Once established, Northern Sea Oats can tolerate periods of drought, but regular watering will help it thrive. Water thoroughly once a week, or more during periods of extreme heat. Avoid overwatering, as this can lead to root rot.

Trim back Northern Sea Oats in late winter or early spring, before new growth appears. Cut the stems down to a few inches above ground level to make way for new growth.

Dividing

Over time, Northern Sea Oats may spread and become crowded. To refresh the plant and maintain its health, divide it every three to four years in the spring. Dig up the clump and separate it into smaller sections, then replant in a fresh location.
