Catmint are easy to grow provided you find them a sunny or partially shaded spot and a well-drained soil, they will not tolerate heavy soils that are prone to waterlogging. Water regularly during the first season, but once established they are heat and drought tolerant, making them an excellent choice for dry areas of the garden. In spring apply a layer of organic mulch around the planting area, this helps keep the roots cool, retain soil moisture and deter weeds while giving plants the nutrients they need to remain healthy. Remove faded flowers to prolong flowering. Once flowering has finished leave the tired foliage in place over winter to help protect the crown, wait until early spring to cut it back. To keep Catmint vigorous, divide it every three to four years in either spring or early fall.
