5 Care Measures For Bonsai Trees To Ensure Growth And Development & Also Maintain ornamental value

Bonsai trees need to be cared for, and Taiwanese friends need to take watering, fertilizing, pruning, repotting, and pest control and other maintenance and management measures to ensure the growth and development of bonsai trees and maintain their deserved ornamental value.

Regardless of whether the tree bonsai in your Taiwan friend’s home was purchased or created by hands-on modelling, they are all precious things that are not easy to obtain and must be carefully maintained.


Watering is a major management task of bonsai trees.

Trees growing in pots and pots are easy to dry due to the limited soil in the pots. If they are not replenished in time, they will die due to a lack of water.

Bonsai trees need to be watered continuously, but too much water should not be too much. Excessive water will cause excessive growth. For example, if the potting soil is too wet for a long time, the roots of the tree will not breathe well, which will easily lead to rotten roots and lead to death.

Therefore, the bonsai must be watered in an appropriate amount, and the principle of “don’t dry it or water it, water it thoroughly”.

The amount of watering should also be determined according to the habit of the tree species. Tree species that prefer dry and wet should be treated differently.

 In addition, different growing seasons have different water requirements.

Generally, water should be watered once in the morning and evening during the high-temperature period in summer. Water can be watered once a day or every other day in spring and autumn. If trees are in a dormant period in winter, watering can be done every few days. Watering is not required during the rainy season or rainy days.

The water holding capacity of pot soil is related to the soil quality. Sandy loam has good water permeability and can be watered frequently; if clay soil has poor water permeability, watering should not be too much.

The dryness and wetness of the potting soil can be judged according to the growth of the leaves (the leaves are wilting and lack of water), the sound of tapping the pot, the colour of the pot soil surface, and whether it is cracked or not.


Wood, Tree, Plant, Ceramics, BonsaiThe nutrient of the potting soil is limited. In order to supply the necessary nutrients for the growth of bonsai trees, attention should be paid to supplementing with appropriate fertilizers.

Generally, bonsai trees grow slowly and do not need to fertilize too much.

Fertilization should be timely and appropriate, and the types of fertilizers and nutrient content should be mastered.

The nutrients required for plant growth are mainly nitrogen (N), phosphorus (P), and potassium (K). Nitrogen fertilizer can promote the growth of branches and leaves, phosphate fertilizer can promote the growth of flowers and fruits, and potassium fertilizer can promote the growth of stems and roots, so choose a fertilizer. It should be determined according to the characteristics and growth of the tree species.

More nitrogen fertilizer should be applied to foliage tree species, more phosphate fertilizer should be applied to flower and fruit tree species, and acid soil-loving tree species such as camellia, rhododendron, lupine, gardenia, etc. should be properly applied with alum fertilizer.


Bonsai trees are still growing. If they are allowed to grow naturally without restraint, they will inevitably affect the shape of the tree and lose its artistic value.

Therefore, timely pruning, long branches and short cuts, dense branches and sparse cuts, pine tree species when the buds just germinate, picking the buds to control the growth of new branches, in order to maintain a graceful tree posture and appropriate proportions.

In order to suppress the high growth of tree bonsai and promote the development of lateral branches, the tender heads of the branches can be removed.

Pick buds

When a tree bonsai grows many adventitious buds on its dry base or on the stem, the buds should be picked at any time so as not to sprout forked branches and affect the appearance of the tree.

Especially tree species such as elm, bird plum, winter season, and June snow are prone to produce adventitious buds, and more attention should be paid to bud picking.

Plucking leaves

The viewing period of foliage tree bonsai is often the new leaf germination period.

For bonsai trees such as elm and ginkgo, you can also enjoy the fresh and tender leaves by picking leaves.

After bonsai trees have grown in pots for many years, their fibrous roots will be densely distributed on the bottom of the pot, which is difficult to penetrate and drain when watering, and fertilizers are not easy to absorb, which will affect the normal growth of the trees. At this time, they should be reported and replaced with soil.

For repotting, you can use the original pot or replace it with a larger pot, depending on the size of the tree.

When repotting, it can be combined with root repair and soil replacement. If the root system is too dense and long, it should be pruned. Soil replacement can improve the aeration and water permeability of the soil and increase soil nutrients, which is beneficial to the healthy growth of bonsai trees and enhances their ornamental effect.
