Should I cut back ornamental grasses in the fall? The answer depends on the type of ornamental grasses you have and your aesthetic preferences. While some gardeners choose to trim their ornamental grasses in the fall for a tidier look, others prefer to leave them until spring to enjoy their winter interest and provide habitat for wildlife.
When to Cut Back Ornamental Grasses
Fall vs. Spring: Which is Better?
Deciding whether to cut back ornamental grasses in the fall or spring involves considering several factors, including the type of grass and your garden’s climate. Here are some considerations:
- Fall Cutting: Some gardeners cut back grasses in the fall to prevent them from becoming messy and to prepare for winter. This is ideal for warm-season grasses that go dormant in the fall.
- Spring Cutting: Leaving grasses until spring can add visual interest to a winter landscape. It also provides shelter for wildlife and protects the root system from harsh winter conditions.
Types of Ornamental Grasses
Different types of ornamental grasses may require different maintenance approaches:
- Warm-Season Grasses: These grasses, such as switchgrass and maiden grass, thrive in warmer climates and typically go dormant in fall. They can be cut back in late fall or early spring.
- Cool-Season Grasses: Grasses like fescue and blue oat grass grow actively in cooler months and may not need cutting back until early spring.
