My trees are 'wood lot' trees with long trunks and compact tops, sort of lollypop shape. So the sugar content is not real high but they do produce a lot of sap. I am still cleaning up blown down pines so I need to burn up the wood anyway. Larger trees take a little bit longer to thaw out IMO. When they start running so will you. I have a few that fill 5 gallon buckets in one day!
Starting beekeeping? I am on my second winter. Lost 2 of my four hives to starvation. I have mixed emotions, I want the trees to bud out for the bees but not to bud out because of maple sugaring!
