My brother-in-law, John Williams, has a certified organic farm near Midland. You can visit his web site here or follow him on twitter here. Apart from fresh produce and maple syrup, the farm makes a lot of good photographs. Last weekend, I caught John doing some weeding. Before the seedlings come up, he passes a propane-fueled flame over the ground and sears all the weeds. Although more time-consuming than spraying, it’s just as effective and, more importantly, it means you don’t get chemicals in your food.
