Using weedkillers
To save time and hard work, weedkillers are the answer for anyone who doesn鈥檛 mind using chemicals.
  • Read the manufacturer鈥檚 instructions to be sure you are using the right weedkiller for the job.
  • Keep weedkiller off plants that you want to keep.
  • Dissolve/dilute the weedkiller according to instructions on the packaging and apply weeds using a fine rose (sprinkler head) on a watering can which you only use for weedkiller.
  • Don鈥檛 apply on a windy day because weedkillers can drift onto other plants.
  • The most effective time to apply weedkillers is when weeds are leafy and growing actively, mid-spring to early summer is ideal.
  • Keep weedkillers in a safe place, out of reach from children and pets. When empty, dispose of them carefully. Not all weeds will die so repeat applications may be needed.

Tackling an overgrown path
If you want to clear a neglected garden path overgrown with weeds, here鈥檚 how:
  • Chop everything down to say 10cm (4in) above ground level, rake up the bits and dispose of them.
  • Dig over the area and remove all the roots. Don鈥檛 hire a rotavator because this will chop up and spread perennial weed roots far and wide, making the weed problem much worse.
  • If you don鈥檛 fancy digging, wait until new weed shoots appear and apply weedkiller containing glyphosate.
  • Alternatively, cover the ground with sheets of black plastic or old carpet. Emerging weed shoots won鈥檛 get any light and will starve. This may take a couple of years to be 100 per cent effective.
