Danno, I'm no expert, just a container gardener learning as I go.
I'm glad you got Quinalts, that's kind of a funny coincidence that they were all the nursery had.
I like them because they are sweeter than any strawberry I have ever tasted. Like they've been sugared. I eat them right off the
plant and they don't nake me pucker. No trace of sourness AT ALL.
I don't know about your questions, but one of these nice people will, I'll bet !
As far as the runners being planted, you don't have to unless you want to.
As I understand it, a Quinalt runner will fruit, but if you want a good sized
plant you could
plant the runner in soil, and of course not cut it from the mom until it has rooted.
