Festuca , a predominantly hardy and perennial genus, presents simple care needs. Generally, festuca s require full sun for ideal growth and thin watering, as they thrive in well-drained, loamy soil. Temperature tolerance varies by species, but most withstand cold and drought. Common challenges for festuca include rust, mildew, and insect pests like aphids. These can usually be controlled with careful monitoring, proper watering, and periodic application of insecticides or fungicides. Seasonal care includes early spring fertilization and summer pruning to encourage new growth. Over winter, festuca s generally need less water and care as they naturally go dormant.
