I think all major gardeners know that when you have a huge garden of EMPs or Couch Potatoes, it takes a lot of time to plant each of them. What I'm suggesting that KI should add is a mass-plant gardening spell. This would ease the burden of each and every plants, taking time and time to be planted. This would be sort of like the Mass-Gardening Spells, like, rain for a certain amount of area for 15 energy (Downpour).
Oh, there's already a spell like that, it's called "Plant All", you can buy it when you reach level 15 on Gardening, the NPC is located in Avalon. It costs a "x" amount, you cast your seed on a plot (say Couch Potato) then you cast this "Plant All" spell, it will then plant all of your Couch Potatoes on the available plots. The quantity will depend on how much energy you got plus available plots/seeds.
