Comprehensive video on how to make the most of your sugaring season, covering tapping, tubing, and efficient boiling.
Keys to High Yield
Actual yields in many maple operations are often lower than those achievable under optimum conditions. Dr. Abby van den Berg, Research Associate Professor with UVM’s Department of Plant Biology and Proctor Maple Research Center, presents practices to narrow this gap, from tree to sugarhouse.

Lecanium Scale: What A Sticky Mess!
If you have a sugarbush in the Northeast, you may have noticed brown scale insects, sticky dripping honeydew, and black sooty mold on your sugar maple leaves in 2005 and 2006. That most likely was European fruit lecanium scale, Parthenolecanium corni.
Limitations in the Use of Ozone to Disinfect Maple Sap
This article reports on experiments to determine the usefulness of ozone as a method of reducing the microbial levels in maple sap.
Long-term average a better predictor of air temperature
Short and long-range weather forecasts can both be useful to determine the proper time to tap. But both also have limitations.
Long-term calcium addition increases growth release, wound closure, and health of sugar maple (Acer saccharum) trees at the Hubbard Brook Experimental Forest
We surveyed and wounded forest-grown sugar maple (Acer sacchamm Marsh.) trees in a long-term, replicated Ca manipulation study at the Hubbard Brook Experimental Forest in New Hampshire, USA. Plots received applications of Ca (to boost Ca availability above depleted ambient levels) or A1 (to compete with Ca uptake and further reduce Ca availability). We found significantly greater total foliar and membrane-associated Ca in foliage of trees in plots fertilized with Ca when compared with trees from Al-addition and control plots (P = 0.005).
