Save Money: How to Keep Boston Ferns Alive Through Winter

“In the pursuit of knowledge, follow it wherever it is to be found; like fern, it is the produce of all climates, and like coin, its circulation is not restricted to any particular class.”

Charles Caleb Colton

Ferns add beautiful color to any front walkway or backdoor hotspot, bringing lovely long, green leaves. In the colder states, these beauties are typically tossed to the curb once late fall and winter hits, as they do not tolerate the temps much lower than 55 degrees F.

This is one reason I hate buying annual plants (plants that live through the season) because they just die off and I feel they are a waste of money; even though they are beautiful!

Did you know that even in colder climates ferns can be kept alive?

Here in the mitten, we use ferns as hanging foliage to add beauty to the porch or entry way of our homes during spring, summer and early fall, after that, most are thrown away. Sad right? Well guess what? Apparently they can LIVE through winter, they just have to be “winterized.” Almost like a boat!

These are the steps to take if you’d like to see your ferns live out the winter months.


If bringing the plant inside:

  1. The fern will need lots of indirect light.
  2. Cooler temps at night, and not to exceed 75 degrees F. during the day.
  3. High humidity (can use a humidifier).

You’ll want to prune the plant leaving only new sprouted fronds. This will help avoid a messy situation if bringing the plant inside.

Bring the plant inside and acclimate to its new climate slowly. This means bring the plant to it’s “new home” a little bit at a time so it doesn’t suffer shock.

You can also winterize a Boston Fern by keeping it in a dark area, like a garage, where the temps won’t dip below 55 degrees.

I personally will be trying this with mine, because they are gorgeous and I can not bring myself to throw them away.

Have you ever “winterized” a fern? If so, what was your experience?
