As the chill in the air begins to settle in, it’s time to think about protecting your precious ferns from winter’s bite.
Many people hesitate to bring their ferns indoors because of the mess.
However, with a few quick steps, you can keep them gorgeous all winter long and ready to thrive again in spring.
Overwinter Your Ferns Like A Professional Gardener
1. Know Your Fern: Tropical vs. Hardy
Before winterizing, it’s essential to know your fern type.
Tropical ferns, like Boston or Maidenhair, need to be brought indoors before the first frost, while hardy ferns, such as Lady or Christmas ferns, can often survive outside with a bit of protection.
Knowing this helps you apply the correct care, ensuring a smooth transition through winter.
2. Move Them Inside Before Frost Strikes
Ferns are resilient, but frost can cause significant damage.
If your local weather tends to be unpredictable in the fall, like it often is in Eastern North Carolina, be proactive. Keep a sheet or blanket handy to cover your ferns on those unexpectedly cold nights.
This gives you more flexibility before making the final decision to bring them indoors.
3. Give Your Ferns a Good Rinse
To prepare your ferns for indoor living, take advantage of a warm day (60°F or above) to thoroughly rinse them off.
Focus on the undersides of the fronds and deep within the plant to eliminate any lingering pests or debris.
Allow the ferns to dry out completely before relocating them indoors, which will help reduce the mess.
4. Shape Up with a Gentle Trim
While there’s no need for heavy pruning, a light trim can make your ferns easier to manage indoors.
Remove any overgrown or straggling fronds to keep the plant tidy and compact.
After trimming, give the plant a gentle shake to dislodge any remaining leaves or debris, ensuring it’s in top shape before coming inside.
5. Find a Cozy Winter Spot
Choosing the right indoor spot is crucial for your ferns’ winter survival. Opt for spaces like basements, garages, or a cool corner in a room that offers moderate, indirect light.
Keep them away from direct sunlight, especially from southern-facing windows, to prevent the fronds from getting scorched.
6. Minimal Care for Maximum Survival
During winter, your ferns will enter a period of dormancy, meaning they won’t need as much attention.
Water them sparingly—only when the topsoil feels dry—and hold off on fertilizing until spring. If your fern begins to look a little pale or sheds some leaves, don’t panic; this is normal.
To combat excessive leaf drop, increase humidity by placing the pot on a tray of gravel filled with water.
7. Outdoor Winterizing for Hardy Ferns
If your ferns are staying outside, mulching is essential. Apply a thick layer around the base once the ground begins to freeze to insulate the roots.
After the first frost, prune dead fronds back to about 2 inches above the soil, directing the plant’s energy to its roots.
In regions with harsh winters, consider covering the ferns with breathable burlap or frost cloth to protect them from extreme cold.
8. Beware of Late Spring Frosts
When the weather starts warming up in the spring, it’s tempting to move your ferns outdoors for some fresh air. However, be cautious—late frosts can still pose a threat.
Keep an eye on the forecast and be prepared to cover your ferns again if needed.
Common Winterizing Mistakes to Avoid
- Overwatering Indoors: Ferns prefer slightly dry conditions in winter, so resist the urge to water too frequently.
- Skipping Mulching: For outdoor ferns, mulching is critical to protect the roots from freezing.
- Ignoring Indoor Pests: Bugs can be a hidden problem when ferns move indoors, so inspect regularly and treat as needed.
