Urban gardening brings joy and greenery to city life, but it can also attract uninvited guests like squirrels. These clever creatures can quickly turn your thriving planter boxes into a buffet. Protecting your plants requires a mix of strategy and humane deterrents.
One of the most effective methods is creating a physical barrier. Covering the soil in your planter boxes with a layer of chicken wire or hardware cloth can prevent squirrels from digging. The plants can easily grow through the openings, but the squirrels' paws cannot. For added protection, consider installing a small wire cloche over newly planted seeds or young seedlings.
Squirrels have a strong sense of smell, which you can use to your advantage. Sprinkle cayenne pepper, crushed red pepper flakes, or coffee grounds generously on the soil. The spicy scent irritates their noses and discourages investigation. You can also make a homemade repellent spray by mixing water with a few drops of cayenne pepper sauce or garlic oil. Reapply these natural repellents after watering or rain.
Another clever trick is to use objects that move or reflect light. Inserting a few bamboo stakes or wooden skewers throughout the planter box creates an uncomfortable landing spot for squirrels. You can also hang old CDs, pinwheels, or aluminum pie plates nearby. The unpredictable movement and flashes of light will make the area feel unsafe for them.
Sometimes, the best defense is a good offense. Planting certain varieties that squirrels dislike can save your garden. Squirrels tend to avoid strong-smelling herbs like mint, rosemary, and lavender. Ornamental plants like marigolds, daffodils, and alliums are also generally left alone. By interplanting these with your more vulnerable vegetables, you create a natural protective border.
Finally, consider providing a distraction. Setting up a separate squirrel feeder stocked with corn or nuts far away from your planter boxes can keep them occupied and satisfied, making your prized plants less tempting. Consistency is key; by combining these methods, you can coexist with local wildlife while enjoying a beautiful, productive urban garden.
