Hello everyone.
I have a question about my white mulberry (Morus alba): Does the crossection of the trunk looks ok, or does the discoloration in the middle indicate some disease (this is a cross-section of the trunk after pruning, trunk thickness: about 2 cm, cut at a height of about 160 cm).

Those appear to me to be standard xylem phloem cambium layer colorations for a mulberry tree. I’ll try to get a cross section picture of the mulberry that I’ve had to top at my property the next time I am there.

Thanks for the reply. I think that when I cut another mulberry of the same diameter, it didn’t have a brown core. But maybe it was a bit thinner than this one and that’s why it didn’t.

It appears normal for a 4 or 5 year old Alba. As it grows larger the heart wood (dark spot in the middle) will continue to grow larger. By about year 15 or so the heart wood will take up more area than the lighter (sap wood) ring on the outsides.

I was able to get pictures of not one, but two mulberry trees which suffered recent damage and were trimmed as a result.
