Many of the local shows are over and trees have been returned to their places. Taking care of bonsai is a time consuming job. It can be considered foolish when we feed trees to keep them healthy and growing - then, spend the rest of the year trimming, pinching, and cutting to keep them small and in shape. Hold off any activity on the soft deciduous growth until it hardens. Keep your eye on the upper portion of these fast growing trees.
Branches tend to thicken and ruin the taper of the design.
Heavy top growth also deprives the bottom branches of light and nourishment. Watch the wires you put on since damage occurs quickly when growth is active. Remove the fast growing water shoots that come out of the root system or the lower trunk area. Cut back on the long internodes and opposite branches. Don't allow the upper branches to take over and shade the lower areas.
