My landscaper planted several kinnininnicks in my front yard rock garden several years ago. Every year, they would suffer from severe die back after winter and now they look half dead. I am just wondering how they do here in Calgary? Or is it just the way that they were not planted properly in my front yard? It seems like the landscaper put on a lot of mulch in the front yard and THEN his summer job students planted things in the yard.... so I am guessing that most things may have roots in the mulch and not much in the soil....but that's my theory.... what do you think?
