The Weed Roller is very similar to the Wick Weeder but uses a ball to roll over the weeds. Fill the tube with products such as RoundUp or Horticultural Vinegar, go to the area you would like to treat, open the valve and start rolling. The valve allows you to control the amount of product that comes out.
The Weed Roller is a roll-on herbicide applicator with no chance of spray drift.
