Mine are struggling because my damn Roselines eat this stuff. I've lost the majority of it but there are a few lone clusters that are starting to show signs of spreading. I just hope they pull through lol.How's this plant doing for you speedie? it's not growing very well for me after planting. I don't see any new runners, i thought this was supposed to be a fast one.
You need to plant them by stems or in small clumps. You can not plant a "mat". It simply won't work as you've already experienced.
