Cultivation methods and precautions of azalea

1. Soil

Rhododendrons prefer loose, fertile, slightly acidic soil with good drainage and air permeability. It does not like heavy, alkaline soil. Therefore, we can mix leaf mold, peat soil and sand in a ratio of five to two to three as the soil for growing it. Before planting or transplanting, you can add a small amount of bone meal to the soil to increase the mineral content in the soil.

2. Temperature

The most suitable temperature for azalea growth is 15-25℃. Try to let it grow within this temperature range in spring or autumn. When the temperature is relatively high in summer, you should pay attention to temperature control, the maximum should not exceed 32℃. When the temperature is relatively low in winter, you should move it indoors in time and keep the temperature above 5℃.

3. Watering

Watering azalea is a technical job. If you water it too much, its roots will easily rot, and if you water it too little, its leaves will dry out. Generally speaking, we only need to keep the potting soil moist in early spring. In late spring and early summer, when it is ready to bloom, its water needs will increase greatly, so you need to water it a little more. In summer, when the temperature is too high, in addition to watering, you should also spray some water on the plants. In autumn, when the weather turns cooler, you need to control the water moderately and let the soil in the pot become slightly dry. After it goes dormant in winter, you should reduce watering.

IV. Precautions

1. Pruning. Rhododendrons grow relatively fast and can easily become very dense, which can result in many of the inner branches and leaves not seeing light and being unable to grow healthily. Therefore, it is necessary to trim it in time, which will not only make it look better, but also make it healthier.

2. Change the pot. The growth of azalea requires the consumption of nutrients in the soil. After one or two years, all the nutrients in the soil will be absorbed by it. At this time, you need to replace it with new soil rich in nutrient content so that it can continue to grow healthily.
