How to Keep Your Garden Working as an Extra Room All Winter

If your garden hosted an al fresco dinner party or two this summer, you’ll know how quickly it earns its place as another room. Then the evenings draw in, the cushions come indoors and the whole space goes quiet until spring.

It doesn’t have to. For many households, especially where space is tight, the garden does the work of an extra room for half the year, and a handful of sensible changes can keep it in use through the colder months. Think of it as a room you’ll use for an hour at a time rather than a summer evening that lasts until midnight.

Give the dark evenings something to look at

Light is the first thing to sort. The Met Office’s long-term averages for Kew show December bringing roughly 53 hours of sunshine across the entire month, which is under two hours a day, along with about 11 days with at least a millimetre of rain. Most winter time in the garden happens after dark, so lighting does the heavy lifting.

Warm white bulbs at a few different heights feel far more inviting than a single bright floodlight. Think festoon lights overhead, lanterns on the table and a low glow along the path or planting. Choose fittings made for outdoor use and keep cables well clear of standing water. If you’d rather avoid cables altogether, LED candles give you the flicker without the flame. Putting the main lights on a timer means the garden is already glowing when you get home, which does a surprising amount to make it feel like part of the house.

Add shelter over the seating area

If light encourages people out of the door, cover keeps them there longer. A mild December evening can end early once a shower arrives or the damp cold settles into the seating, and parasols only go so far. They blow over, they sit awkwardly above a dining table and they’re usually the first thing to be packed away.

What makes a seating area feel like a room is something overhead. An electric awning with added heating and lighting provides exactly that, with the warmth and light built into the same structure rather than trailing across the lawn on extension leads. Aquarius Blinds explains that a professionally fitted patio awning can provide shade over outdoor furniture and shelter for a garden seating area, so the fitting that shades a July lunch can go on sheltering the table once the weather turns. It’s worth asking how the fabric and frame cope with wind and rain before you choose.

Keep warm without creating a fire risk

Warmth is where gardens most often go wrong. Patio heaters and fire pits are popular, but fire services advise keeping outdoor heaters at least a metre from awnings, fences, sheds and anything else that could catch, never leaving them unattended and securing them against the wind. If you can’t keep that distance, they say not to use the heater at all. Check the manufacturer’s guidance for anything near fabric, and don’t assume a heater that suits an open lawn is safe under cover.

For gentle warmth without a flame, lean on layers. A basket of wool throws by the door, hot water bottles tucked inside and a flask of something hot go a long way.

Choose fabrics and surfaces that cope with the cold

Soft furnishings take a battering outdoors in winter, so pick materials that dry quickly and bring the delicate ones in between uses. An outdoor rug makes paving feel more like a floor and softens the cold underfoot. It also helps to keep any seating close to the house, where the glow from the windows and the short walk back to the kitchen make a cold evening easier to enjoy.

Surfaces need attention too. Algae and moss are prevalent at this time of year and can make hard surfaces slippery, so brush them regularly before they take hold, particularly around the seating and any steps you’ll be crossing in the dark.

Plant for winter shape and scent

You’ll look at the garden from indoors as often as you’ll sit in it, so the planting still matters. The RHS says structure is an important element in the winter garden when flowers are sparse, and its award-winning winter picks include the white bark of the birch ‘Grayswood Ghost’, the twisted stems of contorted hazel and the scented yellow flowers of Mahonia ‘Lionel Fortescue’, which appear in November and December. Evergreens in good pots add year-round shape to a terrace.

Time & Leisure’s round-up of open gardens in south west London and Surrey highlights the planting styles that can be viewed across the area, and is worth revisiting ahead of planning next year’s borders.

A room worth keeping

There’s an additional upside beyond the extra space. The NHS advises getting as much natural daylight as you can, including going outside in the daytime every day, and a sheltered, well-lit corner of the garden makes that easy to do even in wintertime. Treat the garden as a room you keep rather than one you pack away, and the colder months start to look a lot more usable.
