How to grow a Radermachera sinica? Detailed growing methods and precautions
Radermachera sinica is a very common flowering plant in China. The Radermachera sinica has a very beautiful appearance and very high ornamental value. Its flowering period is also relatively long, with abundant flowers and a faint fragrance. It is found in most companies and households across the country, so if you want to grow Radermachera sinica on a large scale, how should you do it? Are there any precautions? Let's take a look together below!
1. Growing substrate
To grow Radermachera sinica, you first need to prepare the growing substrate. The growing substrate must be loose, rich in nutrients and well drained and irrigated. If conditions permit, you can mix it yourself according to the planting area. Self-mixed substrate is mainly based on garden soil, leaf mold and farmyard manure. When mixing, its pH value should be controlled at around 5.8. When planting, pay attention to loosening the soil and maintaining the permeability of the substrate, so that Radermachera sinica can always live in a good environment.
2. Water management
When planting Radermachera sinica, we must do a good job in water management. The air humidity should be maintained at around 75%. In order to maintain the ornamental value of Radermachera sinica, when it sprouts new shoots in spring, pay attention to controlling the amount of watering and just keep the soil moist. Avoid excessive water causing leggy growth of Radermachera sinica. After entering summer, we should also spray water on the leaves about 3 times a day to lower the temperature. If waterlogging occurs, drain it in time to ensure normal growth of Radermachera sinica.
3. Reasonable fertilization
Radermachera sinica also has a relatively large demand for nutrients during growth, so we should reasonably apply various fertilizers such as nitrogen, phosphorus and potassium. Apply topdressing reasonably during the growing period, especially in the growing season, once a month. We should also reasonably adjust the fertilization ratio according to seasonal changes. For example, when planting in the north and entering the relatively cold winter, around September, appropriately apply topdressing of potassium dihydrogen phosphate about twice. Improve the cold resistance of Radermachera sinica and help it survive the winter safely. If the temperature is not within the range of 12-30 degrees, then topdressing should be stopped.
4. Shaping and pruning
In order to improve the ornamental value of Radermachera sinica, we should also prune it. The first pruning should be carried out before Radermachera sinica buds in spring. The main targets of pruning are old and weak leaves and overly dense and long shoots. Then, trees with many side branches should be properly pinched. If you want to improve the plant shape of Radermachera sinica, then you should also reasonably use growth regulators, such as paclobutrazol, about once a week, and adjust reasonably according to the weather and the growth of Radermachera sinica.
5. Precautions
When planting Radermachera sinica, we should also pay attention to controlling the temperature. The suitable growth temperature for Radermachera sinica is around 25 degrees. In summer, the temperature should be kept no higher than 28 degrees, and attention should be paid to cooling work. In winter, it should not easily be lower than 8 degrees, otherwise frost damage is likely to occur. Then pay attention to controlling light. Radermachera sinica can live in a semi-shady environment, but direct sunlight should not be allowed, otherwise it will cause leaf scorch.
The above is a brief introduction to the growing methods and precautions for Radermachera sinica. Growing Radermachera sinica is not difficult. The main thing is to do a good job in management and pay more attention to some details so that it can be grown better. That is all for today's introduction.
