We turn to planting ornamental grasses to recreate the curves and meanders of nature’s hand. Ornamental grasses provide four seasons of interest and are widely adaptable to many conditions. Be sure to always plant them in a full sun location in well-draining soil.
While landscaping, consider when to cut back your ornamental grass plantings. Letting it grow tall will enable seed heads to develop, which you may or may not want as part of your garden design, with its intended consequence of reproduction. For example, Mexican Feather Grass can double in size if left unattended. Cutting it back will trim off these seedheads and rejuvenate the plant, much like removing flowers by deadheading. Chopping off ⅓ to ⅔ of the uppermost portion of Mexican Feather Grass will give it an angular, more modern look. On the other hand, Foxtail Millet is grown precisely for the seedheads, which grow beautifully greenish-tan, nutty and coarse. You may want to leave this addition in your garden, or harvest to decorate inside your home. These seedheads stand up well in vases, and have become a favorite of floral designers.
Pampas Grass grows tall plumes atop sharp, long blades. These plumes can readily be dried, arranged and used to decorate inside and outside the home. If you like the look of the plumes on the plant, the best time to cut these back will be in late winter. Waiting until this time allows you to enjoy the fluffy, cloud-like plumes in your landscape. When it is time to cut back, it is best to chop ⅔ off the top.
