Ferns have captivated gardeners for centuries with their lush foliage and ancient charm. But when it comes to planting them outside, many wonder: Are ferns good outdoor plants? The short answer is yes—with the right conditions, ferns can be incredibly rewarding additions to your outdoor garden. In this article, we’ll dive into why ferns thrive outdoors, which varieties to consider, how to care for them, and tips to keep them looking their best.
Why Ferns Make Excellent Outdoor Plants
Ferns aren’t just houseplants—they’re versatile, low-maintenance, and naturally resilient. These leafy perennials have existed since prehistoric times and are well-adapted to outdoor environments.
Key Benefits of Growing Ferns Outdoors
- Shade tolerance – Perfect for areas where sunlight is limited
- Low water needs – Once established, many ferns require minimal watering
- Natural ground cover – Ferns spread and fill space beautifully
- Pest-resistant – Generally avoided by deer, rabbits, and insects
- Air purification – Like indoor ferns, they help filter pollutants in outdoor air
With their fine textures and elegant fronds, ferns can bring life to shaded corners, forested paths, and garden borders.

Not all ferns are created equal when it comes to outdoor performance. Here are some of the best ferns for outdoor gardens:
1. Boston Fern (Nephrolepis exaltata)
- Great for hanging baskets on patios or porches
- Prefers humid, shaded environments
- Grows up to 3 feet tall
2. Ostrich Fern (Matteuccia struthiopteris)
- Hardy in USDA zones 3–7
- Tall, vase-like shape makes it ideal for borders
- Spreads through underground rhizomes
3. Lady Fern (Athyrium filix-femina)

Choosing the Right Outdoor Location
To get the most out of your outdoor ferns, location is everything. Most ferns love:
- Partial to full shade
- Moist, well-drained soil
- Sheltered spots protected from strong winds
🌿 Pro Tip: Avoid placing ferns in full sun, as direct light can scorch their delicate fronds.
How to Plant Ferns Outdoors
Planting ferns is relatively simple with a bit of preparation:
Step-by-Step Planting Guide:
- Choose the right time: Early spring or fall is ideal.
- Prepare the soil: Mix in compost or organic matter to improve drainage.
- Dig the hole: About twice the width of the root ball.
- Plant at soil level: Don’t bury the crown—keep it even with the ground.
- Water thoroughly: Keep the soil moist but not soggy.
Once planted, mulch around the base to help retain moisture and suppress weeds.
Outdoor Fern Care Tips
While ferns are generally low-maintenance, some attention helps them flourish.
Watering
- Keep the soil consistently moist but avoid overwatering.
- Water deeply during dry spells or hot weather.
Fertilizing
- Use a balanced slow-release fertilizer in spring.
- Avoid heavy feeding—ferns don’t need much to thrive.
Pruning
- Trim dead or yellowing fronds to encourage new growth.
- Cut back foliage in late fall (for deciduous ferns) to prep for winter.
Winter Care
- Most hardy ferns can survive cold temperatures.
- In colder climates, apply mulch to protect the roots.
- Container ferns may need to be brought indoors if they’re not frost-tolerant.
Common Problems and How to Fix Them
While relatively hardy, ferns can run into a few issues:
| Problem | Cause | Solution |
|---|---|---|
| Brown fronds | Too much sun or dry soil | Move to a shadier area and increase watering |
| Yellowing leaves | Overwatering or poor drainage | Improve soil drainage and reduce watering frequency |
| Slow growth | Lack of nutrients or crowded roots | Fertilize in spring and divide if needed |
Where to Use Ferns in Your Outdoor Landscape
Ferns are incredibly versatile design elements in landscaping. Consider placing them in:
- Woodland gardens for a natural, layered look
- Shady borders alongside hostas or astilbe
- Rock gardens with moss and ground covers
- Hanging baskets on porches or patios
- Container arrangements for mobile greenery
Mixing different fern types can also create visual contrast and texture variation.
Conclusion: So, Are Ferns Good Outdoor Plants?
Absolutely. Ferns are among the best outdoor plants for creating lush, low-maintenance gardens, especially in shady or damp areas. Their unique textures, adaptability, and natural beauty make them standout performers in almost any landscape.
