Classifying Weeds

To effectively manage weeds in your Florida lawn or garden, it's important to know the different types of weeds. Something that controls one type of weed may not control another type. There are three general groups of weeds: broadleaf, grassy, and grass-like (sedges).

Broadleaf weeds, like clovers and beggarweed, have leaves with net-like veins and usually have showy flowers. Grassy weeds look like grass, and include goosegrass, crabgrass, and smutgrass.
Sedges, like purple nutsedge and water sedge, have triangular stems, often have soft, burr-like seed heads, and prefer moist habitats.
