Description: resembles orchard grass, forms in patches, side branches w/ wide leaves that branch out in a star shaped pattern
Peak Season: Summer-annual grass (July – August)
Treatment: Pre-emergent herbicide to prevent germination
Crabgrass begins with a single shoot that grows side branches and then extends out forming a star shape. Recognized by its wide leaves and blades, crabgrass also forms in patches in your lawn
When will I see Crabgrass?
Crabgrass is an summer annual weed, meaning it grows seasonally, namely during the summer months. We start to see crabgrass in the cracks of the roads and sidewalks in June, which is an indicator of possible growth in your lawn a few weeks later (peaking from July – August).
How do I get rid of Crabgrass?
There is not a selective herbicide that kills existing crabgrass and not your lawn. If you already have this noxious weed, the only way to get rid of it is by hand. Because its a summer annual weed, it will only last for the season, and if properly prevented, will not plague your lawn for years and years.
How do I prevent Crabgrass from infiltrating my lawn?
There are a few things you can do to help prevent new growth in your lawn. These include:
- A Pre-emergence herbicide in April or May to help prevent germination.
- Mowing your lawn on the second highest setting to help crowd out any potential growth and block out the sunlight.
