If only the plants have been harvested on a chunk nothing respawns currently.

If you literally ‘only’ gather surface resources and never place or modify other blocks, then a current issue is that this wont trigger regeneration of the chunk (as nothing has changed to be regenerated) which also means resource regeneration which occurs as a result of regeneration wont trigger also. That’ll be fixed in the near future, but for now… mine a block in the chunk, and resources will regenerate along with it.
