Hello all - new here. I'm in central Maryland. I recently planted a few ferns from a local nursery - cinnamon, ostridge, christmas. I planted them in small alcove garden with a bench, pots, rocks, stone path, etc. My sister, who lives in Pittsburgh, said take the ferns out; she had terrible trouble with invasive ferns (not sure what type). I'm thinking of installing some landscape fabric/light much under an adjacent wooden deck to avoid some trouble. Is that enough? Will I regret the ferns?? Thank you! Happy gardening on this lovely Saturday in June! Jul Smiling

Welcome! Welcome! Welcome!

Your sister is partially correct. Ostrich fern, matteucia strutheropteris, can become invasive if it likes the location. But it is easily controlled.

Christmas and cinnamon fern spread very slowly. I have ostrich,Christmas, cinnamon,sensitive,wood and a few others. The only one that requires regular herding is the ostrich.

Landscape fabric will only encourage the ostrich to spread further as it will travel under the fabric until it finds a weak spot or hole to poke through.

Mulch will help retain moisture and nourishment as it breaks down.

hi! Welcome!
yes, Ostrich spreads in my yard, maybe a new shoot a few inches away each year. Not too hard to dig up.
Sensitive fern(aka bead fern/ Onoclea) ( you did not name) also spread for me and becomes a thick mat of roots, more like a ground cover of fern. Harder to dig.

Landscape fabric won't stop any and makes its own problem. Mulch won't block these ferns as they come from wandering roots.

I don't know that you have to worry about them going under the deck, the ostrich that is, as they won't grow that well in darkness under there.

we use a layer of stone under our deck. It gets dirty eventually but is brighter and drier than mulch.

Wasn't it just gorgeous this weekend? Hurray!
Plant it and they will come.

Thanks Sally. I couldn't remember the sensitive fern name. Mine are pretty much staying to themselves. Of course, now that I've said that ...

Well, the sensitive fern doesn't travel fast but it is pretty solid mat when it goes, unlike Ostrich fern sending out one runner and a new rosette at a time in my few years experience anyway.
Plant it and they will come.
