Weed Control

As the old saying goes, an ounce of prevention is worth a pound of cure. One of the best ways to thwart weeds is by applying a pre-emergent weed killer. A pre-emergent is an herbicide that kills weeds before they even have a chance to sprout. The first step in weed prevention is to identify which kinds of weeds are likely to invade your lawn. Lawn weeds are generally broken down into two groups: Grassy Weeds and Broadleaf Weeds.

Grassy Weeds are nothing more than types of grasses that you don’t want in your lawn or flower beds. They can be either annual grasses like crabgrass or perennial grasses like fescue. An easy way to tell which kind of weed grass you have is to observe when it turns green. Perennial grass will green up early, at the same time as the rest of your lawn. Annual grass won’t appear until later in the season, around May.

Broadleaf Weeds are all other weeds that are not grasses. They are usually easy to spot, as they’re wide leaves stand out against they narrow leaves of grass. Broadleaf weeds include repeat offenders like dandelions, chickweed and spurge.

At O'Toole's Garden Centers we have a number of preventative products that will make sure that the only thing growing in your yard is stuff that you want growing in your yard.

Season Long Weed Control

Bayer Season Long not only kills tough broadleaf lawn weeds like dandelions, it also prevents new weeds from sprouting for up to 6 months. Apply in spring for a beautiful lawn all summer long.  Season Long provides both pre- and post-emergent control of both grassy and broadleaf weeds including dandelions, crabgrass, chickweed and clover. Systematic action from the leaves down and the roots up inhibits cell division and disrupts photosynthesis.
