I know this ain't boo, but I've done boo like this.
If you ain't wanting to use the bushy top, jus plant it. Make ya a stake driver out of PVC and push it into the bottom of the lake. This works really well when ya cut the top out so ya got something to push on. It also works good when ya got a bunch of butt ends left over. Jus drive em like stakes. Now get to work.
