My wife and I planted some tomato plants into large containers a little prematurely. I was in the progress of building a greenhouse and promised her I'd get it done...2 weekends ago! Well, one of our Early Girl plants is getting extremely long and lanky and is unable to support itself already with no fruit. Can we "lop the top" off of it in order to shorten it and maybe get it to bush out a little more or would that be detrimental to the plant? It's going in the new greenhouse tomorrow or Sunday for sure!!!
