This winter is much too warm. Because of the warm temperatures a few bonsai already began to grow. Some of them are in a need of repotting and so because of the premature growth the repotting was carried outh today.
Today I did some work on my azalea bonsai trees. Every year over winter the older leaves dry out and turn brown. So if you want your bonsai to look good you need to remuve them by hand.
