Companion planting for pest control also works – e.g. having garlic grow under your roses – the natural pyrethrums deter aphids and other bugs – and allow the lady bugs to stay.
Companion planting is simply the planting of pest deterrent species in close physical proximity to your featured plants, and it helps reduce reliance on pesticides. Advantages include attracting beneficial insects and predators, repelling harmful ones, and aiding growth.
It is a feature of biodiversity – nature’s way of control and balance. Companion planting is especially useful in home vegetable gardens and ground-level fruits (strawberries etc) where there is a reluctance to use chemicals.
The smell of marigolds deters aphids and rabbits. They also attract hoverflies which eat aphids. Nasturtiums are known to attract caterpillars and having them grow in your veggie patch will help protect lettuce, cabbage and the like as the pest prefer the nasturtium! That’s called trap cropping.
Some herbs are also effective pest control companion plants. Some people swear that basil is great with your tomato plants – but the only way to be sure is to experiment with what could be a myth.

Growing corn, broccoli, or radishes near cucumbers can deter cucumber beetles, while members of the allium family (onions, garlic, chives also repel and help prevent fungal diseases. Their flowers attract the ‘good’ bugs.
Pansies grown with onions helps keep the weeds under control – as they grow faster than weeds, while the onion is a slow grower. The onions may actually then protect the pansies from aphids and fungi.
Regular monitoring of your plants for signs of infestation or weakening of the plant will quickly identify any new garden pests and can make early treatment possible.
Before buying a Garden Pest Control device or formula, make sure you have taken all other natural measures to prevent the infestation, and you take a sample of the pest to the garden center so the correct pesticide solution can be administered.
