FabaceaeCan you plant carrots and peas together?
No. Carrots and peas are better grown apart. Growing them together gave a smaller combined harvest in a greenhouse or pot trial. That rests on a single study, so treat it as a lead, not a rule.
Why carrots and peas are better apart
Smaller combined harvest. In a greenhouse or pot trial, growing them together gave a smaller combined harvest.

Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
