Lawn Weed Identification and Treatment Guide

Identify broadleaf and grassy lawn weeds including Crabgrass, Dandelions, Clover, Nutsedge, and Poa Annua with selective herbicide recommendations.

Broadleaf weeds (dandelion, clover, plantain) and grassy weeds (crabgrass, nutsedge, Poa annua) need different chemistry. Pre-emergents stop seeds; post-emergent selectives hit plants that are already up. Misidentifying nutsedge as a grass and spraying a crabgrass killer wastes product.

Use photos and descriptions in the weed ID tool, then match a labeled selective herbicide and the soil-temperature window for your region.
