Sedge Care Must-Knows
Sedge is one of the largest groups of plants with close to 2,000 species. Sedges can be found in almost every part of the world, thriving in different growing conditions. You can find sedge for sun or shade and for dry or moist conditions. Read the plant tag to make sure the sedge you pick will succeed in your garden climate.
Many of the native sedges growing in the United States are great for filling in between other plants, because they can be fairly vigorous spreaders by underground rhizomes. Other types are clump-forming and will stay put no matter where they are. Creeping types can easily be divided as needed to help fill in a garden space. If your sedge begins to look a little ragged, cut it back and allow it to regrow. Keep in mind that they tend to be slower growing than grasses, so only cut them back if absolutely necessary.
Sedges generally like evenly moist soil. There are some that handle droughts well, but overall they will slowly decline in dry conditions. One thing most sedges won't tolerate is wet soil. Water-logged soil can cause sedges to rot. Be consistent with your watering, whether it's on the dry side or the wet side, because sedges can become stressed from constant fluctuations of moisture.
In recent years there have been many noteworthy introductions. The Evercolor series is a group of Asian sedges that grow well in containers or as a pop of color in a shady garden. New varieties tend to feature beautifully colored variegated foliage that is evergreen in mild climates and requires very little maintenance to look good.
