Crabgrass article

So what’s going to happen to crabgrass this year??

We’ve had a brutal winter here in the Midwest.  The cold weather has killed off all of the crabgrass from last year.  But what about the thousands of seeds that are ready to germinate?  How do we stop them from popping up?

We all know a few things about how crabgrass grows, for instance …

  • Crabgrass is an annual plant that drops thousands of seeds for the next season
  • It favors low calcium and low organic matter
  • It thrives in low and high moisture settings
  • It loves compacted soil and clay areas
  • It tolerates salt and other toxins
  • It will germinate in low mowed grass
  • It will grow when soil temperatures are at 55 degrees or higher for 5 days straight

So if we do the opposite of what crabgrass likes, then we can eliminate it WITHOUT the use of harmful chemicals. 

Starting off the spring season with a high quality organic fertilizer is going to be key.  Adding nutrients and organic matter into the soil will relieve the stresses caused by the cold season.  On the other hand, applying high salt-based synthetic fertilizers will do more damage than good coming out of this Midwest winter.

Applying a product like BioGreen’s TurfMaster in the spring will thicken up the lawn while adding plenty of organic matter and nutrients back into the soil.  It contains calcium and humates to help relieve compacted soil and remove toxins.

Then, by raising the mower height to 3 inches, the crabgrass seeds can be shaded out, preventing them from even germinating in the first place.

Keep the right amount of moisture in the ground and you have a perfect recipe for a healthy lawn.

Don’t give crabgrass and other weeds a chance to start growing in the first place. has all the information you need to have a safe and healthy lawn.
