Crabgrass Prevention Options

March 2, 2018

If you love your lawn, you’ve gotta hate crabgrass. It’s an aggressive, stubborn weed. Even if you had just one crabgrass plant last year, your lawn could have thousands of crabgrass seeds lying in the soil right now ready to grow up and choke your good grass to death.

This photo of a mature crabgrass plant appeared in a Scotts publication about 20 years ago. The caption: “A single seed produced this monster crabgrass plant, which crowded out good grass as it grew. Each plant is capable of producing tens of thousands of seeds for an even bigger problem next year.”

I have good news. You can stop crabgrass and several other kinds of annual weeds before they begin to grow this spring. Put down some Turf Builder with Halts Crabgrass Preventer around the time of your first mowing. This product does just what its name says: halts crabgrass in its tracks by creating a barrier on your soil that stops it from germinating. Plus it gives your good grass the deep Turf Builder feeding it needs to green up and create new roots this spring. Unlike the bargain brands, the particles are tiny, which means you get a good weed barrier on every inch of your lawn.

If you have a Kentucky Bluegrass, Perennial Ryegrass, Tall Fescue or Fine Fescue lawn and you want to control dandelions and other weeds with the same application that prevents crabgrass, there is a new product for you: Scotts Turf Builder Triple Action. Apply after dandelions begin to flower when your temps are regularly hitting the 60’s to a moist lawn when no rain is expected for 24 hours. Water your lawn after 24 hours to help the granules contact your soil.

If you plan on putting down some grass seed this spring, you need to use a different crabgrass preventer that will not keep your new grass from growing. Instead, use Turf Builder Starter Food for New Grass plus Weed Preventer as it is compatible with grass seed and has the special food to help you get new grass faster.


You should apply your crabgrass Preventer by the time forsythia bushes in your neighborhood have stopped blooming and lost their flowers, or if you do not have forsythia, by the time you see lilacs in bloom, or before you start seeing dandelion puffballs.
