Hi there Miraians,
unfortunatelly i lost this young forest planting which i started last year.
I still don’t really know the reason why. It lost its leaves during the last summer and never really bounced back to a good health. Now, after all trees died i made a post mortem. The soil didn’t look too wet or too dry but all the roots were dead. The amount of the roots wasn’t excessive but it definitely built up a good amount of them. The only things i found in the soil were two white, clumpy spots which were quite soft:
here’s a zoom in of this spot and how it looks when you break it up:
Like i said, i just found two spots like this in the whole pot and some traces under one trunk and on some roots:
but compared to the root mass the infected parts were quite small. I can not really understand why such a small amount of a fungus (if it is one) could have such a dramatic impact except the roots were connected so strong that the fungus could infect them inside of them.
One idea is the amount of lime inside of my water. I live in an urban area and have to use tap water which is pretty hard, unfortunately. Do you guys think this could be the simple reason?
I really hope you guys can solve the problem and help me so i will learn something from this loss.
Sorry about the long post and stay safe/stay home.
