I have lost about 1/4 of my main vine leaves randomly through out the summer (dogs, pants clipping them, and other accidents). I have read to clip tertiary growth from the 2ndary vines. Do these 2ndary and tertiary vines produce little enegy for the fruit? I understand dead heading, but in a case like mine with many of the main vine leaves missing, would it be beneficial growing out more 2ndaries and a few tertiaries to make up for lost energy? Thanks

In common plant patterns tertiary growth overlaps established growth. The plant begins to compete with itself for sunlight and the airflow is reduced, creating an environment for disease.

It isn't unusual for growers to use tertiary vines to fill larger spaces left by dead or trimmed leaves. A practice used on the 1725 Harp was to grow the tertiary vines from the first two secondaries backwards - to fill in the blank space.

Another reason for terminating the vines is that they begin to grow feverishly about this time of year when the ideal plant should be sending all of its energy to the pumpkin.

With as much time to grow as we have, I think it would be a good investment to let them fill in some of your open space.

Thanks Newman, that was what I was hoping to hear. I have 2 terts I am slowly moving into open spaces where the ground dries out quick. From what I can find is there needs to be a balance with the excessive growth while growing fruit, but being able to maintain level amounts of harnessing energy.

BTW, are you goin to Republic this year for the weigh off? I will probably do a local smalltown one here or in Illinois, but best of luck to you.
