Diablo Pumpkin is a hybrid, jack-o-lantern type that is ideal for home gardeners and small market farmers. This variety produces the perfect size jack-o-lantern. Fruits are uniform, blocky and round. Diablo Pumpkin is a medium to large pumpkin and averages 15-25 lbs. In addition to its uniformity, this variety is known for its stocky, strong handle. The stems average 4.5″ long which makes it easy to harvest and transport for storage. It is also powdery mildew resistant which makes it a great option for humid growing zones.
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.
