Container-grown plants require more frequent watering than those planted in the ground as soil in pots dries out more quickly.
A layer of mulch on the surface of the potting medium can help retain moisture. If the plant outgrows its container, it should be divided and repotted every two to three years.
Where to Buy
You can find ‘Zebrinus’ in most good garden centers and nurseries.
If you prefer to shop online, you can find plants available in #1, #2, and #3 containers at Nature Hills Nursery.
A similar, dwarf cultivar, ‘Little Zebra’ has the same care requirements but only grows to four feet tall and three feet wide.
The plumes are a little darker than those of ‘Zebrinus.’
You can find ‘Little Zebra’ available from Fast Growing Trees.
Maintenance
‘Zebrinus’ requires very little attention beyond an annual cleanup and occasional division.
In late winter or early spring use a clean pair of pruners to cut back the dead foliage to a few inches above the crown.
If the clump becomes too large or starts to die out in the center, it’s time to divide. This typically needs to be done every three to five years.
Dig up the plant in early spring and use a sharp spade or saw to slice through the root ball.
Each division should have both roots and viable shoots. Replant at the original depth and water well.
Plants growing in partial shade or overly rich soil may flop open in the center. If this happens, reduce feeding and consider staking the plant or relocating it to a sunnier spot.
Apply a few inches of mulch around the base in spring to help retain moisture and suppress weeds, but keep it away from the crown to prevent rot.
If you live in a windy area or experience heavy snow in winter, leaving the dried foliage in place until early spring can provide some protection for the crown and add visual interest to the garden during the colder months.
Propagation
You can propagate zebra grass by division or by transplanting nursery starts.
Starting from seed is theoretically possible but many ‘Zebrinus’ plants are sterile or rarely set viable seed. Additionally, seed-grown plants may not grow true to the parent.
By Division
Dividing an established plant is the most efficient way to propagate zebra grass.
In early spring, before new growth appears, dig up a mature clump.
Use a sharp spade or saw to cut the plant into sections, ensuring each piece has both roots and shoots.
Replant the divisions at the same depth.
Water thoroughly and apply mulch to help retain soil moisture and suppress weeds.
