How to Keep a Rosemary Tree

Rosemary plants are versatile, providing fresh aromas throughout the house, spices for cooking, and as a decoration most suitable during the Christmas season. The small pine needles can be added to recipes including lamb chops and teas while also resembling a miniature Christmas tree that can hold lightweight ornaments. The trees thrive outdoors but need to be protected from freezing temperatures, insects and fungus growth.
