Can A. tuberosa be groun-layered?

[applestar]

I just bought a small plant about a month ago. It's growing well and one of the shoots is long enough to lay on the ground. Rather than staking it up, I decided to try ground-layering it -- stuck it down with an earth staple and covered the stapled part with sandy soil. So I'm going to try anyway, but I was wondering if anyone knew for sure how well they take to ground-layering and whether I should put some rooting hormone down.

Have you gotten any of the other asclepias to ground layer? I'd give it a try. The rooting hormone might just do the trick.

Root cuttings "look in the Propagation section"

Take part of the white stem (must be referring to undergound), see propagation.

Good section on propagation, too.
