Maple Tree's Answer · Hi Shirley-Many Japanese maples will grow in pots for many years. With proper care such as providing correct well draining soil, and repotting every few years during their years of growth they can live their whole life in a container. Once the tree becomes more mature root pruning is needed to keep the plant healthy and allow it to continue to survice in the same size pot for the rest of its life.
It is important to select a Japanese maple cutlivar that will thrive in a container. Some that have a faster growth rate and naturally grow to more mature heights will out grow most easily handled container sizes, this not being true of bonsai growing of maples, but this is another very exacting way of growing. There are many cultivars to select from for container growing. The Red Dragon does very well grown in containers. Two in my maple collection are Red Dragons and now approximately 4 and 6 foot tall and have grown in pots since purchasing them four years ago. I have several Japanese maples that are approximately 10 years old or older that are also doing very well in large 20 - 25 inch pots.
Hope this has helped answer your question.
