Different fertilizers were suitable for different growth stages of azalea: 1. Base fertilizer: When planting or changing pots, compound fertilizer with a balanced ratio of N, P, and K can be added to the soil. Some organic fertilizers can also be applied, such as decomposed cake fertilizer and decomposed animal internal organs. At the same time, some compound fertilizers can be mixed. However, pay attention to the appropriate ratio of fertilizers and avoid thick fertilizers. 2. ** Growth fertilizer (after the autumn and winter flowering period, when new buds and leaves grow)**: Multi-element nutrient solution or multi-element compound fertilizer can be used. You can also use fermented rice washing water (put the first round of thick white rice washing water in a sealed container and expose it to the sun for 1 - 2 months. After fermentation, dilute it with water at a ratio of 1:10. Then add orange peel and lemon peel and expose it to the sun for a week before using it. Water it twice or thrice a month). You can also use azalea special nutrient solution (every 10 days or so, spray the leaves or water the roots in the morning or evening). 3. "Flower promotion fertilizer (before flower bud division and flowering period)": After the spring growth is complete, the flower buds will gradually grow in summer, and during the flower bud emergence stage in autumn, you can use phosphorous and potassium fertilizers, such as potassium monocrescent ortho and Huaduoduo No. 2. In summer, when the growth is slow or not long, once or twice a month, the concentration is low, and it is poured into the pot soil. Continue to use it until the flowers are about to bloom. In addition, before the flowering period, to promote growth, the fertilizer should be mainly organic fertilizer and compound fertilizer. It could also be sprayed with a mixture of rice vinegar and monocrescent potassium hydrogen phosphorus (concentration: 0.001%). 4. Green leaf fertilizer: During the maintenance process, if you find that the new leaves are yellow (the veins are green, and the other parts are yellow and spread), you can use iron sulphuric acid (mixed with water at a concentration of 1:1000, add some vinegar, and water the soil once a month). 5. ** Post-flower fertilizer **: After the flowers wither, they need to replenish nutrients in time. Multi-element fertilizers can be used. When the growth resumed in August and September, the fertilizer was applied once every 15 days, and the fertilizer was stopped after winter.
