I'm in my 3rd year of gardening and have learned primarily through experimentation. I have just learned about "pruning" tomato plants and am thinking this is why I have never had that explosive yield that most people talk about when it comes to tomatoes. Problem now, is, that my plants are already HUGE. Can I prune them now? I am reading conflicting info out there on the interwebs. Some say yes, some say it will stress the plant. What to do? Most people I know are JUST now getting fruits around here so I'm hoping I'm not too late to increase my yield. Thanks!
