Catchweed Bedstraw: The Sticky Weed
Catchweed is easily identified once you know the telling characteristics. It goes by many other names such as cleavers, bedstraw, stickywilly, and velcro plant. As these names suggest, it's sticky! It can be found almost anywhere but prefers moist, shady spots. It is mostly found in disturbed areas such as waste piles, ditches, and roadsides. Although, we have seen this weed in many lawns in middle Tennessee.

What does catchweed bedstraw look like?
Catchweed bedstraw tends to grow along the ground creating a dense tangled mat over whatever vegetation it surrounds. Walk through a patch of catchweed, and it will stick to you and your clothes. Why? The small leaves, which are generally 1/2 to one inch long, are spiral and have downward-curved prickles that cover the stems and leaves. The prickles are responsible for the sticky nature of this plant and aid in seed disbursement. The stems can grow up to 6 feet long! The flowers can also aid in identifying catchweed. They are small, four-parted, and are either white or greenish-white.
How can you prevent catchweed bedstraw?
Like many other weeds, catchweed bedstraw can be both a winter annual and a summer annual, which means year-round control is necessary. Seeds that are up to three inches deep in loose soil have been known to germinate and sprout, so this weed is hearty and will definitely compete for nutrients and water. Be sure you are practicing great lawn maintenance to ensure the healthiest turf so grass will win the battle! Pre-emergent treatments are effective, but they must be applied in spring and fall.
