Rosette plants (swords, vals, sags etc...) you want the crown above the substrate, when I plant rosette type plants, first I trim the roots to about 1in and then I will push them down into the substrate and then give a slight upward pull to get the crown just above the substrate and the roots pointing down.
Rhizome you don't want to bury them and the roots will find their own way into the substrate or what ever they are tied to.
Bulbs can be partially pushed into the substrate but not buried
This is very excellent advice; I couldn't say it better. I use exactly the same method for swords.
Ksaster2, the only plants I see that may need attention are the two spotted leaf swords, for both I would gently take hold of a few leaves and just pull slowly upward until you see the white crown where the leaves sprout from. If the crown gets buried, the plant can rot. Otherwise, good looking job.
