Ferns in Pots: Unlocking the Secrets to a Lush, Green Oasis
But here's where it gets controversial... Growing ferns in pots is a popular choice for many gardeners, but is it the best option for all ferns? Some experts argue that certain fern species are better suited for in-ground planting, as they require specific soil conditions and moisture levels that can be challenging to replicate in containers.
And this is the part most people miss... While there are thousands of fern species to choose from, not all of them are ideal for container gardening. In this article, we'll explore the best 5 ferns for pots, according to experts, and provide tips on how to care for them.
The Best 5 Ferns for Pots, According to Experts
Autumn Fern (Dryopteris erythrosora)
- Why it's great: The autumn fern is a hardy, low-maintenance fern that thrives in containers. Its dazzling colors shift gloriously throughout the season, adding visual interest to patios, balconies, and shaded entryways.
- Caring for it: Avoid direct sunlight and place the pot in a shady spot. It's evergreen in milder regions and semi-evergreen in cooler climates.
Dragontail Fern (Asplenium X ebenoides)
- Why it's great: The dragontail fern is a compact, clump-forming fern that reaches six inches tall and up to 12 inches wide. Its unique fronds twist and zig-zag, creating the look of little green 'dragon tails'.
- Caring for it: Place the container on a shaded deck or courtyard and grow the fern in a well-draining potting mix to prevent root rot.
Lady Fern (Athyrium filix-femina)
- Why it's great: The lady fern is an elegant, deciduous fern with bi-pinnate lance-shaped fronds. It's very hardy, tolerating temperatures below -4°F, and can be easy-going, even growing in full shade.
- Caring for it: Die back in winter, but don't prune back fronds until early spring. The fronds can provide shelter for wildlife over winter.
Maidenhair Fern (Adiantum spp)
- Why it's great: The maidenhair fern is very versatile, with over 200 different species. It has delicate, lacy foliage and makes elegant additions in containers.
- Caring for it: Place it in a shaded position on a patio or under taller plants. Keep the soil consistently moist, but not too wet, and water with rainwater whenever possible.
Ostrich Fern (Matteuccia struthiopteris)
- Why it's great: The ostrich fern is a popular deciduous fern for woodland gardens, sometimes known as a shuttlecock fern due to its towering foliage. Its distinctive fronds unfurl each spring before dying back come fall.
- Caring for it: Likes consistently moist soil, and growth is reduced when the soil is too dry. Use a soil moisture meter to keep the container adequately wet, but not waterlogged.
Controversy & Comment Hooks
While these ferns are great for pots, some experts argue that certain species are better suited for in-ground planting. For example, the ostrich fern may struggle in containers due to its large size and specific soil requirements.

FAQs
Can Ferns Survive Winter in Pots?
Ferns can survive winter when growing in containers. How they will fare over winter will depend on your US hardiness zone, and the type of fern. However, remember that any plants in pots are more susceptible to cold than when growing in the ground. To ensure ferns survive the coldest months, you can overwinter plants indoors, move them to a sheltered spot outside, cover plants with frost cloth, or use winter pot covers (like these planter protection bags at Amazon).
Should Ferns Be Cut Back for Winter in Pots?
You can cut back the fronds of deciduous ferns when they turn yellow, if you are bringing them indoors for winter. If the ferns are staying outdoors for winter, leave the old fronds in place to provide shelter for wildlife and to protect the crown from frost. Use clean, sharp pruning tools to cut back brown or damaged fronds in late winter or early spring, just before the new season’s fronds are starting to unfurl.
Underwatering is a common issue for gardeners growing ferns both in the ground or containers, and indoors or outdoors. If your fern is drooping or your fern is turning brown, it can be due to stress caused by underwatering.
A good trick when watering plants in containers is to use your fingers to tell the moisture levels in the soil. If it feels dry a few inches down, the plant needs watering. Or you can use a soil moisture meter for easy, quick results. Regular checking will be crucial to keep ferns at the consistent level of moisture they want to be happy in pots.
