Speed and performance

Roundup is a deceptively fast worker.

After initially spraying Roundup on to a weed, you might be forgiven for thinking nothing much is happening, apart from some visible yellowing of the leaves and stem after 48 hours.

But, that’s just on the outside. On the inside of the weed, nothing works faster than Roundup. The systemic action takes Roundup right down to the weed’s growing points and, put simply, kills the weed from ‘inside out’.

Most importantly, of course, because Roundup kills the roots, you can rest easy knowing the weed’s not coming back.

Frequently asked questions

When can my children/pets return to the treated area?

When Roundup has been absorbed by the leaf, the residue will dry. When the residue has dried, children and pets can be allowed back onto the treated areas.

Can Roundup kill Japanese Knotweed?

Yes, but you will need to use Roundup Tree Stump & Root Killer. It may take several applications – please read the label for further advice.

When can I replant/reseed after use?

Roundup is only active in plants and is inactivated on contact with the soil. It is then broken down by soil micro organisms so that you can re-use the soil for re-planting. We recommend that you leave treated weeds for about 7 days before digging or cultivating the soil to allow Roundup to move to the roots of the weed.
