I wouldn't bother. There will be very little fibre and mostly juice which will make your compost very acidic which will upset the balance and deter the tiny red worms from helping to break the compost heap down. Just my personal view, I can't understand why people leave their fruit to drop and rot when they could give it away if they don't want it.

Why not make apple pie?! Then invite me over. :)

Agree with Jimmy - apples ferment anyway, rather than rotting down in the same way as other ingredients on your heap. Wasp magnets too, leave 'em where they are Hank, unless you want to cook some, if you don't mind them not being the best cooker of all (bramleys)

Ok guys, thanks. We already have 120 apples stored away off my small tree B, so not short of apple crumbles which I prefer.
And it’s down to our weird neighbour to tend to his apples but he never bothers.

We have always added windfall apples to the compost heap. Hundreds of them at times. Never had any problem with doing it and they rot away nicely. Just been turning the heap and there a millions of red worms and woodlice in there along with the apples. I do tend to squish the fruit though so they rot away quicker.

Thanks OB, now I’m quite uncertain.

The horticultural advice on this is, yes,you can add windfalls to the compost heap, but cut them up or crush/ squash and mix with dry stuff like straw or shredded newspaper especially if there's a lot. Also to leave half a dozen for the birds to eat... So depends whether you want to go to all that trouble, really...

I also add them to the compost bins with little problem. lots of worms too :o)
the birds get their share too.

It's fine to add the apples to the compost pile. The extra juice won"t hurt anything. It's 90% water anyway, and sugar. A few ants may join the party. That's what they do.

Will be adding them tomorrow after crushing, thanks. Plenty will be left for birds etc.

I think it depends on the size of the compost heap. At present I have just turned over most of mine which is about 8 cubic metres. If you have one of those tiny tumbler things then perhaps lots of apples might be a problem. We try not to put them out for the birds as we find that it just encourages the blackbirds to attack the fruit on the trees earlier in the season.
Finally even if the apples are not used, they should be removed as a precaution against an increase in Codlin moth. They move out of any windfall apples that they are in, pupate in the soil and move back into the rest of the fruit, or attack the following year.
