Controlling Ohio Lawn Weeds
Weeds in the lawn can be any plant that disrupts the uniform appearance of the green expanse created by your lawn. Not only do they usually disrupt this view, but they also are more aggressive in their growth, more aggressive in their consumption of soil nutrients and water supply. Healthy lawns will aggressively crowd out most weed seeds that germinate. Unhealthy lawns that are thin or week, are easy targets for weed seeds to take root and establish themselves.
Lots of weeds in a landscape are a good indicator that the soil may be in poor condition and maybe on a downward spiral that will become increasingly harder to support a thick turfgrass. As the soil becomes more compacted it makes it harder for moisture to penetrate down to the turfgrass' roots. Likewise, nutrients also find it harder to penetrate. The result: thinning lawns that allow for weed seeds to germinate and thrive.
Most weeds fall into two categories: broadleaf and grassy-type. Another division of lawn weeds are whether or not they are annual or perennial. Annual weeds are those that live for up to 12 months, and not necessarily 12 consecutive months. Some annual weeds will spout during the first season, and then return the following season to flower and re-seed.
Perennial weeds are defined as weeds that live for at least 3 growing seasons or longer.
Crabgrass is a warm season annual grass that has become widespread throughout Ohio. It grows best in the heat of midsummer. The plant cannot survive our cold winters, but its seeds do survive and in great number. Comes up about mid-May or late. Crabgrass can be controlled in a number of ways including our pre-emergent weed control. Perhaps the best defense against crabgrass is a thick vigorously growing lawn.
Dandelions are a broadleaf weed that is best treated during active growing cycle with a spot treatment. Dandelions have long taproots, which readily regenerate new plants when cut or damaged. We use a spot treatment that will not harm beneficial grasses. Dandelions are the most common weed to develop from tiny seeds that drift on the wind from neighboring lawns.
Plantain is broadleaf weed that is similar to dandelions. Its broad leaves and tall flower are easily identified. They are typically found in compacted soil areas where lawns have thinned out enough to allow them to take root.
Ground ivy, also known as Creeping Charlie, is hard to control and spreads quickly. Ground ivy spreads via creeping stems that propagate new plants. We have special controls that can control this weed. It may require repeated efforts.
