To see good companions for your crops, first click on a plant in your plan to highlight it, then click on the Show Companions button.

All suitable companion plants will then appear in the plant selector, making it easy to add them to your plan.

If you wish you can narrow down the selection to show only plants that help your chosen plant, or only plants that are helped by it. The arrow next to each recommended companion indicates which way the benefit runs. A double-ended arrow means that the plants are considered mutually beneficial.

Find a combined list of companion plants for more than one plant on your plan, by first selecting all the relevant plants.

Use the Selection tool to click and drag the plants, if they are next to each other.

Alternatively click on one plant, then holding the keyboard SHIFT key, click on the other plant or plants.

Next click on Show Companions.

The resulting list of plants is a combined list of companions for either plant selected.

Click on Close Companions or Reset to return to viewing all plants.

We only list companions where there is good scientific evidence to support the association, and we deliberately don't note 'bad companions' because there is much less evidence and widely diverging opinions on this - a lot of it contradictory. In our opinion, getting things like crop rotation right is far more important to the success of crops, although companion planting is a useful tool to fine-tune your garden planning.

Good companions are also listed in the Grow Guide for each plant which you can view by clicking the 'i' information button next to each plant in the plant selector or in your Plant List.

Alternatively double click on the plant on your plan to open the Edit Plant options.

Click on More information and Journal History to view its companion plants and other useful information.
