Just three apples from my Ashmead's Kernel tree this year. Had over 100 good ones last season which is possibly the reason. It's tired out poor thing although the scientists call it "biennial bearing" and further damn the variety as "erratic".
I think it's building itself up for next year, it's got about twice the normal number of leaves (see pic) so it should have made a whole lot of sugar. It'll need a good cold winter though to make sure of a good crop. The cold tells the tree that it's really had a winter and now it's spring and kicks off the springy things like blossom. If trees had evolved wearing digital watches, it would have been simpler and, err, more digital. If you see an apple tree that does have a watch strapped to the trunk, let me know….
