'Tromboncino' Squash problems — and how to fix them

'Tromboncino' Squash (Cucurbita moschata 'Tromboncino') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Powdery mildew

White powder on leaves late season, though moschata types resist it better than zucchini. Space plants, water at the roots, and remove badly affected leaves.

Poor pollination

Fruit aborts when few pollinators visit the separate male and female flowers. Encourage bees or hand-pollinate by transferring pollen with a brush in the morning.

Vine outgrowing its space

The plant climbs aggressively and can swamp a small bed. Give it a robust trellis and tie in or pinch the leading shoots to control spread.

Slugs and snails on seedlings

Young plants are vulnerable to grazing. Protect new transplants with barriers or traps until they are established and climbing.
