How to get rid of ants under rosemary bush in the ground?
I have a large rosemary bush planted in the ground. The past few months I have noticed it is not as full and green as it has always been; some sections are turning brown and dying off. I noticed today there is an ant hill in the roots. Are the ants the cause of my rosemary plant’s declining?
