Cultivation methods and precautions for Radermachera sinica

Cultivation methods for Radermachera sinica:

1. Soil

Radermachera sinica likes loose, fertile, well-drained soil rich in humus. The soil mix for Radermachera sinica bought directly from outside is generally garden soil + leaf mold + decomposed organic fertilizer + river sand, mixed in a ratio of 5:3:1:1. Nowadays, however, perlite or vermiculite is mostly added to the soil to prevent it from compacting.

2. Water

Radermachera sinica likes a moist environment. During the growing period it not only needs relatively high ambient humidity but also a certain level of soil moisture; however, in spring, during the sprouting of new buds and the growth of new shoots, water should be appropriately controlled to prevent the branches from growing excessively.

In spring, water once every 2-3 days; in summer and autumn when temperatures are higher, water once every 1-2 days; in winter, control water appropriately and water once every 7 days. When watering, pay attention to the weather: choose a sunny day to water and do not water on cloudy days. In addition, in dry and hot seasons, mist the plant every day to maintain a certain humidity, so that the leaves do not turn yellow and drop from water loss.

3. Temperature

Radermachera sinica likes a warm, humid and hot environment, with an optimum growing temperature of 20 to 30°C. When the environment exceeds 30°C, provide appropriate shading, increase misting of the environment and leaf surfaces, or move it to a cool, ventilated place. When the temperature drops below 10°C, move Radermachera sinica into a shed. During overwintering, the indoor temperature should not be lower than 8°C, and at the very lowest must not fall below 5°C, to avoid cold damage or leaf drop.

4. Humidity

Radermachera sinica likes a moist environment, and air humidity is generally kept at 70-80%. A well-ventilated bathroom has great humidity! When placed indoors at home, you can frequently spray the plant with slightly warm clean water to keep the leaves fresh and also increase air humidity.

5. Light

Radermachera sinica likes light and tolerates slight shade; it can grow in either full sun or semi-shade.

Radermachera sinica performs differently at different growth stages. Seedlings tolerate shade relatively well and grow well only with shading; mature plants are best placed by a window indoors with ample light, sometimes in full light and sometimes in diffused light. If Radermachera sinica grows in a dark environment for a long time, it easily drops leaves.

6. Fertilizing

Every April, as temperatures rise, move Radermachera sinica outdoors to grow, and while repotting, add a certain amount of compound fertilizer to the soil; entering the peak growing season, apply decomposed liquid fertilizer once a month, and after the Mid-Autumn Festival apply a phosphorus-potassium fertilizer once to strengthen the plant's cold resistance and ensure it overwinters safely.

Note that when the summer temperature is above 32°C or the winter temperature is below 12°C, fertilizing should be stopped. At such temperatures Radermachera sinica grows slowly and has poor ability to absorb fertilizer, and fertilizer remaining in the potting soil for a long time easily causes fertilizer burn.

Small Radermachera sinica

Small Radermachera sinica and Radermachera sinica are the same plant, but people seem to prefer the mini version. The characteristic of small Radermachera sinica is that its leaves are glossy and bright, as if they were fake, and very beautiful.

The cultivation methods for small Radermachera sinica and large Radermachera sinica are no different; the environment is the same, only the amount of watering and fertilizing should be adjusted according to the size of the pot. Generally speaking, a smaller pot means water evaporates faster, so according to how dry or moist the potting soil is, appropriately shorten the watering interval.

Precautions for growing Radermachera sinica:

1. Avoid cold damage

Summer and winter are the most difficult times for Radermachera sinica - either hot or cold; heat is tolerable, but once it turns cold, the plant is easily frostbitten. So after winter begins, promptly move Radermachera sinica indoors for care and keep the temperature above 10°C. If insulation measures are improper and the temperature stays below 5°C for a long time, cold damage may occur and cause leaf drop.

2. Pests and diseases

Radermachera sinica fears freezing in winter and stuffiness in summer; a stuffy, hot environment easily leads to various pests and diseases. Do prevention work promptly. Once small insects appear on the leaves, immediately spray pesticide and strengthen ventilation. If leaves turn yellow and drop, promptly clean away the yellowed leaves and spray a fungicide.

Radermachera sinica leaves turning yellow

What to do when Radermachera sinica leaves turn yellow?
Radermachera sinica is a sun-loving species that likes light, tolerates partial shade, and has strong drought resistance. The survival rate of planted seedlings is high, and large trees are also relatively easy to transplant successfully and take shape. In care, pay close attention to avoid problems such as yellow leaves. The main reasons for Radermachera sinica leaves turning yellow are as follows:
1. Too high a temperature causes yellow leaves and leaf drop. Many friends do not pay attention to the plant's comfort when placing Radermachera sinica, usually putting it quite close to an air conditioner or computer, and some even let the plant face the computer's air vent directly. This makes the plant very uncomfortable, and it certainly will not grow well and will drop leaves.

Propagation methods for Radermachera sinica

I. Layering propagation method for Radermachera sinica:
Layering propagation can be done between March and April. Below a node on a 2-year-old strong branch or stem, carry out ring-barking, with the bark removal width generally 2 to 3 times the diameter of the layered stem. Below the ring-bark cut, tie a 15 cm x 20  cm plastic film. Using clean, moist peat soil or sandy loam, shape a ball of soil 8 cm to 10 cm in diameter around the ring-bark site. Then wrap the soil ball well with plastic film, leave a water-catching opening at the top, and tie it against the thick main trunk to prevent it from drooping and being broken by wind. By late autumn, after the ring-bark site has grown relatively well-developed roots, cut it away from the parent plant and pot it separately.

Its leaves are dense and verdant, full of vitality, and it can serve as a plant that boosts prosperity, bringing people a message of happiness. Now let us take a look at whether Radermachera sinica blooms!

Does Radermachera sinica bloom?

Radermachera sinica does bloom. In fact, quite a few people who grow it do not know that Radermachera sinica can bloom, because growing it depends greatly on temperature and region, and the likelihood of it blooming when planted in the north is very small. Whether Radermachera sinica blooms depends on strict environmental factors such as temperature, humidity and sunlight, and it must grow for a certain number of years. For example, pay attention to ventilation, pay attention to watering, and expose it to sunlight as much as possible; as long as it is cared for well, it may bloom every year.

The habits of Radermachera sinica

Radermachera sinica likes warm, hot environments, with an optimum growing temperature of 20°C to 30°C. During the intense heat of midsummer, when the ambient temperature reaches above 30°C, provide appropriate shading with a shed, increase misting of the environment and leaf surfaces, or move it to a ventilated, cool place with filtered shade to spend the summer. When late autumn arrives and the ambient temperature drops to around 10°C, promptly move it into a shed or indoors. During overwintering, it is best to maintain a shed temperature of no less than 8°C, and at the very lowest not below 5°C, to avoid cold damage to the leaves or leaf drop.

How to grow Radermachera sinica

1. Temperature: Radermachera sinica likes a warm, humid environment, and temperature is most important. Keeping the daytime temperature between 19°C-21°C and the nighttime temperature between 18°C-20°C is the most suitable growing temperature; too high or too low will affect its growth. In the hot midsummer, try to keep the temperature below 27°C. When the ambient temperature is very high, provide appropriate shading with a shed. Increase environmental humidity, thereby raising leaf-surface humidity. In winter, the temperature must not be below 8°C, and the humidity must not be below 5°C, otherwise it will be frostbitten below this temperature.

2. Humidity: Radermachera sinica prefers moisture in both its soil environment and indoor environment. Keep indoor humidity between 70-80%. In large banquet halls where humidity cannot be controlled, we spray the leaf surfaces once in the morning and once in the evening. If the humidity is too low or it stays in a dry environment for a long time, the leaves will curl and turn yellow, affecting its ornamental value.

3. Light: Radermachera sinica is a plant that likes sunlight and tolerates shade, and light is very important. Radermachera sinica likes to grow in a semi-shaded environment. In the north, we generally keep it indoors, so there is no problem of direct sunlight. It is, however, afraid of being placed in a dark place for a long time, where neither direct light nor diffused light reaches it; over time, it will certainly drop leaves. So in winter it should be placed on a balcony or by a window with ample sunlight to get enough light.

4. Watering: In summer, a potted Radermachera sinica should be watered once every 3 to 4 days, but this also depends on the individual situation. In winter, indoors in the north, Radermachera sinica almost stops growing, and watering should be controlled so that the potting soil simply does not dry out. If you water, water it thoroughly; if you do not water, do not pour a single drop into the pot. This is the principle, please remember it.

5. Pruning: The purpose of growing Radermachera sinica is for ornament and to complement the indoor environment. If the tree shape grows poorly, it will not be attractive, so prune it carefully, generally into a mushroom shape or a rounded mound shape. Cut away some old leaves and yellow leaves.

6. Soil: When Radermachera sinica is growing, soil is equally important. Choose a loose, breathable, well-drained and nutritious soil, usually mixed in the ratio of garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1. Persist in loosening the soil once a month during the growing season to ensure the roots are always in a well-aerated state. If water accumulates in the pot, drain it as soon as possible, and after the potting soil has dried out, repot and change the soil to keep Radermachera sinica growing better.

7. Fertilizing: During the growing period, fertilize Radermachera sinica diligently to ensure vigorous growth. Use compound fertilizer or a nitrogen-phosphorus-potassium 20:10:10 fertilizer or farmyard manure, etc.; in winter, fertilizing can be stopped.

8. Pest and disease prevention: Pests on Radermachera sinica generally include scale insects, mites and aphids. Use jiebisiding, methidathion, manjing, pyridaben, phoxim, omethoate and decis to control the insects. As long as you ventilate and change the air frequently, generally no pests will appear. Radermachera sinica's disease resistance is still quite strong. If the pest infestation is not severe, you may remove them by hand.
