Title: Yellowing fern houseplants from Lancaster PA
Answered by: Barbara Medford

QUESTION:

I have fern houseplants about 9 to 12 months old and they are turning yellow. I don't overwater and they get good light. They are growing well but I don't understand the yellowing and falling off! Hmmmm??? Do you have any answers?

ANSWER:

Mr. Smarty Plants is not too smart about house plants, because they tend to be non-natives that can withstand the stresses of living indoors. There are some ferns native to North America, which is where our interests lie, but not many. First, we suggest you read our How-to Article on Container Gardening with Native Plants. Even these are generally meant to be grown outside in the climate, soils and rainfall usual to which the plants are native. So, let us point you at some websites that can better address your situation:

University of Vermont Extension: Growing Ferns Successfully Indoors

Guide to Houseplants: Types of Ferns to Grow Indoors

University of Rhode Island Indoor Ferns

Turns out there are actually 66 ferns native to Pennsylvania, so we chose some for you to look at, in the interest of preserving our advocacy for native plants. You will note from the pictures that they are all shown growing in their natural state outside, so we don't know how any of them would do as indoor plants.
