Growing Winter Squash and Pumpkins Vertically

Winter Squash Grown Vertically
Winter Squash Grown Vertically

Growing winter squash and pumpkins vertically can save garden space and help to fight pests.  To grow squash vertically, here a few simple tips to follow:

  • Choosing the correct seed is the best place to begin. To grow squash Vertically choose squash that has a vining habit (sometimes called trailing) and produce small fruit; two pounds or less is recommended. Growing squash that can grow to a hundred pounds or more would be hard to accommodate when building the structure to be climbed and would break from the vines before mature.
  • Site and climbing structure should be properly prepared. The climbing structure should be strong enough to withstand strong winds and the weight of the squash as they reach maturity.
  • The soil needs to be well worked and mounded to allow soil based watering methods, such as trench or soaker hose and provides adequate drainage.
  • The grooming method needs to be adapted to encourage the growth of several small fruits. Many gardeners recommend removing fruit and leaving only one or two on each vine; thus, encouraging a few large fruits.  When growing vertically we want to encourage the growth of numerous small fruit, which will be less likely to tear the vines down or fall off the vine.
  • As squash grow larger and providing additional support for the fruit may be desirable to prevent the fruit from tearing themselves from the vine before mature or falling to earth and breaking or being bruised.
  • With some early maturing varieties picking of fruit may be necessary as the fruit becomes fully mature to reduce weight in the vine and to encourage the vine to produce more fruit. Care should be taken to ensure the fruit is fully mature.

Climatic Considerations for Winter Squash and Pumpkins

Pumpkins Outdoors in Fall

Squash is a warm-season crop. It should not be planted until the danger of frost is past. In the list below, note the species from which each variety has been selected. Some do better in certain climates and have different growing season lengths.

  • C. argyrosperma and C. mixta grow best in hot arid climates like the Southwest United States
  • C. maxima grow best in cooler northern climates, especially along coastal areas of large lakes or oceans where the growing temperature may be more consistent
  • C. moschata are best grown in southern humid climates
  • C. pepo does best in areas in climates which provide even rainfalls and temperature ranges, such as, coastal regions and the midwestern United States.

Cool Storage

Perhaps, the better and most cost-effective way to keep winter squash and pumpkins is cool storage.  For cool storage to be effective the fruit must be consistently stored above freezing and the germination temperature.  Please note, Not all squash store equally well.  With that said, I have stored some varieties a winter squash so long that we have had to eat them just to make room for the New Year’s harvest.

For best results:

  • cure in warm area squash or pumpkins for a week to 10 days,
  • clean off dirt with a damp soft cloth,
  • with a second clean soft cloth wash with 1 cup vinegar to one gallon of water, and allow the skin to dry completely before storage.
  • Store in a cool (40-550 F), dry place to prevent shrivel, lose weight, and to postpone spoilage as long as possible.
  • Position the fruit so that the fruit is not touching one another and so that air can flow freely around the fruit.
  • I recommend placing as many of the fruit where they can be easily seen, for easy inspection for signs for an impending loss. The sweetness and quality of squash or pumpkins often improve, if cured for 2 to 4 weeks, or more in storage.

Where to Store Squash and Pumpkins

where to store your squash is a little less important provided the required temperatures can be maintained. Some of the more common places are root cellars, pantries, basements. Just about any place with a cool constant temperature within the ranges required will do. However, it’s best if it’s a place that’s convenient and semi-protected. You don’t want your squash to be damaged by kids playing or by having to crawl over them to get to something important which might beast stored above are behind them. Perhaps, my favorite throughout the years has been the root cellar I grew up with them in Oregon and I’ve long appreciated their value for storing vegetables of all types including winter squash for long periods of time to do the harshest weather during winter. I have, in places like Virginia and Minnesota, used the basement of the home in which I lived. Pantries can be a little more problematic for a couple of reasons. First, having sufficient space to store all the pumpkins and squash growing volumes at my gardens produce. Second, my pantries are usually attached to the house and tend not to read to retain a constant cool temperature.

Is your storage location too warm?

The best way to tell if your storage location is too warm, other than a thermometer, is that when you break open the squash, if you see seeds that have sprouted, then your storage area is too warm the seeds are germinating.

Where are Pumpkins Native to?

The common species of squashes and pumpkins used by gardeners are native to the Western Hemisphere and wild varieties can occasionally be found in their native environments.

  • C. maxima – Represented by the Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban are varieties thought to have originated in northern Argentina, near the Andes, or in certain Andean valleys. Maxima varieties like cooler climates with regular rainfall.
  • C. moschata – Represented by such varieties as butternut, Winter Crookneck Squashes, and Japanese Pie and Large Cheese Pumpkins are native to Mexico and Central America. This species prefers and tolerates hot growing conditions and longer growing seasons of the southern regions.
  • C.  pepo – Apparently originated in the same general area of Mexico and Central America as C. Maxima and is represented by Golden Acorn, Jack-Be-Little, Connecticut Field, and Delicata. Pepo varieties like cooler climates with regular rainfall.
  • C. argyrosperma –Includes many of the traditional winter squashes known as Cushaws, which have been grown since early times from Guatemala to the southwestern U.S. Members of this species are drought-tolerant and their flesh is generally paler, stringier and less sweet than other types of squash.
