Patience is Best When Preventing Crabgrass


Crabgrass is one of the most challenging annual grassy weeds to keep out of the lawn, especially in summer during its aggressive growth. Crabgrass, goose grass and foxtail are annual summer weeds germinating in spring when soil temperatures are consistently above 55°F, developing seeds in July, and killed by fall frost. A mature crabgrass plant can produce up to 700 tillers and 150,0000 seeds. 

Patience is best when it comes to preventing crabgrass. PREVENT! creates a barrier on the soil to kill crabgrass seeds before they mature. This vapor barrier is effected by UV light and will last ten to twelve weeks on the soil under normal weather conditions. Ugly annual summer grassy weeds love the heat. If applied too early in the season, a lapse in effective crabgrass prevention during late spring months may occur.

Recommended application dates for PREVENT! are mid-March to mid-April, most years it will be well in to April. Extend PREVENT! coverage longer into the weed growing season by having patience. Wait til ground soil temperatures are nearer to 55°. Watch the weather, when day and night time temperatures are above 50° for more than a week.

Keep Calm Feed On! The weather may give you the urge to get a head start on those ugly summer weeds, but be patient.  Crabgrass and other summer annual grassy weeds invade a lawn often because growing conditions favor the crabgrass and not the good turf. Improving growing conditions for the turf will help it out compete crabgrass and other weeds. Crabgrass and other annual grassy weeds are not controlled with WEED and FEED. . Broadleaf weeds are not controlled by PREVENT!

Feed your lawn in early March. If you have that early spring lawn fever, feed your lawn with GOLF COURSE STARTER or RENOVATOR. A thick lush and green lawn make it difficult for those ugly summer weeds to find room to grow in your lawn this summer. Eliminate the bare spots and you will eliminate the weeds.
