I just don't get it. We've had some ideal run conditions (mid 20's at night to mid 40's and 50's during the day and the only trees that ran were by the swamp. This week we hit 60-70 degrees during the day, mid to upper 30's at night and the swamp trees had only a few ounces but found 3 trees in the woods with 1/2 gallon or better in them. I have 200 trees tapped altogether. Low lying, South facing hillside, North facing hillside and flat land trees. I'm only making 1 gallon of syrup at a time so the sap won't spoil. Heck, if the bag has 2 ounces in them, it goes in the bucket to boil.
If nature's recharging system isn't working, I may resort to electrical means.
