When I give water or music to my couch potatoes, I can cover a maximum of two plants at a time.
Aren't there spells that would let me cover more plants at once? How can I get them?
It sounds like you've somehow missed getting your large area spells
You can get them from Marley (Jade Palace - Mooshu) or Harley (Base Camp - Celestia). If you're unable to enter those areas yet you will need to port your gardener wizard to a friend there.
Note that is worth going to BOTH since they have 1 spell each that the other doesn't. Marley has medium enchanted soil and Harley has pungent bug spray.
