When should I prune spaghetti squash?
Midsummer once fruit has set. Pinch or cut the growing tip of the main vine beyond the fruit you want to mature. Remove excess lateral shoots and any dead or badly diseased leaves.
How often does spaghetti squash need pruning?
Once mid-season, with tidying as needed. Spaghetti squash vines grow vigorously and benefit from tip-pinching once 2–3 fruits have set, stopping further vine spread so energy goes to maturing fruit. Remove crowded foliage to improve air circulation and reduce mildew. Pruning is helpful but not mandatory — plants still fruit well with minimal intervention in open gardens.
