hi everyone hope someone can help I have a appletree at my allotment about 4 years old but cannot remember the name of it last year we had no apples at all this year I have apples but the bark of the tree has gone green like mildew and the apples are small and seem to have red spots on them don't want to eat them in case they are no good have a couple of pics for you to see any help appreciated

I'm looking forward to answers on this as I have a Golden Delicious tree, about 30 years old that produces a prodigious amount of apples but they are all spotted like yours and most are not much bigger than golf-balls. I was told that it was a sign of dryness of the roots (this is Cumbria for heaven's sake!) but nonetheless I piled about a foot of mulch around the base as suggested but to no avail

mine are only golf ball size as well I put that down to quite a few apples on the tree but not so sure now

I don't think there's anything to worry about, the green bloom on the trunk looks like a bit of algae or lichen starting to grow on it, which is natural/normal.  Different colourings/skin blemishes on the apples are also quite normal, particularly for home grown apples. I'd just cut them in half to check for any bugs inside, then peel them and see if they taste nice!

thanks for the reply will pick some tomorrow and see what they taste like hopefully bug free !!!!

Cut one of the affected friuts open. 

If the blemishes extend into the flesh of the fruit it could be caused by calcium deficiency.

Link here Gordino to RHS advice on bitterpit, and how to treat it. Interestingly, although the fruits are deficient in calcium, the soil itself may be fine, and the trigger is something else such as dryness. Also, some cultivars are more affected than others:

I picked all the apples today and they tasted fine some a little small and some had been eaten by pest but overall they were fine and inspected the tree and no sign of any pest on the tree

thin them heavily next year and see what results you get.
