Some diseases attacked my new tree



Planted this tree in early Spring and it has grown beautifully - it really looked very nice and clean until literally just few weeks ago when I noticed a lot of brown spots on the leaves.
There is no sign of any infestation (no bugs)
There is no damage of any kind on the bark....
Is this mold or some other disease and how to treat it ?
THANK YOU !

Try doing a Google search using the type of tree and something like the words care or disease.

Plenty of water here....NJ been hot but we had some big storms and if it doesn't rain for a few days - I water it
I have not fertilized the tree but have recently spread grass fertilizer (Jonathan Green brand - few different ones) and I am sure the spreader "hit" the tree with some amounts of those fertilizers.....
Are you suggesting it could be overload of Nitrogen or Sulfur ?

BTW....this is a Tulip Tree Liriodendron tulipifera
I stopped by the nursery where I bought it..... guys said 80% it's Sun damage (just too much direct Sun exposure) but also to watch it closely and if I see more small spots - then he will give me Copper fungicide to spray it with....
let's see.....

I sprayed with Copper fungicide as it was suggested it could be mold.
but no improvement.....the strange thing is that the new leaves first appear healthy and only after a while they turn brown......
It can't be water as this is Tulip tree which likes wet soil..... I selected this particular species for its tolerance of wet soil.
I am not sure if single treatment is enough with fungicide...but may try again.

If you got it from a nursery give them a call, take a leaf in, they are probably your best source of information.

This would be a good time to consider if that is the tree you want to have there long term. Tulip trees grow to be very large and are messy in addition to being pretty suseptible to diseases especially verticillium wilt. If it is verticillium wilt it lives in the soil and there is no treatment for a infected tree other than to remove and replace it. Verticillium wilt fungus can live in the soil for years after the host tree has been removed. When choosing a replacement make sure it is resistant to verticillium wilt.
