When to transplant mature comfrey & mullein plant
I planted a comfrey cutting too close to my concrete patio and now it is quite large and should be moved to give it more space; also a mullein plant that I planted next to it and thought had died, has come back and now they are enmeshed together.
I have tried online to find out the best time to do this but to no avail. I think that usually it's Spring & Fall when plants are dormant , but I'm not sure which would be best for comfrey and mullein. I only have one plant of each so I would not like to kill them by doing this at the wrong time. I don't really have a green thumb and have problems keeping things alive so I'm a little hesitant to start digging them up unless I know what I'm doing.
Could someone please tell me?
