I have recently bought a Rosemary bush and had one before. Would it be advisable to plant the new one in the same spot in my herb garden? The first Rosemary bush, which has now died, had some yellowed needles, and I would like to plant the new one in roughly the same area. How much space should I leave, and is it correct or advisable to plant the new one in the same bed or spot? If so, how far from the old site?
