      Re-cycling the empties: this lacewing larva, pictured with its jaws plunged into an aphid, camouflages itself by piling the empty skins of its victims on its back.

       Cultural control

      Adjusting the way you grow things, or even what you grow, can make your garden less attractive to pests. Most weeds, for example, can be eliminated by spreading a layer of chipped bark or compost over the garden. You can try growing red cabbage instead of the traditional green varieties: this may not deter the cabbage white caterpillars, but at least you can see them more easily and remove them before they do the damage!

      Companion planting or inter-planting is often used to reduce damage by pests. Planting onions and carrots close together works well because the smell of the carrots deters or confuses the damaging onion-fly, and the smell of the onions discourages the carrot-fly. Roses or other flowers planted at the ends of vegetable rows attract hover-flies, which may lay eggs on aphid-infested crops. Some hover-fly larvae can demolish the aphids at a rate of one every minute!

      Doing nothing and allowing nature’s web to keep the pests in check is probably the best method of all. Surely losing a few plants to beetles and caterpillars is a price well worth paying for a garden which is teeming with wildlife and with no risk of poisoning yourself or your family?

       BIOLOGICAL CONTROL

      Biological control, which uses natural enemies to keep pests in check, can be wonderfully effective. Introducing ladybirds and their larvae to your garden, for example, can wipe out an infestation of aphids in days. A single ladybird larva may eat 500 aphids in its three-week development. Green lacewings (see here for stockists) do a good job on summer populations of aphids, and are useful in greenhouses throughout the year.

      Biological control of slugs, which are surely at the top of most gardeners’ hit-lists, can now be achieved simply by using a minute parasitic worm called Plasmarhabditis hermaphrodita. Available through good garden centres and other suppliers (see here), the worms seek out slugs and bore their way in. They multiply rapidly 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 СКАЧАТЬ
