Boxwood bonsai

The boxwood is a shrub that can reach in its natural state up to 6 metres in height. It has a very slow growth and can live up to 500 years. It has a very attractive, yellowish brown rough bark. Elongated and bright green leaves. It is a perennial species. It is an outdoor plant that supports moderate cold well.

Scientific name: Buxus harlandii Common name: Chinese boj Family: Buxaceae Origin: China, Japan, Korea, Taiwan Languages: Harland Box The boxis a shrubor small evergreen tree. Usually used in gardeningto form hedges and also very often to create topiary art with plants. The reason is that it supports well the pruning and trimmingin addition to having small leaves that reduce the effect of the cut and can show a totally compact aspect. This boxwoodvariety has quite hard green leaves, with a shape clearly more elongated than those of most other boxwood species. The trunk of yellowish colour and a wood of great hardness that has been used to make many elements. This plant can be placed in the interior, but is always better located outside. If temperatures are going to drop below 0º C it is better to keep it in a protected area. For the plant it is of interest to this plant to spend the winter season at low temperatures as it will protect it from certain diseases and will favour its future sprouting. If the temperature is above 30ºC we must vaporize/spray the plant and reduce the fertilizer dosis. This species of box supports full sun although in the middle of summer it may be good for the tree to be placed in parcial shade, at least in peak times, when the sun is stronger. Irrigation: The box likes the humidity. However, as with most bonsai trees, we should not let it be waterlogged as this could rot the roots. In general it is important to monitor the condition of the substrate often to see how it is affected by the environment where we keep our tree. Between each irrigation we must let the substrate dry up a little, not completely just to make sure that there is not too much humidity. Fertilizing: This box variety supports a fertilizer a little less strong than other boxwood species. In general it is recommended to fertilize this tree in the season of growth every 20 or 30 days. During this growing season we could also apply a foliar fertilizer to increase the rate of absorption. Transplant: The transplantation is performed every 2 or 3 years in wintertime, between January and February. When we transplant we prune the roots a little and remove the damaged and dead roots. The substrate must have good drainage. A suitable proportion may be 60% mulch, 30% gravel and 10% peat. Pruning and pinching: This type of plant, with a very dense development of foliage, must be aired to get light and air to reach the interior of the tree. In this way we will avoid that the leaves of the interior branches fall off because of lack of light. This action will also promote an important and correct sprouting. We must let the first sprouting of spring develop completely. In late spring, summer and autumn we can prune and pinch to control growth and shape. The pinching will be done when the new branches have 6 to 8 pairs of leaves, leaving 2 pairs when pruning. Diseases: If we maintain the ideal conditions, the possibility that the tree will catch some disease is small. Some diseases that can affect it are mites like the red spider, and the cochineal. It can be affected by some root fungus, usually as a result of excess moisture and lack of sunshine. Wiring: The bark of the box is very beautiful, rough and irregular as it becomes an adult plant. Either way it is quite weak, so the wiring should be done with great care. For this reason it is preferable to shape the young branches that are more flexible and moldable. With any plant, age and size may vary and are therefore approximated. Also, the pot may vary in shape and colour. The photos are indicative and each tree´s style and aesthetic value will vary.
