Azalea is an acidic plant, and it is best to use mountain soil containing rotten pine needles to raise piles. It must be a much bigger basin, and the bottom should be filled with about 4 cm of mountain soil. Then put the trimmed pile head in, slowly fill the soil, and do not apply chemical fertilizer. After the basin mouth is quickly filled, it should be moved to a ventilated and sunny place, and the root water should be poured. Then it is necessary to cultivate the soil and bury it in the upper part of the pile, and bury the soil as high as possible to keep the soil moist. When the soil is dry, dig it up and water it, and then bury it to raise piles for a year or two. After complete recovery, excess soil can be removed and liquid fertilizer can be used to promote health. In the meantime, some useless buds were deleted and shaped appropriately. Don't leave too many branches to prevent excessive evaporation and death.
