Rosemary leaves browning from the tips to the base. This rosemary plant is in ground outdoors in a sandy clay loam bed that I double dug last year with compost before planting. It faired really well over the summer but since December the weather in our area has been cold and damp (we’ve had several snow storms since the beginning of January and it has taken a while for things to dry out). I’ve dug the plant up and am taking it inside but the roots appear to be fine (not mushy or otherwise showing signs of rot). What could be the problem?
