The Edgeworthia which I planted last autumn is showing new growth at the soil line. Should I prune this or leave it alone? Thank you!
If you want it to maintain its tree like shape, then you will want to prune these off. Otherwise, they will bush out, as they would in nature.

Best time to plant a "paperbush" bush plant from seed,
You will want to do this after all threat of frost has passed. It is best to start these indoors under bright lighting to give it a better chance of survival.
Since you are on the edge of this shrub's hardiness zone, it may need extra protection in the winter.

A friend has a large stand of Edgeworthia and she decided to dig some out on June 3rd 2024. Not the best time of year to transplant but I took some of them. My question is, would it be better to leave them in the pots in shade for the summer or would it be better to plant them in the ground and baby them all summer
I think that it would be best to baby it in container until it is healthy enough to plant. Early fall would be fine if it recovers in time. Here is some information on its care:
