Give a last Roundup weedkiller spray to weeds

Roundup Weedkiller - Spray goodbye to summer

As the warm summer months give way to the cooler climes of autumn, don’t forget to give any weeds one last spray.

Looking after your garden, and keeping it looking its very best, is an ongoing exercise, with a constant battle being waged against weeds and unwanted vegetation. Given the right conditions, many weeds will grow all year round, with some, such as groundsel and common chickweed, having very short life cycles that can complete as many as five or six times every year.

So, as well as letting thoughts turn to spring, with the planting of daffodil and crocus bulbs, it’s also an ideal time to give any lingering weeds a spray of Roundup.

Roundup has a specially formulated action that will penetrate right down to the root of the weed, killing it outright and making sure it never comes back.

Moreover, with our wide range of ready to use products, it’s easy and convenient to target individual weeds growing in your garden – making sure the treatment goes exactly where you intended for it to go, and not on to any valuable surrounding cultivated plants.

Then, safe in the knowledge that you’re on top of any weed problems, you can get on with all those other end of summer and autumnal garden tasks – like building up your compost heap and raking back the dead moss and grass in your lawn.

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..
