color, shape and size, and they take well to pot culture. Azaleas prefer acidic soil. They are basally-dominant plants, unlike other plants used in bonsai which are apically-dominant. Satsuki azaleas are typically cultivated in a specialty soil called Kanuma, which is an incredibly soft, acidic, volcanic soil. This soil accommodates the fine, soft, steel wall-like root system that Satsuki azaleas utilize for their water conductivity and nutrient uptake. The best time to repot is after blooming is finished. Repotting can also be done in the late fall, but with care. Flowers take a tremendous amount of energy from the plant so it is best to remove all the flowers, old and new, and the remaining buds, all at the same time; Taking this step will ensure that the following year, the buds will open at the same time.
