I currently have used up all of my plant slots for the time being but I need to grow a different plant. But I don't want to destroy any of my plants, because they take a while to grow.
And when I was moving my stuff to my new house recently, I came up with something.

You see, you can put potted plants in your inventory.
So, theoretically, you can switch out one of your active plants with a new plant pot and plant a different plant without destroying the old one.
However, I don't know if the plants moved in your item inventory will wither or lose their grade when you don't water them (since they aren't in an active slot).

If anyone has any idea if this would work, it'd be appreciated! I'll probably end up doing it anyway, but I'm curious if anyone has done this before, and it'd be reassuring to know.
Thanks for reading, and have a lovely day!
