The growing medium for Hairy Azalea can be mixed in a ratio of 4:2:1:1:1 using humus soil, old potting soil, sandy soil, charred soil, and sawdust, and a small amount of cake fertilizer can be added to enhance the soil's nutrient content.
2. Light
Hairy Azalea loves light and requires ample sunlight. However, the plant should not be exposed to strong sunlight for too long, and it is best to care for it in semi-shaded environments like balconies or windowsills.
3. Temperature
Hairy Azalea prefers a cool and comfortable growing environment, with the optimal temperature range for its growth being 15°C to 28°C. It can survive in temperatures as low as -8°C but is not heat-tolerant. Care should be taken to cool it down when temperatures are too high.
4. Watering
Watering for Hairy Azalea should be done when the soil is dry to slightly moist. It is important to observe the dryness of the growing medium, and water when it is dry. In the summer, when temperatures are high, it can be watered once a day, while in winter, the watering frequency should be reduced to once every 4 to 5 days.
5. Fertilizing
Fertilizing Hairy Azalea should be done in small amounts multiple times, taking care not to over-fertilize or use a high concentration of fertilizer, which can have adverse effects. Generally, during the growing season, it should be fertilized once every two weeks, with an additional application before and after flowering. No fertilizing is needed when winter arrives.
6. Pruning
During the growing season, it is important to pinch back and prune Hairy Azalea to promote its growth. When pruning, remove weak and dead branches to ensure the supply of nutrients to the main branches and leaves.
7. Pest and Disease Control
Hairy Azalea is susceptible to pest and disease threats, so timely prevention and control are necessary.
