Mixing Fescue and Ryegrass for Winter Erosion Control

When soil temps are above 55°F, fescue alone germinates well—no rye needed. In cooler months (Dec-Feb), a mix can help: rye germinates fast as a nurse grass, but limit it to 40% of the blend. A ratio of 2 lbs rye + 3 lbs fescue per 1000 sq ft meets the standard 5 lbs total rate. This ensures quick cover for certificates of occupancy while establishing permanent fescue.
