In past years I've found timing picking quite critical; too early and they dry out before ripening, too late and the fruit is dry and prone to rot from the middle. I hope my timing is good this year as I have just picked the whole crop, a whopping 12kg (26 lbs) in one go. The reason for this is that, if allowed to ripen on the tree, they attract wasps in large number, which makes it impossible to pick the rest of the crop. I think I probably picked a tad too early, as a number shrivelled. Next year I think I'll leave a little later.
I'd been expecting large losses from pear midge this year, but the spraying was obviously effective and I then forgot to thin, meaning that much of the fruit was very small. Nevertheless, the crop was still heavy enough to bend all the branches horizontal and it was a miracle none broke, especially with the strong winds we've had constantly for the last month. If a similar crop develops next year, I think thinning by 50 % would probably be advisable.
