Re spawning foliage

Hello, I have some foliage that I can cut down like tree or plants(survival Game), but as they are foliage I don’t know how to respawn them.
Example, players cut tree, after 2 hours he comes back and it is back.
I know how to make it work actor but no as a foliage.
Anyone know how? Thanks for any help.
