Rosemary gone to wood
I moved my outdoor rosemary inside last fall and it seemed to adjust ok. About 6 weeks ago it started getting really dry and several of its growing shoots fell off. Now it has only one shoot left, which has dried out, leaving nothing actively growing and soft on the plant. Is it a lost cause? Is there anything i can do to revive it?
You are not alone in issues with growing Rosemary plants indoors.
If the plant has died, it will not come back.
Try snapping the stems and if they break, they are no longer alive.
