Growing Tromboncino — the things that trip people up
- Pick summer squash young and often — a zucchini goes from perfect to baseball-bat in a couple of days, and picking keeps the plant producing.
- Give it room, rich soil, and steady water. Watch for squash bugs and vine borers, and hand-pollinate the first flowers if small fruit keeps dropping.

Common questions about Tromboncino
How long does Tromboncino take to grow?
About 70 days to the first pick, then it keeps producing for weeks if you keep harvesting.
Why pick Tromboncino small?
Young summer squash is tender and best-tasting, and constant picking tells the plant to keep making more. Leave them on and they turn seedy and the plant slows down.
