Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during warmer months. Avoid waterlogging, as this can lead to root rot. Reduce watering in cooler periods when growth slows down.
Ensure good drainage to prevent excessive moisture buildup around the roots.
Pruning is generally not required for Supine Bluegrass, as its growth habit is low and spreading.
If it becomes overgrown or straggly, you can lightly trim it back in late spring or early summer to maintain a tidy appearance. Remove any dead or damaged foliage as needed.
Propagate Supine Bluegrass by division in early spring or autumn. Carefully separate clumps of the plant, ensuring each section has roots and shoots. Replant the divisions immediately into well-prepared soil.
It can also be propagated by seed sown in autumn or early spring.
Repotting is typically not necessary for this groundcover species, as it spreads to fill its intended space.
If growing in containers, repot every 2-3 years in spring into a slightly larger pot with fresh, well-draining potting mix. Ensure the root ball is not overly compacted.
