific if grown correctly. Summer squash is not limited to just Zucchini. There are the yellows- straightnecks and crooknecks, scallops, marrows, as well as the proverbial Zucchini. Summer squash comes in a variety of colors from light green to dark green, plus yellow, "striped" and plain and in shapes- elongated to roundish.

Summer squash is an annual vegetable and a neat plant for the family garden because it is usually a bushy plant that doesn't run all over the garden. It is easy to grow requiring just a sunny spot and fairly well drained soil mixed with well rotted manure or rich compost. It wouldn't surprise me at all to find it easy to grow on the back patio deck in a five gallon pail (with drainage holes punched just above the bottom rim) filled with the same soil mix as long as it receives full sun. In the case of compost rather than rotten manure a liberal dose of a balanced fertilizer such as 5-10-5 should be mixed in at planting time. Squash are heavy feeders.

There are so many hybrids available that old time favorites may be hard to distinguish from the newer varieties. Still, many people have their personal favorites. We prefer the Yellow straightneck over the crookneck. For the Zuc's there isn't enough difference, in our opinion, to be worth fighting over.

Summer squash require only from 40 to 50 days to mature. It isn't too late to plant a few seeds if your garden has a sunny spot. If the soil tends to be on the heavy clay side or otherwise poorly drained, make a mound or hill before planting following the advice for soil improvements mentioned above. Plant the seeds one-half inch deep and water well. If an early light frost is predicted, drive a short stake in the ground next to the plant and cover with an old sheet or blanket. The stake will support the cover.
If garden pests become a problem, a dose of rotenone or other dust listed for squash on the label can be used to control squash vine borers and striped and spotted cucumber beetles. The beetles can also spread fungus disease such as bacterial wilt and cucumber mosaic.

Summer squash will continue to produce fruits as long as they are kept picked off. The squash is best eaten fresh and when the fruits are small (4 to 8 inches long). It is amazing how fast the fruits will develop. If allowed to increase to a large size, the flavor isn't as good, the skin becomes tough and the seeds coarse. The flavor peak occurs when the blossom attached to the end of the squash turns brown and dries. They may not be very big at that time but even so that is the best time to enjoy them. Use care in picking the fruit to avoid damaging the vine. A sharp knife is a good idea as twisting the fruit off can damage the vine.

For the chefs amongst us, summer squash is the "darling of gourmets". The blossoms as well as the tiny immature fruits can be prepared in a variety of ways. The blossoms can be cooked tempura-style, sautéed or added to pancakes after the batter is on the grill. The tiny fruits can be included in a stir-fry, added to salads or skewered with other vegetables and meats for grilling.

Recipes for summer squash abound from breads, battered and grilled, sauces, pickles, salads, soups, garnishes, the list goes on and on. Most good cookbooks make interesting reading and include receipts we all think about trying from time to time. So clear the decks for action and surprise everyone with your new culinary skills taking summer squash to new levels of elite dining.
