Fireball:

• How big are these?
  
• How long does it take to create a fire ball, roughly?
  
• When you say it doesn't need to be aimed, do you mean it homes? You'd need Homing Proficiency for that.
  
• What's the range?
  
• How draining is this?
  
• Does the burning cause any debuffs (slow, loss of strength etc.)?
  
• Can this be used with other moves?
  
• I'm a little lost on how many are fired at a time. You say he can create to six but then you say they can be fired 2 at a time. Do you mean he can create 6 and just hold onto them while he fires a few in bursts?
  
  Also, the move would cost 300 OM as that's the base rate for moves.
  

As for Plant Manipulation, you'll need to buy a move for each use you're listing. So a defensive wall would be a move, roots that grip someone's feet would be a move, plant minions would be their own move, etc. Some of the stuff would also fall under powers, such as Healing for the berries.
