For fruiting plants past the juvenile stage (base diameter over 1 inch), use no more than 12.5 pounds of 6-2-12 per year per plant. Do not apply all in one feeding, but instead divide into 4 to 8 feedings per year. If your fertilizer is water soluble, then dissolve in water before applying to the root zone. Use enough water to deliver the fertilizer to the roots but avoid runoff. If it is a granular, then apply where the irrigation water will hit it, preferably evenly in a 32-inch radius around each plant.
If your banana plants are non-fruiting ornamentals, then the 6-2-12 is a poor choice. Choose something instead with an N-P-K that is relatively High-Low-Medium such as 9-3-6, 20-10-15, or 28-8-18.
