Apples trees dying

[jennym]

I'd say that they should be re-potted, preferably when they are dormant, in winter, into pots at least 2 or 3 times the size you have now. They won't flourish in what is essentially a cubic foot of soil.

Get the biggest containers you can, and give them new compost; do it around October. how much light are they getting where they are?

They are in the shade a bit our back garden is north facing and they are in a corner to protect them from the wind.
