What to plant next to Celeriac
The good neighbours listed here are traditional garden pairings: they share a bed well, but research has not proven most of the benefits claimed for them. Plants to keep away are listed only where a risk is documented, such as tomatoes and potatoes, which share late blight. Use the lists below when you place Celeriac in the garden.
Why it helps
Mixing crops in the same bed spreads the risk: pests find their target harder, the soil is used at different depths and flowers bring in the insects that pollinate and hunt aphids.

Plan it in the garden
The planner warns you when two crops with a documented shared risk, such as tomatoes and potatoes, end up next to each other, so you can fix the layout before planting.
