Why does rosemary turn black?

Rosemary is one a typical plant of cold regions and high latitudes (grows in the mountains, above 800 meters above sea level) and needs very little water to survive: this can also be seen in the needle-like leaves, developed precisely to minimize water consumption.

Although it is possible to grow rosemary in our latitudes, on the balcony of the house, it is important to remember the characteristics of the plant so that we can deal with it in the most correct way.

If we notice that the leaves gradually turn black (first at the tips, then along the entire length), the reason may be excessive watering, which causes rotting of the roots in the soil.

If you want to solve this problem before it is too late, it is advisable to transplant the plant. We take the plant out of the soil and carefully clean the roots: if necessary, we cut off those that are rotten and irreparable, and we keep those that are still healthy.

Let’s take a new pot for our plant and choose drainage soil, put a layer of pebbles or clay on the bottom of the pot to help excess water escape.
