I live in central Floida and I am having a difficult time keeping squirrls from chewing the roots off my bulb plants. I have tried the product called "Squirl Away" but it kills the plants. Does fox urine work in keeping the squirls from chewing without harming the plants? HELP! I am a novice gardner and the squirrls are getting the best of me and my garden, literlly. Any advice or suggestions would be greatly appreciated.
