I have been clearing about 1.5 acres of forest over the winter for the bees (new beekeeper started last year, get the bees established first and then put in the orchard – everyone is happy). Over the past few weeks, I have cut down a number of ash and hickory. The sap bleeds out of the stumps and my bees have been having a field day with the sap. Is this the same as sugar water to them? I know I should have taken a picture but there were about 75 of them on one stump ~ 12 inches in diameter last week.
The sap of trees is similar to a sugar syrup and in its original form bees will take it if and when readily available. Some would consider it a honeydew, being from the sap of the tree. But the bees are harvesting the "sugar" content just as they do from flower nectar and converting it. Sap has higher trace mineral content than sugar syrup.
