As a warning though, Repel IS made from extracts found in the piss of dragonite and other powerful pokemon. So your plants will smell slightly of urine.
For a natural alternative, see if you can't park a Torterra. You'll need to make space but Torterra are great at HELPING soil quality if there's another source of food around... Like, Oddish.
