Summer Weed Control

Here are some of the most common weeds that plague our lawns through the summer season:

Annual Bluegrass

• Light green, cool-season annual grass
• Bunch type or ‘clump’ growth habit
• Numerous seeds, especially in spring, making it very noticeable in the lawn
• Dies out during the heat of the summer
• New seeds begin germinating late summer
• Found throughout the U.S.
• Apply crabgrass preventer before annual bluegrass begins germination in late summer


• Very common in new lawns
• Sprouts and grows in cool weather


• Often indicates poor soil, need for fertilizer (See our Jonathan Green fertilizers)
• Appears in cool weather


• Seeds sprout in spring and summer after rain or watering
• Very fast growing
• Likes bare and weak areas of the lawn

Creeping Charlie

• Extremely persistent
• Invasive, forms a mat that chokes and shades grass
• Most prevalent in moist soil and partial shade, but also thrives in sun


• Persistent
• Appears in early spring and continues through summer and fall, or year-round in warm climates
• Will adapt height to escape mowing


• Makes a mat that chokes lawn
• Likes rich soil
• Spreads quickly from seed

One of the most prevalent, widespread, and problematic of these summer weeds is Crabgrass. Bayer®  offers some products that work extremely well to rid your lawn of crabgrass and other broadleaf weeds that have already begun to take over your lawn.
