Annual weeds produce thousands of seeds.
They are carried in the wind, by people and animals and each seed develops into more weeds. To break this cycle, don't ever allow annual weeds to go to seed. Get rid of them when they first begin sprouting. Mix in a little flour then add 6 - 8 cups of water. Add 4 cups of stewed tomatoes, a pinch of fresh basil, a tsp of crushed garlic and one cap of soya sauce.
