Weed-opedia: Red Clover
Red Clover (Trifolium Pratense)
What does it look like?: Red Clover is similar to White Clover, but different in a few ways other than the color. It typically has more of an upright, mounding growth habit than White Clover. Look out for red/purple flowers which are surrounded by dark green clusters of 3 leaflets (signature of a clover).
What causes it?: Typically shows up in partially shaded areas with loose soil.
When does it show up?: Grows through Spring, Summer, and Fall.
Best treatment plan: Red Clover can be pulled by hand, but be careful not to spread any seeds. You may want to look into a selective herbicide, which targets clover cultivars. Call a professional for a free quote.
How long will it take to get rid of it?: Most homeowners struggle with this or other Clover varieties every single year. The best defense is just to make sure that you have thick turf and minimal bare spots.
