Why are my Espalier Tree's not Fruiting?

Thank you. They come every year. So just keep cutting them back?

Was wondering whether there was anything that could be applied to the cut face to stop regrowth. Without damaging the tree

Each one is a new sucker, so applying something to the cut face of old ones won't stop them popping up. So yes, just keep cutting them back whenever you see new one.

The suckers are very interesting; M9 is notorious for producing lots of suckers, and also needs a pretty decent soil to grow in, so my suspicion is that the apples are grafted onto that. I've got a Telstar (yes, named after the satellite) grafted onto M9 in my back garden that's getting on for 10 years old and it's never really taken off - I blame the rootstock, which I was warned would not be vigorous enough for my heavy clay. Live and learn, as they say.

Evening all. Reviving this thread as I was out doing some early spring work in the garden and was shocked at how much the fruit trees had grown over the winter. They were all trimmed back to the height of the fence at the beginning of winter, and as you can see they are well above that now!

My plan following the advice of others in this thread is to feed with BFB early April.

But I am wondering if I should trim them all back again to fence height, or just leave them until early winter again?
