Little Barley is like an unwanted guest at a party—it shows up when it's least expected. It forms clumps of grass with seed heads resembling miniature barley spikes. While it may not be the flashiest weed, it's persistent.

Clover - The Nitrogen Fixer
Alias: Trifolium
Clover may seem charming with its trifoliate leaves and white or pink flowers, but it's not always a welcome addition to your lawn. It's a nitrogen fixer, which can be beneficial in some cases but disruptive in others.
BATTLE PLAN: Hand-pulling and spot treatments with herbicides can control clover without harming your desirable grass.
In the battle against winter weeds, knowledge is your most potent weapon. By identifying these common culprits and implementing targeted control strategies, you can ensure your lawn remains green and healthy. Remember, a well-maintained lawn is not just a landscape; it's a canvas for countless outdoor memories.
