Sierraron 4G is an extra resource for weed control to be used in conjunction with current weed management systems. 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.

Ideally, it should be applied in Autumn, Winter and early Spring when lower temperature conditions assist in Sierraron's effectiveness.
