Red fescue is a resilient, cool season grass that spreads through underground stems called rhizomes. It is a popular choice for lawns because it handles shade and poor soil quite well. You will often find it mixed into seed blends for its ability to create a fine textured turf.

Care
Keep the soil consistently moist while the grass is establishing itself. Watch for yellowing blades which might indicate it needs more nitrogen or better drainage. Mow regularly to keep the grass at a healthy height, but avoid cutting it too short during hot spells.
- Watering
- Water deeply once or twice a week to encourage strong root growth.
- Feeding
- Apply a balanced fertilizer in early spring and again in early autumn.
- Pruning
- Mow frequently during the growing season to maintain your desired height.
- Repotting
- This is a lawn grass and is not typically grown in containers.

- Well draining, sandy or loamy soil
- Soil pH
- 5.5 to 7.5

- -35 to 30°C

- Lifespan
- Perennial, typically 3 to 5 years before needing division.
- Deer and rabbits
- Moderate
Signs it needs repotting
- Roots growing out of the drainage holes.
- Water sitting on the surface instead of soaking in.
- The plant looks crowded and stops spreading.
Safety
- People
- It is generally considered non toxic to humans.
- Children
- The sharp, pointed tips of the grass blades can scratch delicate skin, so keep an eye on small children playing in dense patches.
- Contact allergens
- The fine, stiff leaf blades can cause minor skin irritation or small cuts if handled roughly.
- Airborne allergens
- The pollen produced during the flowering season can trigger hay fever in sensitive individuals.
- Edibility
- This grass is not intended for human consumption and may cause digestive upset.
How to identify it
- Fine, needle like leaf blades
- Deep green to blue green color
- Spreads by underground rhizomes
- Forms dense, low growing clumps
- Height
- 0.1 to 0.6m
- Spread
- 0.15 to 0.3m
- Leaves
- green, blue-green, evergreen
- Flowers
- green, brown, 0.5 to 1cm
Problems to watch for
- Red thread · A fungal disease that causes pinkish, thread like growth on the grass blades during humid weather.
- Dollar spot · Small, bleached spots appear on the lawn during periods of high humidity and warm temperatures.

Growing it
- Propagation
- division, seed
- When to plant
- spring, early autumn
- Overwintering
- It stays green in mild winters and requires no special protection. In colder regions, the foliage may turn brown but will regrow from the roots in spring.
- In containers
- It grows well in containers, provided the pot has excellent drainage and is at least 20 cm deep.
Division
- 1. Dig up a mature clump in early spring.
- 2. Gently pull the clump apart into smaller sections.
- 3. Replant the sections immediately at the same depth.
Pair this grass with low growing woodland perennials to create a stable, weed suppressing carpet.
Grows well with
- Wild Strawberry · They share similar light requirements and create a lovely ground cover layer.
- Columbine · The delicate foliage of the columbine contrasts beautifully with the fine texture of the grass.
Similar species
- Sheep Fescue · It has a similar clumping habit but is better suited for very dry, rocky soils.
