Cantitoe Corners: Martha's Vegetable Garden
Rotation of the Earth
Each year, the vegetables are planted in different beds to lessen disease problems and interrupt the life cycle of pests that are attracted to a particular plant. Crop rotation also allows the soil to replenish after hosting heavy feeders, and alternating deep-rooted and fibrous-rooted crops from year to year improves soil structure. Marigolds are interspersed amid the vegetables because they are believed to repel insects, and calendula is planted for its edible petals, which add color to salads.
