Black-Eyed Susans (Rudbeckia hirta) are popular garden flowers, known for their vibrant, daisy-like appearance and adaptability. Gardeners often wonder about how local wildlife, especially squirrels, interact with these plants. This article explores squirrel behavior around Black-Eyed Susans and offers insights for protecting your garden.
Do Squirrels Eat Black-Eyed Susans?
Squirrels do not typically consider Black-Eyed Susans a primary food source. While their varied diet includes nuts, seeds, and fruits, the foliage and flowers of Black-Eyed Susans are generally not a preferred part of their menu. Instances of squirrels consuming significant portions of these plants are uncommon.
However, squirrels are opportunistic feeders and may occasionally nibble on parts of the plant. This behavior is more likely during periods when usual food sources are scarce, such as late winter or early spring. They might investigate the plant, but extensive consumption of leaves or petals is rare. Black-Eyed Susan seeds are also not a top choice for squirrels compared to other options.
Why Squirrels Interact with Black-Eyed Susans
The limited appeal of Black-Eyed Susans to squirrels stems from their taste and plant compounds. The foliage has a coarse texture and a bitter taste that deters squirrels. These plants may also contain mild irritants or compounds that make them less appealing. While not toxic to squirrels, these compounds contribute to their disinterest in consuming the plant material.
Squirrels are primarily seed-eaters, preferring acorns, walnuts, and sunflower seeds. Although Black-Eyed Susans produce seeds, these are smaller and less energy-dense than the nuts and larger seeds squirrels typically prefer. Consequently, squirrels usually bypass Black-Eyed Susan seeds for more nutritious options. If preferred food sources become scarce, squirrels may investigate Black-Eyed Susans out of necessity.
Identifying Damage to Your Black-Eyed Susans
To determine if squirrels are responsible for damage to your Black-Eyed Susans, observe specific signs. Squirrel damage often appears as scattered soil around the plant’s base, indicating digging. They might also pull up or partially uproot young plants while burying or searching for cached food.
You may notice nibbled stems or missing flower heads, especially in areas with high squirrel activity. However, extensive leaf damage is less common with squirrels. To differentiate, deer leave ragged tears on foliage, while rabbits make clean, angled cuts on stems. Slugs and snails leave slime trails, and insect damage typically presents as small holes or chewed edges on leaves.
Protecting Your Black-Eyed Susans
If squirrels frequently interact with your Black-Eyed Susans, several methods can protect your plants. Physical barriers are effective, especially for newly planted or young specimens. Place chicken wire or mesh netting around individual plants or entire beds to prevent access.
Natural or commercial repellents can also deter squirrels. Some contain capsaicin for an unpleasant taste, while others use predator urine scents. Always follow product instructions for safe and effective application, as reapplication may be necessary after rain or over time.
Consider providing alternative food sources away from your garden to redirect squirrel attention. A bird feeder with squirrel-friendly seeds or a designated feeding station can draw them away. Maintaining a tidy garden by promptly cleaning up fallen seeds, nuts, and fruits also reduces attractants.
