Are squirrels treating your urban planter boxes like their personal buffet? These clever creatures can quickly undo your hard gardening work. Fortunately, you can protect your plants with several effective, humane strategies.
Start with physical barriers. Place a layer of wire mesh or chicken wire just beneath the soil surface. Squirrels dislike the feeling on their paws and will move on to easier digging grounds. You can also cover the soil surface with a layer of large, rough stones or pine cones. This creates an unappealing texture while still allowing water to reach your plants' roots.
Natural repellents work wonders. Squirrels have a strong sense of smell, which you can use to your advantage. Sprinkle used coffee grounds, cayenne pepper, or crushed red pepper flakes around your plants. The strong scents will discourage digging without harming your plants or the squirrels. You can also create a spicy spray by steeping hot peppers in water, then straining and spraying the liquid around your planters.
Make your planters less inviting. Keep the area around your planters clean and free of fallen seeds or fruits that might attract squirrels. Consider planting mint, garlic, or marigolds around the edges of your containers—squirrels tend to avoid these strong-smelling plants.
For persistent squirrels, motion-activated sprinklers or ultrasonic devices can provide an effective surprise deterrent. These devices startle squirrels without causing harm, teaching them that your garden isn't worth the trouble.
Remember that consistency is key. Reapply natural repellents after rain and regularly check your physical barriers. With patience and these smart strategies, you can enjoy your urban garden without constantly battling curious squirrels.
