When is the best time to move a camellia? I have read that it’s during winter but surely that is the time of flowering? Thanks.
It's actually okay to move plants that are flowering if you want to. Some gardeners find this the best time to transplant, because they know exactly how the flowers will look.
Also, there are all kinds of camellias, and when they flower depends on the variety and climate they're growing in.
This article has a lot of good information on transplanting camellias: http://www.aces.edu/counties/StClair/documents/NRCamelliaMoveGlover09.pdf
