Product details

Effective Weed and Grass Control

Take command of your outdoor areas with the Roundup® Weed & Grass Killer4 Club Bundle. This powerful solution eliminates tough weeds and grasses right down to the root, including dandelion, chickweed, both red and white clover, poison ivy, spotted spurge, and other listed weeds. It's a reliable choice for maintaining a clean and weed-free environment in your garden or yard.

Fast-Acting and Rainproof

Roundup® Weed & Grass Killer4 is rainproof in as little as 30 minutes, ensuring that your weed control efforts aren't wasted even if the weather changes. It delivers visible results in just a few hours, so you can quickly see the difference it makes. You can also plant new flowers or crops 1 to 30 days after application, making it a convenient choice for gardeners (see booklet for details).

Versatile Usage

Use this weed and grass killer in flower beds, around perennial landscape plants, trees, and shrubs, or on patios, walkways, and driveways. It's also suitable for gravel or mulch beds, along fences and foundations, and for edging around foundations and retaining walls. For optimal results, apply during warm, sunny weather when the temperature is above 60°F.

Safety Instructions

Ensure the safety of people and pets by not allowing them to enter the treated area or touch treated plants until the spray has dried. This helps to prevent any potential skin irritation or other adverse effects.

Convenient Bundle

The Roundup® Weed & Grass Killer4 Club Bundle includes the continuous spray Comfort Wand® for easy application, along with two 8 fl. oz. concentrate refills. This ensures you have enough product to tackle a large area or multiple smaller areas, making it a cost-effective solution for your weed control needs.

Best weed killer

Best weed killer I have been using for years. I try to keep up with it every few weeks to make sure the weed doesn’t take over the lawn and garden. 🪴 highly recommend
