To maintain a healthy Festuca and promote new growth, it is advisable to divide the plants periodically. This process is simple: remove the plant from the ground, divide it into pieces and replant the parts. The best time to do this is in spring or fall. Festuca has average water requirements; it is important to adjust watering according to weather conditions and the type of soil the plant is in. In prolonged drought, extra watering may be necessary to keep the plants healthy and beautiful.
