Weed tips

  • If your lawn is beyond redemption, or in dire need of repair, now is the time to do it, while days are mild but there is enough warmth in the sun to promote rapid growth. If required, kill the existing lawn fully with Roundup. Wait for at least a week (until it is obvious the grass is dying) before cultivating and preparing the soil either for sowing seed or laying turf.

Garden maintenance in September

  • Plant evergreen trees and shrubs, including hedges. Be sure to water regularly if the weather is dry
  • Plant early potatoes
  • Lift and divide overgrown clumps of perennials that weren’t lifted in autumn
  • Clip lavenders after the first flush of flowers
  • Start mowing the lawn regularly, and raise the cutting height to leave the grass a little longer – that will protect the roots from the sun
  • Plant summer flowering bulbs – gladioli will bloom about 60 days after corms are planted
  • Sow seeds of summer annuals like French and African marigolds, petunias and nicotianas
  • Prune climbers and plant new ones

What are the origins of Roundup?

A Click here for the answer

Roundup was first developed for the agricultural industry to help farmers overcome large-scale problems with weeds. This same science and technology has been applied to create a range of weed killing products ideal for domestic use. So, rest easy in the knowledge that you’re using the weed killer the professionals use.


Can I put it on stronger? Will that work better?

We have carefully calculated the best rates at which to apply for each type of weed problem. Applying at a strong rate is not recommended and will not result in better performance. Please ensure that you read the label before use and use pesticides safely.


Does the Concentrate need using up straight away after mixing?

It’s always good practice to only mix up what you need for that treatment, but you can retain the unused solution for up to a week, since a gradual loss of activity will occur. Make sure that you store any weedkiller safely away from the reach of children and pets.
