Japanese Maples can thrive in pots if planted right and cared for. You’ll need a large pot, a sunny spot and good soul. The pot needs to be twice the size of the tree’s root system and has good drainage holes. Use a good quality potting soil and wait until the spring to fertilize. Keep an eye on the roots when your tree grows and prune the roots when necessary.
Key Takeaways:
- To start growing a potted Japanese maple, you need a large container, good potting soil and a partially sunny location for it.
- Pick dwarf or semi-dwarf species, which generally grow slower in pots and develop smaller root systems. At less than 10 feet tall, you won’t have to do annual pruning.
- Plant your tree in a container that is about twice the size of the tree’s root system. It is imperative that the pot has one or more drainage holes. Keep the soil moist but not wet.
“The first step toward having a container grown Japanese maple is to determine a variety that would work well in your area.”
