What Plant Do Gophers Hate? The Definitive Guide
Certain plants naturally repel gophers! Caper spurge and members of the Allium family, such as garlic and onions, are among the most effective natural deterrents for keeping these garden pests at bay, offering a safer alternative to traps and poisons.
Understanding the Gopher Problem
Gophers, those industrious burrowers of the rodent world, can be a gardener’s worst nightmare. They tunnel extensively, undermining plant roots and devouring entire gardens from below. Understanding their behavior is crucial to effectively combating their presence. They are primarily vegetarians and love roots, tubers, and bulbs, meaning your prized vegetables and ornamental plants are prime targets. Their tunneling also creates unsightly mounds and can damage irrigation systems.
Chemical and Physical Deterrents: Pros and Cons
Before diving into the plant-based solutions, it’s important to acknowledge other approaches. Chemical repellents, containing ingredients like castor oil, are available, but their effectiveness is often inconsistent and they can pose risks to the environment and non-target animals. Physical barriers, such as wire mesh buried around planting beds, can be effective but are labor-intensive to install. Considering these drawbacks, a natural, plant-based approach is often the most desirable and sustainable solution.
Plants Gophers Loathe: A Detailed Look
What plant do gophers hate? Several plants have demonstrated significant gopher-repelling qualities. They deter gophers through their scent, taste, or even toxicity. Here are some of the most effective options:
- Caper Spurge (Euphorbia lathyris): This plant is considered one of the most potent gopher deterrents. It contains a milky sap that is irritating to gophers, causing them to avoid areas where it’s planted. Be aware that the sap is also irritating to humans and pets, so handle with care and plant strategically.
- Allium Family (Garlic, Onions, Chives, Shallots, Leeks): Members of the Allium family contain sulfur compounds that gophers find offensive. Planting these around susceptible plants creates a natural barrier.
- Castor Bean Plant (Ricinus communis): This plant contains ricin, a highly toxic substance. While very effective at repelling gophers, it’s crucial to remember that all parts of the plant are poisonous to humans and animals. This should only be considered in areas where children and pets do not have access and with extreme caution.
- Fritillaria (Fritillaria spp.): These bulbs contain compounds that are toxic to gophers and other rodents. They are also visually appealing, offering a beautiful addition to your garden.
- Crown Imperial (Fritillaria imperialis): Similar to other Fritillaria, Crown Imperial emits a strong, unpleasant odor that gophers detest.
- Lavender (Lavandula spp.): While not as potent as some other options, the strong fragrance of lavender can help to deter gophers, especially when planted densely.
- Rosemary (Salvia rosmarinus): Like lavender, the aromatic nature of rosemary can contribute to gopher deterrence.
Planting Strategies for Maximum Impact
Effective gopher control using plants involves strategic planting. Here are some tips:
- Border Planting: Surround vulnerable areas with gopher-repelling plants to create a protective barrier.
- Interplanting: Incorporate repellent plants directly among susceptible plants to provide comprehensive protection.
- Clustering: Plant groups of repellent plants together to create a stronger deterrent effect.
- Barrier Baskets: Place repellent plants inside wire mesh baskets around vulnerable plant roots during planting for added protection.
Understanding Toxicity and Safety Considerations
It’s crucial to be aware of the potential toxicity of certain gopher-repelling plants, especially Caper Spurge and Castor Bean. Always wear gloves when handling these plants and avoid contact with skin and eyes. Keep children and pets away from these plants or consider alternative, less toxic options. Proper labeling of these plants is highly recommended.
Alternative Natural Methods to Deter Gophers
While planting specific plants is a major line of defense, there are other natural methods that can complement your strategy:
- Noise Makers: Gophers are sensitive to vibrations. Wind chimes or ultrasonic devices can disrupt their activity.
- Predator Urine: The scent of predators like coyotes or foxes can deter gophers. Commercially available predator urine products can be used.
- Gopher-Proofing Raised Beds: Constructing raised beds with wire mesh bottoms is a highly effective way to protect vegetable gardens.
- Soil Amendments: Adding coarse materials like gravel or crushed rock to the soil can make it less appealing for gophers to burrow through.
Integrating Plant-Based Deterrents with Other Strategies
Planting gopher-repelling plants is most effective when combined with other control methods. This integrated approach maximizes your chances of success. Consider using physical barriers, noise makers, and other natural repellents in conjunction with strategic planting.
Frequently Asked Questions (FAQs)
What exactly makes a plant effective at repelling gophers?
The effectiveness of a plant as a gopher repellent stems from its chemical composition, scent, or even physical properties that gophers find unpleasant or even toxic. Plants like Caper Spurge contain irritating substances in their sap, while members of the Allium family release pungent sulfur compounds.
How long does it take for gopher-repelling plants to start working?
The time it takes for gopher-repelling plants to become effective can vary. Some, like Allium plants, offer immediate repellent qualities due to their strong scent. Others, like Caper Spurge, may require some time to mature and release sufficient repellent compounds. Consistent planting and maintenance are key.
Are there any plants that attract gophers?
Yes, unfortunately. Gophers are attracted to plants with fleshy roots, tubers, and bulbs, such as carrots, potatoes, tulips, and lilies. Protecting these vulnerable plants is especially important.
Can I use gopher-repelling plants in containers?
Absolutely! Planting gopher-repelling plants in containers is a great way to protect specific areas or vulnerable plants. You can strategically place these containers around your garden or even bury them partially in the ground to create a barrier.
How often do I need to replace gopher-repelling plants?
The lifespan of gopher-repelling plants varies. Annuals will need to be replanted each year, while perennials can last for several years. Monitor the health and vigor of your plants and replace them as needed. Regularly check for any signs of gopher activity.
What if gophers are still present even after planting repellent plants?
If gophers persist, it may be necessary to combine plant-based repellents with other control methods, such as physical barriers, noise makers, or trapping. It’s also possible that the gophers are particularly persistent or that the repellent plants are not planted densely enough.
Are there any specific varieties of garlic or onions that are more effective at repelling gophers?
While all members of the Allium family have some repellent qualities, stronger-smelling varieties, such as garlic and onions, tend to be more effective. Experiment with different varieties to see what works best in your area.
Is it possible for gophers to become immune to repellent plants over time?
While gophers may adapt to some control methods, they are unlikely to develop complete immunity to the repellent properties of certain plants, especially those with toxic compounds. However, their preferences may shift over time, so it’s important to diversify your control methods.
How do I protect young trees from gophers?
Protecting young trees from gophers is crucial. Surround the base of the tree with wire mesh extending both above and below ground. You can also plant gopher-repelling plants around the tree to provide additional protection.
