I continued with the job of bubble wrapping some more containers. I did run out - so note to self - go shopping for bubble wrap later in the week.
I finally managed to get the over sized terracotta pot which is currently home to my Coral Bark Japanese Maple - Acer Palmatum 'Eddisbury' moved.
It suffered very badly from poor drainage earlier in the year - now recovering well. It will be re-homed elsewhere in the garden next spring.
