magnolia tree

Hello - would anyone happen to know the symptoms of a dying magnolia tree..It was doing so well back in the spring but now its leaves are starting to blacken.

The green of the leaves looks like there is a hue of black 'inside' the leaves colour. (i.e its not a powder growing on the leaves - its the pigment has actually changed.)

I had a look around the base and it seems as those fine roots are actually coming up through the earth. I've got a feeling there isn't enough soil where we planted it and the roots are actually of the trees.

We planted around May - do you think it will survive if I try and move it to another spot in the garden? Does anyone have any advice re moviing trees.

Many thanks..

 

What is the soil and aspect like? Also what type of Magnolia is it? It isn't unusual for the roots to show above the soil, you can mulch them if you want to (ericaceous compost or well rotted leaves). Are the leaves wilting as well as discoloured? Do you have a picture?
