Basjoo leaves browning, spine of leaves going black?
 
Hi all, I'm pretty new to Banana plants!

I was hoping that with your knowledge you could pinpoint what's going on with my Musa Basjoo.

It has been kept inside over winter and had slowly grown new leaves, I planted it outside approx 3 weeks ago.
The browning started on the old leaves first which I'm guessing was down to shock? The top leaf only developed last week and has already gone brown/black (as picture) so I was wondering if there is more going on...

Planted in a mix of average soil with compost, horticultural grit, and a little dried farm manure. I've fed it with liquid 24-8-16 a week after planting. The spot is a little windy with full sun.

I live in a uk H3 (usa 6b) zone and it has been unusually warm this time of the year (20c, 71f). It has only been cold at night the last two days with a min of 5c, 41f.



I had trouble with the image gallery so i used Imgur, hope thats ok!

I have looked for spider mites but the leaves are clear of anything.

The brown edges of the leaves appear to be from over watering. The base of the leaf in the 1 st photo appears to have been eaten by a bug and enlarging the photo I think there are several bug bite marks. This may be the cause of the black in the mid-rib. ... when you shake the plant do you see any flying bugs? ... Anyway spraying to control sucking bugs will not hurt the plant. Also, look down in the top of the pstem for any worms/larvae.


The leaves of the plant have folded down. High heat (100 + deg F), lack of water or root damage (lack of water & nutrients) are the cause of this. Root damage can be from insects & nematodes. So check the soil.
