How to Fertilize Rosemary? A Full Breakdown of the Latest Methods
Rosemary is a shrub in the Lamiaceae family, native to Europe and Africa. During the growing season it gives off a fresh fragrance, can be used to extract aromatic oil, and also contains antioxidant substances. It has calming, soothing and mind-clearing effects, and 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 us take a look below at how to fertilize rosemary.
1. Fertilizer selection
Before fertilizing, you must first choose the fertilizer well. A flower fertilizer rich in phosphorus and potassium is most suitable. 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 method
Before fertilizing, first remove the weeds completely. Open a shallow trench near the root system, but not too close to the roots, so that the fertilizer is not too concentrated and burns 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 may also water it a little to speed up the dissolution of the fertilizer so that it is absorbed as quickly as possible. After each harvest, apply fertilizer once as well; the main components of this fertilizer are nitrogen and phosphorus, so that the plant can grow a second time and the next harvest will be better.
3. Points to note
Fertilizing rosemary is a careful job. Besides choosing the fertilizer, 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 does not have enough nutrients to grow, so it grows slowly and yields poorly, while if too much is applied, the plant grows leggy and its flowering period is affected.
