Not sure about what you mean. If you mean how to make dried, mounted plants--herbarium specimens--last longer, mount them on acid-free paper using pH-neutral glue or mounting tape. Keep them in a cool, dry place like a cabinet sealed against insects. Don't handle them much, keep them flat in folders, but inspect them annually.
