Banana leaves turning yellow

babalu_aye(zone 9b - St Pete FL)August 18, 2010

I've got a Dwarf Cavendish banana that over the past week or so has all of its leaves turning yellow. As you can see in the photo below, even the new leaf that's unfurling is yellow and brown. Does anybody have an idea what could be the problem? Up to this point it has been green and healthy. The pup growing next to it looks fine. I've been feeding it Black Hen, keeping it mulched and watered.

Has it ever fruited? If so, it's normal for it to die. If not, you may have been overwatering and it may have root rot. I water mine only if it doesn't rain for 3 days. I usually have dying leaves in the summer during heavy rains, though.

It has never fruited. This was a pup that came up from the ground after last January's freeze.

It is in a spot near where water runs off of the garage roof, so when it rains it gets a lot of water. But I thought that bananas love lots of water.

They love water, but nothing likes wet feet all the time. They are prone to root rot. Maybe you should move it.

"Banana plants are not flood tolerant. In general, plants may survive 24 to 48 hours of flooding caused by moving water. Stagnant water kills plants quickly. Bananas should not be planted in flood-prone areas. In areas where the water table is high and/or frequent soil saturation or very brief flooding occurs, planting on beds is recommended. Symptoms of continuously wet but not flooded soil conditions include plant stunting, leaf yellowing, and reduced yields. "

Hi. I grow banana plants outdoors in South UK.
They died back over winter but are now coming well but yellow. We did not have rain in April so I watered but the leaves were green but are now yellow. I gess I over watered. Have now stopped so will see what happens.
I did get two to fruit last year but they are not large enough to eat.
