Central Ohio lawns deal with a consistent set of weed species year after year, and knowing which ones are present on your property matters for treatment. Different weeds require different approaches—pre-emergent versus post-emergent applications, broadleaf treatments versus grassy weed control—and misidentifying the problem leads to products that do not work. Our weed control services cover the full range of species found in Columbus-area lawns, treated at the right time and with the right products for each type.
Dandelions
Dandelions are the most widely recognized broadleaf weed in the region and among the most persistent. They develop deep taproots that make hand-pulling largely ineffective—the root typically breaks and regenerates. Each plant produces a large number of seeds that disperse easily by wind, meaning a yard with several dandelions can see a much larger population within a season or two if not treated. Dandelions are effectively controlled with post-emergent broadleaf herbicide applications timed to active growth in spring and fall.
Clover
White clover is common throughout Central Ohio lawns and spreads by both seed and creeping stems. It is frequently found in lawns with low nitrogen levels, since clover fixes its own nitrogen from the atmosphere and does not require fertile soil the way turf grasses do. A properly fertilized lawn is less hospitable to clover over time, but post-emergent broadleaf treatment is required to remove established plants.
Crabgrass
Crabgrass is a warm-season annual grassy weed that germinates in late spring when soil temperatures warm, grows aggressively through summer, and produces thousands of seeds per plant before dying at the first frost. Because it is a grassy weed, standard broadleaf herbicides do not control it. Pre-emergent application is the primary tool for managing crabgrass—it must be applied before germination occurs, typically in late March to mid-April in this region. Our existing post on how to get rid of crabgrass in your Columbus lawn covers this in more detail.
Ground Ivy
Ground ivy, sometimes called creeping Charlie, is a low-growing broadleaf weed that spreads aggressively by stem. It is particularly common in shaded, moist areas of the lawn and is one of the more difficult broadleaf weeds to control. It requires post-emergent treatment with products specifically effective against it, and repeat applications are often necessary. Fall is generally the most effective treatment window for ground ivy.
Nutsedge
Nutsedge is not a true grass or a broadleaf weed—it is a sedge, and it requires a different class of herbicide than either. It is recognizable by its triangular stem and bright yellow-green color, which stands out visibly against turf. Nutsedge thrives in areas with excess moisture and poor drainage, which are common conditions in Central Ohio’s clay-heavy soils. Standard weed control products typically do not affect it, which is why nutsedge often persists in lawns where other weeds are being managed.
Chickweed
Chickweed is a cool-season broadleaf annual that germinates in fall and overwinters as a low-growing mat, becoming visible and actively growing in early spring. It is commonly found in shaded and moist areas and is effectively controlled with broadleaf post-emergent treatment during its active growth period in early spring.
Why Identification Matters
A single lawn can have multiple weed species that require different treatment approaches and different timing. Applying only a broadleaf herbicide will not control crabgrass or nutsedge. Applying a pre-emergent too late misses the window for crabgrass prevention entirely. At Weed Busters, we identify what is present and build the treatment schedule around the specific weeds in your lawn.
