Polaris Butternut Squash is a hybrid, medium-sized butternut squash known for its high yields and uniform size. This is a Waltham-type butternut with a slender neck and enlarged bottom end. Fruits average 4 to 5 lbs and have a cream colored exterior with a bright orange interior. Plants are vining and provide excellent ground cover when planted densely. Plants will produce 4-5 fruits per plant. Polaris Butternut Squash is an improved variety that has shown to be resistant to cracking. These winter squash store very well and have a great texture for cutting into cubes for roasting or making soups.
Polaris Butternut Squash may be direct seeded or transplanted, although we highly recommend direct seeding. To ensure a good stand, we recommend planting seeds every 12″ along the intended row. Once plants emerge, thin plants to one every 2 feet. Winter Squash can be susceptible to plant diseases like downy mildew and powdery mildew if leaves receive excess moisture. As a result, we recommend using drip irrigation on winter squash to reduce plant moisture and feed plants more effectively. During periods of heavy rainfall, using a fungicide like Liquid Copper can help to alleviate disease pressure as well.
Winter Squash are a crop that will produce a one-time harvest at the end of the growing season. They should be harvested when plants die back and the fruits obtain their full color. Stem hardness is also an indication of fruit maturity. Once stems harden, fruits are ready for harvest using a set of pruning shears. Winter Squash can be stored in a cool, dry place for several months, depending on variety and sugar content. Once fruits are harvested, remove the plants from the garden to prevent any fungal spores from overwintering and becoming a problem in future years. Proper crop rotation is extremely important with all pumpkin varieties to reduce disease and pest pressure.
