Nimblewill (Muhlenbergia schreberi) is a stubborn perennial weed that often invades lawns and gardens, causing an unsightly appearance. Killing nimblewill can be a challenging process, but with the right knowledge and tactics, you can eliminate this weed from your yard. Here are nine steps to help you rid your lawn of nimblewill effectively:
1. Identify the Nimblewill: Before taking any action, ensure that the weed you’re dealing with is indeed nimblewill. This weed has thin, wiry stems and produces a dense mat of fine-textured leaves. It thrives in shady areas but can also survive in full sun.
2. Mow Your Lawn Regularly: Maintain a regular mowing schedule for your lawn. Cut the grass at a height of 3 inches to encourage healthy grass growth and prevent nimblewill from spreading further.
3. Water Deeply and Infrequently: Over-watering or shallow watering can promote nimblewill growth by creating a damp environment perfect for its survival. Instead, water your lawn deeply once a week to encourage strong, deep-rooted grasses that will resist nimblewill invasion.
4. Apply Pre-Emergent Herbicides: Early spring is the best time to apply pre-emergent herbicides, as they prevent seed germination for various weeds, including nimblewill. Follow the application instructions on the product and repeat as necessary.
5. Use Selective Post-Emergent Herbicides: For established nimblewill patches, use selective post-emergent herbicides that specifically target this weed species without harming your lawn grasses. Apply during early morning or evening hours when temperatures are cooler for optimal effectiveness.
6. Hand Pulling: If there are only a few small patches of nimblewill in your lawn, you can hand-pull these weeds. Be sure to remove the entire root system to prevent regrowth, and discard pulled plants in a sealed bag or container.
7. Smother the Weed: Cover nimblewill patches with a dark, light-blocking tarp or multiple layers of newspaper. Keep these coverings in place for several weeks until the weed dies due to lack of sunlight.
8. Solarization: For large infestations of nimblewill, use solarization as an alternative method. This technique involves covering an area with clear plastic during the hot summer months, effectively using the sun’s heat to destroy weeds and their seeds beneath the soil surface.
9. Reseed the Affected Area: Once you have removed or killed nimblewill, consider reseeding your lawn to fill in bare areas where the weed was growing. This will prevent future invasion by opportunistic weeds.
By following these nine steps, you can effectively eradicate nimblewill from your lawn and maintain a healthy, weed-free yard that will look great all season long.
