Do Marigolds Really Keep Squirrels Away From Tomatoes? The Great Garden Debate
No, despite popular belief, planting marigolds likely won’t keep squirrels away from your tomatoes effectively. While they may offer some limited distraction, their scent isn’t strong enough to deter hungry squirrels reliably.
The Allure and the Agony: Tomatoes and Squirrels
The sight of plump, ripening tomatoes in your garden is a joy for any gardener. The heartbreak of finding those same tomatoes half-eaten, courtesy of a squirrel, is a universal gardening tragedy. This is why the quest for a squirrel deterrent is a constant for many, and the myth of marigolds as a solution persists.
The Marigold Myth: Where Did It Originate?
The idea that marigolds repel squirrels likely stems from the fact that marigolds have a strong, pungent odor. Many believe this odor is offensive to various garden pests, including squirrels. This belief is partially rooted in marigolds’ reputation as a companion plant, used to deter insects from other crops. However, the effectiveness against larger animals, particularly squirrels, is far less certain.
Why Marigolds Might Seem to Work (But Don’t Rely On It)
There are a few reasons why some gardeners might think marigolds are keeping squirrels away from their tomatoes:
- Limited Repellent Effect: Marigolds do contain compounds with repellent properties. However, the concentration of these compounds is generally not high enough to significantly deter squirrels that are already motivated by the scent and sight of ripe tomatoes.
- Coincidence: Squirrel activity can fluctuate. Perhaps squirrels weren’t interested in your tomatoes the same year you planted marigolds. This could lead to a false correlation.
- Distraction, Not Deterrent: The strong scent might provide a very temporary distraction, but a determined squirrel will quickly overcome it.
More Effective Squirrel Deterrent Strategies
If you’re serious about protecting your tomato crop, consider these more reliable methods:
- Physical Barriers: This is the most effective method. Enclose your tomato plants with netting, cages, or fencing. Make sure the barrier extends underground to prevent squirrels from digging underneath.
- Repellents: Use commercially available squirrel repellents. Look for products containing ingredients like capsaicin (derived from chili peppers) or predator urine. Remember to reapply frequently, especially after rain.
- Trapping: Live trapping and relocating squirrels can be effective, but check your local regulations first, as relocation may be prohibited.
- Diversionary Tactics: Offer squirrels an alternative food source away from your tomatoes, such as a feeder filled with nuts or seeds. Be aware this may simply attract more squirrels.
- Motion-Activated Sprinklers: These sprinklers detect movement and spray a burst of water, startling squirrels and deterring them from entering the area.
- Guard Dogs: A dog patrolling your yard can act as a powerful squirrel deterrent.
The Companion Planting Paradox
While marigolds may not be the ultimate squirrel deterrent, they can still be valuable companion plants for your tomato plants, mainly due to their insect-repelling properties. They can help control nematodes in the soil and deter tomato hornworms and other insect pests.
Marigold Varieties: Does It Matter?
The effectiveness of marigolds as a squirrel deterrent doesn’t significantly differ between varieties. Both French marigolds (Tagetes patula) and African marigolds (Tagetes erecta) have a strong scent. However, the potency of the scent is generally not strong enough to deter squirrels consistently.
Cost-Benefit Analysis: Marigolds and Squirrels
While the cost of planting marigolds is relatively low, relying on them as your sole squirrel deterrent is likely to lead to disappointment and lost tomatoes. Consider them as a supplemental element in a more comprehensive squirrel control strategy.
| Method | Effectiveness | Cost | Maintenance |
|---|---|---|---|
| ———————– | ————- | ——- | ———– |
| Marigolds | Low | Low | Low |
| Netting/Caging | High | Medium | Low |
| Repellents | Medium | Medium | Medium |
| Motion-Activated Sprinklers | Medium-High | Medium | Low |
Common Mistakes When Trying to Deter Squirrels
- Underestimating Squirrel Intelligence: Squirrels are highly intelligent and adaptable. They will quickly learn to circumvent ineffective deterrents.
- Not Addressing All Entry Points: Make sure you are blocking all possible access points to your tomato plants.
- Giving Up Too Easily: Squirrel control often requires persistence and a combination of methods.
- Relying Solely on Scent-Based Deterrents: Squirrels can become desensitized to smells over time.
The Bottom Line
Do marigolds keep squirrels away from tomatoes? The answer is a resounding no, not reliably. While they might offer a minor level of distraction, don’t count on them to protect your precious tomato crop. Focus on more effective methods like physical barriers and repellents.
Frequently Asked Questions About Marigolds and Squirrels
Do marigolds keep all animals away, or just squirrels?
Marigolds are primarily known for their insect-repelling properties. They may deter some other small animals due to their scent, but their effectiveness varies greatly. They are not a reliable deterrent for larger animals like deer or rabbits.
Are there any specific scents that do effectively repel squirrels?
Squirrels are known to dislike the scent of peppermint, garlic, and chili peppers. Using repellents containing these ingredients can be more effective than relying on marigolds alone.
How often should I reapply squirrel repellent sprays?
The frequency of reapplication depends on the product and weather conditions. Generally, you should reapply after heavy rain or every 1-2 weeks, or as directed on the product label.
Will moving my tomato plants deter squirrels?
Moving your tomato plants might temporarily deter squirrels, but they will likely find them again. This is not a long-term solution.
Can I plant other herbs or flowers alongside marigolds to enhance their repellent effect?
Combining marigolds with other strongly scented plants like mint, garlic, or lavender might create a slightly stronger deterrent effect, but it’s still unlikely to be foolproof against determined squirrels.
What is the most humane way to deal with squirrels in my garden?
The most humane methods are preventative measures like physical barriers and repellents. Avoid using poisons or traps that could injure or kill squirrels.
Are there any plants that attract squirrels to the garden, and should I avoid planting them near my tomatoes?
Plants that produce nuts or seeds, such as sunflowers, oaks, and walnuts, can attract squirrels to your garden. If possible, avoid planting these near your tomato plants.
Is it possible that the effectiveness of marigolds varies depending on the location?
Yes, the effectiveness of marigolds can vary based on several factors, including the local squirrel population, the availability of other food sources, and the specific climate.
How do I protect my newly planted tomato seedlings from squirrels?
Protecting seedlings is crucial. Use netting, cages, or cloches to prevent squirrels from digging them up or eating them.
Do squirrels only eat tomatoes, or are they attracted to other vegetables as well?
Squirrels are opportunistic eaters and will consume a variety of vegetables, fruits, nuts, and seeds. They are particularly fond of tomatoes, berries, corn, and nuts.
If marigolds don’t deter squirrels, why are they still recommended as companion plants?
Marigolds are primarily recommended as companion plants for their insect-repelling properties, which can benefit tomatoes by reducing the risk of insect damage.
Besides motion-activated sprinklers, what other deterrents use technology?
Some deterrents utilize ultrasonic sound waves claimed to repel squirrels. Their effectiveness is debated, but they may offer some benefit in combination with other methods.
