frozen buckets on trees

[maplefarmer]

My buckets and bags are frozen solid on the trees, we didn't have a big run to fill them, they seeped over a couple days and filled and are frozen.

The best results boil and collect every day whether its a lot or only a couple of gallons this keeps sap fresh and light color.won't have to worry about spoilage.
