How do I get rid of Crabgrass?

Crabgrass is going to be on everyone’s minds shortly.  Spring is around the corner, and that means it almost time for the big green up. One of the biggest concern lawn care customers have is controlling weeds in their lawns.  Some types of weeds respond better to treatment after they emerge from the ground, but others respond to treatment before they germinate hence the term pre-emergent.  For weeds like crabgrass and spurge, a pre-emergent treatment is the best way to prevent them from coming into your lawn.  A crabgrass pre-emergent is included in our hybrid lawn fertilization package.

This is a picture of young crabgrass in the middle of June – the small lime green sprouts are the crabgrass.

EcoTurf wants to stress the importance of your first application of fertilization with a pre-emergent for weeds like crabgrass and spurge in our hybrid lawn fertilization program.  EcoTurf uses a carefully thought out and proven effective combination of organically derived nutrients which allows for the significant reduction of synthetic additives like nitrogen, herbicides, and insecticides.  You get all the green and lush effects, without all the harsh chemicals. 

EcoTurf offers the benefits of a pre-emergent control of crabgrass in our hybrid program.  We recommend applying the pre-emergent with the first round of fertilization between March and April since the crabgrass will usually germinate in Colorado in May or June.  We want to stress the importance of regular fertilization, frequent irrigation, and carefully mowing your turf to the highest mower height, in order to create the healthiest turf possible.  These cultural practices will allow your grass to be naturally more healthy which aids in weed suppression.

In some instances, crabgrass still can be a problem in some lawns so we offer post-emergent control for crabgrass after germination if breakthrough occurs. You can see below the light lime green crabgrass along the edge are clearly different than the other grass types.

Crabgrass tends to be the catchall for unwanted grasses in lawns. Below is picture of mature Crabgrass in July. There are many “undesirable” grasses but Crabgrass is much lighter green than regular grass types.
