Man of the House

This kids Dad is working in the states. That makes him the man of the house at eleven years old. He is hilling his family potato field by himself. The soils look beautiful to me but there is a bag of synthetic fertilizer next to Cruzs sister. Perhaps it is some micro-nutrient deficiency that disallows the crops to yield like they used to. They told me that they like to eat the greens off the potato plant; which surprised me. But only the "crioyo", or heiloom/local varieties. This confused me and needs more attention. Why not eat the greens from the new varieties? It is my understanding that the nightshade family potato plant is poison; excepting the tubers.
I've had bean greens and squash tip greens so far on this trip and they where both delicious. It is good to be out in the world seeing a bit of whats new and old.
