Winter Squash - Pink Jumbo Banana

Cucurbita maxima

HEIRLOOM -As the name suggests, this vining plant produces lovely pinkish-orange fruit that are rather banana shaped, weighing around 25-40 lbs. Sweet flavor with dry flesh, excellent for baking and roasting; good in sweet or savory dishes. Stores well.

Contrary to the name, winter squash is actually grown in the summer, started the same time as summer squash, but it takes much longer to mature. When it is ripe the fruits will have a hard outer shell and store all winter. Plants are known for their unwieldy vines that will stealthy claim ownership to any garden space they have access to so give them their space. All squash are symbiotic members of the “Three Sisters” (along with Corn and Beans) in Native American agriculture. Corn provides a pole for vining beans which in turn provide nitrogen for the heavy-feeding corn. With their numerous large leaves, squash shades out the weeds and helps retain moisture in the soil for all. Nutrients: vitamins A, C, and B, potassium, manganese. ( 5 Gram Packet)

Site Selection

Winter squash is a frost sensitive annual that prefers full sun and fertile soil that is consistently moist, but well-drained. Choose an area with plenty of space for the sprawling vines.


Direct-seed outdoors once the danger of frost has passed and soil temperatures have warmed to at least 65˚ F for 2 weeks. Optimal soil temperatures for germination are 65-85˚F. Covering the area with black plastic can warm the soil and speed up the growing process. Plant seeds in hills (which warm quicker, drain better) or rows. Space hills 4-8' apart and plant 4-5 seeds ½-1" deep. Seeds will sprout in 5-10 days. When seedlings are 3-4" tall, thin by snipping to 2-3 plants per hill. In rows, plant seeds 6-8" apart with rows 4-5' apart. Thin seedlings in rows so mature plants are 18-36" apart. Mulch around plants to conserve moisture and reduce weeds.

If in an area with a short growing season, seeds can be started indoors 3-4 weeks before the last frost date. Sow seeds in 2-3" pots. Transplant outdoors as you would direct seeding.


Winter squash is typically ready for harvest in 90-115 days. Harvest winter squash in fall before frost, when the rind is a consistent deep color and very firm. If in doubt, open one before harvesting others. For some varieties, flavor will improve with storage.
