When you bring a Boston fern in for the winter, don’t move it from a chilly porch straight into a warm living room.
That sudden change can shock the plant, causing leaf drop or yellowing.
Instead, plan to bring it inside on a mild day when outdoor and indoor temperatures are somewhat similar.
A gradual transition is key to successfully bringing Boston ferns in for the winter.
3. Start the Process in Late Summer or Early Fall
Many gardeners wonder how to bring a Boston fern in for the winter without stress.
Starting in late summer allows you to adjust the fern’s environment bit by bit.

This slow shift prepares the fern for lower light levels indoors and is a common tip for how to bring a Boston fern in for the winter.

2. Trim Away Dead or Damaged Fronds

Making small tweaks early on helps your fern settle in quickly.
Monitoring your fern closely is part of mastering how to bring a Boston fern in for the winter.
