Roundup - our guide to garden weeds

Broadly speaking, the weeds you’ll see in your garden can be divided into four groups: perennial weeds that have deep roots and can be tough and persistent. They survive for many year is not treated; easier-to-shift annual weeds that die after releasing seeds that germinate and grow next season; woody weeds are stubborn perennials, designed to survive in difficult conditions. Finally lawn weeds that grow so quickly they can take over the grass.

Need help?

When can my children/pets use an area where Roundup has been applied?

The moment Roundup has dried. It deactivates on contact with soil, and is degraded by micro organisms leaving no residues in the soil.

Why has Roundup killed my lawn?

Roundup should never be used on lawns. Because it kills all plants with green leaf tissue, Roundup is actually a very effective grass killer.

When can I replant/reseed after treatment?

Immediately, if you want to. We recommend, however, leaving the weeds at least 7 to 10 days to absorb the optimum amount of Roundup.
