When should herbicides be applied?
Pre-emergents are usually applied in late winter or early spring, while post-emergents are applied in spring after the weeds begin to grow. When using herbicide in gardens, take care to protect the plants you don't want to kill.
How often should you spray herbicide?
The frequency with which you can apply Ortho weed killers is typically limited to two applications per year – a primary application followed by a second application shortly thereafter to eradicate any stragglers or persistent weeds.
Does Roundup kill trees and shrubs?
Selective herbicides target certain types of weeds such as broadleaf or grassy weeds. In use since 1974, Roundup (glyphosate) is a non-selective herbicide that kills most weed species. It can also kill your shrubs if it accidentally gets on them while you're waging the weed war.
How long does Roundup stay active in the soil?
