Triamble Pumpkin is an open-pollinated, heirloom pumpkin variety that originated in Australia. In addition to being great for fall decorating, these pumpkins are known for their excellent eating quality. Due to their great storage ability, many people will choose to use them as decorations and then eat them later.

Triamble Pumpkin produces fruits that have a slate blue exterior with three distinct lobes. Plants are high-yielding and fruits average 8 lbs each. The interior of these pumpkins is very dense with lots of meat and a small seed cavity. Triamble can be used for making pumpkin muffins, pumpkin bread, pumpkin pies, and more! The meat also preserves and freezes well for later use.

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.
