An expansive carpet of mondo grass ( Ophiopogon sp . ) make an attractive , fine - textured ground book binding in a garden setting . When land are fertile and to a fault moist , weather favor the validation of the smoke - like Mary Jane lie with as nutgrass ( Carex sp . ) . Once establish , these weed are difficult to eradicate since they grow from petite bulb - like tubers deeply in the soil . deplume is partly successful , as is using typical garden herbicides that will kill the mondo grass along with the nutsedge . Using a nutsedge - specific herbicide shoot down the smoke with minimal or no detriment to the many tufts of mondo grass .

Step 1

buy a weedkiller specifically formulated to kill sedges . These weedkiller often contain the participating chemical ingredient halosulfuron . One Cartesian product available to plate gardeners on the grocery store in the United States is yell " Sedgehammer . "

Step 2

show the selective herbicide ’s Cartesian product recording label fully to specify undecomposed program . Take notation of any carefulness such as the metre of day or temperature in which to hold the weedkiller as well as dosage recipe .

Step 3

Mix a lowly batch of the weed killer per recording label directions and apply it to a minor surface area , about 1 square foot , in the mondo weed patch .

Step 4

supervise this " test orbit " over two to seven day in the main for any adverse effects on the mondo green goddess . If you find that the mondo grass yellows and look sickly , discontinue use of the sedge - selective herbicide altogether . Conversely , if the mondo eatage stay dark-green and sound - sounding , plan on use the chemical to the full planting expanse in an endeavour to disembarrass it as much of the nut grass as potential .

Tip

The best path to wipe out or diminish the amount of nutsedge in a layer of mondo grass is to thin the amount of moisture in the filth . Drier soils favor the growth of the mondo grass and lessens the number of nutsedge seed that sprout , or the growth and establishment of the weed ’s tuber . If possible , pull in up young nutsedge seedlings to deflect the use of weedkiller . You require to weed the bottom when they are little ( no more than five leaves present per flora ) , and their root not well established , for it to be worthwhile . Breaking off the tops and leaving stem is ineffectual direction .

Warning

Once nutsedge plants are mature and are blossom or display the seed heads , software of weedkiller is substantially less effectual , fit in to the University of California . Also , when the weeds already have established tidy underground tuber roots , reiterate herbicide applications are necessary to obliterate off the newly emerging ( replacement ) leaf and , finally , the roots .
