I have a mature pear tree in my garden, at least twenty years old. Whilst it looks healthy enough, it produces hardly any blossom, some years none at all. It did produce a few fruits a few years ago, but nothing since. The fruits it did produce were quite small but ripened OK and tasted good but I've no idea what type it is. So.. is there a magical formula to get it to produce next year? I prune it back as per apple trees but in the late Autumn, could that be the problem? Thanks for reading, any advice welcome
