My wife bought me a small tree two years ago from a Garden Show. I am unsure of the variety, sorry!
It had a great summer on our decking, and was thriving. It wintered well, and came back glorious .... however, when we went on holiday, the neighbour watering plants for us, forgot about it. We returned to brown dead leaves. They all fell off, and we were left with three sticks ... I was gutted. Instead of throwing it away, my wife left it in a corner of the garden, and amazingly, this year some leaves have appeared on one of them ... Was hoping for advice on what to do to help it recover? Are the others really dead? Do we need to separate and re pot the surviving tree?
