Answer: All plants deplete the soil as they grow. They utilize the nutrients necessary for their specific needs. They also attract specific pests and harbor certain diseases. Plants in a botanical family also use the same nutrients and attract the same pests and diseases. Generally it is recommended that all plants be rotated and a five year cycle works well. Plants like potatoes, peppers and tomatoes, belonging to the Night Shade Family, should not be planted in the same location every year, but rotated todifferent areas. Broccoli, cauliflower, cabbage and kale are in the same family as well as squash cucumbers and melons. In small home gardens rotation is difficult but being aware of its problems can help you better organize it.
