Getting a Handle on Crabgrass in Southern California

There is something here that homeowners share with those across most of North America.  Crabgrass is the bane of residential lawns, despite being the right shade of green.  This coarse, spreading weed loves the heat and drought that is so typical of our summers.

Smooth crabgrass is the most common variety seen in Southern California and, if left to grow, can spread quickly and take over large patches of a lawn area.  Fortunately, there are a number of ways to make your lawn a place where crabgrass doesn’t stand a chance.

A Healthy lawn:  Ensuring that your lawn can put up a fight is the first line of defense against crabgrass.  Lawns need to be watered regularly, kept at an optimal height (not too low), and fertilized to encourage good root growth that can overtake those of the crabgrass and other emergent weeds.  Deep and infrequent waterings are best for turfgrass in our region.  Keeping lawns at about 3” high will block the sunlight crabgrass needs to grow and thrive.

Treatments:  A pre-emergent herbicide in the spring is effective in proactively stopping crabgrass from spreading.  Once the lawn has been treated, leave it for a while to make sure it has time to work its magic.  And save overseeding, aerating, and dethatching until fall, well after crabgrass is inclined to reseed itself on exposed soil.  If crabgrass has already established itself in your lawn, it can be treated with targeted post-emergent weed control methods such as hand-pulling, raking it out, and chemical weed control products.

Get ahead of it:  Crabgrass will die back in the cold weather, so use the winter months to get a plan of attack for next season. Consider enlisting the help of a landscape professional who can prescribe a good program for lawn care and pre-emergent weed control.
