Fertilizing Japanese Maple Bonsai Trees

The use of organic, solid is recommended for Japanese Maple bonsai trees. This soil contains all the micronutrients the plant needs and it takes effect gently and slowly.

Japanese Maple Bonsai Training Techniques

You can trim twigs and shoots all year round, but strong branches should be pruned in autumn or summer in order to avoid excessive bleeding. Cut paste should be applied to any cuts on these trees as fungal diseases can enter through their wounds. Cut back new growth to a pair of leaves or two. To keep twigs thin, you can pinch delicate ramification on mature trees. Once the leaf pair has unfolded, remove the shoot’s tip. Use this method only when necessary, though, as this will weaken the tree long term. 

Every other summer you can prune the tree’s leaves if smaller leaves are desired. Do this by removing all the leaves but leaving the stems. You can also try a more gentle version of leaf pruning, which is partial leaf pruning. In this method, you do not remove all leaves, only remove the biggest ones or remove all the leaves on the strongest parts of your tree. You can use the partial leaf pruning method every year since it is less stressful for the tree.
