Companion Planting Information and Chart

Posted by Stephanie Ladwig-Cooper over 12 years ago

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"?

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…
