Should I cut brown leaves off asparagus fern?
If the occasional leaf (needle) on your Asparagus Fern is brown, then leave this alone. However, if a large chunk of a stem is brown then remove this part. Once the stems are brown, there’s no bringing them back to green, unfortunately, so removing them will allow your plant to focus energy on new healthy growth.
