All fruit growers need to be philosophical. It's best never to expect anything other than just a pleasant tree to look at. If it does give you some fruit in Autumn, just be grateful. If you are counting on fruit, you will more than likely be disappointed.
There are some exceptions to this rule. Our Bramley (above) is pretty regular. It would be a strange year to have no crop (as with the Fig and Quince trees that always bear fruit).
This Jonagold (above with Bok) was planted quite recently. It bore some fruit last year, but this year hasn't a single flower on it. I'm not very happy.
In the chicken run is this Reine de Renette which occasionally does well. The hens peck at anything that drops; we have the rest. Nice apple; quite similar to a Cox.
And, meanwhile, this is the state of affairs at Haddock's. Everything doing OK, the Tomatoes are still untouched by frost, but I'm not uncrossing my fingers just yet (I've noticed other local gardeners being equally foolhardy).
We've just had a short spell of overnight rain, so now everything is romping; including the weeds.
