White Tree rot?

Asked May 8, 2020, 1:53 PM EDT

This is 100 year old mulberry tree, the other day I noticed this white stuff that looks like paint or frosting, i whenI touched it part of the tree trunk just crumbled, the rest of the trunk now seems solid but there is this big gaping whole in the trunk. I’m worried because there is more white stuff, is it killing the tree, Is there something to treat it

That is exactly what we call it, White Rot. As opposed to brown rot as a wood decay. There are several fungi that can get into wounds and decay the heart wood away. It takes a long time and your tree may live many more years. It is not structurally sound and could have problems in ice or snow storms or unusually heavy winds. Have a look at these two web sites and read more about it:
