Hardware cloth lines the bottom of this raised bed, and is folded and secured up the outside edges. Unlike chicken wire, hardware cloth has much tighter openings that smaller rodents can't squeeze through! You can find it at home improvement stores in 10 and 25 ft' coils. Chicken wire, however, is the smarter choice for covering your plantings, as it will allow your bulbs to sprout and emerge through the holes.
Squirrels are particularly attracted to newly planted bulbs — when the diggin' is easy! Covering the planting area for the first month or two after planting may be enough to let the soil settle and trick the squirrels. You can cover it with anything squirrels can't dig through but rain can permeate, like chicken wire, hardware cloth or window screens. Planting bulbs later in the fall, after the squirrels have done most of their food cacheing, may prevent some loss of bulbs, too.
Other Squirrel and Rodent Garden Proofing Tips
Instead of planting a solid bed of tulips and crocus, you can try interplanting with some of the bulbs mentioned above that are usually avoided by squirrels. That may offer some measure of protection.
Ideally, you want squirrels to make their meals away from the garden. This may require some trickiness on your part!
- Keep bird feeders away from the garden, or make an effort to clean fallen seed up off teh ground regularly. You can always use the old "if you can't beat them, join them" attitude and set up a special squirrel feeding station. By offering the squirrels a ready supply of easy-to-access food, you might keep them from digging.
- Keep the area mowed and free from rock and wood piles, which offer the perfect habitat. Tidy up after planting, too. Don't leave bulb debris (like the papery "tunics" that fall off tulip bulbs) around the planting area, because it acts like a breadcrumb trail to the bulbs.
- Trees, clotheslines, and other structures near the garden can offer squirrels a sense of comfort and protection when maneuvering through the area. If possible, limit these 'jungle gym'-type networks close to your planting beds.
- The regualr presence of a cat or dog is a powerful way to deter squirrels!
Hopefully, these techniques will help you foil foraging squirrels this fall, so you can enjoy colorful blooms next spring.
