How to apply weed killer to lawn?

Proper Weed Killer Application

Effective weed control requires understanding herbicide types, application timing, and proper technique. Selective herbicides target specific weed types; non-selective products kill all vegetation. Proper application ensures maximum efficacy while minimizing environmental impact and drift to non-target plants. Application errors reduce effectiveness and potentially damage desirable turf.

Weed Killer Application Guidelines

1. Product Selection: Choose selective herbicides for broadleaf weeds in grass or non-selective for complete vegetation removal. Read labels for target weeds and application restrictions.
2. Timing: Apply when weeds are actively growing (spring and fall) with adequate soil moisture. Avoid application before rain or extreme heat.
3. Lawn Conditions: Mow 2-3 days before application. Slightly wet foliage helps herbicide adherence. Avoid mowing for 3-5 days after application.
4. Application Equipment: Use backpack or handheld spray equipment with 40-50 PSI pressure. Calibrate equipment to apply appropriate rates—too little is ineffective, too much wastes product.
5. Coverage: Ensure thorough coverage of weed foliage without creating excess runoff. Apply during calm conditions to minimize drift.
6. Post-Application: Keep people and pets off treated area for 24-48 hours. Water after herbicide dries (typically 4-6 hours) to activate some products.
