Creeping Red Fescue
LawnFestuca rubra, Red Fescue, Creeping Fescue
Exceptionally shade-tolerant cool-season grass; thrives under tree canopy where other grasses fail. Ideal for low-maintenance and naturalistic lawns in zones 2–7 (Northern Europe, Canada, Northern US). Fine-bladed texture; spreads slowly by short rhizomes. Tolerates dry, infertile, acidic soils better than any other lawn grass. Mow at 4–7 cm; can be left unmown for a meadow effect. Very low fertiliser needs — over-fertilizing promotes disease. Red thread is common in nitrogen-deficient conditions: a light autumn feed usually prevents it. Avoid compaction — aerate every 2–3 years. Does not tolerate heavy foot traffic or waterlogged soils. Often sold in shade or low-maintenance lawn seed mixes blended with other fescues.
When to sow creeping red fescue
Sow 6–8 weeks before your first autumn frost.

How to establish and care for creeping red fescue
- 1
Sow
Sow in early autumn or spring. It is the best lawn grass for shade under trees.
- 2
Mow
Mow at 4–7 cm, or leave it unmown for a meadow look.
- 3
Feed little
It needs very little fertiliser and copes with dry, poor, acidic soil. Too much feed brings disease; a light autumn feed is enough to prevent red thread.
