Hi, have had this Ice Cream for two years now. For the third time now it looks like the fruit does not fill out and ends up just turning brown on the tree.
Is this a nutrient deficiency? If so, what is the best fertilizer for bananas?
Below are links to two images. Hope you can tell something from the pics.
Thanks,
Bianca

Possibly Anthracnose? Google Anthracnose on banana plant, and see if it looks similar in the pics of the fruit.

To me this looks a bit like crown rot, which is a fungal disease, although it could be a few others things in conjunction with each other. Whatever is happening it is stemming from a nutrient deficiency. When a plant is developing a rack of bananas it is consuming a tremendous amount of nutrients. If it is lacking it will put everything it has in to the fruit and become dusceptible to a multitude of diseases and pests, which is what I think is happening. It's important to fertilize a small-medium amount every month, and fertilize heavily once a flower pops out, especially with nitrogen, potassium, boron, calcium, manganese, sulfer. You really can't over fertilize these guys!

If the stalk has fruited, then the lifetime of the stalk is over. New ones will sprout from the base -- if they havent already.

Yes, I believe you can. 5 to 10 lbs of potassium sulfate to a single plant will likely induce potassium toxicity -- which has the symptoms of manganese deficiency. There's no reversing it.
