Planting herbs with your tomatoes may lift yields and deter pests
As an obsessive plant collector with little impulse control, I will take any excuse to cram a few more species into my tiny plot. So the concept of companion planting, an old belief that adding certain plants around existing crops can boost pest resistance, yields and even flavour, is one that has always appealed to me. But as a sceptical scientist, I’m curious about how well these claims actually stack up. Let’s dive in.
The tricky thing with examining the science around companion planting is quite how…
Companion planting has been a popular gardening practice for centuries, with the idea that planting certain combinations of plants together can result in mutual benefits. One common example is planting herbs like basil alongside tomato plants. The theory behind this is that basil can help deter pests that commonly affect tomatoes, such as aphids and whiteflies.
Studies have shown that certain herbs, including basil, can indeed have insect-repelling properties. The strong aroma of basil plants can confuse and deter pests, reducing the likelihood of infestations on nearby tomato plants. This natural pest control method can help reduce the need for chemical pesticides, promoting a more sustainable and environmentally friendly approach to gardening.
In addition to pest control benefits, companion planting can also have positive effects on the overall health and yield of tomato plants. Some herbs, like basil, are known to improve the flavour of tomatoes when grown in close proximity. The symbiotic relationship between these plants can enhance the nutrient uptake and growth of both species, resulting in healthier and more productive tomato plants.
While the scientific evidence supporting the benefits of companion planting may vary, many gardeners swear by this traditional practice. Whether you are looking to increase yields, deter pests, or simply experiment with different plant combinations, incorporating herbs like basil with your tomato plants can be a fun and rewarding experience.
So next time you plan your garden layout, consider the potential advantages of companion planting. By strategically pairing herbs with your tomatoes, you may not only enhance the health and productivity of your plants but also create a vibrant and diverse garden ecosystem.
