It is important to keep your vines under control.  When your plant initially grows, you will see the main vine.  Coming off of the main vine are the secondary vines.  Make sure you reposition the secondary vines to be at a 90 degree angle with the main vine.  Coming off of the secondary vines are tertiary vines.  You will need to cut any tertiary vines as soon as you see them.  The tertiary vines just absorb the nutrients that the rest of your pumpkin plant needs.  Make sure you prune or cut off any tertiary vines.

It’s amazing how fast the vines grow once you’re in the full swing of the growing season.  You will need to check for tertiary vines every other day to keep them under control.
