How to grow a Radermachera sinica and precautions: what to do if the Radermachera sinica drops its leaves

The Radermachera sinica symbolizes happiness and peace, with luxuriant branches and leaves, and small emerald-green leaves, making it highly ornamental. So how do you grow a Radermachera sinica? Let's learn about the growing methods and precautions for the Radermachera sinica, as well as what everyone cares about most: what to do if the Radermachera sinica drops its leaves.

Growing methods for the Radermachera sinica

1. Temperature

The Radermachera sinica likes warm and hot environments. The suitable growing temperature is 20°C-21°C during the day and 18°C-19°C at night. In midsummer, try to keep the temperature below 27°C. When the ambient temperature is very high, provide appropriate shade with a canopy, and increase the humidity of the environment and leaf surfaces. During overwintering, it is best to maintain a greenhouse temperature of no less than 8°C, and the minimum must not be lower than 5°C, so as to avoid frost damage.

2. Light

The Radermachera sinica is a light-loving plant, and it can also tolerate slight shade. Either full sun or partial shade is acceptable. However, in summer do not let sunlight shine directly on it; provide shade with a canopy. When potted plants are placed indoors, it is best to place them by a window or on a balcony with sufficient light to receive partial shade or scattered light. If it is placed in a dim indoor area for a long time, it is prone to leaf drop. For home pot cultivation, during overwintering it can be placed in a higher position in front of a window or balcony so that it receives more light.

3. Humidity

The Radermachera sinica likes relatively moist soil and a moist growing environment. Air humidity should generally be maintained between 70-80%, and should not exceed 85% at most. If kept at home, you can often spray the plant with slightly warm clean water to maintain its fresh appearance and also increase the ambient humidity.

4. Growing medium

Choose a culture soil that is loose, fertile, well-drained and air-permeable, and rich in organic matter. Usually mix 5 parts garden soil, 3 parts leaf mold, 1 part decomposed organic fertilizer, and 1 part river sand. During the growing season, loosen the soil once a month to ensure the root area is always in a well-aerated state. If water accumulates in the pot, drain it as soon as possible, and repot and change the soil after the potting soil has dried out. Generally, for small and medium-sized plants grown as home potted plants, repot once a year in early April when they are moved out, to meet their soil fertility needs for a full year of growth.

5. Fertilizer

The Radermachera sinica grows relatively quickly and needs sufficient nutrients to ensure vigorous growth, so during the growing period it needs frequent fertilizing. Generally, a mixed fertilizer with an NPK ratio of 20-10-10 or 15-15-15 is sufficient. Diluted weak fertilizer water can also be used instead of clean water to water the potting soil.

Precautions for growing the Radermachera sinica

The Radermachera sinica likes warm and hot environments, and the suitable growing temperature is 20°C to 30°C. During the intense heat of midsummer, when the ambient temperature reaches above 30°C, provide appropriate shade with a canopy, increase misting of the environment and leaf surfaces, or move it to a ventilated, cool place with dappled shade to spend the summer. When late autumn arrives, when the ambient temperature drops to around 10°C, move it indoors into a greenhouse in time. During overwintering, it is best to maintain a greenhouse temperature of no less than 8°C, and the minimum must not be lower than 5°C, so as to avoid cold damage to the leaves or leaf drop. For home pot cultivation, it can be moved indoors where there is air conditioning or an electric heater, ensuring the room temperature is not lower than 8°C so that it can pass the winter safely.

What to do if the Radermachera sinica drops its leaves

There are many reasons for leaf drop in the Radermachera sinica. You need to find out the cause of leaf drop and deal with it accordingly. The following are the causes of leaf drop in the Radermachera sinica and the solutions:

When late autumn arrives, when the ambient temperature drops to around 10°C, move it indoors into a greenhouse in time.

2. Light reasons:The Radermachera sinica is a light-loving plant, and it can also tolerate slight shade. Either full sun or partial shade is acceptable. Its seedlings are relatively shade-tolerant, and in summer shade should be provided with a canopy. For potted plants, during indoor display they should be placed by a window with sufficient light or indoors. If it is placed in a dim indoor area for a long time, it is prone to leaf drop. For home pot cultivation, during overwintering it can be placed in a higher position in front of a window or balcony so that it receives more light.

3. Water reasons:During cultivation, the soil and display environment should be relatively moist. During the seedling stage, the seedbed must be kept moist. In hot seasons, sufficient water must be supplied, and in hot seasons spray the plant 2 to 3 times a day. In summer and autumn, place the plant outdoors for care. In winter, place the plant indoors; the plant enters dormancy, so do not water too much to avoid root rot.

4. Soil reasons:For potted Radermachera sinica, choose a culture soil that is loose, fertile, well-drained and air-permeable, and rich in organic matter. Usually mix garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1. During the growing season, loosen the soil once a month to ensure the root area is always in a well-aerated state. Generally, for small and medium-sized plants grown as home potted plants, repot once a year in early April when they are moved out, to meet their soil fertility needs for a full year of growth.

5. Fertilizer reasons:For potted Radermachera sinica, in addition to adding an appropriate amount of decomposed cake fertilizer and 3% compound fertilizer to the culture soil, topdressing should also be given continuously. During the growing season, apply a quick-acting liquid fertilizer once a month, usually decomposed cake fertilizer water. For a small number of home potted plants, or for large potted plants displayed in public places for a long time, a small amount of slow-release compound fertilizer granules can be buried regularly, or a mixed solution of 0.2% urea plus 0.1% potassium dihydrogen phosphate can be applied.
