Care Guide
Planting
Plant Siskiyou Blue fescue in full sun to part shade in well-draining soil with poor to moderate fertility. This compact grass (reaching 1-1.5 feet) tolerates a range of soil types, so amend heavy clay only if drainage is truly poor. Plant in fall or spring for best establishment, spacing plants about 12-18 inches apart to account for mature spread. It's deer resistant, making it a low-maintenance choice for mixed borders or groundcover areas.
After Planting
Water weekly during the first summer to establish a strong root system, then transition to low water once established - this is a drought-tolerant plant that actually prefers drier conditions once settled in. Siskiyou Blue is evergreen and cold-hardy, so it will look good year-round in the Bay Area with no dormancy period to worry about. The biggest mistake people make is overwatering; this grass thrives on neglect rather than fussing, and too much water invites root rot. Minimal pruning is needed - just remove any dead or damaged foliage in early spring if desired.
