Many thanks to Richard and others for this great thread.

I have a couple of questions that I haven't found answers to:

I see various references to the annual amount of fertilizer that bananas can use. I am wondering how this relates to length of growing season? In the tropics, for example, the growing season may be all 12 months, while in Iowa my growing season is basically four months for outdoor bananas. So when I read that a banana can use up to a pound of nitrogen per year, should I assume that's a banana being fertilized year-round, and my four-month growing season would need only a third of a pound? Or would that not be correct?

Also: If water soluble fertilizer is applied once per month, should I be concerned that some of it will wash out with subsequent waterings (watering frequently during the summer) before the next fertilized watering?

Richard

Brian -- your calculation is correct. The constant feeding method is a good choice because no guesswork to the growing season length is required, nor is there an issue with washout.
