So its getting cold outside but you still want to garden. Use low tunnels to extend your season and grow cold hearty crops all winter. Ever had a winter carrot or kale? They are amazing! The cold weather actually concentrates the sugars. Plus, come spring, whatever stopped growing will all of a sudden explode with life giving you an awesome quick crop when nobody has anything.
Low tunnels are like mini green houses over your garden row to keep the soil warmer so you can keep on growing and enjoying fresh greens into winter.
