Crowding out poison ivy or laying sheet mulch on top - anyone ever try this?

Hi! I am wondering if crowding out poison ivy with other strong perennial local indigenous plants could counteract them coming up and growing in a shady area, even if I don't physically yank them out.

Another idea that came to mind would be to cover the patch with cardboard and lay a sheet mulch over top of it for at least a year to later transform it into a ''safe'' growing area for other painless companions to grow instead..

Has anyone ever tried any of this and if so, what was your experience and observations?

Many thanks and best of prosperity in this time's growing experience!

Hi Anna, I've had good success with "spot" sheet mulching when poison ivy pops up in my forest garden.  Usually I just mat wet leaves down over the plant and then drop a small pile of wood chips over that.
