Help! Rotting M. lasiocarpa

Posted by ornata London UK (My Page) on

Hi. My Musa lasiocarpa baby was surviving the winter pretty well in a frost-free, well-lit location. But now it has a rotten patch on one side of the pseudo-stem. There is still a patch of green on one of its only 2 leaves, but the whole of the pseudostem feels rather soft. Am I going to lose it? Should I cut down all the soft stuff to soil level? If so, will I be able to get the rhizome to sprout again? I really don't want to lose this plant. Any advice would be gratefully received - thanks.

RE: Help! Rotting M. lasiocarpa

When I have taken pups (or I should say, ATTEMPTED to take pups) off of my larger Musellas, I almost always slice part of the base of the corm off. I rarely get roots off. If there is any base left at all, I will usually go ahead and try to root the mutilated offset.

What I have found is, even after I think they have declined to the point of utter and absolute death, maybe 80% of the time, they will start regrowing and eventually right themselves, healing the damage I made when I cut them off.

The trick, I think, is to keep them on the dry side. I would try to remove any obviously rotted tissue, and perhaps dust with a fungicide like Captan, and keep hoping.

Thank you for the advice - I think I made the mistake of giving it a good watering after having kept it dry for most of the winter. I've cut it down to the base; it has a tiny pup which I hope will develop. Do you think placing it on a heat source will encourage it to sprout?

That sounds like a reasonable idea. Ours start regaining leaves (from being frosted) in about the last week of Feb/1st week of March when it gets into the mainly 70's during the days, but real new growth doesn't start til its much warmer
