for potassium if you have a fire place use the ashes collect them and use them around your plants only once a year because alkalinity can build up and remain long after the potassium has diluted. dont use this stuff around acid loving plants like azealias because it contains lots of lime.it contains phoshorus too
you can use the stalks of the bananas itself once the season is done cut up some of the stalks and leaves. its easier done while the stuff is still green.try to turn a lot of the garden greenage into compost.use any greenage from table scraps..avoid using meat products unless you want dogs and other carnivores in your yard.. remember the urine formula for every part urine use 8-10 parts water try puring a little urine over your compost to speed ut the decomposition...good luck going green.
