I just looked at the satellite map of Micanopy, FL, and saw that except for patches of meadows, it's pretty much wooded. That would suggest that the soil and climate are conducive to growing plants. Assuming that the soil in your meadow has not been treated with weed killers in the past, I would suspect that the soil has something to do with it. I did notice though, by looking at the photos in your gallery, that there are weeds only near and under the mulch around the bananas. Or is just that area where you took those pictures that is like that?

Again, I would suggest that you take several of those pups and plant them elsewhere on your property, where the soil may be different than at the spot they're in now. Better yet, plant a couple of pups in separate containers, in the 20 to 30 gallon range, using potting soil from the garden center (Lowe's, Home Depot, etc.). Put one near where they were taken from and the other neat a partially shaded area but warm area and see how each responds. By putting one near the original spot, and another in a slightly different environment, depending on how they respond, you will have at least eliminated either the soil or the environment, or both, as the cause.

Make sure they are adequately watered, and fertilized regularly.
