Companion planting has been around for a long time and is a really good way of using Mother Nature to deter pests and improve pollination.

We’ve put together a Companion Planting Guide which you can find on the Thompson & Morgan website and use to help you plan your vegetable patch.

The guide, written by our horticultural experts, is full of great advice when it comes to growing your crops. For example, many of us grow vegetables in rows, known as ‘monoculture‘. However, pests generally have a favourite crop and this method helps them locate and infest it. Mixing plants up confuses the pests and you’re more likely to have a more successful harvest.

Intercropping is another way to make the most of the available space and is particularly useful when growing Brussels sprouts or parsnips which take a long time to grow. Sow the seeds and while you’re waiting for the them to germinate and grow, sow fast-growing vegetables like salad leaves and radishes and not only will you save a lot of space, you’ll be keeping weeds at bay – less weeding can only be a good thing!

Grow marigolds with tomatoes

Herbs are a great weapon against insects – their pungent scent deters them. Try growing basil, mint and chives near your tomato plants, as well as marigolds, to deter whitefly and aphids. Be cautious when growing mint though, it’s invasive and grows quickly, so it’s best in a container where you can, well, contain it!

Growing onions next to carrots benefits both crops – carrot fly is repelled by the smell of onions, and onion white fly is put off by the scent of the carrots.
