What fertilizer is best for azaleas? Fertilizer selection and application methods
What fertilizer is best for azaleas? Please give guidance. Azaleas are fertilizer-loving plants. In addition to the main nutrients nitrogen, phosphorus and potassium, they also need trace elements such as boron, copper, molybdenum and zinc. For azaleas, fertilizers with mild strength and long-lasting effect are suitable. For home azalea growing, ox horn, ram horn and animal hoof pieces can be used; these fertilizers contain 12%-15% nitrogen and 0.2%-8% phosphorus, and also contain a small amount of potassium and trace elements. Thin hoof pieces take effect 1 month after application, while thick hoof and horn pieces show fertilizer effect after 2 months, and the fertility can last 6-8 months. When using them, they can be buried at the edge or bottom of the pot along with repotting or changing pots. Cake fertilizer is also a relatively complete fertilizer in terms of nutrition. The nutrients in cake fertilizer generally contain 2.1%-7.6% nitrogen, 0.54%-3.3% phosphorus and 0.5%-2.7% potassium. Generally speaking, soybean cake and peanut cake contain more nitrogen, while rapeseed cake and cottonseed cake contain more phosphorus. They must be fully fermented before application. Fertilizer made by composting livestock manure and tree leaves can be mixed into the growing medium when repotting.
