Plant guide

Kuma bamboo grass.

Sasa veitchii

Pronounced SAH-suh VEE-chee-eye

Also known as Veitch's Bamboo, kuma bamboo grass

This is a lovely, low growing bamboo that makes a wonderful groundcover for shaded areas. It is famous for its unique foliage that develops a papery, white margin as the leaves mature in winter. It spreads through underground rhizomes, so you will want to keep an eye on its boundaries.

Care

Plant this bamboo in a spot with protection from harsh afternoon sun to keep the leaves from scorching. Keep the soil consistently moist but not waterlogged, and watch for aggressive spreading if you have not installed a root barrier. If the leaves look brown or crispy, it is likely asking for more humidity or shade.

Watering: Keep the soil evenly moist, especially during the first year of establishment.
Feeding: Apply a balanced, slow release fertilizer during the active growing season in spring and summer.
Pruning: Cut back old or damaged culms in early spring to encourage fresh, vibrant growth.
Repotting: If growing in a container, repot when the rhizomes become too crowded and begin to push against the sides.
Soil: Rich, well draining, loamy soil
Soil pH: 5.5 to 6.5
Temperature: -20 to 30°C
Humidity: 40 to 70%

Growing it

Propagation: division
When to plant: spring, autumn
Overwintering: No special winter care is needed as it is quite hardy, though a layer of mulch can help protect the roots in colder regions.
In containers: It grows well in large, wide containers, but you must ensure the pot is sturdy enough to withstand the pressure of the expanding rhizomes.

Rhizome Division

1. Dig up a section of the clump in early spring.
2. Use a sharp spade to cut a piece of the rhizome with attached roots and shoots.
3. Replant the division immediately into moist, well draining soil.

Always install a deep root barrier when planting this bamboo to prevent it from overwhelming your other garden companions.
