Are the roots of this Mugo pine rotten?

Post by davidravioli »

Its roots do not smell foul and its cambium still remains green. The soil is well compacted but still drains really well. Here is a link to some pictures:

The white stuff is fungus: https://en.wikipedia.org/wiki/Mycorrhiza

Looks like a nice healthy root system to me!

Thanks for the reply! Would spraying a systemic fungicide resolve the fungal growth or should I repot the tree with new soil? I don't think that it is too stressed out so I might be able to repot it.

Oh whoops, I just read the Wikipedia page and it seems that the fungus is symbiotic and isn't necessarily harmful! Thank you for the information :)

I concur. White fungus on pine roots is perfectly normal as they form a symbiotic relationship which helps supply some nutrients.
While not absolutely vital for the trees -not actually needed when we supply regular available nutrients - the fungi is not doing any harm. Some people even consider it important to pine health.
