I'm about to head off on Vacation for ten days and am worried my plants will wilt and die. This made me think an app to take care of your plants would be great for people in situations where they aren't able to get on the game and take care of their plants. We have Grub Guardian which lets you train your pets from wherever on your phone and it'd be nice to have something similar with plants.
Your plants will not die. And other people have suggested implementing a gardening app too. However, again, your plants will not die. You are fine. Have fun!
