Groundhogs can wreak havoc in gardens, digging burrows and devouring plants. Thankfully, some plants naturally repel these pesky critters. Their strong scents, tough textures, or even toxicity make them unappealing to groundhogs. By choosing the right plants, you can protect your garden while adding beauty and diversity.
Lavender
Lavender’s delightful fragrance not only deters groundhogs but also attracts beneficial pollinators like bees and butterflies, enriching your garden’s ecosystem. Thriving in full sunlight, lavender prefers well-draining, alkaline, or chalky soil. Adding sand can help prevent water retention, which could lead to root rot. During its first growing season, water regularly; once established, lavender becomes drought-tolerant, requiring minimal care.
Hardiness Zones: 5-9
Rosemary
Rosemary’s strong fragrance and needle-like leaves make it highly unappealing to groundhogs. This sun-loving shrub needs at least six hours of direct sunlight daily, thriving in sandy or loamy, well-drained soil. Water sparingly, as the soil needs to dry out between waterings to prevent root rot. You can use a balanced fertilizer occasionally to support its pest-resistant properties, keeping groundhogs at bay.
Hardiness Zones: 8-10
Thyme
The earthy aroma of thyme makes it an excellent plant for keeping your garden free from groundhogs. To grow thyme successfully, plant it in a well-lit spot that receiving 6-8 hours of sunlight everyday. Use well-drained, slightly dry soil and avoid overwatering. In the spring, feed thyme with a diluted, balanced fertilizer to encourage healthy growth and ensure it thrives as a pest-repelling plant.
Hardiness Zones: 5-9
Chives
Chives are a simple yet effective addition to your garden. Their pungent aroma and robust growth deter these pests while providing a versatile culinary ingredient. Chives thrive in moist, well-draining soil with ample sunlight but can tolerate partial shade. Once established, they require minimal care, making them an easy-to-maintain choice for pest control.
Hardiness Zones: 3-9
Mint
The refreshing scent of mint is less appealing to garden intruders, making it a versatile choice. Mint thrives in part shade but needs some sun for flavor and sturdy growth. It prefers rich, well-draining soil with a slightly acidic to neutral pH. Ensure it stays lightly moist during dry spells but avoid overwatering, as soggy soil can cause root rot. Regular watering in the morning helps maintain healthy, vibrant plants.
Hardiness Zones: 3-11
Daffodils
Bright daffodils are an easy way to protect vulnerable parts of your garden. They thrive in full sun but tolerate some partial shade, allowing them to grow in various garden spots. Plant them in well-drained, rich soil with a pH of 6.0 to 7.0. Water regularly in spring and fall, but reduce watering once the flowers fade. These flowers are low-maintenance, requiring minimal fertilization, just a light feeding when the leaves emerge and again when they bloom.
Hardiness Zones: 4-8
Alliums
The pungent aroma of these ornamental onions act as a bold deterrent while adding unique shapes to your garden. To grow them successfully, choose a sunny spot where they can get a full day of light. The soil should be slightly acidic, and you should ensure proper drainage to avoid overwatering. If your soil lacks nutrients, fertilize in late summer. Come fall, trim the plants back once the leaves have dried to keep your garden looking neat.
Hardiness Zones: 4-10
Marigolds
Groundhogs tend to stay away from marigolds owing to their strong scent. These plants grow well in full sun, enhancing their flower production and keeps them robust. Marigolds don’t require rich soil but prefer slightly acidic to neutral pH. While they are drought-tolerant once established, consistent watering helps them bloom beautifully. Regular deadheading will ensure the flowers stay vibrant and continue to deter pests.
Hardiness Zones: 2-11
Snapdragons
The slightly bitter taste and tough stems of snapdragons contribute to their role as a natural barrier in your garden. These flowers flourish in full sun to partial shade, blooming most vigorously in cooler temperatures. Snapdragons prefer well-draining, nutrient-rich soil with a pH between 6.2 and 7.0. Once established, they need about an inch of water per week, ensuring the soil dries out slightly between waterings to prevent rot.
Hardiness Zones: 7-11
Lamb’s Ear
The soft, fuzzy leaves of lamb’s ear are as unappealing to pests and animals as they are attractive to gardeners. To care for lamb’s ear, plant it in well-drained soil with full or partial sun. Space your lamb’s ear plants about 18 inches apart to allow for its fast spread. Water only once a week, ensuring the soil stays dry to medium-moisture, as the plant dislikes soggy conditions. Mulch around the base to keep humidity down and protect the leaves.
Hardiness Zones: 4-9
Peonies
These lush, fragrant flowers create a protective boundary for your garden. To grow them successfully, plant peonies in a sunny spot with at least six hours of direct sunlight daily. They thrive in well-drained, slightly acidic soil. Water them weekly with 1 to 2 inches of water, and after blooming, apply compost and a light dose of fertilizer. Peonies need a cold period during winter to set their spring buds, so ensure they get enough chill time.
Hardiness Zones: 3-9
Foxglove
These bold blossoms are an ideal plant for keeping your garden intact, owing to their toxic nature. Plant foxgloves in a spot with full sun to partial shade, spacing them about 2 feet apart in slightly acidic, moist, and well-draining soil. Stake the plants to keep them upright. Fertilize only if needed, and remove spent flowers after blooming. Be cautious, as all parts of the foxglove contain toxins harmful to humans and pets. Always wear gloves when handling.
Hardiness Zones: 4-10
Bee Balm
With its vivid flowers and strong fragrance, bee balm acts as a colorful yet functional addition to your garden. To ensure optimal growth, plant bee balm in moist, well-draining soil that’s rich in nutrients and avoid overly dry or soggy conditions. Adding mulch will help retain moisture and keep the roots cool. While bee balm thrives in full sun, it can tolerate partial shade, especially in hotter climates. Good airflow is essential to prevent powdery mildew, a common issue with this plant.
