Citrus trees survived the winter

My 4 new citrus trees have all survived the winter! The lemon and both oranges looked a bit unhappy and a few small bits died, but they are now growing madly and are a lovely dark green again. The Tahitian lime I thought had died - it lost every single leaf! However, I left it there and it has now grown lots of new, healthy leaves.

On the other had, the citrus that have been in pots for 2-3 years on the north-facing verandah, still look quite unhappy. The cumquat is making a valiant effort but the last remaining orange was looking very unhappy, so I have movied it into my new greenhouse. It wasn't a good time to move it, as it was flowering, but I thought it might give it its best chance.
