Hadn't been up to the furthest zone (forest) in some time. Preparing to put pigs here, due to the tall grass in some areas. But I'm curious, what do a significant amount of daisies mean ? How about a rocky bottom, can I build soil on top of this? What would you grow here? What are these purple flowers, and tall looking plants? Does this mean high or low ph? Not sure what to make of what I am seeing, though I am intrigued by it (a month ago this was all bare). How does a Permaculturist, or someone "in the know" interpret this?
