Ortho GroundClear Super Weed & Grass Killer1 Refill — Fast-Acting, See Results in Hours, For Patios & Landscaped Areas, 1 gal

Fast, reliable weed control for patios, driveways, and landscape borders

Ortho GroundClear Super Weed & Grass Killer1 Refill is a ready-to-use solution designed to tackle a wide range of weeds and grasses. Its dual-action formula begins working on contact while also moving into the plant to target roots, helping you manage unsightly growth across multiple outdoor spaces. With the ability to target up to 175 weed types—including stubborn offenders like crabgrass, dandelion, nutsedge, and oxalis—you can protect problem areas with a single, convenient product.

How the formula works

• Dual action kills weeds on contact and travels to the roots for thorough control.
• Systemic action helps prevent regrowth by moving through the plant’s structure.
• Rainfast after 15 minutes, allowing you to plan around short weather windows.

What you can expect in real use

• Weeds usually wilt within hours, with complete kill typically in 1–2 weeks depending on weed type and growth stage.
• Suitable for patios, walkways, gravel, mulched beds, and along houses, fences, and other landscape features.
• Works where weeds hide, including cracks and edges along borders, driveways, and between hardscape areas.

The refill is designed to work with your existing Comfort Wand from an empty Ortho GroundClear bottle. Attach the wand holder to the refill, connect the hose until it clicks, and you’ll have a continuous spray setup that minimizes bending, pumping, or hand fatigue while you target weeds with precision.

Usage tips for best results: apply when weeds are actively growing and the air is calm to minimize drift. For landscape borders, patios, walkways, gravel, mulch beds, along buildings, and driveways, this refill provides a practical, all-in-one solution. Rain or watering within 15 minutes after application won’t reduce effectiveness, helping you fit treatment into your routine without fuss.
