Thank you for the replies - to answer those who in turn queried - we live
in Edinburgh,Scotland and have not had the soil tested;do not think the
tree has a name,as I said it is a hybrid with 3 different types of
apples,1 cooking the other 2 eating and it does flower at more or less the
same time as the other one but they do not flourish to fruit and finally I
do not feel we are pruning too hard.
So as you can see quite a problem!
