Ficus microcarpa Growing Environment, Potted Cultivation Precautions, and the Medicinal Benefits of Its Aerial Roots

Ficus microcarpa, also known as small-leaved fig, evergreen tree, etc., reaches 15-25 m in height, with a flowering period from May to June. Here we take a look at where Ficus microcarpa grows, what precautions are needed for potted cultivation, and what medicinal benefits its aerial roots have?

1. Where does Ficus microcarpa grow?

Ficus microcarpa has strong adaptability and prefers loose, fertile acidic soil. It can also grow in poor sandy soil, but its leaves turn yellow in alkaline soil. It is not drought-tolerant and is relatively tolerant of wet conditions; short periods of waterlogging will not cause root rot. It grows poorly in dry climatic conditions, but in humid air it can develop aerial roots, greatly enhancing its ornamental value. It prefers sunny, warm and humid climates and is not cold-tolerant; outside of South China it is mostly grown as a potted plant. It is not demanding about soil and can grow in both slightly acidic and slightly alkaline soil, but fears scorching sun exposure.

It is distributed in China, Sri Lanka, India, Myanmar, Thailand, Vietnam, Malaysia, the Philippines, Japan, Papua New Guinea, and Australia, extending to the Caroline Islands.

2. What precautions are needed for potted cultivation?

1. Watering

When planting a Ficus microcarpa bonsai, simply cover the roots with cultivation soil; for cuttings, a depth of about 3 cun is suitable. After watering to settle the roots, place it in a cool, sheltered spot for care; for ground-planted specimens, use a cover to provide shade. Watering can be adjusted according to weather conditions, keeping the cultivation soil moist but not waterlogged; excessive waterlogging easily causes the roots to turn black and necrotic. If a established Ficus microcarpa is waterlogged for a long time, it easily produces only roots without growing branches and trunks. During the dog days of summer, if not watered for two or three days, the tree will not die, but once watered, the leaves will wilt and drop, affecting growth. Therefore, water management should follow the principle of "dry-wet alternation." Improper watering causes great harm to Ficus microcarpa. Feel the condition of the potting soil by hand and follow the principle of "dry-wet alternation." Do not water frequently, but water thoroughly when you do. Overwatering can cause root rot and leaf drop. Ficus microcarpa is more difficult to care for in northern regions; households should spray water on the leaves more often to increase the humidity around the air.

2. Light

Ficus microcarpa bonsai should generally be placed in a well-ventilated, well-lit location with a certain amount of spatial humidity. Insufficient sunlight, poor ventilation, and lack of spatial humidity can cause the plant to turn yellow and dry out, leading to pest and disease problems and eventually death. The suitable growing temperature for Ficus microcarpa should not vary too much between day and night (a difference of 10 degrees) as this easily causes leaf drop and death. Usually, place it in a well-lit location, and in summer take care to provide appropriate shade.

3. Soil

The cultivation soil for Ficus microcarpa bonsai is generally required to be loose, breathable, and slightly acidic, such as black stone powder mud, river sand, construction stone powder, coal cinder, etc., and these cultivation soils are relatively easy to obtain. Use loose, well-draining leaf mold as the cultivation soil, usually in the ratio of garden soil : humus soil : sand at 2:2:1. It is best to place moss on top of the bonsai matching the size of the pot; this is both aesthetically pleasing and helps with drainage and aeration.

3. What medicinal benefits do the aerial roots of Ficus microcarpa have?

Ficus microcarpa aerial roots (Ficus root tendrils): bitter, astringent, neutral. They dispel wind and clear heat, invigorate blood and detoxify. Used for colds, whooping cough, incomplete measles eruption, tonsillitis, and traumatic injuries.

Stump bonsai can be used to decorate home living rooms, offices, and tea rooms, and can also be displayed year-round in public places without the need for meticulous management and care. Ficus microcarpa can be made into bonsai to decorate courtyards and bedrooms. It can also be used as a specimen tree for ornamental purposes.
