A Guide to Companion Gardening


What is companion gardening?

Something every gardener will hear at some point when planting a veggie patch is “but what about companion gardening?” This is not an exact science, but most vegetables seem to grow better if paired with other plants. They can help each other by increasing yield, improving growth and helping with pest control. As different vegetables take different levels of nutrients from the soil, companion gardening can also help maintaining a healthy soil.

Planting flowers and herbs next to your veg helps attract essential pollinators, as well as providing a bit of misdirection so to speak for pests, as it is offering an alternate meal.

What plants are good for companion gardening?

Plant nasturtiums with cucumbers and courgettes – a classic combination which works so well attracting pollinators. They also provide a tasty salad addition!
