How to look after your garden in winter

07 December 2021

Winter may be here but there are a surprising number of tasks to keep you busy out in the garden. Now’s the time to wrap your plants up warm, organise your greenhouse, clear out dead material and plan your planting for next year. There’s even a few things you can start growing if you’re super keen.

So pop on an extra layer and get cracking with our top tips on how to garden in winter. And once you've got your garden straight, you should think about how to prepare your shed for winter - check out our guide!

Prune & Protect

Doing too much pruning in winter is not advised as you can cut away new life but you can prune fruit trees and bushes, wisteria and rose bushes. Cut back dead stems on perennials and remove any faded flowers and old leaves, too.

If the snow comes be sure knock any excess off your plants. The weight and a lack of sunlight can cause real damage.

And be sure to protect your favourite plants from the frost. Here’s how:

Keep out the cold

ITV gardening presenter, David Domoney, writes a weekly column for the Sunday Mirror and blogs at David Domoney.com. He offers lots of advice on protecting plants from cold weather and says keeping them warm and dry is the key to stop plants from dying when temperatures plummet.

David recommends lifting pots using pot feet or old corks to prevent waterlogging, and moving them to a warmer location. Wrap the compost and roots to keep them toasty (but don’t cover the compost surface or your plant will rot):

“A couple of layers of bubble wrap is a great insulator. Or make ‘pot duvets’ from black plastic bags filled with straw or shredded paper. They look a bit odd but they will keep the soil warm.”

In outdoor beds use a layer of mulch, straw leaves or bark around stems to help protect roots from the cold. You can also cover plants that can’t be moved with fleece or cloches to protect them from the cold.

Look after your lawn

Take care of your lawn too. Now is a good time to tidy and repair edges. Keep grass at mid-length throughout the winter. Too short and it’ll have a hard time surviving. Too long and frost will make it brittle. Just make sure you don't take more than about a third of the growth when you mow.

If the weather’s cold, lawn growth will be very slow, so you may be able to leave it alone until the start of spring. Milder weather will mean you’ll have to get the mower out at some point during the winter, though!

Plant

Believe it or not there are a few things you can plant even at this time of year. Onions, cabbage and lettuce can all be sown in trays. Water and keep warm until spring when you can transplant them into your outdoor beds.

Gardening broadcaster and author Paul Peacock says it’s easy to sow garlic, too. Paul continues to enjoy gardening despite having heart failure and diabetes. Writing for the British Heart Foundation, he recommends choosing garlic varieties that are bred for the UK climate, such as Chesnok Wight or Solent Wight. Plant in raised beds or large pots, but as Paul reminds us, make sure you prepare the soil first: “simply take a hoe and chop away at the soil until it looks like crumbly cake mix”.

In the flower garden

Keep your flowerbeds cheerful with plants such as snowdrops and crocus, and plant bare root roses in a sunny spot now for a riot of summer colour.

Dan Cooper blogs as The Frustrated Gardener and says adding colour he can enjoy from indoors also keeps him going through the winter months, too. He recommends planning and planting a few cheerful containers in spots near to the house to spur you on:

On a bright day, leaves fringed with hoar frost, even simple evergreens such as bay, laurel, viburnum and holly are transformed into objects of great beauty.”

Investigate violas, miniature cyclamen and English ivy to create your own potted winter wonderland.

Plan & Prepare

Too cold outside? Sit down indoors with a cup of something hot and make a plan for the coming year. Work out what you want to plant, create a monthly ‘to-do’ list and order your plants and seeds before the Spring rush.

Think about having a dedicated bed for perennials such as rhubarb or asparagus. Dream of summer by thinking about your hanging baskets. Or, order lobelia and geraniums ready for that colour riot.

Take a look in your garden storage for equipment and tools that can be cleaned and serviced. Wipe tools clean, sharpen and give a good spray of WD40 to prevent corrosion. Service your lawnmower. Check and organise boxes of bulbs and take pots and trays inside for a good clean, too.

Now’s also a good time to inspect and repair pergolas, arches, sheds and other garden storage. In dry spells why not add a lick of paint or wood stain too?

Remember Spring is just around the corner. Prepare well now and you’ll be ready for the flurry of gardening activity the new season will to bring. Been out winter gardening? Remember to share your stories, photos and advice on our Facebook page.
