Hi all. Something is up with my tall namwa. The new leaves are not growing properly. Any ideas?

Im no expert but look up bunchy top

Overfertilization can cause really fast growth which results in deformed new leaves. If that's not it this website says calcium deficiency can cause deformed leaves: https://tropicalselfsufficiency.com/...ies-in-hawaii/

To my eyes, what I have going on looks more like a calcium deficiency vs. bunchy top (at least, I hope!)

I had something like that happen to one of mine last summer. Here is the thread:

Worrisome leaves- BBTV and BSV?

dont worry about it, dont do anything to it let it grow.

Here are some up close photos of the leaf and what the new one looks like. I haven’t been fertilizing so hoping it’s a nutrient deficiency. Does it look like bunch too to anyone?

looks like over fertilization. whats your neighbor doing on the other side of the fence?

i have one doing similar to that, the cow manure and compost i am getting has been generally just a bit hot.

That's a good question. They just have ornamental landscaping over there, so I doubt they are doing too much fertilization. But I don't know. I pile wood chips pretty high up the bananas and my food scraps and coffee grounds. I didn't think it would be so much as to cause a problem though, as I know bananas are heavy feeders.

TheVeggieProfessor

Just wanted to give this a quick bump to see if there are any other opinions on the new close up photo. To me, there appears to be a j-hook pattern, but it isn't clear. The new leaf is coming out smaller and more damaged looking. Many of my other bananas are starting to produce leafs that are yellow and smaller than typical. If it appears to be BBTV, I'll have to remove a reasonable number of plants. I'm grateful for any further opinions on the look of the leaf. Does anyone see a morse code type pattern?

There could be several reasons why your having problems. You might have a deficiency of some type. Can you tell us your setup; what type soil, fertilizers, frequency of watering?

TheVeggieProfessor

Thanks for the response. I'm in south east florida (west Browrad county). Soil has a ton of limestone. I'd call my soil sandy, with a darker layer of top soil on top. I mulch my bananas very deep with arborist chips and bury food scraps and coffee grounds under the wood chips as they are available. Deficiencies could indeed be very likely. At first I was fertiilzing with sustane 8-2-4, but I didn't keep up with that. I've just been mulching and adding food scraps and coffee grounds and described. Everything was going along fine until recently when that odd leaf appeared. Now I am noticing the same thing beginning to happen on many of my bananas. New leaves are yellow and getting smaller and smaller. Pups are starting to look very odd.

EDIT: Since I thought these could be symptoms of deficiences, I just fertilized all of my bananas with sustain 8-2-4 2 days ago.

how much coffee grounds are you talking about

curious, think i read once that coffee grounds need to be composted before being used. but you cant always believe what you read.

Interesting. I figured they'd appreciate the nitrogen. A pretty good amount. I usually drink 2 cups a day and I've been dumping the grounds on my 11 banana plants for the past few months. So they've gotten a fair amount.

I do about the same with coffee grounds and vegi/fruit scraps, never had a problem yet.

beam2050

Depends on the banana. Some are more sensitive rhan others.

I have put coffee grounds around mine, but not to that extent.

Florida is known for deficient soil, so I bet its a microdeficiency. Or the soil has become too acidic, which would render certain minerals unusable.

TheVeggieProfessor

This is what I'm going with for now. Probably not too acidic; my soil is loaded with limestone. I'm assuming my soil is too alkaline if anything. However, I agree that a nutrient deficiency is likely. I just fertilized my bananas with sustain 8-2-4 the other day, but additional minerals could be useful. Any ideas? I was thinking of adding a calcium supplement.

Backyard Banana Joe fixed his by doing this.
Read the short thread for takeaways.
