Can an interplanted planting cover more than one bed?

Plan one interplanted planting per bed, so your Crop Map shows every companion exactly where it grows. An interplanted planting is drawn over the single bed you drop it on, even when its length would cover more.

For radishes in three carrot beds, create a succession of three plantings with 0 days between them, or three separate plantings, and drop each on its bed. For the Planting amount, enter the bed length the companion really covers in that bed.
