How to prune 'tromboncino' squash

When the main vine has 4–5 true leaves; side-shoot management ongoing through summer. Pinch the main growing tip to encourage laterals, or keep one strong main vine on a trellis and remove secondary laterals beyond one leaf past a fruit. Snap or cut yellowing leaves at the base cleanly.

Initial training once; ongoing side-shoot removal every 1–2 weeks during fruiting. Tromboncino is a vigorous climbing squash that benefits from training and stem management rather than heavy pruning. Pinch the growing tip after 4–5 leaves to encourage lateral shoots, or train the main vine vertically and remove excessive side shoots to concentrate fruiting. Remove dead or yellowing leaves throughout the season.
