Greenhouse checklist

19 - 25 December 2016

It's time to...

  • Clear leaves from greenhouse gutters
  • Check heaters daily to ensure they are working efficiently and that fuel levels don't need topping up
  • Pick off dead flowers and leaves
  • Water overwintering plants such as pelargoniums sparingly
  • Wash glazing inside and out to let in more light
  • Take root cuttings of perennials including phlox and oriental poppies
  • Plant hippeastrum bulbs
  • Use rainwater to keep the compost of potted azaleas constantly moist
  • Ventilate greenhouses on warm, dry days
