Plant Care & Growing Tips

Caring for your feather reed grass live plant, ‘Cool As Ice’, is straightforward, ensuring a beautiful display year after year. This grass prefers a location with full sun to partial shade, meaning it needs at least 6 hours of direct sunlight daily for optimal growth and plume production. While it can tolerate some shade, too much will result in weaker growth and fewer flowers. It is adaptable to various soil types but thrives best in well-draining soil. Avoid heavy clay soils that retain too much moisture, as this can lead to root rot. If your soil is poor, amend it with organic matter to improve drainage and fertility.

Watering should be consistent during the first growing season to help establish a strong root system. Once established, ‘Cool As Ice’ is remarkably drought-tolerant and will only require supplemental watering during extended dry periods. Overwatering should be avoided. Fertilization is generally not necessary; if your soil is particularly poor, a light application of a balanced slow-release fertilizer in spring can encourage growth. The most important maintenance task is cutting back the foliage. In late winter or early spring, before new growth appears, cut the entire plant back to about 4-6 inches from the ground. This promotes healthy new growth and maintains its tidy appearance. This perennial ornamental grass is hardy in USDA zones 4-9, tolerating a wide range of temperatures. It is generally pest and disease resistant, making it a very reliable garden performer. Understanding feather reed grass care ensures a thriving and attractive display.
