Hello. I just received 6 young japanese maples and one korean maple (Pung Kil). They look really good and healthy. They were sent in 1 gallon containers and are 2 years old. I have a question concerning the best time to replant (now or spring?) in a bigger container since they are young, as well as a question concerning the best potting mix to use for the next few years (does it differ from the mix for older maples?). I intend to keep most of them in containers and not replant in the ground (except one or two). I hope you can find the time to give me some info. I have already planted older maples but would still appreciate your help. Thanks again.
