- Make sure each division is healthy and free from any signs of disease or pests.
5. Prepare the New Planting Area
- Choose a sunny location with well-drained soil. Amend the soil if necessary to improve drainage.
6. Plant the Divisions
- Dig holes that are slightly larger than the root balls of the divisions. Place each division in a hole, ensuring the crown of the plant (where the roots meet the shoots) is level with the soil surface.
- Backfill the holes with soil and gently firm it around the roots. Water the new divisions thoroughly to help them settle in.
7. Aftercare
- Keep the soil consistently moist but not waterlogged while the new divisions establish. Once established, Blue Fescue is drought-tolerant and requires less frequent watering.
- Mulch around the plants to retain moisture and suppress weeds, keeping the mulch away from the base of the plants to prevent rot.
Propagation by Seed
While less common, Blue Fescue can also be propagated by seed. Here’s how:
1. Collect Seeds
- In late summer, after the flowers have faded and the seed heads have matured, collect the seeds from the plant.
2. Prepare Seed Trays
- Fill seed trays or pots with a well-draining potting mix. Lightly moisten the soil.
3. Sow the Seeds
- Sprinkle the seeds evenly over the surface of the soil and lightly press them into the soil. Do not cover the seeds, as they need light to germinate.
4. Germination
- Place the trays in a bright location but out of direct sunlight. Keep the soil consistently moist.
- Seeds should germinate in 2-3 weeks. Once the seedlings are large enough to handle, they can be transplanted into individual pots or directly into the garden.
5. Transplanting
- When the seedlings have developed several true leaves and are large enough to handle, transplant them to their final growing location, spacing them about 12-18 inches apart.
By following these steps, you can successfully propagate Blue Fescue Grass, ensuring a healthy and vibrant addition to your garden.
