You're growing a mango tree in Canada??the mango is such a tease. it's growing a leaf; that's pretty clear. but the whole thing is basically like a huge bean, so it's doing that thing where first you get days' worth of only the stem sticking up in a loop, before the leaf finally breaks out and stands up. based on the size of this seed, by the time that stem is strong enough to lift it, we could be back into winter clothing.
