I have a bannana peel laying by danahue that isn't buried. If this works I'd be curious guess I will bury some tomorrow around various roses.. The Rose Clear has come out and the spraying commenced on the little buggers. I tried Neem Oil but it just does nothing but burn the leaves of my Austins. So we are now back to rose clear. I use another brand called growing success that has been bought out by Westland that is mostly organic. Then I spray soapy water if I'm in the mood but being they aren't fungused and blackspotted up yet the rose clear is the better choice. -- Nothing like your expensive roses smelling like lemon dish soap . lol

I just got my first plant and i was surprised at how bit it is. I ordered it from amazon and most people said theirs came in at about six inches. Mine is about 12 inches with 9 leaves and two small sprouts on the bottom. It looked very healthy so i transplanted it to a new pot as the roots were growing through the pot. I will continue to monitor it. T Here is a link that might be useful: my photos

It's called guttation, and it's quite common among large leaved tropicals kept indoors over the winter. The crown of thorns has anything to do with it.

Here's a link on how to protect your bananas in the winter: https://www.crfg.org/pubs/ff/banana.html I think it would be tough to keep it outdoor with your Winter temperature there. Some people overwinter their bananas by cutting them down and then storing the rhizome indoors. When the warm weather returns, they bring them out to plant again. Here's a video link to show how it's done. https://www.youtube.com/watch?v=ZVga_4pX0Oc I know it must be disappointing to hear this .... I wish too they could stay out without being cut down. If you grow them in a greenhouse, that might be possible. Do you have a pool screen enclosure? If you do, I wonder if that could offer some protection to your bananas and if you could also warm the area up?
