Catchweed: Identifying and Controlling This Annual Weed

Catchweed, also known as cleavers or goosegrass, is a cool-season annual weed that thrives in Charlotte's spring and fall. This distinctive weed has hooked hairs that cling to clothing, animals, and equipment—hence the name catchweed. Its climbing, weak stems sprawl across turf, and square cross-section stems distinguish it from true grasses. Catchweed germinates in fall and grows through winter and spring before dying in early summer heat.

Identification Features

• Weak, sprawling stems that cling to everything they touch
• Square cross-section stems (unlike round grass stems)
• Narrow leaves arranged in whorls around stem
• Small hooked hairs on leaves and stems that catch on clothing
• Yellow-green color distinguishing it from desirable grass
• Growth most vigorous March-May as temperatures warm

Control Methods

1. Manual Removal: Pull catchweed when soil is moist in spring, removing the entire weak root system. Small infestations can be hand-pulled completely
2. Post-Emergent Herbicide: Herbicides containing 2,4-D effectively control catchweed when applied in March-April during active growth
3. Pre-Emergent Herbicide: Fall pre-emergent applications in September prevent catchweed seed germination before establishment
4. Early Spring Treatment: Scout for catchweed by February and treat immediately upon detection. Early treatment prevents seed production
5. Seed Prevention: Never allow catchweed to flower and produce seed. Remove any flowering plants before seeds mature

Prevention Strategy

Catchweed prevention begins with dense overseeded turf that physically prevents seed germination. Fall overseeding at high rates (8-10 lbs per 1,000 sq ft) creates competition that suppresses catchweed. Thick spring turf prevents catchweed establishment as temperatures warm from dormancy.
