As in all nutrients, there are limits. For a banana plant past the juvenile stage, it's not going to utilize much more than
net 1.5 lbs potash per year -- and somewhere above that level (perhaps double) it will suffer from potassium phytotoxicity and die. In terms of K2SO4 (potassium sulfate):
net 1.5 lbs/yr potash is gross 3 lbs/yr.
