Before fertilization, the proper fertilization time should be selected. When it is in the growth period, because of its long time, it can tolerate a little barren and drought in the whole period, but it can't be lack of nutrients, otherwise it will slow down the development of plants and reduce the amount of flowering. In addition, when it is still a young seedling, it is necessary to apply base fertilizer in the soil, and apply fertilizer properly before flowering, and then it is not necessary to apply fertilizer after flowering.
When fertilizing it, we must choose suitable fertilizer. In addition, when fertilizing it, you can choose special fertilizer for flowers, which is not only convenient to use, but also can give it more nutrients, so that the leaf color becomes beautiful.
During fertilization, fertilizer should be applied according to the size of each plant. When fertilizing, do not apply too much or use too much fertilizer at one time, or it will burn its root and even cause the plant to die. Therefore, the fertilizer should be thinner. For 1 to 2-year-old seedlings, we can use more phosphorus and potassium fertilizer, 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, or the yield of essential oil will be affected. In addition, when applied, can be combined with watering, its effect will be better
