Winter squashes are incredibly flavorful, and growing them is a joy. There’s nothing more American than apple pie. Or is there? Winter squashes belong to the fall season—and to us—in a way that apples (a transplant from Eurasia) never will. Native Americans domesticated squashes from indigenous varieties hundreds of years ago, so this vegetable is built to thrive here. Besides that, who can imagine Thanksgiving without pumpkin pie?
There’s more to the world of winter squash, though, than farm-stand pumpkins. Hundreds of varieties exist, but you’ll rarely see most of them at your local grocery store. They include everything from garden behemoths, like ‘Gill’s Blue Hubbard’, to the bump-rinded ‘Marina di Chioggia’. Best of all, winter squashes are incredibly flavorful, the best ones tasting like chestnuts or sweet potatoes. Growing winter squash is a joy and is fairly easy if a couple of basic rules are followed.
Increase Yields with Proper Spacing
- Warm Soil: Direct-sow or transplant seedlings only after the soil has warmed to at least 70°F. Squashes do not tolerate cold temperatures.
- Starting Seeds: In short-season areas, start seeds indoors three weeks before the frost-free date in spring, but no earlier because older transplants will produce poorly.
- Ideal Garden Spot: A garden in full sun with warm, well-drained, fertile soil that’s slightly acidic (pH of 6.0 to 6.8) is perfect for squashes.
- Soil Amendments: Using compost and soil amendments usually eliminates the need for synthetic fertilizers, which can lower fruit quality and yield.
- Spacing: Space plants far enough apart to give them ample room to flourish. Most winter squashes need 10 to 12 feet apart. Semibush types can be spaced about 8 feet apart, while bush varieties require about 6 feet.
- Harvest Time: A winter squash is ready to harvest when it resists being punctured by a thumbnail.
- Post-Harvest Care: Cut the fruit from the vine and move it to a well-ventilated place out of direct sunlight.
- Cleaning: Clean the squash in a 10% chlorine-bleach solution to reduce the chances of mold ruining the fruit.
- Handling: Handle with care, avoiding damage to the stem to prevent disease.
- Storage: After curing for two to three weeks, store your winter squash at 50°F to 60°F with a relative humidity of 50 to 70% until ready to use.
- Planting Methods: Squashes can be planted in hills (mounds of soil) or drills (trenches). Hills improve soil drainage.
- Black Plastic Mulch: Use black plastic mulch to increase soil warmth, conserve moisture, and protect against soil-borne diseases and insect predators.
- Floating Row Covers: Cover newly planted seedlings with floating row covers for added protection and warmth.
- Pruning: As plants grow, prune off any defective fruit but avoid pruning the vines to maintain yield and quality.
- Pest and Disease Management: Use crop rotation, good garden sanitation, and mechanical barriers like row covers and aluminum foil wrapped around stems to protect plants from pests and diseases.
- Cool Climates: C. maxima varieties like ‘Buttercup’ and ‘Sibley’ tolerate cool temperatures best.
- Tropical Climates: C. moschata varieties such as ‘Canada Crookneck’ and ‘Musquée de Provence’ perform well in damp, tropical locales.
- Warm, Dry Climates: C. argyrosperma varieties like ‘Tennessee Sweet Potato’ and ‘Green Striped Cushaw’ are suited for warm, dry conditions.
- Hot Climates: C. pepo varieties, including popular pumpkins like ‘Winter Luxury Pie’ and ‘Sugar Loaf’, thrive in scorching climates.
