Dicot Weeds

In a universe of hundreds of dicot weeds, a limited number can tolerate repeated mowing of managed turf sites. In order to provide a broader representation of turf weeds, we have included a select number of these dicot weeds. Those presented herein were chosen for their ability to survive in turf; often as a continuing pest. Several of the species can persist even at fairly short mowing heights; others are active in cool weather.

Identifying a dicot weed

Unlike the prototypical size and shape of monocot weeds, the shape and vegetative growth habits of many dicot weed m groups are visually unique. Also, the distinctive traits of monocots - seedheads, ligules and collars - are not always present, making visual identification more important.

We suggest the following process for identifying dicot weeds:

Look for a sample flower if available

Leaves: check for identifying characteristics (size, shape, notches, venation or coloration)

Stems: check how the leaves are held (opposite or alternate), shape and color

Flowers: check color, size and composition (single, double or compound)

Location: take note of the conditions in which the weed is growing (shade, compacted soil, etc.)

Distribution: confirm that this weed species has been identified in your state
