December focus: Festive pot plants

Now the routine gardening has scaled down outside, it’s time to start decorating inside with some festive pot plants.

Poinsettias are a Christmas classic. With their bright red flowers, they fit perfectly into the traditional seasonal colour scheme. They also make striking centrepieces for your Christmas dining table.

Delicate in nature, poinsettias are sensitive plants. With a little care and attention they can continue to look great throughout the holiday season. Learn all about caring for a poinsettia with our easy to follow guide.

Garden jobs for December

General garden jobs

  • Carry out winter digging or forking over if the soil is not too wet or too frosty
  • Fork over vacant ground; turning the ground over several times reduces soil pests naturally by exposing them to birds
  • Clear away debris to prevent harbouring slugs and snails

Vegetables and herbs

  • Harvest Brussels sprouts, Christmas broccoli, parsnips and leeks
  • Store harvested vegetables in the shed, as long as it’s not damp

Under cover

  • Tidy plants in the greenhouse and conservatory, and water plants sparingly
  • Sow onions
  • Check bulbs in store and remove any going mouldy or soft before the rot spreads to their neighbours

Lawns

  • If it’s very wet or frosty keep off the lawn if possible, or protect it with a temporary path and sprinkle with sand if it’s slippery
  • Remove the last of the dead leaves from the lawn
  • Carry out lawn repairs if it’s not too wet or too frosty

Ponds

  • Make provisions to prevent the pond from freezing over by floating an inflatable ball on the surface. If the water freezes over, place a pan of boiling water on the surface of the ice to melt a hole. Carefully hold the pan in place whilst it does its job.

Trees, shrubs and climbers

  • If the soil is workable, plant or move deciduous woody plants such as trees, shrubs, roses and hedges. Dig them up once the leaves have fallen and re-plant them
  • Renovate old trees, shrubs and climbers, but don’t cut them right back to nothing. Just cut out the oldest branches (the ones that are thickest with the darkest bark). Leave the other branches for now. Just remove a few each year and in 3 or 4 years you’ll have replaced the whole plant.

Flowers

  • Sow seeds of hardy plants, such as lilies, Japanese maples and clematis

Patios and containers

  • Plant seasonal outdoor tubs and hanging baskets for Christmas
  • Prevent plant damage from wind and rain by moving tubs close to a wall so they are more sheltered from wind, and stand them on pot feet to aid drainage

Wildlife

  • Put out more food for birds throughout the winter when it’s harder to them to find their own
  • Check bonfires before you light them for hibernating animals
  • Be careful to look for sleeping animals in your compost heap before turning it
  • Provide a shallow, low level container of water for garden visitors like hedgehogs and foxes
  • Leave healthy herbaceous and hollow-stemmed plants unpruned until early spring. These can provide homes for overwintering insects

December garden project: Christmas trees

There's nothing quite like a real Christmas tree, but have you thought about planting it in your garden after Christmas? Imagine having your own gorgeous tree year after year to decorate.

A potted Christmas tree can be bought three weeks or more in advance, but stand it in a sheltered spot in the garden until you’re ready to bring it in and decorate it. For tips and advice on how to care for a real Christmas tree, read our guide.
