Rosemary – Help After Extreme Cutting
A very large group of rosemary bushes (20 ft in diameter) in a city park was trimmed in an extreme manner - to the ground in an effort to kill the plants - by the parks dept. Is it possible to regrow the plants from the root structure in ground or do we need to replant? If the root structure will regenerate, what is best way to regrow the plants?
