Don't let nutsedge steal the show from your tulips and daffodils. Here are three ways you can help prevent nutsedge from invading your landscape beds:  --Increase shade. Nutsedge doesn't grow well in the shade. Plant a tall, dense ground cover or shrub that shades out the weed. Keep in mind that low-growing ground covers won't shade out nutsedge.  --Install landscape fabric. Love it or hate it, landscape fabric can offer a temporary weed-control solution. Cover the fabric with mulch, such as bark or gravel.  --Avoid contaminated soil. If your soil supplier can't guarantee tuber-free soil, don't use it in your landscape beds.  --Remove nutsedge as soon as it sprouts in your flower beds. Otherwise, it will produce tubers and grow out of control.
