Placing a Bonsai tree so it can grow properly can be tricky. Fortunately, oak trees make this very easy!
While they are growing, oak trees generally prefer full sun in an airy area. During winter months, it is best to keep your oak indoors. You can put them in a greenhouse, too, as long as you can keep it free from frost.
Pruning Your Oak Bonsai Tree
The best time to do the most pruning on your oak Bonsai tree is in the spring before the tree begins to bloom. You can remove the biggest leaves on your oak Bonsai tree every so often. But if you remove too many leaves, this can weaken the tree, so be careful!
