Decided to go out and dig up one (1) jicama vine today. Did so and harvested seven pounds of dirt-free (I washed them) jicama root. I shudder to think what lies under the other 7 vines. They weren't all nice little balls like you buy in the store, some were elongated like sweet potatoes, and others were huge lumpy things. Now I gotta figure out how to eat or give away all of this before they a)rot, b) start growing again. I had no idea I could grow such huge jicama root in one season here in Zone 9b. George
