Water regularly, especially during the first growing season. Once established, it is relatively drought-tolerant, but it still benefits from occasional watering during dry spells.

When is the best time to prune this grass?

Prune in early spring before new growth emerges to remove dead foliage.

Can this grass grow in full shade?

While it tolerates partial shade, it thrives best in full sun, which is at least 6 hours of direct sunlight per day.

What kind of soil does this grass prefer?

It prefers moist but well-draining soil. Amending the soil with compost can improve drainage and fertility.

How tall does this grass get?

Typically grows to be around 3-5 feet tall, including the flower stems.

Are the flowers fragrant?

No, the flowers are primarily valued for their visual texture and color.

Is this grass invasive?

It is not generally considered invasive, but it can spread through rhizomes. Careful placement is advisable.

Troubleshooting

Yellowing or browning leaves

Check for overwatering or underwatering and adjust watering accordingly. Ensure the soil has good drainage.
