Banana trunk problem & questions
I have 3 questions. Below is a picture of what I have been told is musa velutina. On one plant, the leaves dry as they go bad, but on the other they appear somewhat soft & turn black. I saw some bugs near the base of the second picture, but I superficially treated it & do not see any more. I am afraid to change the soil until the summer heat dies down, but could a bug in the roots cause this?
Problem velutina overall (leaves are burned a bit)
Another question is how to grow a strong banana. I want to grow bananas like the veluntina, with a strong base. Is this a matter of plant maturity, plant variety, lopping off the top, growing it in the ground or what. A commercial grower grew this one, so I suspect he had some fertilization trick.
My last question is how to trim a banana. I am not fond of burned leaves or sloppy trimming on plants. Does anyone know of a way to trim banana plants - like someone who was putting them on display would do? Is there a way to make a clean cut on the old leaves so it looks more tidy?
Thanks for any help, & sorry for the long post.
