Use caution
Summer squash
Extension guidanceCucumbers and squash share cucumber beetles.
Striped and spotted cucumber beetles feed on cucumber-family crops and can spread bacterial wilt, especially in cucumbers. Planting them together concentrates a shared pest, not a chemical incompatibility.
Spacing: No safe separation distance is established; monitor both crops.
Pests: Scout seedlings early; row covers until flowering are a common tool.
