Matteuccia (ostrich) Fern Frost Damage

Asked May 18, 2016, 5:14 PM EDT

Hello, My backyard has many ostrich ferns that appear to have been affected by the recent frost Sunday morning (5/15). The fronds were unfurling when the frost hit and now many appear wilted and "zapped" by the frost. Do you know what I should expect from these? Are they dead? Will they produce new fronds this season? Go dormant this season? Or something else? Thanks. Michael

The ferns are not dead and they will produce new fronds this season. However, this year the fronds might not be as tall and dense as they usually are.

Thanks for the response Bob. That was the answer I was hoping for!
