Lawn care causes crabgrass?
"Kurt Tappe" wrote in message news:2004072413081516807%ktappe@NOvoicenetSPAMcom. .. snip So guess whose lawn has been taken over by crabgrass? The infestation literally stops at the property line. My (former) lawn is 90% crabgrass while my negiligent neighbors have attractive grass. The obvious conclusion is that my efforts are somehow causing/allowing the crabgrass to flourish. I wait until the lawn is pretty high to mow--no scalping is taking place. I have not put pre-emergents down...but neither did the neighbors. Could the weed & feed be weakening the grass enough that the (apparently immune) crabgrass can take hold? If so does this mean the whole weed & feed concept is a farce? Keep one thing in mind, true Crab Grass is an annual grass, not a perennial. This years crab grass will not be your problem next season. It is this years seeds that will germinate next year. So controlling Crab Grass means to prevent the seeds from germinating the next season. Pre emergent lawn treatment early spring should help prevent the previous years seeds from germinating. Also a good healthy crop of dense truf grass will also squeeze out crab grass and help keep seeds from germinating. When you mow your grass, set the mower deck higher than it is now, unless you already mow high. Cutting your truf too low will give your neighbors crab grass the sun it needs to germinate. Keep your lawn thick and lush to prevent it crab grass from growing in your lawn. Here a several links that may help. http://www.growinglifestyle.com/h/pest/crabgrass/ I am not sure which product has pre emergent in it. If it is Weed And Feed make sure it is applied at the right time for your zone. Look for the words pre emergent on the bag. And apply it at the recommended time. Weed and feed applied here has helped control run away ground covers such as ajuga. It is doing something good but you need the right product for the job you want done. Take a specimine of the grass you are calling crab grass, to your county extension office to make sure it is indeed crab grass. There are other grasses that are invasive that look similar to crab grass. For example, Bermuda Grass creeps and spreads where it is not wanted. Bermuda grass seed is found in some grass mixes.
