Established Rosemary going Brown and dying in winter
I had two Rosemary bushes which regularly flowered during the winter. They were planted in sandy garden soil. They were about 5 years old but suddenly they have died. Can you explain why? No pictures because I have dug them up.

Watering issues are the most common reason for the loss of Rosemary plants.
They are extremely sensitive to moisture levels, and often the dying process is well underway before you can correct the situation.
