Large-leaf azalea is adaptable and easy to care for; small-leaf azalea has bright flowers but requires more care; alpine azalea has many varieties, high ornamental value, but requires special breeding conditions.
Select healthy azalea seedlingsWhen buying azalea seedlings, choose plants with well-developed roots, free from diseases and pests, and with green leaves. Avoid buying plants with yellow leaves and dry branches. During the purchasing process, you can consult the seller or gardener to understand the breeding characteristics and precautions of azalea.
Choose the appropriate breeding containerAzalea has high requirements for soil and containers. You should choose ceramic or plastic pots with good breathability and strong drainage. The size of the container should be determined based on the growth rate of the azalea and the size of the roots, generally twice the height of the plant.
Soil selection and configurationAzalea prefers acidic soil with a pH value between 4.5 and 5.5. Soil configuration can use a mixture of deciduous leaf soil, peat soil, and coarse sand in a certain proportion. The specific ratio is: deciduous leaf soil 50%, peat soil 30%, coarse sand 20%. You can also add some bone meal, superphosphate, etc., to meet the growth needs of azalea.

In the hot summer, you can increase the frequency of watering. In the cold winter, you should reduce the watering frequency. For fertilizing, azalea likes fertilizer but avoids excessive fertilization. During the growing period, apply a compound fertilizer once a month, and apply phosphorus and potassium fertilizer before and after the flowering period to promote bud differentiation.
Lighting and temperatureAzalea prefers a semi-shady environment and avoids direct sunlight. During the breeding process, place the azalea in a place with sufficient scattered light. In terms of temperature, the suitable growth temperature for azalea is between 15-25°C. When the temperature in winter is below 5°C, it should be moved indoors.
Pruning and pest and disease controlDuring the growth of azalea, it is necessary to prune withered branches and diseased branches to maintain ventilation and light for the plant. Regularly inspect the plant and control pests and diseases in a timely manner. Common diseases and pests include aphids, red spiders, and anthracnose.
