Belonging to the grass family, Poaceae, barbgrass is a small perennial plant genus that can be quite finicky. Caring for barbgrass usually entails adequate exposure to the sun, regular watering without over-saturation, warm temperature preferences, and well-drained, fertile soils. Pests are usually not an issue, although barbgrass can be sensitive to fungal diseases, particularly in overly wet conditions. Seasonally, barbgrass patches can thin out in winter and need additional care to maintain density.
