Not a stupid idea. I've been studying ROD for years and I keep learning. Knowing what I know today, this is how I'd tackle it, with the following goals in mind:
*Speed to growth
*Cost savings
*Likelihood of success
*Speed of installation
1. Skip over the cutting and go harvest wild plants right when the frost comes out. You can pull 1-3 dozen stems per minute depending on how rich of a honey hole you find. This will save you hundreds, if not thousands in purchasing costs. So I wouldn't rule out driving up to 3 hours one way to find some.
2. Plant 10-30 seedlings per hole right away, skip the potting phase, and then cage/mulch them. If you site match them well enough, I don't think you need to mat them, but you certainly could. I also like to bring in outside topsoil, just to be certain I get the roots covered, and I'm not trying to make soil out of 8" slabs of sod.
3. If you have enough surplus brush laying around, you can always plant bigger groupings and build a hell of a brush wall around them. It doesn't need to last forever, just long enough for them to get above browse height. I think a few dead spruce or cedar trees would make about the best barrier I could think of. Hardwood tops with softwood brush thrown over the top would be a close second. You could also put in a row or square and use Tenax fencing to keep the deer out. Now you're talking about buying fence posts, and that can get awful expensive quickly.
