The Japanese holly is ideal as a bonsai, ideally even as an outdoor bonsai. Rain and wind then harden their leaves giving them enough energy to grow a proper trunk. This keeps it healthy and resistant to diseases and pests.
The Japanese holly grows very well as a bonsai
How do I grow a Japanese holly bonsai?
Since the Japanese holly is quite slow growing, it is very easy to shape into different shapes, whether upright, cloud-shaped or spherical, depending on your preference. Note, however, that the red or black berries of this plant are poisonous and should be kept out of the reach of children if possible.
During the summer, Japanese holly should be pruned about every six to eight weeks with well-sharpened tools. When repotting, also prune the roots to give your holly a balanced appearance.
During the winter months you can wire the holly into the shape you want. As soon as the branches and trunk begin to grow thick again in May, remove the wire so that it does not leave unsightly marks on the bark.
How do I care for the Japanese holly as a bonsai?
As a thirsty plant, the Japanese holly should be watered regularly. If the fine roots dry out, they die off quickly. Therefore, avoid letting the soil dry out, this is especially important in the warm season. Since the Japanese holly is an evergreen plant, it needs to be watered well even in winter.
If you forget to water, immersing the plant pot in water or rinsing off the plant can help. It is best to use rainwater for this so your holly does not get lime stains on the leaves. You should fertilize the Japanese holly from spring to autumn with organic fertilizer or a special bonsai fertilizer.
The essentials in brief:
- best grown as an outdoor bonsai
