1. Appropriate time

Before fertilization, it is necessary to select an appropriate fertilization time. When it is in the growth period, because it takes a long time, although it can tolerate a little barren and drought in the whole period, it cannot be lack of nutrients, otherwise it will slow the development of plants and reduce the amount of flowering. In addition, when it is still a young seedling, it needs to apply base fertilizer in the soil and topdressing appropriately before flowering, and then there is no need to apply fertilizer after flowering

2. Select appropriate fertilizer

When fertilizing it, we must choose the appropriate fertilizer. In addition, when fertilizing it, you can choose special fertilizer for flowers, which is not only convenient to use, but also give it more nutrients and make the leaf color beautiful

3. Master fertilization skills

During fertilization, fertilization should be based on the size of each plant. When fertilizing, do not apply too much fertilizer at one time or use fertilizer with too high concentration, otherwise its roots will be burned and the plant will die in serious cases. Therefore, the fertilizer should be thinner. For 1-2-year-old seedlings, phosphorus and potassium fertilizer can be used more, so that the seedlings can grow strong. For seedlings growing for more than 3 years, more nitrogen and phosphorus fertilizer should be applied, not more potassium fertilizer, otherwise it will affect the yield of essential oil. In addition, when applied, it can be combined with watering, and its effect will be better
