Pruning back tomatoes
I want to trim back the vines that aren't bearing, so the sun can get in at the vines that do have tomatoes, and turn those tomatoes red.
Any suggestions or warnings on how to do this?
I mean, is this like cutting a branch of a tree, where I should put tar on the wound so beetles and bugs don't get in?
Or do I get a pair of scissors and start amputating?
