Why Ferns in Pots?
Ferns are often associated with damp woodland floors, but many varieties adapt beautifully to life in containers. Growing ferns in pots offers incredible flexibility. You can position them in those tricky shady spots where nothing else seems to flourish, or bring them closer to your living space to enjoy their delicate beauty up close. Containers also make it simple to cater to a fern’s specific needs regarding soil, moisture, and light, giving you greater control over their environment compared to planting directly in the ground.
For those in colder climates, pots are invaluable for growing less hardy or tender fern species. While many common garden ferns are quite resilient to cold, some varieties prefer a frost-free environment through the winter. Planting these in containers means you can simply move them to a sheltered spot, a greenhouse, or even indoors when the temperatures drop, preserving their beauty for another year.

Choosing Your Fern Friends
The world of ferns is vast, but many readily available types are excellent candidates for container life. When selecting ferns for pots, consider where they will live and your local climate.
- Hardy Ferns: Many hardy ferns thrive outdoors year-round in pots, enduring cold winters. These include popular varieties like Lady Fern ( Athyrium filix-femina) or Autumn Fern (Dryopteris erythrosora). They require minimal winter protection in milder areas but benefit from some shelter in severe cold snaps when potted, as the roots are more exposed than in the ground.
- Half-Hardy and Tender Ferns: These require protection from frost. They are ideal for containers that can be moved indoors during winter. Varieties like Boston Ferns (Nephrolepis exaltata) or many exotic maidenhairs fall into this category, often grown as houseplants or patio plants in warmer months.
- Tree Ferns: Smaller specimens of tree ferns are best grown in containers so they can be brought indoors or into a sheltered, frost-free location for winter. Their growing points are sensitive to prolonged cold.
Generally, most ferns prefer light or dappled shade, mimicking their natural woodland habitat. While some can tolerate a bit more sun, this usually requires ensuring consistently high moisture levels, which can be more challenging in pots. Finding that sweet spot of indirect light is key.
Potting Up Success: Containers and Mixes
Choosing the right pot is crucial for thriving ferns. Large containers are generally preferred as they offer more space for root growth and retain moisture better than smaller pots, which tend to dry out quickly. Ensure any pot you choose has adequate drainage holes at the bottom – ferns like moisture but hate sitting in waterlogged soil, which can lead to root rot. Terracotta pots can look beautiful but dry out faster than plastic or glazed ceramic ones, so factor this into your watering routine.
The soil mix is equally important. Ferns thrive in rich organic matter that holds moisture well but also allows for good drainage. A recommended mix for ferns in containers is:
- Three parts peat-free multipurpose compost
- One part John Innes No. 3 (a loam-based compost providing nutrients and structure)
- One part horticultural grit (to improve drainage)
This blend provides nutrients, structure, and the necessary drainage to keep fern roots happy and healthy in a confined space. Mixing in additional organic matter like leaf mould or well-rotted compost can further enhance moisture retention and nutrient content, mirroring their preferred conditions in nature.
Planting Your Potted Ferns
Planting ferns in pots is straightforward, much like planting other container-grown perennials. Spring or autumn are the best times to plant, allowing the fern to establish roots before facing the stress of extreme summer heat or winter cold.
- Prepare the Pot: Ensure drainage holes are clear. You can place a layer of crocks or gravel at the bottom, although this isn’t strictly necessary if your potting mix is well-draining.
- Add Potting Mix: Fill the pot with your chosen potting mix, leaving enough space so that the top of the fern’s root ball will be just below the rim of the pot.
- Position the Fern: Gently remove the fern from its nursery pot. If the roots are tightly bound, gently loosen them at the bottom. Place the fern in the center of the pot.
- Fill and Firm: Fill around the root ball with more potting mix, ensuring the crown (where the fronds emerge) is level with the soil surface. Gently firm the soil down with your hands – don’t compact it too much.
- Water Thoroughly: Water the pot generously until water drains freely from the bottom. This settles the soil and hydrates the plant.
You can plant single ferns for a minimalist look or combine different varieties or other shade-loving plants like hostas, impatiens, or heucheras in a larger container for a layered, textured display.
Caring for Your Potted Ferns
Ferns in pots require slightly different care than those planted in the ground, mainly due to the limited volume of soil and quicker drying.
Watering
Consistency is key. Ferns prefer consistently moist soil, but not waterlogged. Check the soil moisture regularly by sticking your finger about an inch or two deep. If it feels dry, it’s time to water. Potted ferns, especially those in terracotta or exposed to any sun or wind, will dry out faster than garden ferns. Water thoroughly until you see water come out the drainage holes. Reduce watering slightly in winter, especially for dormant outdoor ferns or indoor ferns in cooler conditions.
Light and Humidity
Most ferns love dappled or indirect light. Avoid direct sunlight, especially during the hottest parts of the day, as it can scorch their delicate fronds. Indoors, place them near a window that doesn’t receive direct sun, like a north or east-facing window.
Humidity is also important, particularly for indoor ferns. If your home is dry, especially in winter with heating, consider misting your ferns regularly, placing the pot on a pebble tray filled with water (ensure the pot isn’t sitting directly in the water), or grouping plants to create a localized humid microclimate.
Feeding
Ferns are not heavy feeders. Mixing in a good organic compost when potting provides initial nutrients. You can supplement this during the growing season (spring and summer) with a weak liquid fertilizer, perhaps once a month, diluted to half or quarter strength. Avoid over-fertilizing, which can harm ferns. Do not feed during the dormant period in autumn and winter.
Repotting
As your fern grows, it may eventually outgrow its pot. Signs include roots growing out of the drainage holes or the plant drying out very quickly. Repot into a slightly larger container (just one size up) using fresh potting mix, ideally in spring.
Overwintering Potted Ferns
How you overwinter your potted fern depends on its hardiness:
- Hardy Ferns: Can remain outdoors. Place the pot in a sheltered location, perhaps against a wall or near the house. Grouping pots can also offer some protection. In very cold climates, you might wrap the pot in burlap or bubble wrap to insulate the roots. Ensure the soil doesn’t completely dry out over winter, but avoid overwatering.
- Half-Hardy/Tender Ferns: These must be moved indoors before the first frost. Find a bright spot that is frost-free, such as a garage, shed with windows, greenhouse, or as a houseplant. Reduce watering significantly, only watering when the top inch or two of soil feels dry. Avoid feeding until spring.
Bringing Greenery Home
Growing ferns in pots is a rewarding way to enjoy these captivating plants. They bring a touch of lush elegance to any space, require relatively simple care once their needs are met, and offer solutions for challenging shady areas. Whether you dream of a miniature woodland corner on your patio or a vibrant green display indoors, ferns in containers are an excellent choice.
