This is my question. I have a giant pumpkin vine growing on a compost mound. The vine is maybe 20 feet long with a single fertilized female near the growing tip. Despite precautions, SVB has attacked the plant (I have them bad in my area). Most of the damage is in the first 50% of the vine, with really bad splits/rottting/frass near where the main stem comes out of the growing mound. It seems to me that the main stem is going to break off entirely as time goes on. And please don't tell me about cutting the borers out of the vine blah blah because I know all that stuff and it never really works anyway (believe me I am well-versed in SVB). What I want to do is whack the oldest half of the plant, hoping that the secondary rooting that has taken place all along the buried vine will sustain the youngest 50%. Will this work, or not? Thanks for any comments.
