I don't know what kind of banana tree you have but it seems to me that the growth rate is not very good. If the mama was 7' at flowering I think its reasonable the plant should have achieved 4-5' of pstem growth in nine months under average conditions in Jacksonville, Florida. Since we had a ton of rain this year in Florida its not for lack of water so I'm thinking its due to lack of sunlight and lack of organic matter in the soil. Leaf color looks pretty good so fertilizer/nutrients are probably adequate although they may not be optimal and something to look into but not the main issue.

I see what looks like a lot of bird droppings on the leaves which indicates the plant is under some type of canopy where the birds are hanging out which implies lack of sunlight. Looks kind of shady in the yard too. Visible soil is white which indicates lack of organic matter and lack of mulch (grass clippings, oak leaves, etc.) which helps to retain soil moisture.

I suggest looking in your yard to find a spot that gets the most direct sun the most of hours of the day. Protection from the north wind would be optimal but not the most important. Dig a hole about 3'x'3'x3' (removing any pine roots and such) in the sunniest spot and backfill with 1/3 to 1/2 of your normal soil plus some type of organic matter maybe oak leaves/grass clippings if you have them or cow manure compost from lowes (three 40lb bags) if you don't have anything suitable. Let that spot sit until March (if you used oak leaves and grass clippings so they break down) and then transfer your plant to the prepared spot in March. I recommend transferring after winter although its pretty small you might dig it up and put in a pot and keep indoors for the winter so you would have a better starting point in the Spring.

The above suggestions are summarized from what I received from a nursery in Crawfordville, Florida in Wakulla County for my banana trees. You can check out the photos in my gallery for the results.

Good luck!
