5 Great Companion Plants for Tomatoes

Tomatoes are what I think about when I think of my summer garden. I can't help it. They are the number one crop I like to grow in the summer.  To help my tomatoes prosper I use companion planting techniques to combat insects and help my plants grow better.  Since we're still a couple weeks away from tomato planting time in Tennessee I thought going over a few companion plants for tomatoes might help you to plan out your garden this year.

Basil is my number one favorite companion plant in the garden.  It's useful in flavoring sauces, salads, and delicious in pesto but is also a great deterrent for insects in the garden.  Basil attracts beneficial insects when in flower (the flowers are edible too) and requires next to nothing to care for it.

Chives and tomatoes seem like a good fit since since they taste great together on a plate but their companion planting attributes go beyond the dinner table.  Chives help to repel aphids and improve the growth of tomatoes.

Many people quickly dismiss mint as a companion plant due to its invasive nature but it does have some value as a companion plant in the garden.  It attracts beneficial predator insects like parasitic wasps when flowering.  These wasps lay their eggs on the hornworms.  The eggs hatch and burrow through the hornworn killing it and stopping the hornworn from devouring tomato plants like Godzilla destroying Japan.  To control mint keep it contained in pots.

Parsley is another great companion for tomatoes.  It attracts beneficial insects and helps to improve the flavor of tomatoes.

Nasturtiums are a garden work horse!  They are great around many plants and work very well as a ground cover around tomatoes.  Nasturtiums help prevent aphids, squash beetles, and whiteflies.  It grows very easily and doesn't need much care once it is started.  You can also plant nasturtiums around squash, cucumbers, pumpkins, and other cucurbits.  As a bonus nasturtiums have edible flowers.

My planting strategy for companion for these companion plants:

Often companion plants can be beneficial to more than one type of plant.  Some of these are mentioned in a previous post I wrote on companion planting last year but those mentioned in this post are ideal for tomatoes!
