Key considerations

Walking down the pesticide aisle is overwhelming. You see rows of jugs promising to obliterate dandelions and crabgrass overnight. The reality is that choosing the right formula depends entirely on where those weeds are growing. Broad-spectrum formulas will clear a gravel driveway but destroy your lawn in the process. Selective herbicides target specific invaders while leaving your grass intact. Buyers should prioritize application methods and active ingredients over flashy marketing claims.

Spot Treating Your Grass

Dandelions and clover love to ruin a perfectly good lawn. You need a selective herbicide that kills broadleaf weeds without harming the turfgrass around them. Look for ready-to-use spray bottles for small patches. Concentrates make more sense if you have a massive yard. Always check the label to ensure it is safe for your specific grass.
