Rosemary is not a fertilizer-loving plant, but fertilizer nutrients are still needed, so its fertilization is very particular. Let's take a look at the fertilization methods of rosemary.

1. Fertilizer selection

Before fertilization, it is necessary to choose a good fertilizer, the flower fertilizer rich in phosphorus and potassium is the most suitable, and the fertilizer should be selected according to the growth of the plant. Fertilizers should not contain toxic substances so as not to affect the soil and the growth of plants. Only such fertilizers can be used.

2. Fertilization method

Before fertilizing, we should first root out the weeds and open a shallow trench near the root system, which should not be too close to the root system, lest the fertilizer is too thick and lead to root burning. Reasonably control the amount of fertilizer application according to the growth status of the plant, spread the fertilizer evenly in the shallow ditch, and pour some water after covering the soil, in order to speed up the dissolution of the fertilizer and let it be absorbed as soon as possible. The fertilizer should also be applied once after each harvest, and the main components of the fertilizer this time are nitrogen and phosphorus, so that it can grow again, and it will be better at the next harvest.

3. Points for attention

Fertilizing rosemary is a careful work. In addition to the choice of fertilizer, the amount of fertilizer applied each time is also a difficulty. More or less fertilization can easily cause problems. If the plant is applied less and does not have enough nutrients to make it grow, it will grow slowly and lead to low yield, while more application will lead to plant overgrowth and affect the flowering period.
