Inkcube, that's very interesting. Your rainfall on an 8 ft x 8 ft area works out to be 75 to 150 gallons per week. You are using a little over 1.5 lb N (nitrogen) and 2 lb K (potassium) per plant per year -- unless as you say, it is a very wet year.

You did not mention phosphorus. Is it to be avoided on bananas?

In semi-arid San Diego, it rains about 6-8 inches per year. I water the myriad fruits in my home orchard about 30 gallons per week, including rainfall if any. Each tree receives up to 1 lb of N and K per year. Given there is adequate drainage, will this be sufficient for bananas?
