Is Amaranth Deer Resistant? A Deep Dive
While no plant is truly deer-proof, amaranth is generally considered moderately deer-resistant. Deer may browse it, especially when other food sources are scarce, but it is usually not their first choice.
Understanding Deer Resistance in Plants
Deer browsing habits are complex and influenced by factors like deer population density, availability of alternative food sources, local climate, and even individual deer preferences. What’s considered “deer-resistant” in one area might be heavily browsed in another. The term “deer-resistant” is, therefore, more accurately understood as “less appealing” to deer. Plants are usually chosen by deer based on their nutritional value, ease of digestion, and palatability. Amaranth falls somewhere in the middle of this spectrum.
Amaranth: A Resilient and Nutritious Crop
Amaranth is an ancient grain crop originating in Central and South America. It’s known for its exceptional nutritional profile, ease of cultivation, and striking appearance. Beyond its use as a grain, amaranth leaves are also edible and used in various culinary traditions. The plants come in a variety of colors, from vibrant reds and purples to yellows and greens, making them a visually appealing addition to any garden. Furthermore, amaranth is relatively drought-tolerant, pest-resistant (aside from potential deer browsing), and can thrive in poor soil conditions. This resilience makes it a suitable choice for gardeners in various climates and locations.
Factors Influencing Deer Browsing of Amaranth
Several factors can influence whether or not deer will browse on amaranth in your garden:
- Deer Population Density: In areas with high deer populations, deer are more likely to sample a wider variety of plants, including those they might otherwise avoid.
- Alternative Food Availability: During periods of drought or when other preferred food sources are scarce, deer will broaden their diet and may be more likely to browse on amaranth.
- Plant Maturity: Young, tender amaranth seedlings may be more appealing to deer than mature plants with tougher leaves.
- Individual Deer Preferences: Just like humans, deer have individual preferences. What one deer finds unpalatable, another may find acceptable.
- Proximity to Deer Trails: Plants located near frequently used deer trails are more likely to be browsed than those further away.
Strategies to Protect Amaranth from Deer
While amaranth is moderately deer-resistant, taking preventative measures can further reduce the likelihood of browsing:
- Physical Barriers: Fencing is the most effective way to prevent deer from accessing your amaranth plants. Fences should be at least 8 feet tall to deter jumping.
- Deer Repellents: Various deer repellents are available, including sprays, granules, and electronic devices that emit sounds or flashing lights. These repellents often contain ingredients that deer find offensive, such as garlic, hot pepper, or rotten eggs.
- Companion Planting: Planting amaranth alongside other deer-resistant plants, such as lavender, rosemary, or marigolds, can help to deter deer. The strong scents of these plants can mask the scent of amaranth and make it less appealing.
- Motion-Activated Sprinklers: These devices can startle deer and discourage them from entering your garden.
- Rotating Plants: Moving your amaranth plants, if feasible, can disrupt established browsing patterns.

Frequently Asked Questions About Amaranth and Deer
What parts of the amaranth plant are deer most likely to eat?
Deer are most likely to browse on the tender leaves and young stems of amaranth plants, particularly when the plants are still young seedlings. They may also nibble on the developing seed heads, although this is less common.
Does the variety of amaranth affect its deer resistance?
While specific studies are limited, there’s no strong evidence suggesting one amaranth variety is significantly more deer-resistant than another. The plant’s stage of growth and overall availability of food are likely more significant factors. Choosing varieties for their vigor can help them recover if browsing occurs.
Are there any natural deer repellents that are effective for amaranth?
Several natural deer repellents can be effective, including sprays made from garlic, hot pepper, or rotten eggs. You can also try scattering human hair or soap shavings around your amaranth plants. Remember to reapply repellents after rain or heavy dew.
How tall should a fence be to keep deer away from my amaranth?
A fence should be at least 8 feet tall to reliably prevent deer from jumping over it. Woven wire or mesh fencing is generally more effective than wooden fences. Consider also burying the bottom of the fence a few inches to prevent deer from digging underneath.
Is it possible to completely deer-proof my amaranth crop?
While it’s difficult to guarantee that deer won’t ever browse your amaranth, using a combination of strategies, such as fencing, repellents, and companion planting, can significantly reduce the likelihood of damage.
What are some good companion plants to deter deer from amaranth?
Good companion plants for deterring deer include lavender, rosemary, marigolds, salvia, and other aromatic herbs. These plants have strong scents that deer find unpleasant.
If deer browse on my amaranth, will the plants recover?
Amaranth is a remarkably resilient plant. If browsing is not too severe, the plants will often recover and continue to grow. However, heavy browsing can stunt growth and reduce yields. Fertilizing the plants after browsing can help them recover more quickly.
Are young amaranth plants more susceptible to deer damage?
Yes, young amaranth plants are more vulnerable to deer browsing because their leaves and stems are more tender and palatable. Consider protecting young seedlings with netting or row covers.
Can I use motion-activated sprinklers to protect my amaranth from deer?
Yes, motion-activated sprinklers can be an effective deterrent. The sudden burst of water can startle deer and discourage them from entering your garden.
How often should I reapply deer repellent to my amaranth plants?
The frequency of reapplication depends on the product and the weather conditions. Generally, you should reapply repellent every few weeks and after rain or heavy dew.
What are the signs that deer are browsing on my amaranth plants?
Signs of deer browsing include ragged or torn leaves, missing stems, and deer tracks or droppings in the area.
Are there any other animals besides deer that might damage my amaranth?
Other animals that may damage amaranth include rabbits, groundhogs, and birds. Consider taking measures to protect your plants from these pests as well. Using netting or row covers can protect from multiple pests.
