Just a quick question,  I've been growing Sarrs for 15 years now, and 
have always repotted them in early spring.  I'm not sure where I heard 
this, but somewhere I either heard or read that mid winter is better.  Is 
this true?  The reason I ask is that, is that when I transplant them in 
the spring, I find it seems to set them back quite abit!  Will winter 
transplants be less stressful?  Any comments.
Thanks in Advance
Carl
