1. Topdressing conditions

First, make sure the temperature is between 15 and 30, which is more suitable for topdressing. If you are not in this range, you need to be cautious. Nitrogen fertilizer can be added during the growth period, and potassium and phosphorus fertilizer can be added when flowering and fruiting. Topdressing should not be carried out at noon in summer and autumn, but preferably in the evening without sun

2. Topdressing method

First, the soil around it should be excavated, then the fertilizer should be put in, and then the soil should be filled and watered. If it is a water-soluble fertilizer, you can try to dissolve it with water, and then sprinkle it on the leaves or pour it directly with water

3. Topdressing principle

Apply less each time, and you can apply more times

4. Precautions

① It will stop growing during dormancy, and its metabolism and photosynthesis will be relatively poor. If we add fertilizer to it, its dormancy will be broken, and the growth of the plant will be difficult to continue. In this way, the nutrients of the sub plant will also be consumed, and the flowering of the next year will be affected

② When it blooms, you can't apply fertilizer, otherwise the flowers and fruits will fall, and the more serious plants may die

③ Fertilizer can not be applied to newly planted plants, because there are many wounds, which are difficult to heal after stimulation, and the roots will rot

④ It is not allowed to apply fertilizer under its roots, so it will be difficult to absorb and use. It should be applied far away from its roots according to the growth of the plant

⑤ Do not apply concentrated fertilizer or raw fertilizer to it, otherwise it will die and stink

⑥ Pay attention to comprehensive nutrition. If only nitrogen fertilizer is applied to it, its flowering time will be delayed and the flowers will not grow well

⑦ Sick and weak plants cannot be fertilized casually, which is harmful to them. And there is no need to fertilize it at the seed stage, and then fertilize it when real leaves grow
