Pests & diseases

  • Keep snails and slugs away from bulbs, annuals and clivia with animal-friendly pellets like Multiguard Snail & Slug Killer (use as per packet instructions).
  • Check indoor plants for scale infestation and treat with PestOil.
  • Spray fruit trees such as apricot, plum, peach and nectarine for brown rot with lime sulphur. Remove diseased leaves and fallen fruit.

General garden care

  • Lift dahlia tubers from the ground and store them in a dry position in a cool airy shed for replanting next season.
  • Treat the soil around your hydrangeas if you want to change their colour. Apply lime for pink shades or Hydrangea Blue for blue shades - it's much too late when flowers start budding in December.
  • Collect fallen autumn leaves and add to your compost bin. They're a great source of nutrients for your garden!
  • Divide strappy-leaved plants such as agapanthus, clivea, liriope and iris that have started to bunch and look messy. It’s a great time to dig them up, divide them and replant in an orderly fashion.
  • Now’s the time to ward off nasty winter grass. This weed seeds in autumn, winter and spring, then dies off in summer heat. Left untreated, it’ll weaken your lawn and result in more winter grass next season. As soon as you notice winter grass, spray with a selective weed control like Amgrow Winter Grass Killer.
