Moving Tomatoes Around the Garden? Think in Plant Families.
Food Systems
Crop rotation changes what grows in a bed from one season to the next. University of Minnesota Extension recommends thinking in plant families. Tomatoes and peppers belong to the same family, so alternating just those two keeps that family in the same bed.
Draw a simple map of the garden and record which crops grew in each space. Use the map next season to choose a different family where space and growing conditions allow.
Rotation is one part of managing the garden. Observe plant health, drainage and watering too, and ask local extension staff for guidance on recurring problems.
