My gardenia has already fought spider mites months ago. Now, some leaves are bitten off, and the general "there's spotty stuff on the leaves" look is back. (Proceeds to spray plant with heavy pesticides).
The very same day, a minirose (keep in mind they are both outdoors and in pots) had about....75% of it's leaves munched on. Grey spots are everywhere any will turn into holes.
I want every insect within five feet of these plants turned to dust. How do I do it?
