I found a centipede fertilizer 12-0-12 and a potash fertilizer 0-0-36(not sure of this number) that I can mix to get a good ratio for my bananas but that would have zero phosphate. Do I need at least some phosphate?

Thanks

I think the ratio is 2-1-3 if I remember right..

Yes.

If you mix equal weights of those, the result will be 6-0-24.

Your phosphate needs are largely dependent on the amount of phosphorus that is currently in your soil and your pH. My soils test high for water soluble phosphorus so I don't fertilize with P.

Thanks Richard for the advice.

I have some 10-10-10 I can mix in by weight to get somewhere close to the 3-1-6 ratio. Almost everyone post about the N and the K and the UF ratio is so small so I was beginning to wonder if you needed any phosphate.

Have your soil tested. You can probably get it done at your local extension office for $12-$15.

Six pounds of 12-0-12 plus one pound of 0-0-36 would yield seven pounds of 10 2/7 - 0 - 15 3/7.

I do need to have the soil tested. That would be the smart thing to do.

Richard thanks for the calculation.
