scarifying redbuds

I might try my hand at growing some Redbuds (Cercis) from seed.

I've read that the hard seed coats must be scarified, usually w/Sulfuric acid, boiling water, or filing before stratifying.

Can anyone who has successfully done so tell me the best or most effective method of scarifying/stratifying the seeds?

Depends on the type of seeds and especially on the size of the seeds. When they are large enough, I prefer a file or a sharp knife. In the case of some Gymnocladus seeds, I actually used a bench grinder (-:

p.s. The bench grinder worked very efficiently. The only real negative was the smell of burning seed shells as the stone ate through.

RE: scarifying redbuds

Dumb question...which end of the seed should you file? I assume the non-embryo end, or the side. Is the slightly "pointy" end the embryo end?

You just have to "expose" a small part of the inside so it can imbibe, is that correct?

Yes,to both questions.

RE: scarifying redbuds

Half century ago I got this notion that I would pick up a cheap lapidary tumbler a yard sale and experiment with that to scarify seed.

Don't recall why but I never even got my experiment started.
