Putting your garden to bed for winter

Putting your garden to bed for winter

Award-winning garden designer Kate Gould tells us how she protects her garden over the frosty winter period and offers some top tips on jobs to tackle at this time of year

When I think of a winter garden I think of evergreen structure and seed heads dusted with frost backed by a clear blue sky. Our winters are now so unpredictable in the UK and certainly in South East England that we cannot guarantee those crisp, cold, sunny mornings that warrant planting a garden solely for its winter seed heads. My own garden is full of late summer colour and this can continue until mid-November if I am lucky and the weather is kind.

Over the years many plants with winter structure have crept into the planting palette but my garden errs on the damp side in places and plants that should look good during the winter months in a ‘crispy dead’ sort of way just look ‘soggy dead’ instead. So, this year I have hardened my heart and I am going to cut it all down before the cold really sets in, feed it and mulch it with well rotted manure to prepare it for the summer next year. I will miss the golden buff Miscanthus and Hydrangea and I will certainly leave some of the berried plants for the birds.

Normally I leave everything standing to protect the crowns of the plants and don’t cut it down until the middle of January, but a 5cm mulch of organic matter will give the same effect and if I can get it on the ground while the soil is still warm then all the better. This practice is also useful if you have a garden with plants that are generous with their seeds (Verbena, Lythrum, Althaea and Papaver to name a few). A thick mulch can help quash unwanted seedlings next year, it wont get them all but since the Verbena I have seed in their thousands, I am hoping it will for quite a lot of them.

The same goes for tender plants or those with very fleshy stems; Zantadeschia aethiopica, Gunnera and Rheum especially benefit from mulch in cold gardens and a layer of straw and manure keep the worst of the winter wet away from them as well as keeping the surrounding soil from freezing too hard. As with all mulch just keep it away from the stems of the plant to avoid rotting them.

If you garden in a Mediterranean way with gravel and scree then adding more gravel to the garden gives the same effect as organic mulch. It obviously wont feed the plants but most of these plants are quite happy on a lean diet and don’t require the boost.

There are also some tough pruning jobs to tackle in my garden and a 15-year-old Amelanchier ‘Obelisk’ that has looked decidedly unwell for most of this year will probably have to be removed. It was rocked heavily by a gust of wind in the spring and is really beginning to lean over. This will leave a gap but that isn’t a problem; the only problem is deciding what new plant to put there in its place. In fact, that whole border requires a re-think as the Crocosmia ‘Lucifer’ has taken hold and is vying with the Thalictrum for dominance.

Other jobs that you might like to tackle before and during the winter are:

- Tie in climbing plants to make sure they are secure and the wind doesn’t damage them over the winter, this is especially important for climbing roses.
- Rake up autumnal fallen leaves out of the borders and off lawns and compost to provide an organic mulch next year. Leafmould is a great soil improver and information about how best to make this can be found at www.rhs.org.uk.
- Clean your pots. It isn’t the most pleasurable of jobs but will help to keep pests and diseases at bay next year. If you are lucky enough to have somewhere frost-free to store them, do so after cleaning.
- Plan for next year, whether it’s a landscaping project, vegetable garden or simply a new herbaceous planting plan inspired by a seed catalogue: www.chilternseeds.co.uk.
- We aren’t the only ones to use our gardens and if the winter is harsh provide food for the birds in your garden (safe and away from pets and other animals) and keep doing so regularly until the weather warms up. You can find out more at www.rspb.org.uk.
