Winter Containers That Look Good Until March

What makes a winter container last until March?

A winter container lasts when every plant in it is hardy and looks good for months, not weeks. Use the same thriller, filler, spiller idea as a summer pot, just built from evergreens and winter flowers.

The thriller is the tall centrepiece, usually a skimmia or a dwarf conifer. Fillers pack the middle: carex, heuchera, cyclamen and violas. Spillers soften the rim, with ivy or Gaultheria trailing over the side.

Plant closely, because winter plants barely grow. What you plant in October is roughly what you’ll see in February. If you’d rather have masses of flowers than evergreen structure, the winter bedding plants guide picks the bedding that keeps going.

Plant winter pots close enough to touch from day one. They won’t fill out much before spring.

Three winter container recipes for a doorstep

Each recipe fills one 40cm pot. Buy the fillers in 9cm pots and the centrepiece as a bigger plant, usually a 2-litre pot.

Tuck dwarf daffodils and crocus in at planting time. They pop up between the violas just as winter ends.

Recipe one: classic red and green. One Skimmia japonica ‘Rubella’ in the centre. Three hardy cyclamen around it, such as Cyclamen coum, which flowers in late winter. Two deep red violas at the front, and one ivy ‘Glacier’ trailing over the rim. The skimmia’s red bud clusters hold all winter and open into scented flowers in spring.

Recipe two: gold and bronze for a shady doorstep. One Carex oshimensis ‘Evergold’ as the centrepiece, with its gold-striped leaves arching out. Two Heuchera ‘Marmalade’ for bronze-orange leaves. Two orange violas. One Gaultheria procumbens for red berries, but only if you use ericaceous compost. This one copes well with a north-facing step. The heuchera growing guide covers which varieties keep their colour in shade.

Recipe three: the bulb encore. Recipe one, plus dwarf daffodils such as ‘Tête-à-Tête’ and crocus such as ‘Ruby Giant’. Plant the bulbs about 10cm deep under the other plants at planting time. They push up between the cyclamen in late winter, just as the violas start to tire. It’s a mini version of bulb lasagne planting.

Pet note: Cyclamen are toxic to cats and dogs. If you have a pet that chews plants, swap them for extra violas or heuchera.

The best plants for winter containers compared

These are the dependable winter pot plants, with what each brings to the mix.

Violas often stop flowering in a cold snap, then pick up again in milder weather. The pansies and violas guide explains how to keep them going with deadheading.

Carex and heuchera shrug off a frosty morning. Their leaves often look even better with a sugar coating of ice.

Which compost should you use for winter pots?

Use a half-and-half mix of John Innes No. 3 and peat-free multipurpose. Add a handful of grit on wet or windy sites.

The loam in John Innes adds weight, so pots don’t blow over, and it keeps its structure all winter. Straight multipurpose tends to slump and get soggy by January.

You don’t need a layer of gravel in the base. Just cover each drainage hole with a crock so compost doesn’t wash out. Skimmia and Gaultheria prefer acid conditions, so use ericaceous compost for them if your tap water is hard.

Always start with fresh compost. Old compost from summer pots may hold vine weevil grubs, which love heuchera roots. The vine weevil guide shows what to look for.

Which pots survive frost?

Look for frost-proof on the label, not just “frost-resistant”. Glazed ceramic, fibre-clay and good stoneware are reliable. Heavy-duty plastic is a sensible budget choice for a windy doorstep.

Cheap terracotta soaks up water, which freezes and can crack or flake the pot. Whatever you choose, raise it on pot feet so water drains away. Take saucers away for winter, as standing water freezes and rots roots.

Pot feet are the cheapest winter insurance going. They lift the pot out of puddles so it can drain.

How often should you water containers in winter?

Water only when the compost is dry, which may be every week or two. Doorstep pots sit in the rain shadow of the house and eaves, so they dry out more than you’d think.

Push a finger a few centimetres into the compost. If it feels dry, water in the morning on a mild day, so the surface drains before night. Don’t water frozen compost; wait for a thaw. Winter pots don’t need feeding until spring.

The finger test works in winter too. If the compost feels dry a few centimetres down, give it a drink.

Looking after skimmia and the rest after winter

Skimmia is the plant most worth keeping. In spring, once the pot is past its best, plant it in a shady border or move it to its own pot of ericaceous compost. The skimmia growing guide covers feeding and pruning.

Heuchera, carex and ivy can go into the garden too. Violas can stay until they get leggy in late spring, then make way for summer planting. Hardy cyclamen are happy planted under shrubs, where they’ll spread over the years.

In a hard freeze, a loose layer of fleece over the plants keeps flowers looking fresh. The garden fleece guide explains how to use it without crushing them.

Common winter container mistakes

• Planting too late. Pots planted in late November sit still until spring. Aim for late September to mid-October.
• Planting too sparsely. Summer spacing relies on plants filling out. Winter plants won’t, so plant them touching.
• Buying tender cyclamen for an exposed step. Big florist cyclamen are damaged by hard frost. Use hardy types outdoors, or keep the big ones in a porch.
• Leaving saucers under pots. Trapped water freezes and rots roots. Swap saucers for pot feet.
• Forgetting to water. Pots under the eaves can go bone dry even in a wet winter.

Frequently asked questions

When should you plant winter containers?

Plant them between late September and mid-October. The compost is still warm enough for roots to settle before growth stops. Pots planted in late November tend to sit still all winter and never quite fill out.

What plants last all winter in pots?

Skimmia, carex, heuchera, hardy cyclamen, violas and ivy are reliable choices. Skimmia ‘Rubella’ holds its red buds all winter. Gaultheria adds red berries but needs ericaceous compost. Large florist cyclamen are tender, so keep them for sheltered porches.

Do you need to water containers in winter?

Yes, whenever the compost feels dry. Doorstep pots sit in the rain shadow of the house, so rain often misses them. Push a finger a few centimetres into the compost every week or two and water on a mild morning if it is dry.

Will terracotta pots crack in frost?

Cheap terracotta can crack or flake in hard frost. It soaks up water, which freezes and expands. Choose pots labelled frost-proof, or go for glazed ceramic, fibre-clay or sturdy plastic, and raise them on pot feet so they drain.

What compost is best for winter containers?

A half-and-half mix of John Innes No. 3 and peat-free multipurpose. The loam adds weight and holds its structure, while the multipurpose keeps it open. Add a handful of grit on wet, exposed sites. Use ericaceous compost for skimmia or Gaultheria if your water is hard.

How many plants fit a 40cm winter container?

Five to seven plants fill a 40cm pot. Winter plants make little new growth, so plant them close enough to touch. Use one tall centrepiece, three or four fillers and one or two trailers at the rim.

The same plants work at a smaller scale too, so try them in our winter hanging baskets next, or browse more how-to guides.
