Best and cheapest way to send scionwood

You could also seal ends to help maintain moisture. With paint, wax or tape.

saved some styrofoam padding(those with cavities) from the boxes of flat panel tv’s which proved quite handy.

being thin enough to fit in flat boxes, yet thick enough to resist crushing, and i hope…

I received some wood nicely sealed at each end with wax. They looked a bit dried out to me and I had 100% failure with the grafts. Sealing the ends is useful but storing with high humidity is also helpful.

Yeah storing right is more useful. It may even hurt them by blocking moisture uptake.
