Does the Radermachera sinica bloom? Learn about its flowering conditions
The Radermachera sinica is a very good large foliage houseplant. In the north it is generally grown indoors, but most are grown in home and office environments. Its leaves are dense and verdant, full of vitality, and it can serve as a plant that brings prosperity, carrying a message of happiness for people. Now let us take a look at whether the Radermachera sinica blooms!
Does the Radermachera sinica bloom?
The Radermachera sinica does bloom. In fact, many people who grow the Radermachera sinica do not know that it can bloom, because growing the Radermachera sinica is very particular about temperature and region, and the possibility of the Radermachera sinica blooming when grown in the north is very small. Whether the 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 the Radermachera sinica
The Radermachera sinica likes warm and hot environments, and its optimum growth temperature is 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 shed, the environment and leaf surfaces should be sprayed with more water, or it should be moved to a ventilated and cool place with light shade to spend the summer. When late autumn arrives, when the ambient temperature drops to around 10°C, it should be moved into a shed or indoor room in time. During overwintering, it is best to maintain a shed or indoor temperature of no less than 8°C, and it must not be lower than 5°C at the lowest, so as to avoid cold damage to the leaves or leaf drop.
How to grow the Radermachera sinica
1. Temperature: The Radermachera sinica likes a warm and humid environment, and temperature is the most important. Keeping the daytime temperature between 19°C-21°C and the nighttime temperature between 18°C-20°C is the most suitable growth temperature; too high or too low will affect its growth. In the hot midsummer, the temperature should be kept below 27°C as much as possible. When the ambient temperature is very high, shade should be provided appropriately with a shed. Increase the environmental humidity, thereby raising the humidity of the leaf surfaces. In winter, the temperature must not be lower than 8°C, and the humidity must not be less than 5°C, otherwise it will be frostbitten below this temperature.
2. Humidity: The Radermachera sinica prefers humidity in both its soil environment and indoor environment. Indoor humidity should be kept 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 is in a dry environment for a long time, the leaves will curl and turn yellow, affecting its ornamental value.
3. Light: The Radermachera sinica is a plant that likes sunlight and is also shade-tolerant. Light is very important. The Radermachera sinica likes to grow in a semi-shady environment. In the north, we generally keep it indoors, so there is no problem of direct sunlight. What it does fear is being placed in a dark place for a long time, where neither direct light nor scattered light can reach; after a long time, it will definitely drop leaves. Therefore, in winter it should be placed on a balcony or in front of a window with sufficient 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, the Radermachera sinica almost stops growing, and watering should be controlled so that the potting soil is merely not dry. If you water, water it thoroughly; if you do not water, then do not pour a single drop of water into the pot. This is the principle, please everyone remember it.
5. Pruning: The purpose of growing the Radermachera sinica is for ornament and to complement the indoor environment. If the tree shape does not look decent, then it is not beautiful, so it must be pruned carefully, generally pruned into a mushroom shape or a rounded mound shape. Cut away some old leaves and yellow leaves.
6. Soil: When the Radermachera sinica is growing, soil is equally important. Choose a loose, breathable, well-draining and nutritious soil. Usually it is mixed in the ratio of garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1. Insist on loosening the soil once a month during the growing season to ensure that its roots are always in a well-aerated state. 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 to keep the Radermachera sinica growing better.
7. Fertilizing: During the growing period, fertilize the Radermachera sinica diligently to ensure vigorous growth. Compound fertilizer or nitrogen-phosphorus-potassium 20:10:10 or farmyard manure, etc.; in winter, fertilizing can be stopped.
8. Pest and disease prevention: The pests on the Radermachera sinica generally include scale insects, mites and aphids. Use jie bi si, methidathion, man jing, dabamectin, zinc sulfur phosphorus, omethoate and decis to kill the pests. As long as ventilation and air exchange are frequent, generally there will be no pests. The disease resistance of the Radermachera sinica is still quite strong. If the pest problem is not severe, you may remove them by hand.
