Greenhouse

  • Clean out the greenhouse to get rid of debris that can harbour overwintering pests and diseases
  • Wash greenhouse glazing to let in as much of the weaker autumn daylight as possible
  • Bring potted tropical plants inside, including bananas, pineapple lilies (eucomis) and brugmansias
  • Plant hippeastrum (amaryllis) bulbs in pots on a warm windowsill for flowers by Christmas
  • Move potted citrus plants and fuchsias inside over winter, keeping them cool but frost free
  • Sow quick-growing microgreens for nutrient-rich pickings in just a few weeks, here's 10 microgreens to grow
  • Line greenhouse glazing with bubble insulation, as night-time temperatures start to drop
  • Keep indoor azaleas constantly moist, ideally using rainwater
  • Pot up the roots of lily-of-the-valley to provide fragrant winter flowers indoors
  • Water plants more sparingly as conditions turn cooler and the days get shorter
  • Sow sweet peas in deep pots for early flowers next summer
  • Force narcissus bulbs for fragrant indoor blooms in about 10 weeks
  • Spread out harvested onions and garlic on greenhouse staging to dry thoroughly before storing
  • Inspect plants you bring into the greenhouse over winter for any pests and diseases
  • Attach guttering to the greenhouse and install a water butt, to make good use of autumn rain
  • Clear fallen leaves from greenhouse guttering to ensure water butts fill up
