Companion Planting in the Vegetable Garden

June 6, 2009 by Jocelyn

Last year my garden neighbor had a beautiful garden with flowers, herbs and veggies all mixed together.  It got me thinking, and this year I’m doing some research on companion planting.

As it turns out, certain vegetables will do better or worse depending on what plants are growing around it.  It makes sense when you think about it.  Certain plants take more of different nutrients, or even attract or repel pests.

For instance, basil is a great companion for tomatoes and peppers, as they help improve growth and flavor.  Basil is also known to repel flies and mosquitoes (not particularly beneficial for the plants, but nice for us!)  Another combination that I’m going to try is planting dill and radishes near my cucumbers. Radishes are supposed to repel cucumber beetles, and dill supposedly helps attract “beneficial predators.”  I’m hoping this will work because last year my cukes didn’t fare too well against the pests.

Here are the charts I used from Tinker’s Gardens:

After a bit of puzzling, here is the chart I devised for my garden.  (click to see the larger version)

This is my rough draft, and I may end up changing things a bit as I go.  I just put my tomatoes and peppers in the ground on Wednesday, and have also planted some onion sets, lettuce, basil, and bean seeds.  Hopefully our cold weather won’t persist for too long so my plants will finally have good growing conditions!

    …..I’ve been doing companion planting for 5 years…and I don’t have a fence around my seven 4 x 8 raised beds. Now, the deer, they stink…and usually eat the leaves but not the flowers or beans from my bean plants. And I gave up on beets….

    The best book I ever read on companion planting is called Carrots Love Tomatoes….

    And my sketches every year look just like yours! How funny!

    This has been so helpful.
    Thank you for the fantastic chart.
    Just one question though.
    Did you ever think that you could maximize space
    by utilizing circular and wave based planting shapes?
    In other words doubling up the companions…

  3. […] my Companion Planting post if you’d like more details about plant […]

    I have 3 different gardens in my backyard that I have planted for the past 3 years. I am not allowed a fence so I use netting to keep the deer and rabbits away with. This has worked great. I am making my main garden bigger this year as I want more carrots and beets. This has been so helpful for me. I was never sure what to plant with what. I also have lots of raspberries and some strawberries. I found if I paint little rocks with red paint the birds, thinking they are strawberries, try to eat them and when they can’t they don’t seem to bother them anymore through the season. I also have found that deer do eat daffodil leaves when they first are coming up. Frustrating!
