small-leaved linden

Might want to check with a gardening news group.

Well, do you know one?

There is a ring-like tissue, on the limb (look close for it), near where the limb meets the trunk. Don't cut that tissue. Cut just distal (outside) of that tissue. That tissue helps repair the cut.

If you cut that tissue, the tree won't repair itself correctly... and sometimes, when it's cut too close to the trunk, there is no repair at all.... it starts rotting, rather than repair or scar over the cut site.

Page down to the third pic, labeled 1, 2 & 3. You can see the repairing tissue just proximal to the #3 slash mark, hence the cut will be just distal of that tissue.

Sonny

No.

That was good information. Thanks for taking the time to share it.

Nice link. Not just how to do it right, but actual examples of what happens when you do it wrong. Not a lot of room for conjecture when you cover both sides.

Also, on this site, scroll down to "Further Information", there is the video "Trimming Limbs". They refer to the healing tissue as the collar. That's a better term, than my tissue term.

Also, they make note that you don't have to paint a sealant over the cut site. Painting a sealant, over the cut, may trap disease or insect issues inside the cut area.

Sonny

you are pruning because you are growing for lumber or for people nearby

if you are pruning to grow straight trees there is more to it than pruning

No, it isn't on that level, simply there is a huge tree in the middle of the area and down the stem are little branches that people get in their heads while walking by. So removing them for that and cosmetic reasons BUT not hurting the tree is the plan.

OK, so cut close, but not into the collar.

The collar tho is not that easy to spot when the branch is small and you are standing on a ladder :)

Thanks.

YW.

For really small branches, it may not matter if you cut through the collar. Really small branches may not matter, so much, for the health of the tr ee. I would take care to fine the collar if the branch is 1/2" or larger. I suppose the bothersome branches are at least 1/2" in diameter.

Sonny

The biggest I've cut so far I'd say were 5-6 cm in diameter. Then there have been many smaller, but I wonder if anyone has been as small as ~1.27 cm...

I'll bring the calipers next time :)

No need for calipers. I should have considered your metric measure. For anything the size of your index finger (there abouts) and larger, try to locate the collar.

Sonny

How do you know how big his index finger is?

That's easy. It's about the size of a branch, where you should find the collar before cutting.

My index finger is ~2cm in diameter where it is the largest so somewhat bigger than the 1.27cm mentioned. I suppose that's why it is called a rule of thumb...

It wasn't a serious question. It was related to the image I posted.
