dead apple tree?

[YFS]

Hi

I have a shop bought apple tree that has been in the ground for over a month, maybe 2, and there is no sign of buds.
Other trees were planted at the same time and are doing ok, the tree without bud did look different, but its green under when i scratch the bark; does that mean that i should just wait.
I bought 6 from different places, the 'dead' one was from B+M, all the others are starting to leaf up.

If there's green under the bark then I'd wait a bit longer. If it was a bare rooted tree then it will need lots of water.
