How to Incorporate Decorative Grasses in Your Landscape
Now that we’ve explored some great options, let’s discuss how to best incorporate these grasses into your landscape design. Here are some practical tips based on my personal experiences:
1. Use Grasses as Focal Points
Ornamental grasses can serve as excellent focal points in your garden. Consider grouping several together or planting them near pathways to draw the eye.
2. Mix and Match Heights
By combining grasses of different heights, you can create depth and interest in your landscape. Taller grasses can provide a backdrop for shorter ones, making for a dynamic display.

Using decorative grasses as natural borders can help define areas of your garden. This technique can add structure to your landscape without the need for more rigid elements like fences or walls.
4. Layer with Perennials and Shrubs
Grasses pair beautifully with a variety of perennials and shrubs. Consider plants that bloom at different times of the year to keep your garden lively throughout the seasons.
Care and Maintenance of Decorative Grasses
While many ornamental grasses are low-maintenance, some care is still required to keep them looking their best:
Watering Tips
Most grasses establish deep root systems, which help them weather Colorado’s dry conditions. However, newly planted grasses will need regular watering until they’re established.
Fertilization
Feeding grasses can promote healthy growth. A slow-release fertilizer in early spring can provide the nutrients they need to thrive.
Pruning and Cleanup
Pruning is essential for maintaining the health of your grasses. In early spring, cut back dead foliage to encourage new growth. Remember, the grasses will often look great even in winter!
