This has happened to me at least twice. I save guano for potatoes which seem to take forever to grow. Unfortunately I have lost my guano to fast growers like Rice and Spinach. When I click on a plot to see if it needs to be nourished, the guano goes on automatically if I have it in inventory. I do not get a choice to Nourish or Fertilize or even to refuse to Fertilize, the guano automatically goes on. I want an option, not automatic fertilizing. Guano is too hard to come by to waste on fast growing veggies.
