Latest summary of things to note when repotting a Radermachera sinica (China doll tree) - reading this one article is enough

The Radermachera sinica (China doll tree) not only has lush green leaves full of vitality, making it a very suitable auspicious plant for household pot cultivation, but it also has high ornamental value and a good effect in decorating spaces. However, the Radermachera sinica likes a warm, humid growing environment with plenty of light, and has the characteristics of tolerating high temperatures but not cold.

If we want to grow the Radermachera sinica well, we generally need to repot it once every 2 years. By moving it into a pot one size larger, the roots can get more ample space to stretch freely, and at the same time the pot can store more nutrients to promote the plant's growth. But repotting also requires mastering some techniques to ensure it settles into the pot and survives. Below, the editor will share with everyone the precautions for repotting the Radermachera sinica.

1. Carry out trunk truncation to reduce water and nutrient consumption

Cutting off the dried-up trunk can play a role in preserving water and nutrients, but to what extent exactly should it be cut, and which position is more suitable? Generally, you can use a small knife to cut open the bark and inspect the dried-up position of the trunk, find the green and withered yellow parts, and then cut off all the dried-up upper part.

And after cutting off the dried-up trunk, we also need to carry out necessary treatment on the wound, for example using paraffin to seal the wound, which can reduce water loss from the wound area and at the same time avoid wound infection.

2. Prepare a mixed potting soil to better help the plant take root and survive

After cutting off the trunk, we then carry out the repotting treatment. But when repotting, be careful to try not to damage the plant's root system. The soil used for potting is also quite important; some gardening friends say to use peat soil. However, the editor thinks that using peat soil alone is not suitable; a mixed soil should be used, and it is recommended to use peat soil, river sand, and garden soil mixed in a certain ratio.

3. Avoid watering thoroughly and use the method of watering a small amount to settle the roots

Replant the trunk-truncated Radermachera sinica into a new pot one size larger. Usually after finishing potting a potted plant, it is necessary to water it thoroughly once in time to settle the roots. However, for the Radermachera sinica, after repotting it is generally enough to water it lightly. Exactly do not water it thoroughly, and the water temperature should also be kept as consistent as possible with room temperature, with no major temperature difference, otherwise it will affect the vitality of the plant's root system.

After completing the first light watering after potting (note, not thorough watering), do not water it again in the short term. Because the Radermachera sinica that has just been repotted has very poor root vitality, and has not yet grown new roots, so the root's ability to absorb is limited. If too much water is given at this time, it is easy to inhibit the roots' respiration, thus causing death by suffocation.

4. Place it in a warm place that can receive scattered light to recover

Next, what we need to do is place the repotted Radermachera sinica in a warm place that can receive scattered light to recover. Generally, just keep the temperature above 20°C, because the Radermachera sinica relatively likes a warm growing environment, so providing scattered light for it at this time is more suitable, which is more conducive to the formation of the trunk's transpiration pull.

5. Water in time to avoid the potting soil becoming too dry and affecting survival

For the second watering, it is usually necessary to wait a period until the potting soil becomes dry and cracks before carrying it out. And this watering cannot be done with a small amount of water like the first watering; it must be watered thoroughly until water flows out from the drainage hole at the bottom of the pot. In this way, it can be ensured that the Radermachera sinica can smoothly survive after repotting and maintain good growth.
