nut sedge
Comments (5)I can testify that IF you pull it and pull it and never let it get big and lush, you will eventually get rid of it.That, of course, is a tall order in an established patch of it. Also, if your ground is soft and has a crumbly tilth, you can dig it out. There are thick runners from the foliage tufts near the surface of the soil and the tufts put thread thin brown runners that go straight down about 4 to 6 inches. These have the nuts on them. If you dig carefully, you can get it out, but you have to get both kinds of runners. I have also had good luck wearing a rubber glove and dipping my fingers into a Nutsedge Killer (Image or Ortho's) and running my fingers through the sedge. Two applications, a week apart, will usually kill it to the root. I tend to keep it dug and pulled from my vegetable beds and to use the chemical controls in my flower beds. You need to know that the nuts can lay dormant in the ground for years and then sprout in response to wet conditions. So, it's an ongoing fight. I have found if I stay on top of it, over time, I have gotten control of it in my beds. Now, in my lawn? Not so much. I hate that stuff. Oh, and don't forget this thing also makes seeds. For goodness sake don't let it make seeds!...See Morenut sedge...........
Comments (17)started the process of weeding in the asparagus patch 1st. this stuff is deeply entrenched. it's almost like it's one single organism. hand weeding is my only option around the asparagus but I'm writing off the rest of the garden. I'm potting some tomatoes & peppers. the rest I mowed & tilled & will work on the rest of the summer & fall to get this sedge under control. my thinking is that this will save me a lot of effort in years to come. this stuff is unbelievably tenacious. on the lower end of the garden I have a row of straw bales to prevent erosion. the sedge has traveled under it & up threw it. I've read that after repeated weeding the tubers ( nuts ) will eventually lose the ability to reproduce. so my plan is to till the garden & try solarization for 2 weeks, till, solarize for 2 weeks, till.....repeating all season & a heavy planting of buckwheat & alfalfa in the fall for a green manure. i'll also use limited chemical warfare in hard to work areas. also-I'll never use leaf or ground tree mulch from local municipalities. I'm sure that that's where this crap came from. if anyone has any other techniques I'm open to suggestions. http://www.caes.uga.edu/commodities/fruits/veg/pubs/GFVGA%202007/documents/Johnson-11.pdf...See Morecontrolling nut sedge!!
Comments (4)Understanding about sedges can help in controlling them some. Sedges evolved as wet land plants and althouigh theuy have adapted to growing in drier areas they still need that wetter than normal soil to get started. Mulches provide the ideal habitat for Yellow Nut Sedge to grow in, the cool, moist, soil they evolved in. Correcting the soil conditions is one method of control and digging the "nuts' the rhizomes that produce the plants is another. There are poisons that you can spray that will kill the Yellow Nut Sedge as well as any other grass it contacts, but unless the soil conditions are corrected new seeds ,brought in by the birds, could germinate and grow to replace what you just killed. I see Yellow Nut Sedge growing in lawns and gardens that are sprinkled every day but do not see it growing where the lawn or garden is watered only once a week or so....See MoreNut Sedge and Lamium control
Comments (5)Thanks to all! Really appreciated!! Gives me a less panicky approach. Can't lift the plants and move to treat in this situation, but it is late in the season, so there is time to strategize for next spring. For now, in the 'nut sedge' bed, it has been heavily weeded out, but the nutlets are everywhere. I will try Round-up on any little regrowth this fall, and will look at getting Sedgehammer for the spring . I will clear out as much of the Lamium, and all the runners I can find, and then hit new growth in the areas I have tried to clear. And then work on clearing the next patch, and ditto. One step, then another. But there is so much left to do that I couldn't spend all my limited time on weeding out the same weeds.......See More- 8 years ago
