Month by Month Gardening Calendar - 12 December

What to do in the garden in December
December is a good month in the garden for maintenance, there can be some beautiful clear and crisp days, so make the most of them when they are here! These kind of days are the perfect time to get any fence or shed repairs done - if you haven't cleaned your greenhouse yet this is also a good time to do so. There may not be as many daylight hours but that doesn't mean you can't still enjoy being out in the garden when the weather is lovely.

Unfortunately, we can also expect much colder, rainier weather and sharp, chilly winds this month, so make sure to protect any plants that are susceptible to frost. For pots likely to suffer from water-logging and drainage issues raise them up by placing pots on pot feet or bricks.

For the days when the weather is less than favourable, you could use this time to gain inspiration and create a garden project plan for next year. Think about what grew well in the garden this year and which plants you would like to grow next. 

Take a look at our list of jobs to do in the garden in December below. 

Ornamental garden:
  • Keep borders tidy by removing any debris, leaves etc.
  • Check newly planted shrubs for wind rock (loosened soil around the base) after strong winds.
  • Prune woody ornamental plants but avoid when frost or snow is forecast.
  • Mulch if the weather is still mild.
  • Shake off snow from hedges and shrubs to avoid damage.

    Other jobs:
    • Insulate outdoor taps and pipes to avoid them freezing.
    • Ventilate the greenhouse on mild days.
    • Protect plants and pots likely to be affected by frost damage.
    • Hang fat balls and ensure bird-feeders are well stocked.
    • Make sure compost bins/heaps are covered to prevent them from becoming soggy.
    • Turn compost bins to ensure full decomposition.
    • Ensure houseplants are getting enough light indoors by placing them on a sunny window sill.
    • Keep clearing remaining plant debris and leaves.
