A Complete Guide to the Key Points of Caring for the Radermachera (China Doll Tree) in Summer

Because of its auspicious name, the Radermachera sinica (China Doll) is deeply loved in homes and office environments. In particular, its lush branches and leaves, with small, emerald-green foliage, make it highly ornamental. Whether placed indoors or outdoors, it draws people's attention, displaying vigorous vitality and also purifying the air. Now let's follow the editor of Boqi Network to see how the Radermachera should be cared for in summer.

Radermachera sinica (China Doll)

1. Temperature:The Radermachera likes warm and hot environments, with an optimum growth temperature of 20°C to 30°C. During the intense heat of midsummer, when the ambient temperature reaches above 30°C, it should be properly shaded with a frame, and spraying of the environment and leaf surfaces should be increased, or it should be moved to a ventilated, cool place with dappled shade to spend the summer.

2. Light:The Radermachera is a light-loving plant, though it can also tolerate slight shade; full sun and semi-shade environments are both acceptable. Its seedlings are relatively shade-tolerant, so in summer a frame should be set up for shading. For potted plants, during indoor display they should be placed by a window with ample light or inside a bright room. If they are left in a dim indoor spot for a long time, leaf drop is likely to occur.

 3. Water:Cultivating the Radermachera requires relatively moist soil and a humid display environment. During the seedling stage, the seedbed should be kept moist, and in the hot, dry season after summer begins, even more attention should be paid to water supply. For potted Radermachera, in order to keep it from growing too tall, watering can be appropriately controlled when new shoots emerge in spring, keeping the potting soil merely relatively moist. For potted plants displayed indoors, besides keeping the potting soil moist, the plant should also be sprayed with water 2 to 3 times a day during hot seasons. For plants kept outdoors for care in summer and autumn, spraying of the plant and the surrounding micro-environment must be strengthened to create a cool, moist and suitable environment for them. In addition, the Radermachera can also be grown hydroponically.

4. Soil:For potted Radermachera, a loose, fertile growing medium that drains and breathes well and is rich in organic matter should be chosen. It is usually mixed from 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. In the plum rain season, for potted plants kept in the open, check the potting soil promptly after each heavy rainfall; if water accumulation is found in the pot, drain it as soon as possible, and after the potting soil dries out, repot and change the soil. Generally, for small and medium plants kept as household potted plants, repotting can be done once a year in early April when they are moved out, to meet their soil fertility requirements for a full year of growth.

5. Fertilizer:For potted Radermachera, besides adding an appropriate amount of decomposed cake fertilizer and 3% multi-element compound fertilizer to the growing medium, 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 households with only a few potted plants, or for large potted plants displayed in public places for long periods, a small amount of multi-element slow-release compound fertilizer granules can be buried periodically, or a mixed solution of 0.2% urea plus 0.1% monopotassium phosphate can be used for watering.

6. Pest and disease control

Leaf spot: In environments with high temperature, high humidity and poor ventilation, the leaves are prone to leaf spot infection. Control method: Whether indoors or outdoors, ventilation and light transmission should be strengthened, and prolonged water retention on leaf surfaces should be avoided, to reduce the possibility of leaf spot occurring. When a small number of diseased leaves are found, promptly remove and burn them, and regularly spray 600 times diluted 50% carbendazim wettable powder, once every half month, for 3 to 4 consecutive times. For household potted plants, for spots appearing on a small number of leaves of individual plants, Daktarin cream ointment can be applied.

Reasons for Leaf Drop in Radermachera and Key Points of Radermachera Care

Because of its good meaning, the Radermachera is loved by many families, and growing this plant is relatively easy. Below, let's take a detailed look at the reasons for leaf drop in Radermachera and the key points of Radermachera care.

1. It may be caused by too much watering and poor ventilation, with the leaf tips turning withered and yellow.

2. The main cause is dry indoor air; spraying clean water on the leaves 2 to 3 times a day can effectively prevent the leaf tips of newly emerging leaves from turning withered and yellow.

3. If growth is normal, there is no problem; sometimes when the environment is changed, some old leaves will fall off.

It may also be caused by the plant being in an environment that is too dark with insufficient light. It can be placed in a relatively bright place, and when the temperature is below 20°C it also needs a full-sun environment. In addition, you may also consider whether too much fertilizer was applied, and whether the organic fertilizer used was fully decomposed.

Key Points of Radermachera Care

1. Temperature: The Radermachera likes warm and hot environments, with an optimum growth temperature of 20°C to 30°C. During the intense heat of midsummer, when the ambient temperature reaches above 30°C, it should be properly shaded with a frame, and spraying of the environment and leaf surfaces should be increased, or it should be moved to a ventilated, cool place with dappled shade to spend the summer. When late autumn arrives and the ambient temperature drops to around 10°C, it should be moved into a shed or room in time. During overwintering, it is best to maintain a shed or room 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 household potted plants, they can be moved indoors to a room with air conditioning or an electric heater, ensuring the room temperature is no lower than 8°C, so they can pass the winter safely.

2. Light: The Radermachera is a light-loving plant, though it can also tolerate slight shade; full sun and semi-shade environments are both acceptable. Its seedlings are relatively shade-tolerant, so in summer a frame should be set up for shading. For potted plants, during indoor display they should be placed by a window with ample light or inside a bright room. If they are left in a dim indoor spot for a long time, leaf drop is likely to occur. For household potted plants, during overwintering they can be placed in a higher position by a window or in front of a balcony, so they receive as much light as possible.

3. Water: Cultivating the Radermachera requires relatively moist soil and a humid display environment. During the seedling stage, the seedbed should be kept moist, and in the hot, dry season after summer begins, even more attention should be paid to water supply. For potted Radermachera, in order to keep it from growing too tall, watering can be appropriately controlled when new shoots emerge in spring, keeping the potting soil merely relatively moist. For potted plants displayed indoors, besides keeping the potting soil moist, the plant should also be sprayed with water 2 to 3 times a day during hot seasons. For plants kept outdoors for care in summer and autumn, spraying of the plant and the surrounding micro-environment must be strengthened to create a cool, moist and suitable environment for them. For plants kept indoors in winter, since the general indoor temperature is below 10°C, the plant enters dormancy, so do not water too much, to avoid water accumulation and root rot. Every 2 to 3 days, around noon on a fine day, spray the plant once with slightly warm clean water, to maintain its fresh appearance and also increase environmental humidity. In addition, the Radermachera can also be grown hydroponically.
