Sorry Tilly your last post wasn't there when I posted my query!
If you have clay soil and are now watering quite a bit - especially with the tube system - it may now be sitting in water If so you would need to improve the general drainage where it is by adding grit and a bit more compost to the mix in the hole and replant. Obviously you'd have to lift the tree out to take a look and see - sorry if I didn't make that very clear.
Oh forgot to say, Garden centre tree expert suggested not to dig tree up and then replant because may cause more damage, but to treat tree in its present situ as growing season is in full swing. Will consider replanting in late Autumn and improvin soil area, that is if tree still alive! Oh dear what a bother I have ended up with!
