Lowest sap sugar % ever

[Russell Lampron]

Curious as to what you call red maple vs swamp maple?? Acer rubrum? Red or swamp maple

They are both red maples. The ones that I call swamp maples are the ones that are rooted in the water.

Mine has been exactly like yours. I started around 1.8% like you and did a boil yesterday that was 1.4%. I've never seen sugars that low here in Union County Ohio. Almost all of my trees are sugars.
