Hello there. I have a Japenese maple in a 28" pot. I have had it since it was a seedling and have potted it on when necessary. Trouble is that it is so pot bound that the compost feels quite hard on top of the pot. I can't put it in the garden as I don't have room for it. Potting it on isnt possible as the pot would have to be enormous and expensive too. I am wondering if the tree has reached the end or is it ok to be so root bound. It dries out so quickly too. Any advice would be much appreciated.
