Companion Planting Information and Chart

An updated chart of basic companion plants we’ve grown successfully over the years

We recently received an e-mail from a gentleman in China looking for…

… what plants you may have in your garden that you can transplant next to your rose or your apple tree to see how they nurture each other over time.

As a result I thought I would post our own updated list of companion plants for him and anyone else interested. While I would love to say this plant or that plant are "best" I feel I must remind folks to keep in mind your climate, soil and many, many other factors that determine how well these plants cooperate together. Trial and error is the best choice to begin companion planting but the chart below should lead you in the right direction….

What is Companion Planting? A gardening method which makes use of the synergistic properties found in nature: cooperation between plants to achieve optimum health and viability.

Above is a basic chart of companion plants; I’m sure there is a more expansive list out there.  This is simply a chart of plants we’ve been successful growing together — or not — over the years.  The plants are listed by the plants they like, the ones they don’t and also if they are a perennial (otherwise they are an annual or biannual in this Mediterranean climate).

I’m also working on a Plant Guild Matrix or species matrix chart which details various plants, their unique characteristics as well as their specific use and ecological function.  This type of chart easily organizes the mind when designing a plant guild and forest garden — which is a different way of thinking about species cooperation as compared to companion planting.  Plant guilds are composed of a central species — like an apple tree — surrounded by nurturing plant species and occasional animal disturbance.  In essence companion planting is one aspect to consider when designing a plant guild.

  1. It would be interesting to make more of these for every climate. Wild plants could also be integraded, because they also give al lot of beneficials.

  2. I’m so happy to find this website and companion planting chart online. My East Texas garden is already growing very nicely and this companion planting chart has been a great guideline to me. I appeared to have a very happy garden and very much appreciate all the great advice. Thanks so much!

  3. Thank you for your generosity in sharing the companion plants guide… It is very useful!!

    Kind regards, Sabine

  4. Thank you so very much for your response to my question. It appears there is a fair amount of interest in companion planting. I live in the high desert of the Colorado Basin. We are zone 3 to be safe and zone 4 most years. While it is a much different climate as we are near 6000′ elevation and have a hard clay soil My experience is limited with companion planting. I noted some things you have had success with that I found work together. I am using raised beds extensively this year and have one bed that became the “got to save that plant” bed and has tomatoes, parsley, sage, horseradish, basil, jicma, cucumbers, mints, lettuce, chives and a number of other plants. Only the jicma and cucumbers don’t act very happy. Although, once I trellised them they are doing better. I’m growing Valencia peanuts in the shade of kale and they are doing fine now that I have found the key to their water needs. I plant marigolds and nasturtium extensively for insect control. I tried borage one year in the past and again this year. Corn and beans I have planted together since I was a child many decades ago. I tried beans and potatoes and liked the results. Most of my companion planting has been experimental using things I read or heard.. Thank you so very much for the chart. I have hopes it will be helpful with the gardening class I am teaching at the Grange Hall, if that is OK with you.

  5. Hi! I’m so happy to find this.. I’m 20, live in Tasmania and am after the self sufficient lifestyle.. I’ve done a lot of it by myself but it’s good to this stuff to give me a hand. Keep me motivated…

  6. Wondering how closed to plant the onions and leeks, normally I leave six to eight inches between leeks. So would that the spacing for onions and leeks. I am trying to put some in a pot. When I normally grow leeks I grow them in a raised bed in an area by themselves and the onions in another area. But I am doing these in a pot for my daughter. I am a gardener in southeast Texas to central Texas.

  7. hello, i wanna grow organic heirloom seeds in south east london, when you mean fruit trees and fruit tree drip lines i dont fully understand, please elaborate, thx for your time I really appreciate :) <3
