I posted a few weeks ago and should have started its own thread. Any opinions or ideas are appreciated. Thanks.

I was hoping for a Dr. Perkins response in regard to these situations.
I checked a whole pile of smaller trees today and have some questions. Everything was in the 2-7 inch. I probably did at least 300. Froze real hard the past 2 nights and took the oppurtunity to do this. I ran into a few larger trees that had full blown leaves coming on, small, but leaves were there. Those few didn't run that much and the test was below 1%. Are those trees so far advanced that the sugar test would be way, way off compared to if they did not have leafs on? In other words...what I am trying to ask, was it too late to be comparing trees with small leaves, compared to say a neighboring tree with no leaves. Did I not get a good represenative comparison compared to doing this in the winter or normal sap season? Once the leaves hit, does the sap sugar just completely bottom in those trees compared to a neighbor with little or any leaf start? And therefore would be unfair to those leafing out trees?

I was quite disappointed at the number of beautiful nice shaped trees that I had previously thinned around since 1998 and the sugar test was way bad. On the flip side, I was running into an equal amount of crappy trees, forked trees, doubled at the bottom, etc that were some of the highest testing ones out there. Its quite disappointing, to think I would have cut those down first had I not sugar tested. So do I cut the real good, picture perfect, low test trees down and focus on the releasing the crappy high test ones that will probably not last too long because of forking, cankers, etc? This is a tough call to make.

The sugar range of everything I tested was between .7% to 2.9%, one tree made 3%. I am thinking if this were done during a normal sap season, the sugar would be 1 to 1.5% higher across the board.

I ran into 2 clumps of red maple next to some nice sugar maple and in both cases the reds were a whole percent higher than the sugars. The clumps had about 3 stems each. It will feel pretty silly cutting the sugars down to emphasize the reds. About 5% of the trees I tested were reds, only about half of the reds were running though.

One last question, what works good for permanantly marking these trees %? I used black marker and a little white spray paint, (all I had) and one ribbon to mark those over 1.5% and 2 ribbons for anything over 2%. I have seen alum, tags somewhere? These trees need to be marked for the long term, I'm not doing it again.

Mark, that's a pretty technical question. I would PM or email Dr. Perkins with your question. For tree marking, I'd get a couple of different colors. One color for a given sugar content range another for cull trees, etc. Just a small mark and you can see what the tree is from a distance.

First thing I would do is go through and cut all the cull trees. All the ones that have damage or are leaning etc... then I would probably know that I would keep the 7 inch trees over a 2 in tree, thereby I would cull those trees that were too close. Then you would have fewer trees to worry about. make your job easier.

i don't know Thad, would you really want to cut down a 3% 2" tree standing next to a .5% 7" tree? There are at least a half dozen spots where this is the case. that is why I was really questioning about the growth status screwing up the sugar %. In many cases...the larger trees appeared much farther along with leaves than the smaller ones on the day I performed this test.

You need to test them more than one. I tested a nice tree and it came out at .7 where all the rest were testing 1.7 all around it. later in the season that tree tested 1.9 and all the rest were at 1.2. So test it again early in the season next year and see where its at.
