Winter mulch: Good idea or bad idea?
My banana plants have become victims of the cold snap that has washed over the western US. I want to do everything possible to keep the pseudostems alive this winter (lowest we'll get here is around 25), so I spread some wood chips and fallen leaves around the base of the pseudostems and pups to about 1.5 feet high. The pstems have dulled in color a bit, but I'm pretty sure the damage is only superficial because they are still firm and moist. Will the mulch get too hot, or promote rot?

Hi Andreas,
Definite figures do not appear to be available, but all banana leaves freeze up. if exposed to the upper twenties. Exactly where that point of freezing lies, depends very much on duration and wind exposure. Hardiness appears to refer to the survival of the corm only. The tops, leaves and PS are as far as I can tell exactly the same for all varieties. I have experimented some on the musa basjoo here: http://www.bananas.org/f10/experimen...ana-19329.html. What exactly makes the more highly rated varieties less frost hardy, would be subject to experimentation, which is not available to me. Is it subject to rot at low, but above freezing temperatures? Would relatively dry, well draining soil during the frigid period help the corm survive? I cannot experiment in borderline temps here, because it gets too cold. I am fairly sure, that any frost, which is sufficient to kill the leaves will either delay or nullify the fruiting process, more so, if it damages the PS. Maybe this is, where the difference between some of the cultivars comes in? Meanwhile to come to your question: I do not see, where mulching could hurt, unless your region is subject to long and cool soggy periods. If so, just spread a plastic "apron" over the mulch.. Best, Olaf |

I doubt, that your leaves will rot, if they remain exposed as your weather allows. The
frozen parts of the leaves will more likely dry up more, as they have already done at the edges. If there follows a period of no frost, you will probably notice signs of recovery and emergence of new leaves. Just monitor the weather forecasts and cover them up, when frost is threatening and they will be alright. :) Once they have recovered, in February, you may want to slice all the dead parts of the leaves off. |

Not much composting going on in winter

Re: Winter mulch: Good idea or bad idea?
Does that mean that I could get root rot?

I have always mulched around mine after wrapping them never had any problems. If you were in a area that has sitting water after hard rains then of course don't mulch during cold whether otherwise go for it.
