How to change the pot and soil of azalea (do you need to remove the old soil when changing the soil of azalea)

Reduce root damage

The roots of azalea are delicate. If damaged, it may cause partial necrosis or rot of the roots, leading to yellowing and falling leaves, and even falling buds and flowers. In severe cases, it may lead to the death of the entire plant.

Therefore, when changing the soil for azalea, you must be careful to avoid damage to its root system .

Especially when removing the plant from the pot, you should be meticulous and control the water 5 to 7 days in advance. When the soil in the pot is slightly dry and slightly moist, gently tap the pot wall with your palm to separate the soil from the pot wall, and then remove the soil from the pot.

Preserve the soil that protects your heart

After removing the azalea from the pot, remember not to knock off all the old soil. Instead, you should retain about 2/3 of the protective soil. This will help its roots to restore the ability to absorb water and nutrients and shorten the time it takes to acclimate.

At the same time, the old soil with high salt and alkalinity on the surface of the soil should be removed, and new soil rich in organic matter should be added.

The purpose of doing this is, on the one hand, to provide the azalea with fertile new soil, and on the other hand to avoid damage to the root system, which is conducive to the rapid growth of the azalea in the pot .

Treatment after root injury

If the azalea is accidentally rooted, if the damage is not serious, you can water it appropriately or spray the leaves with water, and place it in a cool and ventilated place for a period of time. It will recover through the seedling acclimatization period and will slowly adapt to the pot.

There are also newly transplanted azalea potted plants, because of root damage, need to be taken care of for a period of time, and they can recover after the roots grow well. However, for azaleas with more serious root damage, there is no way to save them.

In short, it is best to repot and change the soil for azalea in spring. When replacing the old soil, you should pay attention to retaining the protective soil to increase the growth function of the azalea root system and avoid losing too much old soil, which will damage some of the capillary roots and affect its later nutrient absorption and growth .
