How Often Should You Apply Ortho Weed B Gon?

Ortho Weed B Gone works by penetrating the plant's leaves and travelling down to the roots where it kills the plant. If the product is applied correctly and in the right concentration, one application should kill the weed effectively.

Some Weeds Continue to Sprout All Season

Ortho Weed B Gone is only effective on plants that are already growing. Some weeds, like dandelions, go through multiple reproductive cycles over one season. If the seeds of such a weed have not yet sprouted, Ortho Weed B Gone will have no effect on that plant.

Bottom Line

Provided label instructions are followed carefully, Ortho Weed B Gone should be effective on individual weeds within one application, but additional applications may be needed for newly sprouted weeds.
