One Tree with Nothing

[optionguru]

My taps are finally starting to have a real run today. They actually started a little yesterday. I currently have 40 taps in and one of my three rockstar double tapped huge sugar maples are doing nothing as in 0 sap. What would cause this? All three of these large trees are in a line on the same hill side with the same sun exposure.

It's the female tree and doesn't want to cooperate?

[happy thoughts]

It's the stubborn male tree that won't ask for directions?

Taps on the north(cold) side of the tree????

[happy thoughts]

Are they all the same diameter? Are the tap hole depths equal? Is each tap the same distance from a previous tap hole?

I have a few trees that have never gave me a drop of sap, But I tap them every year hoping this will be the year. Trees 10ft away will give a gallon or more a day.
I'd love to know the answer.

If you find the answer please share it with us. 375 taps made me almost 25 gallons of sap on this fine day

I had over 300 taps last year and on my best day I would get 35 gallons. I went to vacuum this year, hoping for a huge improvement. We'll see this weeks forcast looks good.

Well when we gathered our 400 buckets recently we came across half a dozen that had no sap:

2 maple trees were dead
1 was a brown ash tree
and 3 had the spile driven in the wrong hole. This years hole was oozing sap and the spile had been driven into last years taphole. This is related to the 3 foot snowpack and having to tap down at knee level. . .

I have a couple of Red Maples that haven't given more than a drop this year.

I have one huge sugar that has done the same thing. Not one drop and then Tuesday I checked and it was overflowing, open the bucket and its yellow sap. Had to dump it. I would love to know why this happened. I asked earlier in the season on here and never got any good answers.
