Winter pots – really useful tips! – The Middle-Sized Garden


November 29th, 2020 Posted In: Container gardening

Did you know that planting winter pots is a little different from planting summer pots?

And that’s not just because the plants need to be winter-hardy.

So I went to our local garden centre, Maytree, with garden designer and Great British Bake Off finalist Jane Beedle to find out more about choosing and planting winter pots.

Jane has a cookery school, Janes Kitchen Kent, where she runs a range of seasonal workshops, including flower arranging and Christmas decorations.

  1. You need more plants in winter pots

When you buy plants for summer pots, you know they will grow. A few small plants can turn into a wonderfully exuberant display.

But plants don’t grow in winter. So Jane advises you to buy more plants than you would in the summer and pack them in tightly. ‘The way they look now is the way they’ll look at the end of winter,’ she says, adding ‘provided that they survive.’

Try out plants in the garden centre before buying

Jane always tries out her pot combinations before buying them. Find a space on a shelf or in your trolley that is about the size of the container you plan to fill. Then pack the plants tightly into that space to see how they look together. ‘If it’s a round pot, group them together in a circle,’ she says. ‘If it’s a window box, there’s often an upper basket on your garden centre trolley that’s much the same size and shape as a window box.’

2) You don’t need to change all the compost in winter pots

Because plants grow in the summer, you need to give them new compost. And you need to feed them.

‘In winter, they won’t be growing, so you don’t need to feed them,’ says Jane. ‘And I just take the top layer of compost off and replace it with new.’

She took off approximately a third of the compost in her pots and window boxes.

Jane only took out the top third of the compost in her pots and window boxes. She’ll change all the compost for the summer pots, however.

3) But watch out for pests…

‘However, if you spot any pests in the compost, you must get rid of all the compost in the pot,’ she advises. Watch out for vine weevil grubs in particular: ‘They’re little white grubs that look like maggots, curled round. They live on the roots and leaves of plants.’

4) It’s easier to switch plants round in winter pots

Jane  used red cyclamen, silver stone pine (Pineus pinea ‘Silver Crest’ and red-berried Gaultheria (Gaultheria procumbens) for this year’s winter pots and window boxes. ‘The cyclamen will probably flower until late winter or early spring. After that you can take them out of the window boxes easily, because their roots won’t have grown. Then you can replace them with something like polyanthus, primula or primroses.’

This is Jane’s red-berried wintergreen (Gaultheria procumbens), Stone Pine (Pinus pinea ‘Silver Crest’) and white cyclamen. Although they are packed tightly, it’ll be relatively easy to take out the cyclamen when they’ve finished flowering because their roots won’t have grown in winter.

5) You can save money if you re-use plants in winter pots

Because you need to buy more plants, winter pots are usually more expensive than summer pots.

Jane re-planted her window boxes from scratch last winter. (See this post about winter window boxes).

Red, silver and green winter window boxes

Jane planted winter window boxes in red, silver and green last year.

Now, a year later, she has re-used all those plants, either in her summer window boxes or in the garden.

‘I hate wasting plants,’ she says. ‘Last winter, I had a silver, green and red theme with eucalyptus, barbed wire plant, ivy and red cyclamen. I gave the eucalyptus to a friend (me) and planted the cyclamen around the garden. The barbed wire plant and the ivy have flourished so Jane has left them in to do their second winter in her pots and window boxes. ‘I don’t think I’ve wasted anything. Which is important because winter pots in particular are expensive. You can spend around £100 on filling a few window boxes and pots. ‘

Evergreen plants in pots are often particularly long lasting. I’ve kept plants going in these pots for several years without changing them. And here is a post on the best plants for amazingly low maintenance pots.

6) And one ‘rule’ which is the same for summer and winter pots

Don’t have too many colours in one pot or grouping of pots! Of course, all rules are made to be broken, so if your heart lifts at the sight of a pot full of different colours, then why not? It’s your garden.

But I’ve noticed that when I ask experts about colour schemes for pots, they always say ‘limit your colours to three.’ And don’t forget that green is a colour.

Pink, yellow and silver for winter pots

Pink, yellow and silver. Jane tried out this grouping of pernyetta (Gaultheria mucronata), Golden sedge (Carex aurea) and stone pine (Pinus pinea ‘Silver Crest’) on a shelf at the garden centre, but decided against it. ‘The pink Gaultheria berries won’t last as long as the red ones,’ she said, ‘and if you plant them in the garden afterwards, they probably won’t berry again unless they have a male plant.’

And a rule can be a helpful thing when you’re faced with an array of plants at the garden centre.

7) Just add lights…

Jane thinks that it’s particularly cheering to add battery-powered fairy lights to winter pots and window boxes. If you buy them with a timer, you don’t even have to remember to switch them off.

Don’t forget that they need to be suitable for outdoor use. I’ve bought these outdoor fairy lights with a timer. Note that links to Amazon are affiliate so I may get a small fee if you buy, but that won’t affect the price you pay. And I only recommend things I buy or use myself.
