Wow, lots of great intel in there, thanks for taking time!
I did get my stuff from Nourse, but I got Purple Passion and (...wait for it) Jersey Knight. Well, my stuff was AT LEAST 25% female, and I think probably more. I've been taking them out at the end of the season, and replacing with new crowns. Still is seems like no matter what I do I still find some sporting the red berries before it's over! And yes, they are like weeds!
On the planting depth, I think mine are plenty deep - question is: If I keep adding bags of Humus to cover like 2" at end of season (year after year) is that a problem? My 'Gus bed kinda looks like a long raised bed mound sans the wood sides, but they seem to find their way up every year.
Your comment on the stress makes me wonder if I could have damaged some neighboring roots when yanking out some female crowns last year.
