Or is it infinite? I've harvested up to 2 on one of them...

I believe that it is until you decide to destroy the plant or you need to remove the plant pot (when you buy a new home) you can keep harvesting. Just remember to water properly so the grade doesn’t drop.

If you buy a new house you will be starting again, so it is a good idea to remember to have your chosen fertiliser and seeds ready if you are planning on buying a new house anytime.

Harvesting time depends on which plant you have. I’m still waiting for my first harvest from my dragonfruit cactus for example, but I have already harvested twice with my evolution plant.
