Flatso Pumpkin is a hybrid pumpkin variety with a flattened shape, similar to the popular Long Island Cheese Pumpkin. Flatso is a popular variety for roadside stands or farmers markets because of its ornamental and decorative appeal. However, it also makes a great pie pumpkin for backyard gardeners.
Flatso Pumpkin has semi-bush plants which produce flat, oval-shaped pumpkins that average 6-8 lbs each. Each plant will typically yield 3-4 pumpkins, which are consistent in size and shape. The stems are thin and are often cut short so that the pumpkins can be stacked for a decorative display.
Pumpkins 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.
Pumpkins 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.
Pumpkins 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.
Pumpkins 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.
