Supermarket prices for fresh veggies are out of this world – but there’s a way to get the same things for cheaper: grow your own. So we have one of the best ways to make sure your garden is blooming: companion plants! Garden expert and Agriscaping co-founder Justin Rohner is helping us learn which plants are best buds – including the best companion plants for tomatoes.


1. What is Companion Planting?


First – what is companion planting? “First, you grow your primary crop – the thing you wanted most in the garden,” explains Justin. “Second, you want a good companion – something that synergizes with that plant and helps support its basic growth.” Yup, just like you, plants need a friend nearby to help them grow – literally! “There’s so many different types of companion plants that you can also do for protecting against bugs, for supporting the nutrition in the soil, [and] even creating microclimates,” adds Justin.

Now let’s talk about the best companion plants for tomatoes and other crops. For starters, Justin says you want another plant that’s going to help what you initially planted. “Good examples are like tomatoes and marigolds,” offers the expert. “The tomato might be your primary crop, and that marigold is that secondary crop – that companion plant that will help detract all those nasty bugs crawling up your tomato plant and causing harm to its good.” That’s right! If you know the right companion plant, you don’t need bug spray!


“Another type of great companion planting trio is the three sisters garden: corn, beans, and squash,” shares Justin. This genius combo is time-honored by Native Americans and cultures all over the world. The beans help build up the nutrients in the soil, and the squash plant helps provide shade for the corn to grow tall.


3. Plants That Don’t Work Together


Finally, there are plants that don’t work well together. For example, if you’re trying to grow tomatoes, stay away from corn. And for carrots – avoid coriander and dill! These will actually increase the number of pests your plants suffer from. No Bueno!



Gardens big or small can all benefit from companion planting – and now you know three ways to go about it! Get Justin’s complete companion planting guide here.
