To keep squirrels out of potted plants, several effective methods exist including natural repellents, physical barriers, and deterrents based on squirrel behavior:
- Natural Repellents: Sprinkling ground coffee, cayenne pepper, garlic powder, or chili flakes on the soil surface deters squirrels due to unpleasant smells. DIY sprays made from fresh mint, garlic, cayenne pepper, or a mix of black pepper, jalapeno, and onion can also be sprayed on plants to repel squirrels safely. Additionally, bone meal mixed into the soil is disliked by squirrels while benefiting plant health, but caution is needed if pets are around. Animal hair, like dog hair, placed in the soil layer can also discourage squirrels by smell.
- Physical Barriers: Using a layer of stones, pebbles, or gravel on top of the soil can prevent squirrels from digging, as they dislike working through these materials. Chicken wire or plastic netting can be placed over or around pots as a cage to physically block squirrel access. Bamboo skewers or plastic forks stuck into the soil create uncomfortable surfaces for squirrels to dig in.
- Deterrents: Shiny objects such as reflective tape, old CDs, wind chimes, or empty cans produce reflections and noise that squirrels dislike. Water squirting by hand or with motion sensors can teach squirrels to avoid the area. Certain plants like marigolds, nasturtiums, alliums, citronella, lavender, and mustard flowers planted among your pots also repel squirrels by smell.
- Additional Tips: Providing alternative food sources like squirrel feeders may reduce their interest in potted plants. Ultrasonic devices emitting high-frequency sounds that humans can't hear can scare squirrels away but might affect pets. Having a cat can naturally deter squirrels from frequenting the area.
Overall, combining these approaches—especially natural repellents on soil, a physical barrier over pots, and deterrent plants or objects—offers a comprehensive way to keep squirrels out of potted plants without harming them or the plants. If needed, specific recipes for repellent sprays and guidance on barrier construction can be provided.
