One application controls weeds for up to three months. OH2 has been tested for safety on over 100 ornamental crops. It is the safest and most reliable pre-emergent herbicide to apply to containerized plants.

Sierraron extends yours weeding effort- simply weed, and then apply Sierraron for 6 months protection from weed growth. It should be noted that Sierraron is not ideal for every situation. As Sierraron works close to the surface, it has little or no impact on deep-rooted and established trees, however Sierraron should not be used near young, recently planted or shallow-rooted plants and shrubs. Apply Autumn, Winter and early Spring when lower temperature conditions assist in Sierraron’s effectiveness. Please contact ICL for a tailored weeding program.
