Pro Tip – Ornamental grasses are either warm or cool season. Cool Season grasses will emerge earlier in the season. Warm season grasses require not just warm air, but also warm soil to start growing. Unless noted, ornamental grasses perform best in full sun, which is at least 6 hours of sun per day.
Ornamental grasses should be left standing through the winter months for multiple reasons. It provides food and coverage for birds and insects in the fall and winter months. It also adds winter interest to the landscape. By leaving the foliage covering the crown, you are also protecting the crown of the plant in case we have extremely cold temperatures without much snow cover.
In the spring, you need to cut all grasses back to about 3″ so the new growth can push through and start growing.
