It’s additionally just a little bit of non-public desire. There are three distinct sorts that each one have completely different pruning necessities.
Three Kinds of Decorative Grasses
Correct pruning begins with figuring out your decorative grass as a sedge, warm-season grass, or cool-season grass.
Evergreen Sedges
These seem like and are sometimes mistaken for grass, however they’re not categorised as such. Reasonably, they’re within the Sedge (Cyperaceae) household of grasslike herbaceous vegetation. They’re primarily evergreen and versatile for heat or cool climate. The best option to decipher sedges from grasses is with this poetic pneumonic:
Sedges have edges,
Rushes are spherical
Grasses have nodes from their tricks to the bottom.
In different phrases, the leaves of sedges are stable and three-sided. They don’t have any joints alongside the stem.
Heat-Season Grasses
True grasses are members of the Poaceae household. Heat-weather grasses are typically known as “southern grasses.” These grasses lay dormant till late summer time, when their flowering begins. If left un-pruned, chances are you’ll acknowledge these as straw-like, brown, or dead-looking blades all through the winter months.
Southern grasses develop as much as 15 toes in peak. ‘Pampas Grass’ is a well-liked semi-evergreen grass beloved for its fluffy look and long-lasting blooms. However in lots of areas, similar to California, pampas grass might be tremendous invasive. For that reason, it’s essential to plant a sterile seedless selection.

Cool-season grasses are brief, often maturing at nearly eight to 10 inches. Nonetheless, an outlier on this class is ‘Feather Reed Grass’ (Calamagrostis), which might develop to be 5 toes in peak. ‘Tufted Hair Grass’ is a superb cool-season, semi-evergreen choice for containers, city gardens, and small areas, whereas ‘Large Feather Grass’ is a lightweight, tall, and ethereal choice that prefers gentle situations all 12 months lengthy.
‘Blue Fescue’ (brief) and ‘Karl Foerster Grass’ (tall) are fashionable cool-season grasses in northern landscapes.
Step 2: Get the Timing Proper
Some growers don’t choose the look of tall, floppy grasses of their winter backyard, so that they reduce them down within the fall after flowering. In northern zones, perennial grasses go dormant throughout the coldest a part of winter, leaving dried seed heads and fallen leaves.
Nonetheless, don’t underestimate their means to beautify an area in chilly areas. The shorter, spiky varieties look fascinating and add a cool aptitude to a backyard even after a lightweight snowfall.
Listed here are some advantages of ready to prune till spring:
- In colder rising zones, the drooped grass insulates the weak crown of the plant.
