Winter Care for Kimberly Queen Ferns

We have 9 Kimberly Queen Ferns that we have potted and keep outdoors. We let them die out in the winter and replaces them in the spring. We would like to keep them alive over the winter and want to know how to do that. We are going to put up a portable green house to house the plants in the winter. Will they be okay in the pots they are in or do we need to put them in larger pots. Is there anything special they will need in a portable green house, grow lights?heater? Any advice greatly appreciated.



Hi Phillip,

Kimberly Queen ferns thrive in temperatures between 60°F-70F° (15.5°C-21.1°C). They can tolerate temperatures as low as 40°-50°F (4.4°-10°C) for a few hours. I would try to keep your greenhouse 50°F (10°C) or above it possible.

Repot to the next size pot when the roots have filled the existing pot. Ferns do well when root-bound so do not rush to repot. Do not fertilize a fern for several weeks after re-potting. The best time to repot is in the early spring.

A Kimberly Queen fern does well in medium light. Avoid placing it in direct sun or the color in the leaves will fade.
