Companion planting is putting crops together that help each other. Some fix nitrogen for the next plant over. Some pull pests off their neighbour. Some just give shade to a root crop that does not want full sun. None of it is magic and none of it replaces decent soil, but it is free and it works often enough to be worth doing.

Type a crop to find its mates.

Crops that prefer their own bed

What to do with this

Pick the crop you are about to plant, check its row, and slot a companion into the same bed or the next one over. The planting tool tells you the right month for your postcode. The price tracker tells you whether it is worth growing this season at all.
