Weed tips

  • Weeds emerge in many, often awkward or inconvenient, places as the soil warms in Spring. Spot spray with Roundup but avoid spray drift on to surrounding ornamentals. Avoid disturbing the soil and keep a good depth of mulch over beds to reduce the potential for other weeds to emerge.

Garden maintenance in October

  • Prepare for Summer by adding 8-10cm of mulch over garden beds now
  • Remove spent flower heads from spring bulbs, leaving the leaves intact for at least six weeks (preferably allow them to die down naturally) and feed with Osmocote Garden Beds to promote good bulbs for next season
  • Sow seeds and plant the first of the summer vegetable crops, including tomatoes
  • Cut back straggly evergreens to encourage new growth from base
  • Reseed bare patches on the lawn if you didn’t do so last month
  • Plant evergreen trees and shrubs
  • Stake tall growing perennials
  • Cut old foliage from ornamental grasses and ferns
  • Clean the pond, start feeding summer foods to your fish and plant new aquatic plants

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.
