How to grow a potted banyan tree? A complete guide to care methods
The banyan tree is also known as the small-leaved banyan or fine-leaved banyan. It has a well-developed root system, sturdy branches, thick and deep green leaves, and stays evergreen in shaded seasons. It is a common foliage plant and bonsai species in China. The main purpose of growing a banyan as a potted plant is to use its soft branches and well-developed aerial roots to shape the tree. According to personal preference. The potted plant can be large or small. For a large potted plant, a main trunk 1.5-2 m tall can be cultivated, and by pruning, a few side branches are retained so that the side branches grow concentrated at the top of the main trunk, allowing aerial roots to hang down from the canopy, and the thick aerial roots are coiled around the main trunk, like a jade pillar with a coiled dragon; the thinner aerial roots are allowed to drift naturally, like a fine drizzle.
You can also cultivate a straight main trunk and use side branches to tie and shape it in layers. First, insert a thicker wooden stick close to the main trunk as the main pillar. On the wooden stick, use bamboo strips to tie multiple layers of circular frames at a certain spacing, and fix the center of the frames onto the wooden stick; the tying positions of the frames should match the growing positions of the side branches, and the spacing should be equal; the diameter of the frames decreases ring by ring from bottom to top, and then the side branches are wound horizontally around each ring of the frames, thereby creating a spiral-style banyan shape.
The banyan tree has strong adaptability. It likes sunlight but is also fairly shade-tolerant, prefers warmth and is slightly afraid of cold, and grows well in a humid environment and loose, fertile soil. When potting, it should be kept with an intact soil ball. A slightly acidic growing medium can be made from peat soil and garden soil plus a small amount of river sand. Generally, repot and change the soil once every 2-3 years. During the growing season, keep the potting soil moist frequently, and especially pay attention to increasing air humidity. In dry air, the leaf edges will scorch, turn yellow, and gradually fall off. Indoors, it should be placed in a ventilated spot with bright scattered light. When placed outdoors, it should be properly shaded in spring and summer, and can receive more sunlight in winter.
In winter, the room temperature should preferably be kept at 5-8°C. Prevent the potting soil from becoming too dry or too wet. Once a week, wash the leaves with lukewarm water close to room temperature to keep the leaves clean and bright green. If the winter room temperature is too high, open the windows for ventilation; otherwise, after being moved outdoors the following spring, it will lose a large number of leaves. If the potting soil is fertile, there is no need for additional fertilizer. During the summer and autumn growing season, a nutrient solution can be sprayed on the leaves to make the branches and leaves dense and emerald green, giving people a sense of beauty.
How should a potted banyan tree be shaped, and how should it be cared for?
In South China, the banyan tree can grow into a large tree more than 30 m tall. The purpose of growing it in a pot is mainly to use its soft branches and well-developed aerial roots to shape the tree. There are two common shaping methods.
(1) Hanging style: first cultivate a main trunk 1.5-2 m tall, let the side branches sprout from the top of the main trunk, and allow the aerial roots to hang down from the canopy.
(2) Spiral style: first cultivate a thick main trunk, then insert a thicker wooden stick close to the main trunk as a support post. On the wooden stick, use bamboo strips to tie multiple layers of circular frames at equal intervals, and fix the center of the frames onto the wooden stick. Then wind the side branches around the frames, thereby creating a spiral-shaped tree.
The banyan tree has strong adaptability, likes sunlight, and is also fairly shade-tolerant. It is not demanding about soil, but it cannot grow in alkaline soil. During care, the potting soil should be kept moist. As long as the fibrous roots do not arch out of the potting soil, try not to repot or change the soil. Pay attention to increasing air humidity.
For potted banyan trees in northern China, proper shade should be provided in spring and summer. After being brought indoors in winter, they should receive slanting sunlight, and they will not freeze as long as the room temperature is not lower than 6°C. If the winter room temperature is too high, a large number of leaves will fall after the weather warms up the following spring. When potting, do not add fertilizer, and there is no need for additional fertilizer, to prevent excessive growth.
How can potted banyan trees grow better?
The banyan tree is an evergreen broad-leaved tree. Its leaves are smooth and leathery, elliptical or obovate, and very attractive. Its branches are soft and flexible, tolerant of pruning, and it has aerial roots, giving it a rather sturdy and ancient appearance. With skillful artistic shaping, it can be enjoyed in all four seasons. Therefore, in the north, the banyan tree is often used as a potted foliage plant or as bonsai material, while in South China it is often used as a street shade tree.
The banyan tree is native to southern China, India, and Malaysia. It is a tropical tree species that likes warmth and is not cold-tolerant. When grown in pots for ornament in the north, it must be moved into a greenhouse for winter care. It likes humid and sunny environments, but is also tolerant of partial shade. It is not demanding about soil and has strong adaptability. Although it likes acidic soil, it can also grow normally in slightly alkaline soil. In the north, potted banyan trees are moved outdoors in May and kept in sunlight or partial shade, then moved into a low-temperature greenhouse in October for overwintering, and can overwinter at a temperature of about 10°C.
Potted banyan trees are mainly grown for their foliage, so during the growing season, more nitrogen fertilizer can be applied to promote leaf growth, and phosphorus and potassium fertilizers should also be applied appropriately. When moving them outdoors in spring, apply more base fertilizer, and afterward apply a decomposed oil cake liquid fertilizer once every half month. During the growing season, water more, and you can also spray water on the leaves to increase air humidity.
The banyan tree is tolerant of pruning. Proper heavy pruning can also make it grow more vigorously. Its branches can be bent and tied at will to make various shapes, such as patterns of the characters "Fu" and "Shou", which are very distinctive and attractive. The roots can also be washed with water to expose them above the ground and increase the ornamental effect.
