Burgess Buttercup Squash is an heirloom, open-pollinated winter squash variety known for its creamy texture and sweet flavor. This a C. maxima variety with fruits that will store for several months when kept in a cool, shaded location. Burgess Buttercup was introduced in 1932 as a substitute for sweet potatoes and has been a favorite of gardeners since!
Burgess Buttercup Squash has vigorous plants that produce vines up to 6′ long. Plants average 4-6 fruits per plant. Fruits have a dark-green exterior with a button on the end, much like our Turks Turban Gourd. Fruits average 5-8″ in diameter and can weigh up to 5 lbs each. In addition to being very tasty, these winter squash are very nutritious and rich in Vitamins A, B, and C.
Burgess Buttercup 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.
