When it is getting towards the end of the growing season, is it okay to trim pumpkin vines past where the pumpkins are growing? I have vines growing everywhere and wondered if it was okay to trim back where they are not producing.
In most cases, the plants require some cutting to keep them in control. Every pumpkin plant has a main and a secondary vine that usually grow in opposite directions. Each of these two vines produce shoots (or tertiary vines) which can be selectively pruned as the plant develops. It is best to clip when these new side shoots begin to develop.
In addition to pruning the vines, some gardeners prune the fruit -- selecting a few for special attention and removing the rest.
