How to Care for Chinese Pepper Bonsai Tree


The Chinese Pepper is a resistant plant that can withstand temperatures as low as -4°C. However, they dislike freezing their roots, so you should shelter them in cold areas. They make excellent interior bonsai in most cooler climates.

You may maintain the Chinese Pepper outdoors in a warm environment. You can put it in a wind-sheltered open location or semi-shade in a warmer region from May to September. From autumn through springtime, the plant needs a stable, bright environment between 16 and 23 degrees Celsius.


The Chinese Pepper requires a huge amount of water in the heat, but it cannot handle stagnated dampness. You should hydrate the Chinese Pepper plant regularly when the top soil settles down if the compost is well-draining. It must be maintained more carefully in the wintertime, but if the plant is situated near a heat source, make sure the rootball doesn’t somehow dry up.

Water is required, especially before cultivation. Drought may be devastating to Chinese Pepper. Use a moist dish and spray as much as necessary when growing inside. Limit watering to avoid waterlogging the container if the average growth slows down throughout the wintertime.


From springtime until fall, apply liquid fertilizer for two weeks and once a month in the wintertime, according to the dosage instructions. You may also apply granular organic fertilizer in the summertime. Use each month or two or until the granules have disintegrated when using a pelletized form.


Humidity is necessary for foliage to stay fresh and nutritious. The atmosphere is rather humid indoors when your shrub is inside. Throughout the day, mists frequently. Stop placing your Bonsai beside an airflow or outlet since this may cause the leaves to dry up.

A moisture plate is an excellent technique to boost humidity levels. Water is in the bottom of these narrow pans loaded with tiny pebbles. Be sure the water level in the Bonsai planter doesn’t reach the bottom. As the water is gone, the atmosphere becomes a lighter texture.

Pruning and Wiring

Once four leaflets have formed, new branches are trimmed down to two sets. Do not entirely deplete the Chinese Pepper. You may do wiring at any time of year. Pruning, including guy-wires, enables the Chinese Pepper to establish its ideal tree form.

Because the Chinese Pepper is a perennial plant, it thrives from frequent trimming, particularly between springtime and mid-summer. If you would like blossoms and produce, don’t prune afterward. You should prune stalks back to three active nodes or auxiliary branches. Because twigs can be fragile, snipping and sprouting instead of wire is the best way to shape them. If wiring is necessary, do so in the autumn, taking measures to protect the base.


Because Chinese pepper plants have deep roots, you must repot them every two years. Choose a thick, natural bonsai solution that drains well. Employ equal portions of leaf mold or peel, soil, and coarse grit. Additionally, you can use a 2-to-1 mixture of Akadama and pumice. Mature plants should be repotted every three years with root clipping in springtime.


Seeds and clippings can be used to grow the Chinese Pepper tree, as well as air-layering.

Bonsai Pot

Pepper tree trees grow best in glazed bonsai pots. Because the pepper plant is not a tough external bonsai, you should not use a frost-resistant, handcrafted bonsai container. Interior bonsai may easily be grown in inexpensive bonsai containers. It is important to note that the craftsmanship of these low-cost planters cannot compete with the excellence of handcrafted bonsai planters.

Insects, Pests, and Diseases

Spider mites might appear if the plant is kept indoors or in a garden during the wintertime. The Chinese Pepper plant is less susceptible to scaling.
