How to grow a wildlife- friendly vegetable garden

Growing vegetables is a great – and tasty – way of attracting wildlife to your garden. Learn about companion planting and how wildlife and growing vegetables can go hand in hand.

Pesticides vs natural pest control

One big step towards growing vegetables with wildlife in mind is to stop using chemical pesticides. These upset the natural balance of the environment and tend to kill everything off: 'pests' (which are wildlife too!) and their predators alike. Afterwards, pests may even recover much quicker without their natural predators to keep their numbers in check. So, try to be a bit more pest-tolerant, and allow their natural predators to do the work for you.

If you have already created a wildlife-friendly garden, all those creatures you have made a home for, such as toads, hedgehogs and birds, are your frontline in pest control.

Given good soil conditions and no water stress, crops will grow strong and healthy, and will be more resistant to pests and diseases. High-nitrogen fertilisers can encourage sappy, leafy growth that’s more vulnerable to attack, so make sure you have a compost heap to provide plenty of animal-friendly, all-purpose soil improver.

Planning your wildlife-friendly vegetable garden:

 

Research pest control

Try and learn as much as possible about the sort of pests which are attracted to your crops and the natural ways of controlling them. These include physical intervention like picking off slugs and aphids by hand, putting up barriers like crushed eggshells to prevent unwelcome intruders, and encouraging natural predators.

Prepare your soil

It’s always good to prepare your soil by adding soil improvers like compost and green manure. Finding out what type of soil you have (for instance, its acidity, whether it’s clay or sandy, and how well it holds moisture) provides clues to what is likely to grow best. A plant grown in the wrong conditions will be stressed and more likely to succumb to pests or disease.

Establishing your vegetable garden:

 

Fertilise and water well

Provide a decent environment for your vegetables to grow in – dig plenty of compost or leaf mould into your plot and make sure it's well watered.

Create a pest barrier

A barrier of coarse bark or sharp gravel around the veg beds will help to deter slugs and snails. If you have raised beds, try running some copper wire around the sides to form a slug- and snail-proof ring.

There isn’t any conclusive scientific evidence about why companion planting works, but it is used with some success. The principle is that certain plants either attract insects away from your crops or actually deter them. Marigolds are widely used to counter eel worms and, at the very least, brighten up the look of your vegetable patch!

Maintaining your vegetable garden:

 

Pick off the pests

Keep an eye out for caterpillars, aphids, slugs and other vegetable chompers and hand pick what the birds and hedgehogs don’t get first.

Wrap up your veg

Use horticultural fleece to cover newly planted vegetables as a non-toxic means of pest control. Don’t forget to provide plenty of other feeding opportunities for the more welcome visitors to your garden who would have eaten the pests you’ve deterred.

Protect your crop

The birds that you have tempted into your garden might not differentiate between what’s meant for them and what’s meant for your table. As long as there is plenty for them to eat, don’t feel bad about protecting your fruit with netting and jangly items like strung-up tin cans and CDs.

 

Top tips

  • Carrot flowers, like all umbellifers, are a big hit with many insects, especially aphid-eating hoverflies, so leave a few to flower.
  • A nearby patch of weeds can be a bonus. It is unlikely to harbour the pests which are detrimental to the veg plot, but may well host many of their predators.
  • Aromatic herbs are really popular with insects, so include things like borage, sage and mint in your veg plot. Sink them into the ground in their pots to stop them spreading.
