The winter season brings many changes to nature, and one of them is the challenge of surviving in colder regions. Plants, just like animals, have their own strategies for surviving the cold season. For example, some may go dormant while others may die off altogether.

However, one question that many gardeners and plant enthusiasts have is whether or not ferns can survive winter. The answer is that it depends on the type of fern and the conditions in which it is growing. In this article, we will explore the ways that ferns survive winter and provide tips for helping your ferns thrive during the colder months.

The good news is that many ferns are able to survive the winter season. While some may go dormant, others can actually thrive in cold temperatures. Ferns that typically live in warmer climates may need a bit of extra help to make it through the cold months, such as being kept in a greenhouse or sheltered from extreme weather conditions.

Ferns have adapted to their environment

Ferns have evolved over time, and certain species have adapted to colder climates. These species tend to be hardy, evergreen plants that can tolerate freezing temperatures and light snowfall without any damage. Some common cold-tolerant varieties of ferns include:

  • Maidenhair fern
  • Christmas fern
  • Ostrich Fern
  • Japanese Painted Fern

If you’re growing ferns in your garden, it’s important to protect them from extreme conditions. If the temperature drops below freezing, cover them with a tarp or blanket and make sure they have enough moisture during the winter months. Some people also recommend mulching around ferns to help keep their roots warm.

Types of Ferns and Their Cold Tolerance

Ferns are found on every continent except Antarctica, and they have adapted to a wide range of climatic conditions. As a result, there is a great deal of variation in the cold tolerance of different fern species. Some ferns are native to cold, temperate regions and are able to withstand freezing temperatures and snow, while others are native to tropical regions and are not cold-hardy at all.

Some examples of cold-hardy ferns include:

  • Ostrich fern (Matteuccia struthiopteris)
  • Christmas fern (Polystichum acrostichoides)
  • Wood fern (Dryopteris spp.)
  • Royal fern (Osmunda regalis)
  • Maidenhair fern (Adiantum spp.)

On the other hand, tropical ferns that are not cold-hardy include:

  • Bird’s nest fern (Asplenium nidus)
  • Staghorn fern (Platycerium spp.)
  • Fishbone fern (Nephrolepis spp.)
  • Boston fern (Nephrolepis exaltata)

It’s important to note that even within a species, there can be variations in cold tolerance. For example, some varieties of Boston fern are more cold-hardy than others. In general, it is a good idea to research the specific needs of the fern species you are growing to determine its cold tolerance and how to care for it during the winter months.

Protecting Ferns from Cold Weather

If you live in a region with cold winters, there are several steps you can take to protect your ferns and help them survive the winter:

  1. Choose the right location. Ferns prefer moist, well-draining soil and partial to full shade. In colder regions, it is a good idea to plant ferns in a location that is protected from strong winds and direct sunlight. A north- or east-facing location is often a good choice.
  2. Provide insulation. Mulch around the base of the fern with a layer of straw, leaves, or wood chips to help protect the roots and crown of the plant from cold temperatures. Be sure to keep the mulch about 2 inches away from the base of the plant to prevent rot.
  3. Water regularly. Ferns need a consistent supply of moisture to survive, so be sure to water them regularly throughout the winter. Avoid letting the soil dry out completely, as this can cause the plant to go into dormancy and become more susceptible to cold damage.
  4. Protect from freezing temperatures. If you live in a region with extreme cold and snow, consider providing additional protection for your ferns. This can include covering the plants with a layer of burlap or other fabric or using a frost blanket or plastic sheeting to create a miniature greenhouse effect. Make sure to remove the coverings once temperatures rise above freezing.
  5. Provide extra nutrition. If you are growing ferns in containers, consider fertilizing them every month or so during the winter months. This will help give them an extra boost of energy and help them stay healthy throughout the season.

In conclusion

Overall, if given proper care and protection, many types of ferns can survive the winter season. Cold-tolerant varieties are especially well-suited to colder climates and may even thrive when temperatures drop below zero degrees Fahrenheit. With some extra TLC and attention to detail, your ferns should make it through the coldest months just fine.
