When you have two plants right next to each other and one is doing great while the other is
half the size and barely surviving, do you nurse the weak one, or just rip it out?
I almost want to let pests and whatever concentrate their efforts on the weak plants,
but on the other hand, I want the weak plants out so they don't harbor issues.
And then I consider the chance that the weak plants will eventually overcome and bear fruit.
Any general guidelines would be appreciated.
