Help! I have an Apple Tree in a city courtyard that's about 5 foot high in a pot about 2 feet high by 2 feet in width. It's been in this pot for approximately 3 years. Last year it produced between 15 to 20 apples.
This year after a lot blossom and producing many baby apples, it suddenly changed and in the last few days at least half of the leaves have turned bright yellow and have started to fall off.
I have sprayed it with an organic spray and fed it with Organic Fertiliser to no avail. It seems to be crying out for help. Do you have any idea what could be wrong with it and what I can do to save it?
Many thanks, Jo.

You'll also be able to see if the root system is healthy or being attacked by something.

id be inclined to gently slip it out of the pot and see if its root bound and if so repot it up into a bigger pot .
