How to prune pumpkin

Mid-summer, once vines reach 10-12 feet and fruit has set. Pinch or cut the main vine tip just beyond the last fruit you want to keep, leaving 10-15 leaves beyond the fruit for photosynthesis. Remove all secondary (tertiary) side shoots beyond the first or second fruit. Use clean shears to avoid spreading disease.

Once mid-season after fruit has set; monitor and remove excess side shoots as needed. Pumpkins benefit from purposeful pruning outdoors to improve yield and fruit size. Pinch off the growing tip of each main vine once it reaches 10-12 feet to redirect energy into fruit. Remove secondary side vines beyond the first fruit set and prune the vine to 2-3 fruits per plant for larger pumpkins.
