Your welcome twitcher. The gist of LariAnn's article was fertilizing in synch with the natural nutrient availability. A high nitrogen fertilizer in the Spring, a balanced mix in the summer and the high P mix in the fall. Spring 20-6-12, summer 14-14-14, fall 14-26-6. Hopefully LariAnn is "listening" and will comment. I don't think I've ever over-fertilized a C. esculenta when they're actively growing and I exceed the recommended dosage regularly.
As to moisture needs the C. esculenta varieties I have love water. Those in pots are all set into a tray or basin full of water (I picked up several oil change trays at a discount store and use these). Those in the ground are in soil amended with materials that retain water and are covered with 2 to 3 inches of compost. Elepaio should do well in a boggy situation.
