Hello, I am new to gardening and landscaping. I just got a couple 4ft topiary tree for outside the front door. These trees are in pots and probably going to be left in pots. I would like some suggestions on how to care for these. How often should I water them, Prun them, and can I put them in a bigger pot so they grow larger? Also how long do these trees take to grow and whats the life expectency? Well thanks for your help ! I told you I was a newby :)
