Most of what I read here suggests a high K (potassium) ferilizer, like 15-5-30, or 20-5-30 for bananas. It is very difficult to find anything like this in places like HD, or Lowes. Everything they have is "general purpose", or lawn food (high N - nitrogen) I remember, over the years having been in some farm stores, in New Jersey and Pennsylvania, of a company called Agway. The way I remember it, these places would mix up the fertilizer, in any formula you wanted. So, I Googled the name, and found a location about 15 miles from here. However, when I got there, I found it was not a company store, but a regular garden center that happened to sell some Agway products. They did no mixing, and the best I could do was to get some 0-0-60, and I'll have to do a little mixing myself. (I probably could have gotten it right here, at a local garden center) Then I read something about using a "bloom booster", and that the 15-5-30 is a good bloom booster. The only "bloom booster" I've seen are high P (phosphorus), something like 0-50-0. This is pretty much the opposite of what is recommended above, and, certainly, 15-5-30 wold not qualify as a bloom booster.
Sounds like people are guessing. Can someone, who's not guessing, clear up the confusion?
