Cultivation methods and maintenance matters of old azalea piles

Cultivation method of old azalea pile

1. Root pruning: When digging up old azalea stumps, it is inevitable that the roots will be damaged. When planting, the damaged roots should be picked out first and cut off as soon as possible, because such roots cannot absorb nutrients and water. If left alone, they will slowly rot later, which will easily infect healthy roots. Therefore, root pruning must be carried out before burying the plants in the soil.

2. Prepare potting soil: When planting old azalea stumps, you need to prepare suitable potting soil, ensure that it is breathable and loose. You can mix it with leaf mold, river sand and garden soil. The size of the flowerpot should be determined according to the size of the old stump, and it does not need to be too deep.

3. Pot cultivation: When potting, first add a small amount of soil into the pot, and then put the plant in. Fill the soil and compact it carefully. After potting, water it once in time to help it take root. It must be watered thoroughly and sufficiently, and it must be properly shaded. It is very weak at this time and should not be exposed to the sun. Usually, ventilate more and water frequently to keep it moist. This way, it will resume growth soon.

Pruning old azalea stumps

The old azalea stump can be pruned once after the flowering period. Diseased and insect-infested branches, old and weak branches, dry branches, crossed branches, overlapping branches, and overgrown branches can be pruned away, and the overly long branches can be shortened to make the plant shape beautiful and the branches reasonably distributed, increase the ventilation and light transmission of the plant, and enhance the ornamental value.

Use pots for old azalea stumps

Old azalea stumps are suitable for planting in slightly deeper flowerpots, such as oval, rectangular or round pots. They can also be planted in purple clay or glazed pottery pots.

1. Only two conditions are needed for old stumps to sprout: temperature and water. How to make old stumps sprout new roots can be summarized in a few words: one is to retain, two is to protect, and three is to nourish.

2. The so-called "leaving one" means that when digging up old azalea stumps, you must pay attention to retaining the capillary roots in the middle and upper parts of the old stumps. These capillary roots are extremely precious. As for the main roots of the old stumps, you can use drastic measures for the needs of shaping, but the precious capillary roots must be carefully preserved.

3. The second protection is to protect it carefully. The growth ability of capillary roots is weak. They will dry out if they lose water and die if they dry out. The simplest measure to protect the capillary roots of old piles is to try your best to protect the original soil to which the capillary roots of old piles are attached. You need to be careful when digging. You can also use straw ropes soaked in water to wrap and fix them. Once the straw ropes are dry, you can spray water with fine mist to keep them moist.

4. The three maintenances mentioned here refer to the care for retaining the capillary roots of the old stump after it is potted. First, it cannot be dry, and it cannot be waterlogged. Third, it cannot be heavily fertilized. Fourth, it cannot be exposed to low temperatures. And it cannot be without sunlight. When the capillary roots at the roots of the old roots of the azalea survive and new roots sprout, the old stump can be considered to have been transplanted successfully. This period of time takes about two to three years.

Rhododendrons will enter a dormant stage during low temperatures. The growth of white roots is a good thing, proving that the old stump has survived. At this time, the flower pot cannot be moved and needs to be covered with warm materials to allow the roots to grow fully during the dormant period.

Precautions for the maintenance of old azalea piles

When caring for old azalea bonsai, it should be placed in a dimly lit place and occasionally exposed to the sun. It likes shade and is not resistant to the sun. Strong light must be blocked in time, otherwise it will be sunburned. Water it frequently to keep the soil moist, especially during the growing season. In addition, regular pruning is also important, which can not only maintain a good plant shape, but also promote vigorous growth.
