If that picture looks like something in your lawn the first thing that you should know is that it is not crabgrass.  Crabgrass doesn’t even exist in our Cedar City climate.

Why does everyone call it crabgrass?

It is actually called tall fescue.  Although we don’t know why people in Cedar often mistakenly call it crab grass it leads to problems because people look up solutions online or buy products for crab grass and then wonder why they don’t work.  It’s like researching remedies or going to a doctor for headaches when really you have a lacerated leg.

 

How do I get rid of Crabgrass or Tall Fescue?

Now that you know what it is let’s talk about how to fix it. You have two main options:

Getting Rid of Crabgrass or Tall Fescue – Option #1:

One is organic, simple in nature, and only requires a shovel and a good back to dig out the infected area.  Be sure to get all of the roots or your problem will grow back a short time later. Once it has been dug out you’ll need to fill your hole with some nutrient-rich topsoil and then plant some new seed or sod.  Pay attention to the breeds of seed/sod you use as you wouldn’t want to introduce any more tall fescue.

Getting Rid of Crabgrass or Tall Fescue – Option #2:

Kill the tall fescue. Spray it with a glyphosate killer (example: Roundup).  Since glyphosates are non-selective herbicides they will also kill the bluegrass or wanted grass in the area so be careful.  Glyphosates can also “leach” in the soil and spread with water and/or gravity so once again, be careful.  Once you have killed all of the tall fescue you’ll want to prep the ground, and re-seed or sod it as soon as possible to prevent hostile weed takeover in your now bare patch of soil.

There’s got to be an easier way…At the time of publication, these are the best solutions we know of.  If you can come up with a better lawn care solution for fescue infestation please let us know (and you’ll probably make millions) as it is a problem we hear about almost daily.

How to Prevent Tall Fescue

  1.   Water deep and less frequently to encourage longer roots
  2.   Aerate and Dethatch each spring to encourage thick roots
  3.   Fertilize at least 4 times per year to make your lawn stress tolerant
  4.   Remove any fescue that you see before it seeds and spreads
  5.   Mow your lawn at least weekly so as not to shock it by mowing off more than 1/3 of the blade length
