The leaves on the one's outside have turned red and will probably fall over the next few days,
when the frost starts they will be under a fleece and then just hibernate until the spring
The ones indoors are still green, no signs of dropping, but its warmer in the conservatory by a good few degrees
Got two bags of that ericaceous compost ready for when they go in the garden, (homebase had a deal, buy two for a tenner)
