If you want the small banyan tree to grow better, you naturally need fertilizer. Fertilization must be reasonable during the growth of small banyan trees. The fertilizer is mainly nitrogen, phosphorus and potassium compound fertilizer, and the content of nitrogen fertilizer should not be too high, so as to avoid long branches and leaves and no roots. With sufficient fertility, the roots of small banyan trees will grow faster.

2. Replace flowerpots regularly.

The space of flowerpots is limited, and the roots of small banyan trees will grow according to the size of flowerpots. If the flowerpot is too small, the roots of the small banyan tree will not grow much when it is full. Therefore, it is necessary to change a bigger flowerpot to promote the growth of the root system of the small banyan tree. When changing pots, it is best to trim the roots properly, trim off dead roots, rotten roots and too dense roots, and then replace them with fertile and loose pot soil.

3. Trunk line truncation

If increasing fertility and changing pots don't work, how can small banyan trees thicken their roots? You can try to cut off the trunk, but it will completely destroy the plant, leaving only the root system.

If you want to thicken the root system, you can cut off the trunk continuously, and then cut it off after the roots sprout. The number of times depends on your needs. In addition, keeping roots and exposing the roots of small banyan trees will be more stylish.

Step 3 control the temperature

When maintaining at ordinary times, the small banyan tree can't be frozen, and it must be moved indoors to keep warm in winter.

4. Dressing and shaping

Be sure to ventilate and transmit light in time and strengthen protection. If you have been infected with pests and diseases, you should properly spray special chemicals for prevention and control.
