I only grow organically. You can check my photo gallery for pictures of the various bananas I grow.
When planting I mix in steer or chicken manure, green sand, sul po mag, worm castings, EB Stone organic plant food, and lots of compost. I keep my beds amended with steer manure, compost, sul po mag, and organic plant food. I have never had any issues with bad insects or disease. For potted plants I feed them a steer manure/compost tea with organic plant food mixed in.
Nothing on my property receives any chemical foods or pesticides, not even the grass! I have two dogs and don't want them getting sick from any nasty chemicals or weed killers.
