Tromboncino squash is a vining variety of winter squash (Cucurbita moschata) known for its long, trumpet-shaped fruits that can reach 30-60 cm in length. It is a heat-loving annual that produces edible, mild-flavored flesh suitable for cooking and storage, with excellent productivity when provided proper support and warm growing conditions.

Start Tromboncino squash indoors about 3 weeks before your last frost, keeping seeds in warm soil (around 20–25 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 90 cm apart. It is frost-tender, so don't plant out early. Expect to harvest in roughly 100 days.
Tromboncino squash seed rarely stays viable beyond 4 years — track what's still worth sowing.
