Usage Guidelines

Roundup Weed Barrier Granules is versatile but has its limitations.

  • Where Not to Use: The product is strictly not used on lawns, vegetable gardens, or plants grown for food/feed. It’s also not suitable for plants grown commercially or for research purposes.
  • Where to Use: It’s perfect for established trees, shrubs, perennials, ground covers, ornamental grass, bulbs, and bedding plants.
  • When and How Often: The best time to apply is in Spring before weeds germinate. Once applied, it protects for up to 12 months.

Safety First

The manufacturers recommend washing the granules from plants and activating the product post-application with a light water spray. Ensure that the granules do not stay on plant leaves.

If mistakenly applied, a simple rinse with water should suffice. It’s essential to note that the product should not be used in edible areas of your garden.
