Care Guide
Planting
Plant Bottlebrush Squirreltail in full sun and well-draining loamy or clay soil - it performs poorly in sandy soils, so amend if needed. Space plants about 2 feet apart to account for their mature width. Spring is the ideal planting time to establish roots before the dry season.
After Planting
Water weekly during your first summer to help the plant establish, then transition to very low water once it's growing vigorously, typically by late summer or fall. This native perennial will go dormant in summer and green up again in winter and spring; resist the urge to overwater during dry months. The #1 mistake is planting in sandy soil or underestimating how drought-tolerant this grass becomes - once established, treat it like the dry-site native it is.
