Do Deer Eat Boston Ferns? What You Need to Know

By Sophia Martinez · January 24, 2026

Boston ferns (Nephrolepis exaltata) are generally considered deer-resistant, meaning they are rarely eaten by deer. This makes them a smart choice for gardens in areas with high deer activity.

Why Boston Ferns Are Deer-Resistant

Deer tend to avoid certain plants based on taste, texture, and scent. Boston ferns possess several characteristics that make them unappealing to deer.

Key Factors That Deter Deer

Bitter Taste: The fronds of Boston ferns have a naturally bitter flavor, which discourages browsing.
Texture: The feathery, dense foliage is not palatable compared to softer, juicier plants.
Lack of Scent: Unlike aromatic herbs or flowering plants, Boston ferns emit little to no strong odor that might attract deer.
Low Nutritional Value: These ferns do not provide significant caloric or nutritional benefits for deer.

Comparing Boston Ferns to Other Popular Garden Plants

To better understand where Boston ferns stand in terms of deer resistance, here's a comparison with other common ornamental plants.

Plant Name	Deer Resistance Level	Palatability Score (1–5)	Commonly Browsed?
Boston Fern (Nephrolepis exaltata)	High	1	No
Hosta	Low	5	Yes
Lavender	High	1	No
Daffodil	Very High	1	No
Hydrangea	Moderate	3	Sometimes

Table data source:1, 2

The data shows that Boston ferns rank among the more deer-resistant ornamental plants, with a palatability score of just 1 out of 5. While not completely immune, they are significantly less likely to be damaged than highly preferred species like hostas.

When Deer Might Eat Boston Ferns

Although Boston ferns are typically avoided, extreme conditions can lead to exceptions.

Situations That Increase Risk

Food Scarcity: In winter or drought periods, deer may eat otherwise unpalatable plants.
Overpopulation: High deer density increases pressure on available vegetation.
Young Fiddleheads: Newly emerging fronds may be slightly more tender and appealing.
Potted Plants Near Structures: Container-grown ferns on patios or near homes are more accessible and sometimes sampled.

How to Further Protect Boston Ferns from Deer

Even resistant plants benefit from added protection in high-risk areas.

Effective Prevention Strategies

Use Repellents: Apply organic sprays containing egg solids or garlic every 2–4 weeks.
Install Barriers: Low fences (at least 3 feet high) can deter casual browsing.
Strategic Placement: Grow ferns close to the house or under eaves where deer feel exposed.
Mixed Plantings: Surround with strongly scented herbs like rosemary or lavender for enhanced deterrence.
Motion-Activated Devices: Sprinklers or lights can discourage nocturnal visitors.

Frequently Asked Questions About Boston Ferns and Deer

Do deer eat Boston ferns?

No, deer typically do not eat Boston ferns. These plants are classified as deer-resistant due to their bitter taste, fibrous texture, and low nutritional value, making them an unattractive food source.

Are Boston ferns completely deer-proof?

No plant is 100% deer-proof. While Boston ferns are highly resistant, deer may nibble on them during periods of extreme food scarcity or in areas with very high deer populations.

Can I grow Boston ferns outdoors in a deer-prone area?

Yes, Boston ferns are a safe option for landscapes with deer. Their resistance makes them ideal for shaded gardens, porches, and entryways where deer activity is common.

What should I do if deer start eating my Boston ferns?

If browsing occurs, apply a commercial deer repellent immediately and consider installing temporary fencing. Relocating potted ferns closer to high-traffic areas can also reduce risk.

Are there other ferns that are also deer-resistant?

Yes, most ferns are naturally deer-resistant. Species like autumn fern (Dryopteris erythrosora), ostrich fern (Matteuccia struthiopteris), and cinnamon fern (Osmunda cinnamomea) are also rarely eaten by deer.
