Fall Fern Transplanting Guide: Tips for Healthy Growth

Autumn’s cool air and moist soil create the perfect conditions for transplanting ferns, your garden’s lush, shade-loving companions. You’ll find that moving them during this season minimises stress on the plants, encouraging healthy root development before winter sets in. With the right approach, you can give your ferns a fresh start, ensuring they thrive in their new location. Ready to get your hands dirty? Let’s dig into the essentials of successful fern transplantation this fall.

Why transplant ferns in the fall

Ideal Weather Conditions

During autumn, the cooler temperatures and reduced sunlight create a less stressful environment for ferns. Unlike the harsh conditions of summer or the unpredictability of spring weather, fall provides a consistent climate that is easier on transplanted ferns. This allows your ferns to acclimatise to their new location without the extra strain of extreme heat or intense light.

Soil Moisture

In most regions, fall comes with increased rainfall which keeps the soil moist. This is essential for newly transplanted ferns as it ensures that your plants have enough water to support root growth. Damp soil also makes digging easier, reducing the risk of damaging the roots during the process.

Natural Growth Cycle

Transplanting ferns in fall aligns with their natural growth cycle. Ferns typically enter a dormant phase in winter, so moving them in autumn gives them time to establish themselves beforehand. This means they can resume active growth in spring from a stronger foundation.

Less Pest and Disease Pressure

With cooler temperatures, pest and disease incidents generally decrease. This lower risk means your ferns have a better chance of thriving post-transplant without the immediate threat of being attacked by aphids, mites, or falling prey to fungal diseases.

Remember, the key to successful fern transplantation lies in the timing. Autumn presents a unique window where natural conditions favour the establishment and future growth of your ferns.

When you’re looking to add lush foliage to your garden through transplantation, selecting the appropriate ferns is crucial. Aim for species that are known for their hardiness and ability to adapt to new environments.

Native ferns often prove to be the best candidates for transplant. They’re already acclimated to your local climate conditions, which drastically improves transplant success rates. Examples of such resilient ferns include:

  • Ostrich fern (Matteuccia struthiopteris)
  • Lady fern (Athyrium filix-femina)
  • Christmas fern (Polystichum acrostichoides)

These ferns not only adapt well but also contribute to a biodiverse ecosystem, supporting local wildlife. When planning your transplant, consider the mature size of the ferns as well. You want to ensure that the space you have can accommodate their growth.

Moreover, assess the soil quality of the transplant site. Ferns typically thrive in rich, moist, well-drained soil with a good amount of organic matter. Doing a soil test before your transplantation project can help you determine if any amendments are needed to create an ideal environment for your ferns.

Lastly, evaluate the light requirements for each fern species you wish to transplant. While most ferns enjoy the shade, some can tolerate partial sunlight, offering you flexibility in garden design.

By doing your homework on the fern species best suited to your garden’s conditions, you can ensure a smooth transition during the optimal transplanting season of fall, setting the stage for these magnificent plants to thrive.

Preparing the new location for transplanting

Before you introduce your selected ferns to a new environment, preparation is key. The efforts you put into prepping the site will determine the health and growth of ferns post-transplantation. You’ll want to start by:

  • Testing the soil pH to match the needs of your ferns, aiming for a range typically between 4.0 and 7.0.
  • Enriching the soil with organic matter such as compost to improve its structure and fertility while also ensuring proper drainage.
  • Removing weeds and debris so your ferns won’t compete for nutrients and water.
  • Digging appropriately sized holes – roughly twice the width of the root ball and just as deep.

Consider the mature size of your ferns when spacing the holes. Most ferns require a gap of about 18 to 24 inches to accommodate their spread. Shielding the transplant site from strong winds and scorching sun by choosing a location with partial to full shade is also prudent. Additionally, verify that the site is at a safe distance from tree roots which can encroach on the fern’s space and nutrients.

Assessing the natural landscape can also inform the aesthetics of your fern placement. For example, a staggered or clustered arrangement can create a visually appealing, naturalistic look.

Water the area thoroughly a day before transplanting. This ensures the soil is moist, encouraging smooth root penetration and reducing transplant stress. It’s also beneficial to water the ferns in their original location to ease the extraction process.

By dedicate time to these preliminary steps, you nurture an environment where your transplanted ferns can thrive.

How to properly dig up ferns

When you’re ready to transplant your ferns, the way you extract them from their current location is crucial. Proper lifting and digging techniques are essential to ensure the survival and subsequent thriving of the plants in their new environment.

Choose the Right Tool

Select a spade or garden fork that’s sharp and properly sized for the fern you’re moving. A smaller hand tool may be perfect for younger ferns, while a larger spade might be necessary for mature plants.

Dig a Generous Perimeter

Begin by digging a wide berth around the fern, aiming for a generous root ball. The goal is to minimize root damage—healthy roots lead to a successful transplant.

  • Start at least 6 inches away from the base for small ferns
  • Increase the distance as the fern size increases
  • Try to keep the root ball intact

Lift Carefully

Once you’ve loosened the soil around the plant:

  • Slide your tool beneath the root ball
  • Gently lift to avoid straining the fern’s stems and fronds
  • If the plant resists, work your way around again to loosen more soil

Keep the Roots Moist

After lifting the fern, wrap the root ball in moist burlap to keep it from drying out. This is especially crucial if not replanting immediately. Avoid exposing roots to direct sunlight and wind. Remember, the less stress on the plant, the better its chances of flourishing after relocation.

Transport with Care

Ensure that during transport, the fern is securely placed to prevent tipping and root disturbance. A flat surface is ideal, offering support to the moist root ball throughout the journey.

By adhering to these steps, you’re not just moving a fern; you’re giving it the best possible start in its new home. Keep these tips in mind and watch as your transplanted ferns take root with vigour.

After carefully uprooting your fern with the appropriate tools and precautions, you’re now ready to transition to the crucial stage of transplanting it to its new home. This process is integral to the survival and prosperity of your fern, so here’s how to do it right.

Prepare the New Site

Before you even lift your fern from its current position, ensure the new site is ready. The soil should be:

  • Loosened to allow easier root establishment
  • Rich in organic matter for nutrients
  • Well-draining to prevent waterlogging

An ideal spot mimics the fern’s natural habitat, typically shaded or partially shaded to protect the fern from direct sunlight.

Planting Your Fern

When planting your fern:

  1. Dig a hole that’s twice as wide as the root ball but no deeper than the plant was previously growing.
  2. Centre the fern in the hole and spread the roots gently.
  3. Backfill the hole with soil halfway and water thoroughly to settle the roots and eliminate air pockets.
  4. Once the water has drained, fill the rest of the hole with soil.

Watering and Mulching

After planting, water the fern generously. Maintain consistent moisture in the following weeks, as ferns thrive best in damp conditions.

It’s also beneficial to add a layer of mulch around the plant to:

  • Retain soil moisture
  • Regulate soil temperature
  • Reduce weed competition

Make sure the mulch isn’t touching the plant’s base to prevent rot.


Monitor your transplanted fern closely. Adjust watering as necessary, keeping in mind weather and the moisture level of the soil. Shelter your fern from harsh conditions and check periodically for any signs of distress, which might suggest further action is required to ensure your fern settles in well.

Once you’ve successfully transplanted your ferns, your focus must shift to proper aftercare to guarantee their health and growth throughout the fall season. Aftercare is crucial during this time as the cooler temperatures and shorter days can impact the plant’s ability to recover.

Maintain Adequate Moisture Levels

First and foremost, ensure that your ferns receive consistent moisture. The post-transplant phase demands regular watering to help the roots establish themselves in their new environment. While the soil should remain moist, take care to avoid waterlogging, which can lead to root rot.

  • Water your ferns early in the morning.
  • Check the moisture level by touching the soil; it should feel damp, not soggy.

Protect the Ferns from Extreme Conditions

Fall can bring unpredictable weather, with sharp drops in temperature potentially damaging to your newly transplanted ferns. Guard against early frosts by:

  • Covering your ferns with frost cloths if a sudden freeze is forecasted.
  • Removing any coverings once the temperature rises to prevent overheating.

Fertilise with Caution

Your transplanted ferns will appreciate a boost as they settle in. However, it’s vital to use the right type of fertiliser and apply it correctly. Opt for a slow-release, balanced fertiliser that will provide sustained nutrition over time. The right fertilisation encourages strong root development, which is essential for overwintering.

  • Apply fertiliser according to the package directions; do not over-fertilise.
  • Cease fertilising by mid-autumn to prevent new growth that won’t withstand winter conditions.

Monitor for Pests and Disease

Finally, you’ll need to keep an eye out for any signs of pests or disease that can take advantage of your ferns’ vulnerable state. Early detection can prevent widespread damage.

  • Inspect your ferns regularly for signs of distress.
  • Treat any infestations or diseases promptly, using appropriate methods for the specific problem.

Your attentiveness in the fall will lay the groundwork for lush, vibrant ferns come spring. Proper care during these critical months goes beyond simple maintenance – it ensures the longevity and beauty of your garden’s foliage.


Transplanting your ferns in the fall sets the stage for a lush, vibrant garden. By providing them with the right care and attention, you’ll ensure they thrive and enhance your landscape. Remember to keep the soil moist, shield your ferns from harsh weather, use fertilizers wisely, and stay alert for any signs of trouble. With these steps, you can look forward to the flourishing growth of your transplanted ferns, ready to unfurl their fronds and bring a touch of green serenity to your outdoor space.
