Pests and diseases can be organically controlled by planting beneficial companion plants with your fruit and vegetables.
Many plants contain natural chemicals that either deter pests or attract beneficial insects. In some situations they can also enhance the growth rate and flavour of their neighbours. Herbs like thyme, sage, coriander, chives and mint, and flowers such as cosmos, calendula, lavender, Echinacea and marigolds are great at attracting insects. While garlic, onions, parsley, chives, turnips and radishes are useful companion plants, because their pungent aroma repels many flying insects, ants, beetles and aphids.
