potting and root growth
Hello again. Whilst researching putting small trees in pots (acers in my case), the advice seems to be not to over-pot and not start them off in a pot more than twice the size of the one you bought it in as the tree will simply put all it's effort into growing roots. This seems to make sense, however at what point can you take a tree out of a pot and plant it in the ground? Surely when you do this it has unlimited space to grow roots? Should a tree, such as an upright Acer be a certain size before planting in the ground?
