Greyduster, Monty was planting cordon apples, so you don't need to watch him if you recorded GW. I think most fruit trees do well on alternate years. Bob Flowerdew would be able to answer your query (I like him on Radio 4's GQT).
Liaise, my Tiny Monster kept its leaves too, but is still quite a small plant. I haven't seen Heidi before, on Google it looks the same colour as my favourite long flowering season geranium, Rozanne. I have yet to beat it. One of mine clambers up through a neighbouring bush, I love it!
