Care Guide
Planting
Plant Creeping Fescue in fall or spring in a location with full sun or partial shade. This cool-season grass tolerates many soil types and prefers medium drainage, so amend heavy clay if water pools after rain. Space plants according to your cultivar's mature width (typically 1–3 feet tall), and choose a spot where it can spread via rhizomes without overwhelming neighboring plants.
After Planting
Water weekly during your first summer to establish the plant, then taper to once monthly or less once established - this is a drought-tolerant grass that thrives on minimal summer water in the Bay Area. Expect summer dormancy (the plant will brown and slow down) as this is a cool-season species; this is normal and not a sign of failure. You can mow it like a lawn, leave it unmowed for a prairie look, or anything in between; prune or mow in spring as new growth emerges. The #1 mistake is overwatering once established - resist the urge to irrigate in summer unless there's a heat wave, as this grass prefers drier conditions.
