Prepare for Frosty Weather Ahead

As the days get shorter there’s definitely more than a slight chill in the air. As much of the garden goes into hibernation it’s time to think about which plants you need to protect from the oncoming frosts.

Although there are some plants and vegetables that laugh in the face of frost; more on those later, there are many that can’t withstand even the slightest sprinkling. Understanding the types of plants in your garden, and indeed understanding the lay of your garden can really help protect your blooms against winter devastation.

Understanding Your Garden and What’s in It

There will be some parts of your garden that are more sheltered and shady than others. Take some time to learn where these are, particularly where frost pockets hit. Plant hardy plants here and choose the more sheltered areas for your delicate plants. If you’re not sure which plants go where then read on:

Plant Categories

Tender: Tender perennials definitely don’t like frost, they can survive for years if they’re not frost bitten. Move them inside or protect against frost if you want to see them again next year.
Half Hardy: Half hardy plants are usually annuals and are a little, well, hardier, but they can’t take freezing temperatures either.

Frost Hardy: As you might imagine these plants can withstand frost and temperatures of approximately -5C.

Fully Hardy: Nature’s survivors. These tough plants can survive temperatures of around -15C.

Protecting Your Plants

There are many ways in which you can protect your plants from the frost.

Surround the stems of your herbaceous perennials with grit to help stop the plant’s roots becoming sodden and waterlogged. Surround the beds with mulch and bark compost too to help the soil’s drainage. The mulch will break down over the winter too and add some nutrients into the soil.

Move your tender plants inside a greenhouse or indoors and protect others with garden fleece, straw and even bubble wrap!

If you don’t have a cloche or cold frame cover plants such as alpines with a sheet of glass or plastic propped up on logs or large stones. Make sure you keep the sides open to allow air circulation to your plants.

Frost Lovers

Not all plants suffer in the frost; some positively love it! In the vegetable plot cabbages and Brussels sprouts improve with a bit of frost. Kale, parsnips and leeks thrive in this season too and provide a bit of much needed greenery and variety to our seasonal winter plates.

In the flower beds chrysanthemums, passiflora, red hot pokers and hardy fuscias are just some of the plants that seem undeterred by a visit from Jack Frost himself!

Winter proofing your garden is not as difficult as you might think and a little preparation for frost goes a long way to safeguarding your spring blooms.

Designing a Winter Garden

Garden design is all about individual taste. One person’s dream garden can be another gardener’s nightmare! But one thing on which everyone agrees is that a garden should be interesting all the year round. If your outdoor space is as dreary as the weather during the winter months here are a few ideas to brighten it up.

Shapes
Bare branches of ‘ordinary’ trees can look quite extraordinary, especially if dusted with snow. Leaves, stems and seedpods, which are hardly noticed when a plant is in full flower, become the centre of attention when outlined with a sparkle of frost. When planning to introduce new plants don’t forget to find out what different species will look like in winter.

When luxuriant summer foliage has died down, the underlying shapes of the garden can be seen more easily. Stand back and try to pick out the main shapes of both hard and soft landscaping. Taking photographs or making a simple sketch can help.

If beds, borders, lawns, hedges etc. are mostly square or rectangular consider the difference introducing a few curves might make. Likewise, a tall angular shape could give an interesting visual lift to a planting scheme of predominantly soft, rounded shapes.

Colours
Unless you live in a very mild area – or have exceptionally green fingers – you won’t be able to produce floral displays as vibrant and varied as those of summer. A window box or tub near your door planted with winter-flowering pansies is the easiest way to provide a bright welcome to visitors.

Most plants that flower in the coldest months tend to have small, paler flowers but that doesn’t make them any less attractive. Light colours show up well against dark backgrounds and seem to reflect even the weakest winter sun.

Snowdrops are an obvious choice, although choosing from the hundred or so available varieties can be confusing! The common snowdrop (Galanthus nivalis) is one of the earliest to flower in January, while others are more likely to appear in February or March. Winter-flowering heathers, hardy cyclamens (Cyclamen coum) and hellebores can also be relied on to flower early.
In spite of its name, the Christmas Rose (Helleborus niger) rarely blooms at Christmas but it is well worth waiting for its large, white flowers to appear from January to March.

But flowers are not the only sources of colour. Red, orange and yellow berries brighten up dull days – at least until the birds have feasted on them.

Tree bark also comes in a wide range of colours. Most people can recognise a silver birch (Betula pendula) by its white trunk, but it also has many attractive cousins such as the hardy river birch (Betula nigra) which has peeling, cinnamon-coloured bark. Many acers reveal colourful and patterned barks once they’ve shed their beautiful autumn leaves.

If you haven’t enough room for trees, perhaps you could find space for some dogwood. There are many varieties, all with colourful stems ranging from yellow to deep red and almost black.

Scents
What’s better than flowers in midwinter? Scented flowers! Many early-flowering shrubs bloom from December and smell wonderful! If you plant your favourites near your door or alongside your most-used paths you can enjoy them every time you go outside. Some of the most popular are Wintersweet, Mahonia, Viburnum, Winter jasmine, Witch hazel and Winter honeysuckle, all of which have several varieties.

Wildlife
Winter is the time when many people become more aware of the wildlife in their gardens. It’s easier to see birds in the branches of bare trees, and tracks left in snow give clues to unseen night visitors. A harsh winter often makes normally shy creatures venture closer to houses in search of food so this is the best time to encourage them.

A well-stocked bird table or hanging feeders placed within easy view of your windows can attract a surprising number of species. As well as entertaining you with their antics, birds will reward you for your generosity by searching the rest of your garden for overwintering insects and soil pests. Why not help them further by putting up some nest boxes in readiness for spring? It won’t be long!

Preparing Your Garden for Winter

It seems as though we’ve only just begun to enjoy the British summer when the days become shorter and trees take on their autumn colours. There might still be a few more warm days to come, but this is the time of year when gardeners’ thoughts should turn to winter.

Preparing your garden for winter is mostly about tidying up and preventing problems that can occur in the colder months. There’s not always a clear division between the seasons – early frosts can be followed by a spell of milder temperatures – so plan your work by the weather forecasts rather than the calendar.

Clear up Fallen Leaves
If you (or your neighbours) have lots of trees, clearing up fallen leaves can be a big job. But think of all that lovely, free leaf mould! You can add some leaves to your compost heap but, as they rot more slowly than softer material, it’s better to deal with large quantities separately. Mix with a few lawn-clippings and place in sacks or plastic bin-liners pierced with some ventilation holes. Store the sacks in an out-of-the-way corner of the garden. Around this time next year, the leaves will have broken down into a rich, crumbly compost.

When they have lost their leaves, it’s easier to spot and deal with dead or diseased branches on deciduous trees and shrubs. If you are worried about the safety of large, overhanging branches ask the opinion of a tree expert before winter gales arrive.

After clearing most of the leaves, it’s time to tend the lawn. As growth slows down mow it less frequently and raise the cutting height a little. Scarify the lawn by giving it a good rake to remove dead grass and any moss. Then spike all over with a garden fork, lifting the turf slightly as you do so. This will allow oxygen to get into the compacted soil, encourage deeper root growth and improve drainage. If you have a large lawn and don’t relish the prospect of doing this work by hand, you can hire machines to do both jobs. Finish off with an application of lawn fertiliser, making sure you’ve selected an autumn mix that will nourish without promoting rapid growth.

Caring for Tender Plants
If you have any tender plants that you want to overwinter, be sure to pot them up and move them into a greenhouse or conservatory before the first frosts. The biggest danger to hardier plants left outside in containers is that their roots will freeze. Try insulating pots by wrapping them with several layers of bubblewrap or horticultural fleece.

Plants that are not completely hardy but are left in the ground can be protected with a 10-15 cm layer of dry leaves, bracken, straw or bark chippings.

Dropping Temperatures
As temperatures drop, many plants will begin to die down. Remove dead annuals completely and cut down unsightly dead material on perennial plants. But don’t use the shears and secateurs too eagerly. Many plants, such as ornamental grasses and those with unusual seedpods can still look attractive, especially when sparkling with frost. Another reason to leave on the dead flowers of mophead hydrangeas is that they protect the tender buds that will produce next year’s flowers.

Strong winds and heavy rain often do more damage than snow and frost. Make sure climbers are securely tied to their supports and check that tree stakes are still firm. If strong winds are a particular problem in your garden consider making temporary windscreens with netting or hessian stretched between posts, especially around evergreens and newly planted shrubs. Don’t put up solid barriers as these can cause even more wind turbulence.

Garden Repairs
Once the summer foliage has died down, the garden’s hard landscaping becomes more noticeable and is often easier to reach. Check your boundaries, paved areas, raised flowerbeds and screens. A simple repair to a damaged fence panel now could save you having to replace the whole thing after it has failed to stand up to a winter storm. Small cracks in concrete or brickwork will only get worse after hard frosts, and those wobbly paving slabs you’ve been meaning to fix all summer could be much more dangerous when they’re covered with snow.

Pond Life
If you have a pond, remove dead foliage from aquatic plants along with as many fallen leaves as you can. Ice will be your biggest problem. If the whole surface of the pond freezes, the pressure of the expanding ice can damage the walls. Fish can survive the cold, but they can be killed by poisonous gases such as methane and hydrogen sulphide that become trapped under a layer of ice.

One solution is to buy an electric heater designed to float on the surface of the pond. It only needs to be switched on when there is a risk of ice forming and it will keep a large enough hole open to enable gases to escape. Moving water freezes less easily than still, so keeping a fountain running will have the same effect.

If the pond does freeze over completely don’t be tempted to smash the ice if you have fish; the shock waves can kill them. Standing a pan of hot water on the ice will melt a hole and then you can siphon out some water to leave an air gap between the ice and water.

Retire to the Shed
When bad weather prevents work outside, retire to the shed or garage and give a little attention to your tools. Clean and oil metal parts and give wooden handles a wipe with a cloth dipped in linseed oil. Now is a good time to have the lawnmower serviced.

Finally, settle down indoors with seed and plant catalogues and begin to make plans for next year!
