Greenhouse checklist

23 - 29 December 2013

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
