Chemical-Free Gardening
Commercial pesticides and herbicides can cause harm to human neurological, reproductive and integumentary systems. Instead of buying commercial chemicals, consider creating your own blend using one garlic bulb, one medium onion and one tablespoon cayenne pepper mixed into one quart of water. Use this blend as a spray to send away insects and slugs from your garden.
