Here in FL they have something called Black Kow; I never saw that up north. If you must purchase manure, buy a bag from the nursery. Don't keep changing the soil. Dig out the top few inches, put down the manure then mulch and water. I'm a long time gardener but very new to bananas so I'm giving general advice; others here can give you more specialized suggestions. But it appears to me that your plant is competing with the lawn for nutrients/water so get rid of some grass and let your banana have a space of her own. I believe that's a banana but don't know what variety. Where did you get it? If you purchased it, there should have been a tag. If it was a gift, perhaps your donor knows what they have.
