So I have read the archives about pruning. I am working with a space thats about 4 ft length and 4 ft width. However, it is only 3 feet high. If i prune the tops of my plants, does this encourage the plant to grow wider or does it just make the plant have more branches to grow upward??? How soon can you start to prune - from the start of branch growth or do you have to give the plant some time to gain a little strength??? Thanks for the replies.
