Bonsai Edit

Satsuki Azaleas are popular bonsai plants for many reasons. It can take a hard pruning, the flowers are amazing, and they can be developed fast. Since azaleas prefer to be slightly acidic, a popular soil to grow them in is kanuma.

Repotting: is a big stress to any tree, and bare rooting is the biggest stress to a tree. When repotting Satsuki Azaleas, it is better to do it at a certain time. Repotting in early to middle spring is best. Some people say that you should repot after flowering, but this is not the case. Flowering is the second biggest stress to a satsuki. So repotting and flowering in the same year is not a healthy thing to do for a tree. That is why when repotting, do not let the satsuki flower that year. Kanuma is a recommend soil for satsukis. Also, it is popular to put yamagoki moss on top of the soil to keep them moist. This will benefit the many feeder roots of the tree.
