How to Fertilize Rosemary? Detailed Explanation of Fertilization Methods and Precautions
Rosemary is a shrub in the Lamiaceae family, native to Europe and Africa. During the growing season it gives off a fresh fragrance, and aromatic oil can be extracted from it. It also contains antioxidant substances and has calming, soothing, and mind-refreshing effects, so it is widely used in the pharmaceutical and spice industries. It is a major cash crop in many regions and has high economic value. Rosemary is not a fertilizer-loving plant, but it still needs fertilizer nutrients, so its fertilization is very particular. Let's take a look at the fertilization methods for rosemary below.
1. Fertilizer Selection
Before fertilizing, you must first choose the fertilizer well. It is best to choose a flower fertilizer rich in phosphorus and potassium. The choice of fertilizer should be made according to the plant's growth condition, and it is best to choose one that dissolves quickly and takes effect quickly. The fertilizer must not contain toxic substances, so as not to affect the soil and the plant's growth. Only fertilizer like this can be used.
2. Fertilization Methods
Before fertilizing, first remove all weeds thoroughly, then open a shallow trench near the root system, but not too close to the root system, so as to avoid the fertilizer being too concentrated and burning the roots. Reasonably control the amount of fertilizer according to the plant's growth condition, spread the fertilizer evenly in the shallow trench, then cover it with soil. After covering with soil, you can also water a little to speed up the dissolution of the fertilizer so that it can be absorbed as quickly as possible. After each harvest, fertilizer should also be applied once. The main components of this fertilizer are nitrogen and phosphorus, so that the plant can regrow and the next harvest will be better.
3. Precautions
Fertilizing rosemary is a careful task. In addition to fertilizer selection, the amount applied each time is also a difficult point. Applying too much or too little fertilizer can easily cause problems. If too little is applied, the plant will not have enough nutrients for growth, will grow slowly, and yield will be low. If too much is applied, the plant will grow excessively and the flowering period will be affected.
