Nutsedge is a pesky perennial weed that doesn’t play around.  Although it is sometimes called Nutgrass, it is technically not a grass but rather from the sedge family.  As the summer heats up nutsedge becomes more evident, with its light green color and unusual triangular blades that grows faster than the rest of your grass. 

More often than not we see nutsedge in neighborhoods that were once farm ground.  Not only is nutsedge a problem in agricultural fields but it is also easily spread when topsoil is added during new construction.  It can also be spread when planting ornamental plants from nurseries. 

What makes this perennial weed so invasive is the small underground tubers called nutlets that grow underneath the soil.  One single nutsedge plant can produce hundreds of tubers in the summer.  Frost will kill the above ground part of the plant in the winter but the tubers will survive and germinate throughout the spring and summer. 

Once your know your lawn has nutsedge you will have to become aggressive in combating it.  If you choose to tackle this weed by hand it is recommended that you use a digging tool rather than just pull the weeds.  You will need to dig deep, as far as 14 inches down in order to remove the nutlets and seeds.  Any remnants of this weed will re-spawn new growth.  Fill any holes you create with compost.

There are chemical treatments available for nutsedge but it is important to remember that as with most weeds, that chemical herbicides are just treating a symptom rather than the problem.  When nutsedge is flourishing in your grass it is usually because of compacted soil, overwatering, and/or lack of nutrients in your soil.

The best defense against nutsedge as with most weeds is to practice the principles for a healthy dense lawn.  To begin make sure that you are not mowing your lawn too short, a short cut will only encourage nutsedge growth, mowing at a higher setting will help your lawn grow better. 

Besides mowing, applying fertilization will not only address a lack of nutrients in the soil but an organic fertilizer will also naturally aerate your soil and help to combat the issue of soil compaction.  Soil compaction could be one of the causes for the swampy environment that nutsedge thrives in. 

Overwatering is one of the most common causes of nutsedge problems in Idaho lawns.  Idaho is naturally a desert environment and the modern sprinkler system has done wonders to help us water our lawns efficiently.  Unfortunately many people believe that their grass needs to be watered constantly, especially in the hot days of summer.  Actually your lawn will be healthier and nutsedge and other weeds will be less likely to survive if you water only a couple of times a week.  Deep, infrequent watering is better for your grass and better for the environment.
