We invite you to visit... In 1880 the site that was to become Glenwood City was a tranquil glen (valley) in the midst of huge forests. By 1885-1890 with the coming of the railroad and the lumber mills, Glenwood was the major trading center of the area with a population of 2000.
English walnut trees can be tapped successfully, especially when subjected to a freezing winter and spring. Paper birch (Betula papyrifera) The paper birch has a lower sugar content than sugar maple (less than 1%), but is the sweetest of the birch trees.
(Source). To protect the treeâs health, do not put taps in any tree smaller than 10 inches in diameter. Over-tapping harms the trees; under-tapping reduces the sap yield without doing anything positive for the trees. A commercially profitable sugaring business should have 70-90 taps/acre and 20+ acres of woodland.
