Q.I have a large rosemary bush that is failing
Large old rosemary bush. Ten years old. About half of the bush is turning brownish/yellow and dry. Does it need lime or fertilizer? Or is it just getting old? Really hate to lose it. Thank you!

It is likely just getting old. But, it could also be affected by a fungus. I would recommend treating it with a fungicide and see if that will help it. If it does not, then it may be time to replace the plant.
