Hello,
Since i got my bananas to the basement for overwintering,i am seeing continuous yellowing of the margins followed by die back of the leaf till eventually it reaches the midrib and the whole leaf dies and hangs but the leaf sheath seems to not die back too much. What i have noticed is that as the leaf tissue yellows and dies,it gets black and white spots develop on the black tissue,like the reproductive stage of a fungus.
Here are pictures of my bananas,others more and others less affected:
This one is a special case. It had good and normal leafs and as soon as i got it in my basement,it started having the marginal yellowing seen in my other bananas. It progressed fast with it not producing any new leafs but starting to bulge at the base as the new leafs couldnt emerge through the pseudostem. The yellowing progressed fast,reach the midrib and all leafs died. A deformed leaf tried to emerge from the dead tissues but it started to blacken at the margins too and eventually died while at the same time,the 2 new leafs you see started emerging fast! If you look closely,the dead,blackened leafs all have a white dust like the reproductive stage of a fungus which worries me in case it reinfects it. So far,this one seem to now be on its way to recovery.
Although the above banana managed to recover,i would certainly not want my other bananas die to the ground to start recovering again,if they recover. What cases this yellowing and then blackening and what should i do to help by other bananas win the battle?
Thank you very much in advance!
