Part of sustainable food production is planting a diversity of crops. Permaculture promotes stacking functions and synergistic plantings of crops and perennials. Every season I make use of the space in between my rows of grapes to grow vegetable produce on a larger scale. This space is normally kept in grass or a cover crop, but this seems like a waste of land when it could be producing more food for sale or home eating. All that space needs to be mowed and maintained throughout the season. In addition, by planting vegetables I can reduce the competition for water and nutrients with the grapes since vegetable root systems are much shallower and less extensive than grass roots. Since starting this practice, I’ve found an increase in the productivity and vigor of the grapevines.
