Crabgrass Management is achieved in partnership with you, over several seasons to reduce this ugly, aggressive and invasive weed grass that occupies an otherwise beautiful lawn. Crabgrass seeds can blow in from neighbouring yards or fields and remain dormant for many years.
They wait patiently until your lawn has a moment of weakness (examples: drought, heat stress, or the time you mowed too short!). Only when these seeds receive the right amount of sun, moisture and contact with soil, then they will germinate and fight for space. They are annual plants that propagate themselves by releasing hundreds to many thousands of seeds each year from each individual crabgrass plant, as they die off each fall.
Who needs it?
Customers will recognize crabgrass in their lawn by its distinctive low growing habit, wide leaf blades and seed tillers. Often people will confuse it with Tall Fescue or Quack Grass
Turns purple in the fall.
Usually located near curbs and driveways as the seeds blow in from neighbouring properties.
Normally occurs in older more established neighbourhoods and lawns
There are 2 ways to attack crabgrass:
Crabgrass treatments are classified as “Pre-emergent” with corn gluten and “Post-emergent” by hand pulling.
Pre-emergent can only be done in the spring before the seeds germinate.
Treatments normally need to be made for several years to provide any measure of reduction for this persistent grassy weed. It can not be eliminated and is not guaranteed.
A healthy, thick lawn mowed at the correct height, and regular deep watering to prevent stress is the best defense against crabgrass.
Crabgrass is invasive and will spread through a lawn, eventually crowding out desirable grasses. Treat as soon as you can by hand-pulling.
LawnSavers can help reduce crabgrass in your lawn over the years and work with you to reduce its re-occurrence through proper lawn management.
Our spring treatment targets the entire lawn and not just the specific areas that crabgrass is growing and/or tends to grow.
Spring Pre-emergent Corn Gluten treatment in the spring helps to reduce seeds from germinating in the first place by creating a protective barrier on the soil that reduces seed germination. (up to 40% less germination over 2-3 years)
You must not rake or disturb the soil after application. (over-seeding is not recommended until fall)
Post-emergent treatment involves your partnership in pulling plants before they go to seed, and mowing with a bag attachment to reduce spread of the seed.
