Best Weed Killer for DIYers
Weed killers (herbicides) clear unwanted growth from lawns, beds, driveways, and gravel. The key distinction is selective (kills weeds, spares lawn grass) versus non-selective (kills everything), plus chemical versus natural options. Always read and follow the label.
What to look for
- ·Use a selective lawn weed killer to spare grass, and a non-selective killer for driveways, gravel, and total clearing (it kills everything it touches).
- ·Natural options (vinegar/acetic acid, fatty acids) work on contact for small areas and are pet- and kid-friendlier once dry, but may need repeat applications.
- ·Always read and follow the label for rates, safety, rain timing, and re-entry; wear protection and keep kids and pets off until dry.

Frequently asked
Selective or non-selective weed killer?+
A selective herbicide (like a lawn weed killer) targets broadleaf weeds while sparing your grass, for use on lawns. A non-selective herbicide kills nearly any plant it contacts, for driveways, gravel, fence lines, and total clearing, not for use on a lawn you want to keep. Match the product to whether you are protecting grass or clearing everything.
What is the best weed killer for a driveway?+
For driveways, gravel, and cracks, a non-selective vegetation killer (which often also prevents regrowth for months) is the go-to, since you want to kill everything there. Natural high-strength vinegar products also work for contact kill on small areas. Always confirm the product is safe for the surface and nearby desirable plants.
Are natural weed killers effective?+
Natural weed killers (industrial-strength vinegar/acetic acid, or fatty-acid products) burn down the tops of weeds on contact and are effective on young, small weeds and for spot-treating, and they are pet- and kid-friendlier once dry. They may not kill deep roots in one pass, so established perennial weeds often need repeat applications.
How do I apply weed killer safely?+
Read the label first, wear gloves and eye protection (and follow any clothing guidance), apply on a calm, dry day to avoid drift onto desirable plants, and respect rain-free and re-entry times. Keep children and pets off treated areas until dry (or as the label states), and store and dispose of it properly.
When should I apply weed killer?+
Apply to actively growing weeds on a warm, calm, dry day with no rain expected for the period the label specifies. Selective lawn products work best on young, actively growing weeds in spring and fall. Pre-emergent products are applied before weeds sprout. Timing to the weed's growth stage greatly improves results.
