Azaleas have lush branches and leaves and brilliant flowers. In cultivation and management, the following eight points must be noted: 1. Carefully choose flower pots. For potted azaleas, clay pots are most suitable, especially for small seedlings, because clay pots absorb water and breathe, which is beneficial to root growth and development. For large seedlings over 3 years old, purple clay pots can also be used, but more broken tiles and coarse-grained potting soil should be placed at the bottom of the pot to facilitate air permeability and drainage, otherwise root rot is likely. 2. Skillfully choose potting soil. Azaleas like loose, fertile, well-drained, slightly acidic mountain soil or potting soil with a pH value between 5.5 and 6.5.

Eight key points to grasp firmly in autumn nursery management
1. Apply fertilizer in the right amount. There are usually two ways to apply topdressing. ① Underground topdressing. Generally, quick-acting fertilizers such as urea are sufficient.

Under normal circumstances, apply 15-20 kg of urea per mu, then apply again after 15 days, and 2-3 applications are enough. ② Foliar topdressing. In autumn, combine it with pesticide spraying and spray 0.2% urea plus 0.3% potassium dihydrogen phosphate solution. For broadleaf tree species, it is best not to fertilize again after the Beginning of Autumn
