Orchard notes and map

Trees were initially planted in April of 2013. No rootstock information is available. Observations from a site visit in spring 2019 indicate that trees have signs of fire blight, deer damage, and are in need of pruning. A couple of trees have fallen over, and most are dead or dying. However, ‘Goodland’ apples were still producing; orchard managers harvested a small basket of big red apples the previous season.
