1. The suitable time for pruning Dracaena is spring and summer, and the specific time is May-July. At this time, it grows fastest, and new branches and leaves can sprout quickly after pruning.

2. When pruning the dragon's blood tree, it should be decided according to the stage. If it is trimmed during plastic surgery, the bottom leaves should be cut off and the top leaves should be trimmed. When growing, prune the branches with relatively weak growth and leave thick branches. This will make its nutrition more concentrated and will not be wasted on other branches. In addition, the dragon's blood tree should be flattened at a certain height, and new leaves should be left at the top of the main stem, and the lateral buds on the main stem must be removed at any time.
