When learning about how to grow acorn squash, the first consideration should be space. Do you have enough to accommodate the acorn squash plant size — which is considerable? You’ll need about 50 square feet per hill with two to three plants in each. That’s a lot of ground, but the good news is that one or two hills should provide plenty for the average family. If the square footage is still too much, acorn squash plant size can still be squeezed in with the use of sturdy A-frame trellises. Once you have allotted space for growing, acorn squash is easy to cultivate. Mound your soil into hill to keep the plant’s ‘feet’ dry. When growing acorn squash, plant five or six seeds per hill, but wait until the soil temperature rises to 60 F. (15 C.) and all danger of frost is past since the seeds need warmth to germinate and the plants are extremely frost tender. These vines prefer temperatures between 70 and 90 F. (20-32 C.). While the plants will continue to grow at higher temperatures, the flowers will drop, thus preventing fertilization. The acorn squash plant size makes them heavy feeders. Make sure your soil is rich and you feed them regularly with a good all-purpose fertilizer. Add plenty of sun, a soil pH of 5.5-6.8, and 70-90 days before the first fall frost and you have all that’s needed for how to grow acorn squash.
