If you are growing fruiting bananas and want more fruit production, you'll need a potash supplement so that in total you have 1.5 as much potash as nitrogen. It seems that Sul-Po-Mag at 0-0-22 would be a perfect match for your 20-10-10. Use the same
weight of each. If they are in the ground, you'll want to apply 5 pounds of 20-10-10 plus 5 pounds of 0-0-22 over a period of 1 year. I would do it monthly because too much at once will burn the plant. For potted plants, I would try 1/4 of that dose. You'll find Sul-Po-Mag sold cheaply at farm supply stores, about $20 for a 50 pound bag. This is not a synthetic chemical but rather a mineral mined out of the ground.
