View Full Version : Tapping "married" trees (mature trees that grew on top of each other)

Newbie looking forward to second season with a puzzler to ponder...
last season two of my least productive taps were in a pair of maples (or perhaps trio) that grew to maturity right on top of one another.
At first I believed them to be one multi trunk tree that had probably been cut and regrown from a stump and probably wouldnt have ever realized otherwise if I had not tapped and finally paid attention to the bark, one large 20 in dia trunk was clearly shaggy silver bark, while four other roughly 12-18 in ones clearly red. Healthy thick crowns in a wide open area behind a barn.
I proceeded to drill two holes, one in the large silver and one in the thickest red trunk. It being the first time these trees were tapped in at least ten years I just went three feet up and located the holes facing due south.
Most days these taps produced exactly zilch, on best flow days for my other trees maybe a cup to a pint from each.
Now, my theory, which I'll test next season is that my problem was that my due south location landed me at a point where the trees roots have been "strangling" one another for decades (sort of on the inside where the trunks meet).
I envision an off center ring formation in cross section of the wood with wider bands of sapwood on the outside and tight narrow bands in. I suspect that I drilled the narrow bands and wonder if that is scientifically accurate or reasonable.
I know the best advice is probably to drop the silver and perhaps several trunks of red that appear to be a third tree in the party, but my wife's affinity for the cluster that she still refers to as one tree makes that out of the question. I also cant say Im not looking forward to having something to experient with and learn from.
Any thoughts or experience about this would be great!

A couple of things. 1st, don't favor drilling on the south facing face, you should have done each on a different face, any face. If you drill all on the same face, as you move around in later years, you will then end up doing all on the north side and can get even less.
2nd, how deep did you tap and are you sure they are both maples? You should drill about 1.5" into the wood after going thru the bark, and the bit needs to be extremely sharp, both the point and the flutes. If not the hole will not flow as well. A new dedicated official tapping bit is well worth the price. Get the real thing, not just a new off the shelf drill bit, they ARE different.

Thanks for the reply! great advice on drilling location. I hadnt thought that far ahead, definitely will mix it up next season.
The holes were definitely 1.5 inches deep and the trees in question are definitely red and silver maples with healthy crowns, although a bit misleading because what looks like one big round "yard" crown is really divided by three sharing the space.
I did not use a tapping bit but will be sure to do so next year as well. today I noticed these two holes are closing up more slowly than the others as well. Same bit, same depth, same sanitation (bleach solution soak, then boil for both a new bit and taps) and while all other holes already have little wooden elevator doors closing inside, these two dont.

Don't mess around with married trees. It ain't right.

If those trees are married and there's one on top of the other I would wait 9 months and see if you get a "Rilver" (red+silver) which is a hybrid that has been known to put out. 8% sap.

Come to think of it, how do you tell if two trees are married?

By the rings

We must be behind the curve, a pair of trees married as long as we have been would have 48 rings come October, we only have 1. I guess I'm just too cheap.
