Yellowing and browning
I have one or two banana plants that the leaves are turning yellow and brown. I have two images, but I can't figure out to get the images from my gallery to this post.
One is a Kru and one is Gran Nain. I don't think it is disease or bugs, but why would these suffer from lack of water or fertilizer, and none of my other many plants not show the same symptoms? I have been fertilizing with chicken manure for the most part, and also with 8-6-8, which is about the best fert I can get in my area. I water once a day for 45 minutes - 7:30 to 8:15 am, on an automated system. Here in the Bahamas of course we have sun almost all year long, and it is hot as two hells and the humidity is about 75% at this time of year. Any suggestions would be very much appreciated. |

Re: Yellowing and browning
I'd check the soil on those two to make sure they are plugged up and the soil is getting what its suppose to. You might take a look the roots while your at it if the aren't to far down... Give your self an answer or some peace of mind. :^)

Abnshrek, when you say plugged up, do you mean to make sure the soil isn't draining too quickly? |
Re: Yellowing and browning
it looks like overwatering. is your soil clay there? if so it's too much water even with it being hot and humid

Would you say that a good soaking every two days would be good for my area? |
Re: Yellowing and browning
Is your chicken manure composted?
Chicken Manure Compost – Chicken Manure For Vegetable Garden Fertilization It says: (quote) But, the high nitrogen in the chicken manure is dangerous to plants if the manure has not been properly composted. Raw chicken manure fertilizer can burn and even kill plants if used. Composting chicken manure mellows the nitrogen and makes the manure suitable for the garden.(unquote) |

OK, it was just a thought. I'm glad the roots look good, and I hope they recover quickly!

Re: Yellowing and browning
It could be over- or under- watering. Could also be fertilizer burn from over-application.

I'm gonna reduce the watering for a while and see what happens. All of the reading I had ever done suggested that bananas like a lot of water, so I was watering every day for 45 minutes, in the morning. All of my other trees seem to be doing fine, so I'm skeptical about the fertilizer, but of course I won't rule it out. |
Re: Yellowing and browning
Try a little Epsom salts to see if that greens it up. Use 1 tbsp. per gallon. Good luck.

I'd water the affected plants by hand for a few weeks, till they recover. Beyond that point, you could attempt to tailor your automated system to your plants' needs. Right now, though, I'd water by hand for a while just to make them happy. |
Re: Yellowing and browning
It looks like it's not getting what it needs. Try hoeing the soil and then mix composted chicken manure in it. And then water it properly. Or the virus can also do this to leaves.
