With the growth of Rhododendron, the plant will grow, the root system will become developed, the growth will be limited, and the soil fertility will also decline. So. Rhododendron is generally in every 2 - 3 years, we have to change basin once
When the Rhododendron is changing pots, it is necessary to select the right size flowerpot according to the growth of the plant, and sterilize the flowerpot before using. First of all, drainage layer should be done in the basin.
Take the azalea that needs to be replaced out of the pot, take out the plant slowly from the pot, remove one third of the old soil, and trim the old root. Then put the Rhododendron in the new pot again, straighten the plant, slowly extend the root system, and slowly add the soil. When adding the soil, it can be compacted by hand. Pay attention that the soil should not be added too high, and keep it about 3cm lower than the basin mouth.
After the azalea is put into the basin, it needs to be watered thoroughly first. You can use the method of soaking the basin to water it. Let the whole basin of azalea be immersed in the water for more than ten minutes, and then it can be taken out after the soil is completely wet. After changing basin, you can put Rhododendron in the half shade for half a month or so, strengthen water spray, etc. slow seedlings can be maintained normally.
In the cultivation of Rhododendron, found the following situation, you can change basin.
At the bottom of the flowerpot there are roots leaking; when watering, there is water in the basin and foam in the water; this is the soil hardening; the plant grows too fast; the soil is uplifted upward; when the ramets are needed to reproduce.
