and the slugs literally explode, releasing another generation of worms to carry on the work. It is unlikely that the worms will move out into surrounding areas in the numbers required for slug control, so the hedgehog population will not go hungry.

      Snails can be kept in check by song thrushes as long as you have sufficient anvils on which the birds can break the shells. If you have no concrete paths or rockery stones, lay a few bricks or large stones around the garden and listen for the tapping as the birds get to work.

      Roses are often planted in vineyards. Hover-flies, which are attracted to the flowers, lay their eggs on the surrounding vines, where their grubs attack harmful aphids and other pests.

Planning your garden

      An abandoned garden soon becomes clothed with nettles, brambles and other invasive plants. Birds and some other animals may appreciate such a wilderness, but your neighbours certainly will not. Diversity is also lost. Good wildlife gardens are planned, not abandoned.

      A wilderness and a wildlife garden are not the same! A wilderness, often defined as a wild and confused mass of vegetation, certainly does not exhibit the variety at the heart of a wildlife garden. It may have advantages for some animals, including the hedgehog and various birds, and there may be short-term advantages for some insects but, if left untouched, the wilderness will succumb to the processes of natural succession and will turn into woodland in 20 years or so. If you want a garden wilderness, restrict it to a particular area and be prepared to tame it occasionally. And plan the rest of your wildlife garden carefully to make the best use of the available space.

      A planned garden does not have to be very formal. The position of this garden pond was actually carefully planned, but the plantlife gives it a wonderfully wild and natural appearance.

      The wildlife garden cannot be ideal for everything; it has to be a compromise. However, by growing lots of different plants you can create wonderful wildlife homes and still have some room for your favourite flowers and vegetables. And you can do this even in a small garden.

       Plan it on paper

      Decide what features you want to include, which, in practice, usually means what you have room for, and then measure your garden carefully so that you can draw an accurate scale plan. Your aim should be to have the flower beds and other more formal or tidier parts of your garden near to the house and let them grade into the wilder-looking areas further away. This will give the whole garden a natural look and still allow you to control its structure. Remember that the pond should be in an open spot and that bird tables should be positioned where you can watch them in comfort.

      When you have decided where everything is to go, you can start thinking about the plants. The soil will influence what you can grow, so have a look at neighbouring gardens and the surrounding countryside to determine which plants do well in the area. You can also use the Internet to find out which members of your local flora are worth planting in your garden (see here). Although native species are best (see here), you don’t have to ignore exotic species altogether. They lend superb colour to the garden and can provide just as much shelter for wildlife as our native species. Many also provide seasonal nectar and fruit.

       Trees and hedges

      Woodland margins are among the richest of all wild habitats, and an excellent way to reproduce them in your garden is to plant a hedge with a wavy margin, preferably on either the northern or the eastern boundary, or both, as this will help provide protection from cold winds without casting too much shade. It will also enable you to grow primroses, foxgloves and many other sun-loving flowers at the base. Include as many different shrubs in your hedge as you can, as this will increase its attractiveness to both birds and insects (see here). A ‘mini-spinney’, with three or four small trees, is another excellent way to mimic the woodland edge.

      Ideally, the hedge should be on your northern boundary, but remember your neighbours: shelter for you might mean shade for them. Birch is a good tree in such a situation because it does not cast deep shade. It also supports over 200 insect species in Britain, and several small birds enjoy its seeds in the autumn. Alder and hawthorn are nearly as effective in this respect. Rowan, bird cherry, hazel and crab apple are other good trees for this situation, or you could try planting a cultivated apple; even a good cooker can support plenty of wildlife, from tiny insects to collared doves, and you can also enjoy the fruit yourself.

      Among the most beautiful of all our spring flowers, the primrose graces the bottoms of many garden hedgerows. Look out for the furry bee-fly plumbing the flowers for nectar with its long, rigid tongue.

      Just a few small trees on the edge of the garden can provide food and shelter for many creatures normally found in a woodland habitat, especially if the herbage is left uncut until autumn.

      Bird cherry is an excellent tree for the wild garden. It can reach a height of 15m (45ft), but it does not cast a dense shade and it is easily kept in check by regular trimming. Laden with heavily-scented flowers in spring, the bird cherry bears shiny black fruits later in the year.

       Garden paths

      These can be made of brick or concrete, or paving slabs laid as stepping stones across the lawn or through the flower beds. For a more natural look, however, you can use chipped bark laid over a firmly-rolled base and retained by a kerb of rustic poles. You can disguise the edge a little by planting violets and bugle here and there and allowing them to tumble over the poles. Some interesting fungi may well spring up on the poles and on the chippings.

      Bugle makes a colourful edging to a garden path in the spring. The wild form and the various cultivars are equally attractive to bees.

      Try to make the paths curve through the garden so that you get new views at every turn and possibly a feeling that you are in a larger area. However, if you cannot do this, you can create an illusion of distance on a straight path by using large chips near the house and smaller ones further away. If your path is on a slope, put in some wooden steps here and there. Old railway sleepers are ideal, and if you drill a few holes in them you will probably attract various solitary bees (see here). You can also drill holes for them
