Formation and transplantation
Pruning is done immediately after the flowers wither. All inflorescences, weakened and overgrown shoots are removed. Also pinch new processes over the 2nd pair of real leaves.
Young specimens are transplanted every season, mature plants every 3-4 years. Do it by transshipment:
- Carefully remove the bush with an earthen lump.
- Put in a new pot.
- Fill the void with earth. The substrate should be acidic, well permeable to moisture and air.
- Do not over-moisten the soil.

- With a healthy, semi-lignified branch, cut the stalk 5-8 cm. It is preferable to do this in the spring.
- Put for a couple of hours in heteroauxin.
- Plant to a depth of 1.5-2 cm.
- Cover with polyethylene to create greenhouse conditions.
- Clean the shelter daily for ventilation and spraying.
- Keep at +25 ° C.
- After emergence (after 3-5 weeks) transplant.
Azalea is also bred by dividing the bush. This can only be done if the plant is healthy and strong. You need to act with caution so as not to damage the rhizome. After planting, provide enhanced care.
