Weed-opedia: Ground Ivy
Ground Ivy (Glechoma hederacea)
What does it look like?: Creeping square-stemmed vine. Green kidney-shaped leaves with scalloped edges. Small, bluish purple flowers.
What causes it?: Shady, wet soil.
When does it show up?: Early spring.
Best treatment plan: Hand-pulling small infestations works, but can be tedious due to the small roots along the stem. Spring and fall post-emergent herbicides in combination with creating conditions that are less favorable (i.e. better drainage and more sun) work best. Call a professional for a free quote.
How long will it take to get rid of it? Probably a year of consistent effort.
