Q.Rosemary plants turning brown
Large areas of my 6 + year old rosemary plants are all having large areas turning brown and dying. I tried cutting out the affected areas but it’s not helping much. There is no sign of insects and watering has been consistent for years so I know it’s not that. They are all planted in a row and are all having similar problem.

If your plants have been healthy for several years, then suddenly start browning, something in their environment has changed. Pay attention to possible changes in light, water, and soil. Also, is it possible they were affected by cold winter weather? This article should help you: https://www.gardeningknowhow.com/edible/herbs/rosemary/brown-rosemary-plants.htm
