We use a residual weed control with Glyphosate, to control weeds all year round.

This enables us to only need to apply two treatments a year to control all weeds on gravel surfaces for the complete year.

​

Residual weed control leaves a barrier on the surface treated to prevent new germination for a period of time, usually about 6-8 months per treatment, in standard weather conditions in the UK.

​

As for re-entry there is no requirement to restrict access to an area that has been treated with a mix of residual Weed Control plus glyphosate under normal usage conditions, by people, pets and wildlife. However it is recommended not to walk into areas where the spray could still be wet, as this could lead to transfer to other areas and damage to other plants and foliage.
