My indoor banana produced 6 healthy pups which I successfully repotted a few months ago in spring. All pups have grown to become healthy banana plants, one in particular had a very thick stem and large leaves and quickly grew to be the biggest. Here she is in her healthier days, only 10 days ago (second from right in the biggest brown pot):
However, over the European heatwave 3 days ago she suffered greatly:
And has not responded overnight to extra water:
Any ideas what has happened to her? She is seemingly the only one of my 6 plants to be affected in this way. If there is any hope to save her I would love to hear your suggestions. Many thanks!
