What are the cultivation methods and precautions for banyan trees?
SummaryLight: Banyan trees are suitable for growing in warm, humid places with ample light; they are drought-tolerant and tolerate partial shade. Watering: Banyan trees easily die from lack of water, so the soil should be kept moist; water as soon as the soil surface turns pale, and water thoroughly; in summer, spray water around the plant. Fertilizing: Bury about 10 granules of compound fertilizer along the edge of the flower pot into the soil each month, then water immediately. Pruning: In the first year, remove buds that are out of position; in the second year, when the branches become woody, shape the tree and tie it appropriately.
I. Banyan Tree Cultivation Methods
1. Light
Banyan is a subtropical plant, suitable for growing in warm, humid, well-ventilated places with ample light. Banyan trees are relatively drought-tolerant and tolerate partial shade. They should be kept in a ventilated, well-lit place and maintained at a certain humidity. If kept in a dark, unventilated environment, the plant easily turns yellow and dries out, which can lead to pests and diseases, or even death.
2. Timely Watering
Potted banyan trees that go without water for a long time easily die from lack of water, so water should be replenished in time according to how dry or wet the potting soil is, keeping the soil moist. Be sure to water thoroughly; you can water until you see water seeping out of the bottom of the pot. For the next watering, wait until the soil surface turns pale and the top layer of soil is dry.
In summer, during hot weather, to increase air humidity, you can spray water around the plant or on the leaves, which also helps lower the temperature.
3. Fertilizing
Banyan trees do not need much fertilizer; simply bury more than 10 granules of compound fertilizer along the edge of the flower pot into the soil each month, then water immediately.
4. Pruning
To give the banyan tree high ornamental value, it should be pruned appropriately. In the first year, simply remove buds that are out of position; wait until the second year, when the branches are thick and woody, then prune and tie appropriately. Generally, pruning once a year is best; vigorously growing ones can be pruned twice. With proper pruning, in about 4 years a good bonsai will have been cultivated.
II. Yellowing Leaves on Banyan Bonsai
1. Water-induced yellowing: If watered excessively, the plant's young leaves become dark yellow and lusterless, and the branches also become thin and yellow-green. The plant should be removed from the pot, placed in a cool, ventilated place to dry, and then repotted.
2. Drought-induced yellowing: If the plant lacks water, the old leaves naturally turn yellow and drop, and the leaf tips dry out, while the new leaves show little change. Therefore, be sure to water in time and water thoroughly.
3. Sunburn-induced yellowing: If a potted banyan tree is exposed to strong direct sunlight for a long time in summer, the leaves easily develop yellow spots, and the leaf edges and tips dry out. It should be shaded appropriately or moved to a cool place for care.
4. Lack of light: If the plant is kept in a dark environment for a long time, it cannot carry out photosynthesis and cannot form chlorophyll, causing the leaves to gradually turn yellow and drop. Therefore, it must be kept in a place with ample sunlight.
5. Fertilizer-induced yellowing: If too much fertilizer or fertilizer that is too concentrated is applied, the plant easily turns yellow. Therefore, stop fertilizing and pour in a large amount of water to dilute the fertilizer and reduce the harm.
6. Lack of fertilizer: If the plant lacks nutrients, the leaf color becomes pale and yellowish, and the old leaves slowly turn from green to yellow. Therefore, be sure to check the potting soil in time and apply light fertilizer frequently as part of routine care.
