A fine pear

Just a garden shot today; the blossom on my pear tree.  I have three fruit trees trained against a wall.  The apple and pear are doing fine and in full blossom but the plum tree seems singularly reluctant to produce anything but leaves.  Its days may be numbered; there's another place in the garden I could put it but it wouldn't get so much light, but it would free up space for the apple and pear to spread more.  I'll need to research 'best time to move a plum tree'.
