One mature Banana plant needs 1 lb of nitrogen and 1.5 lb potassium total for the year. This to be applied during the growing season. The mature plant needs very little to no phosphorus (P).

Using 18-10-5:

Nitrogen = 1 lb /.18 = 5.56 lbs for the growing season. Divide this by the number of applications.

Potassium: The same 5.56 lbs of 18-10-5 will supply (5.56 X .05) .225 lbs of potassium. You need additional potassium from the 0-0-60 (potassium sulphate ?). !.5 lbs - ,225 lbs = 1.28 lbs potassium needed; 1.28 lbs / .60 = 2.13 lbs of the 0-0-60 total for the growing season.

So the total 18-10-5 for the growing season is 5.6 lbs; and 2.2 lbs of 0-0-60 (** rounding up this small amount will not hurt)
