I recently repotted my fern and now it is turning yellow. What am I doing wrong?
Asparagus Fern do prefer to be root bound, so repotting is done generally every few years.
Make sure you only went up 1 pot size. Too large of a pot could cause root rot.
Yellowing of leaves is most likely a watering issue, too much or too little.
Here is an article that will help refresh you on the care requirements.
