Garden jobs for December.

  • Flowers.

    Rake up accumulated fallen leaves in borders that could be harboring slugs and other pests.

    Plant bare-root roses, other deciduous shrubs, and ornamental trees.

    Move plants in pots to a sheltered spot if conditions turn very cold, as their roots are more exposed to the elements.

    Prune climbing roses between now and February.

    Hard prune overgrown shrubs and hedges while they're dormant.

    Check stored bulbs and corms regularly for any signs of rot.

  • Produce.

    Winter prune large fruit trees to control their shape and size, and to increase their productivity.

    Plant fruit trees trained as cordons, fans or espaliers to make good use of limited space.

    Start to plan next year's crops and order seeds.

    Lift and divide large clumps of rhubarb, replanting the outer sections into soil enriched with well-rotted manure.

    Finish clearing old crops and debris from the vegetable plot. Only compost healthy material.

  • Garden maintenance.

    Put out fresh water for birds every day during frosty weather.

    Bring all watering equipment indoors, including hoses and sprinklers, so they don't freeze and split.

    Scoop fallen leaves and debris from ponds, leave on the side so pondlife can escape, then add to the compost bin.

    Clear out your shed, and organize and clean your tools.

    Dig over bare areas of ground, incorporating garden compost.

    Check tree ties and stakes are firm enough to stand up to winter storms.

    Order well-rotted manure or mushroom compost to dig in over winter or spread over bare soil for worms to take down.

    Order summer-flowering bulbs such as lilies and gladioli.

  • Sow seeds.

    Cyclamen

    Lathyrus odoratus (sweet pea)

    Laurentia (blue star creeper)

    Pelargonium
