Since Osmocote Plus has been discontinued, there has been quite a few discussions on suitable replacements for DIY root tabs. I've seen numerous recommendations for Dynamite Plant Food "red bottle." It has slow release granules NPK + micros. Might be worth taking a look at if O+ was to your liking and the O+ well dries up.
