Nutri-Guard is not a fertilizer. Nutri-Guard is a repellent designed to keep wildlife out of your gardens and flowerbeds. Nutri-Guard contains a proprietary blend of natural food-based additives that wildlife finds unpalatable. Nutri-Guard is designed to be used in conjunction with Nutri-Plot. Use Nutri-Plot to increase the health and yield of your garden and use Nutri-Guard to keep the wildlife from eating what you have so lovingly grown.
