“Like all plants, every vegetable you eat is part of a specific plant family. Knowing your plant families can help with your planting and harvesting and with your disease and pest control. Organic gardeners and farmers often practice crop rotation. In crop rotation, plant families are cycled from one bed to another (best results occur when families are grown in a specific bed only once every seven years). This gives pest- and disease-susceptible plant families a better chance and ensures that the soil will not be depleted of the same nutreients year after year (since each plant family takes different needs different nutrients from the soil). Plant rotation seems complicated at first but once the families are learned, it can become a simple way create the best vegetable production possible. Containers can be used to add bed space to a small garden and keep the rotation going!”
