The trunk of your Ficus microcarpa is always dry, mainly because the light in the environment is not good enough. Banyan trees need sufficient light conditions to grow well and good ventilation, and they are easy to dry up and fall leaves in a cool environment.
In addition, if the branches are harmed by scale insects, it is easy to produce litter. There is also a common pest, thrips, which needs to be controlled in time.
Banyan trees are suitable for potted plants. It is often used to decorate the halls and entrances of hotels and public places, and is also suitable for family living rooms and window sills.
I like a warm and humid environment, need plenty of sunshine, be cold-resistant and shade-tolerant, have fertile soil and good drainage, and have a temperature of not less than 5℃ in winter.
Because of the rapid growth of banyan trees, pots should be changed every spring to increase fertile soil and trim and shape. Water more in summer when it is hot, and water the leaves frequently. Fertilize every half month during the growth period 1 time. Avoid strong light.
