Although watching squirrels and their acrobatic talents can be fun, watching them raid your flower will quickly change your mind. These uninvited intruders, who either live in burrows or in trees, can destroy anything in their path, as they seek to satisfy their seemingly insatiable appetite. Your plants and flowers are likely to fall victim to their teeth. Understanding the eating habits and behaviors of squirrels might make it easier to deter them.
Diet and Eating Habits
You're most likely to see squirrels in your garden during daytime; they're active from early to midmorning until late in the afternoon. (See References 1 and 2) In addition to seeds, vines, nuts, fruit, and vegetables, squirrels also enjoy the rhizomes of perennials, corms, and flower bulbs, such as tulips (tulipa spp.), which are hardy in U.S. Department of Agriculture plant hardiness zones 4 through 8, and crocuses (crocuss spp.), which are hardy in USDA plant hardiness zones 3 through 8. (See References 3, p. 78 and References 4) Aside from plant damage, squirrels can also burrow, create mounts, and dig holes in the soil to bury seeds and nuts for later retrieval. This can affect the aesthetic interest of your garden and make mowing difficult. (See References 1)
Growing Undesired Flowers
Rather than growing flowers and plants that squirrels fancy, consider growing plants and flowers that they dislike. This can spare your garden and keep the small intruders at bay. Some examples of squirrel-resistant plants include snowflake (Leucojum spp.), which is hardy in USDA plant hardiness zones 5 through 9; and daffodil (Narcissus spp.) and ornamental onion (Allium spp.), both of which are hardy in USDA plant hardiness zones 3 through 10. (See References 4 and 5). In addition to being undesired, snowflake and daffodil are also poisonous.
Blocking Off Access
Blocking access to your flowerbeds in the form of a cage will make it impossible for squirrels to get to the goodies....
