When and How to Trim Ornamental Grasses in Olympia, WA

In Olympia, WA, the best time to trim ornamental grasses in the spring is in early spring (late February to early April) after the snow has melted and before new growth emerges. 

Here’s a more detailed guide:

• Timing is Key:
•  Late February to Early April: This is the ideal time to trim ornamental grasses in the Olympia area, as it allows you to remove dead or damaged foliage without harming the new growth. 
• Wait for Snow to Melt: Don’t trim until the snow has melted and the ground is no longer frozen. 
• Before New Growth: Trim before the new growth starts to emerge, which typically happens in early spring. 
• Tools of the Trade:
• Pruning shears or hedge trimmers: Use sharp tools for a clean cut. 
• Gloves: Protect your hands while trimming. 
• How to Trim:
• Cut back to 1/3 to 1/2 of the plant: For evergreen grasses, prune back only 1/3 to 1/2 of the plant. 
• Remove dead or damaged leaves: Focus on removing any dead, damaged, or diseased foliage. 
• Leave a few inches of stubble: This helps protect the crown of the plant from the cold. 
• Benefits of Spring Trimming:
• Promotes new growth: Trimming in early spring encourages healthy new growth. 
• Removes debris: It helps to remove unsightly dead foliage and debris from the winter. 
• Improves appearance: A well-trimmed grass clump looks neater and more vibrant.
