Hi Guys
I planted 3 "Pyrus Cleveland Select (Ornamental Pear Tree)" about 6 months ago which were doing great in pots beforehand. However since I have planted them the leaves started to go a little bit "crinkly" and brown around the edges. Now some of the leaves have gone have deep black and some parts yellow, It only appears on some parts of the plant (the black) but it looks awful. It appears to be struggling. Any ideas what it could be and how to treat it. (I will take photos and post soon). My brother in law said it could be a fungus or mould. Help!
Thanks
