South Anna Butternut Squash is an open-pollinated, butternut squash variety derived from a cross between a Waltham Butternut Squash and Seminole Pumpkin. It has the shape of a traditional butternut squash with the disease-resistance and vigor of the Seminole Pumpkin. This variety exhibits exceptional resistance to downy mildew and performs well in hot and humid climates. Fruits have a slightly darker exterior than traditional butternut squash, but with excellent flavor and storage potential.

South Anna 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.

Great Butternut

Best quality and taste I have ever grown.

5 out of 5

Best butternut I've ever tasted and grown. This squash has a strong butternut flavor. The flesh is a beautiful darker orange than other varieties. I've had zero problems with disease - no need to spray (I use organic sprays). And they can grow to be a nice size. I had a few that were 14" long. Also, the storage length is excellent. I ate my last squash one year after harvest but it was just starting to rot and so I used the good part for soup. I would say 10 months is the storage limit. This is my go-to variety for butternut.
