Companion planting is the age-old practice of planting different plants in close proximity so that they can help one another in some way. These plants complement each other by giving off scent or chemicals that repel insects, or they may attract beneficial insects that are predators to harmful insects. Some plants return micro-nutrients to the soil that can be used by other plants.
Did you know….
• Nasturtiums planted with pumpkins, squash and cucumbers deter beetles, aphids and other insects that attack the plants. And what’s more, they are edible!
• Carrots and leeks are excellent companions. Leeks repel carrot fly and carrots repel onion fly and leek moth. The confusion of scents chases the insects away.
• Asparagus prevents nematodes from attacking the roots of tomato plants.
• Coriander repels insects and can be made into a natural spray to use against red spider mite.
• Garlic deters aphids and is a particularly good choice to plant with roses.
