Heavenly Hubbard Squash is the first hybrid, hubbard squash developed. This is a C. maxima winter squash variety with beautiful, grey to blue fruits. Because it is a hybrid, Heavenly Hubbard produces more consistently-sized, uniform fruits than open-pollinated hubbard squash varieties.

Fruits grow on vigorous vines and average 15 lbs each. Heavenly Hubbard Squash has an exceptional texture and sweet flavor. It may be cut in half and baked for a more traditional, winter squash preparation. But the texture of this variety also makes it a great choice cutting into fries.

Heavenly Hubbard 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 is 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.
