Kerb® Flo is a residual herbicide that can be used as a pre or post-emergence weed killer in forestry and amenity plantings. It is predominantly used to kill grass weeds, but can also control troublesome weeds such as chickweed, cleavers, bindweed, fat hen, and will offer some control against horsetail.
Kerb® Flo can be used on ornamental shrubs, roses and is also widely used near trees and hedges. As it is mobile in the soil, it is important to apply it in cooler conditions (the soil temperature being cooler than 8 degrees) and when there is plenty of moisture. This best time for this is usually between November & January.
We have this product available as a spreadable granule which can be easier to apply. If this interests you take a look at
