Hi all

I have a small apple tree - egremont russet I think - which is producing
fruit this year (suffered June drop or similar last year).

The apples look absolutely picture book perfect, but cutting into them shows
brown staining of the flesh.
The flesh is heavily speckled with brown, the brown being just like apple
that has been exposed to the air for an hour or more.

Anyone suggest a reason please?
Is this another symptom of the earlier dry weather this year?

TIA

Phil
