How can I stop the spread of ostrich ferns?

Question

my beds are being overrun by ostrich ferns choking out rhododendron, etc. How can i limit or remove?

Answer 1

They reproduce by spores and spreading underground rhizomes so you can be vigilant and remove the fronds with spores. Other plants can be dug and given to friends or donated to plant sales by area nonprofits.

If you decide to remove the whole group, an herbicide might be helpful. If you decide to dig up the whole clump, be sure to get all the rhizomes you can.
