Laurie - Fertilizer is promoted as the remedy for practically every plant ailment, yet it is an exceedingly rare plant problem that is solved with plant food. But I know how seductive it is to attempt to fix a plant problem by simply adding fertilizer rather than getting back to the root (pun intended!) cause.
Sue - To add to your point, I have had 30 years of professional experience and still lose plants. Case in point, I have been carefully rooting some Jade leaves from a Jade originally owned by the artist Georgia O'Keefe for more then 6 months. I just lost them this week. So it goes - another learning experience.
