Yingshanhong cultivated Yingshanhong cultivated Yingshanhong has a large number of flowers, bright colors and strange pile shapes, which is a good material for making flower bonsai, but it is not easy to survive. Combined with many years' practice, this paper talks about several main links of cultivating azalea. 1, the selection of Yingshan red pile requires not only the ancient and the strange, but also the survival. Take more soil and leave more capillary roots. Pile heads without soil and capillary roots are best not. 2. It is observed that the red pile in Yingshan has not grown new roots for several years, but it is still growing and flowering. The reason is that nutrition comes from capillary roots on the original soil ball. Inspired by this, it is the key to ensure the survival of azaleas to prepare suitable soil for planting. It is made of 40% mountain humus, 20% yellow sand and 40% wood sawdust (see figure 1), which is loose, breathable and acidic, and is suitable for planting Yingshanhong pile (see figure 2). Woodworking sawdust, in particular, not only does not burn roots, but also is a good organic fertilizer after decay. 3. Light-controlled Azalea likes a warm and humid climate. Although it is relatively resistant to shade, it has been placed in a place without sunlight, and it cannot be used for photosynthesis and its growth is weak. The sunshine should be controlled at 50-70%, and it is better to plant azaleas in places where there is no sunlight. 4. It's best not to let Yingshanhong pile bloom in the stage of young seedling cultivation and branch storage, because flowering will consume a lot of nutrients and affect the survival of Yingshanhong pile, so be especially careful. Generally, the flowering period should be controlled for more than 3 years, and the flowering period after molding should not be more than 3 years. Free-range branches will be removed at the early stage of bud formation, and the retracted branches can be shortened before and after beginning of spring (see Figure 3) to facilitate survival and early formation. 5, thin application of chemical fertilizers The culture soil prepared by the above method does not need fertilization in the current year, and can be applied with thin fertilizer frequently in the next year. It is best to apply cake fertilizer and water, increase the dilution multiple, once a month during the growing period, and properly supplement phosphorus and potassium fertilizer in the germination stage to avoid damaging the roots with large fertilizer. 6. Keeping the shape of azalea branches is like crazy growth, and it is not easy to keep the shape. To ensure that bloom is lush and beautiful, we should cut it in spring, pick it in summer and tie it in autumn. That is to say, after flowering in spring, all hair branches can be cut off from the base to facilitate the germination of strong branches; In summer, according to its growth situation, leave 2-3 bud positions for the branches of the current year and then pick them off, so as to pick buds for many times; Because the buds of azaleas are on the branches, it is more appropriate for the leafy branches to climb up and tie them in autumn, and then cut them short after flowering the next year. I copied this, you can learn from it.
