Insects and other pests evolved along with plants and will always be present. The sensible gardener accepts that low levels of pest attack are inevitable. The time to take action is when intensive attacks cause real damage, and as soon as any pests are seen. Prevention is better than cure.

Good growing conditions
Strong plants are better able to resist attacks from pests and also diseases. So keep plants weed-free and well-spaced to ensure they have adequate access to light and nutrients in the soil. See Controlling Weeds for more tips on battling weeds.

Good drainage is essential for healthy growth. It's best to correct problems before any new planting. Avoid over-applying fertilisers - this causes weak, sappy growth that is attractive to pests. Start right by rotating vegetable crops and selecting plants more resistant to pests and diseases.

Use nature!
The biggest enemies of pests are other insects and animals that eat them! So encourage birds, beetles, frogs and toads into your garden to keep down pest numbers. See Wildlife Gardening for more tips on encouraging wildlife into your garden.
