Can/should I repair a damaged spot on the vine
I noticed my pumpkin/kabocha plants have a spot on the main runner that is damaged. I dont THINK it was a squash borer, because this spot appeared right were the plant contacted the rough and sharp edge of a stone which makes the outside of the raised bed the squash is planted in. Also, chickens harassed the bed recently, and they dug beds into the soil nearby, pushing the plant around, tearing up a few leaves, etc.; they might have just stepped on it with their claws or pecked it or something. So I think it's just simply physical damage of one kind of another.
Anyway, would it be a good idea to put some gaffer's tape or something on the damaged spot? Is there any way I can be 100% sure it's not a squash borer?
