As for the Granny Smith apple seed that was already sprouted, it is doing quite well. We'll have updated photos up soon.
Something I have noticed so far with all our apples. They have all gone through the stratification process. Maybe not directly as seeds but definately as the apple. When we bring the apples home they go straight into the fridge. So in a few months Trevor and I will be trying a different experiment, "Is Stratification Absolutely Necessary For Apples?" In August or September we will be going to a nearby apple farm and picking apples directly from the tree. We are going to make sure they don't get refridgerated.
