Thank you for the replies Brooklyn1 and songbird...much appreciated.

I am located in central Scotland,UK. The inclement weather here can affect planting and growing times.

As I have limited space, I decided to buy 2 dwarf apple trees and are presently in containers. The variety of both trees is 'Jonagold', which were bought and planted on the same day only a couple of feet apart. As I said, one is growing healthily and the other has curled up leaves. This is what leads me to think one is diseased, or am I on the wrong track?

Thanks again, folks.

Regards,

Dunli
