I was preparing to plant some new banana plants I got a week ago in the ground today and noticed that on two out of the three plants have started getting black spots on their stems and one leaf per plant. Is this normal? I got the two from the same nursery, inspected the roots when they arrived (no rot seen), and had very minor discoloration at the time on the stems but thought it was due to shipping.

[RESOLVED] Never found out what the black spots were but they continued to grow in size and were present throughout the entire pstem. I ended up throwing them away so as to not have whatever they were afflicted with infect my healthy plants.

Just curious but did you get them from Green's nursery in Apopka. I got a bunch of plants and noticed that black kept eating to the core. Threw them all away

I ordered them from Florida Hill Nursery since Lucas Nursery in Oviedo didn't have them at the time which is where I normally get my plants from. They were supposedly from disease free tissue culture. :(

I believe it to be bacterial. I think you have what mine did. I could not cure it and I even isolated a few miles away to see them grow and it was persistent. My neighbors finally would succumb to it. I think it is bad. I hope you get a better reply than me because I am also curious. My collection is so awesome I can't risk these companies messing thatup with contamination.

I wish I knew what it was as well. The third plant I have is looking very healthy and I'd hate to see it get infected too. I went ahead and trashed the two (they were cheap) and will replace them from a different source.

Try spraying the plants with a fungicide . I mix and use copper sulfate but there are other off-the-shelf products available. also, mist the plants weekly with a folar spray of weak fertilizer (miracle gro)to help straighten the plant. You might be able to save the plants. The infection looks to be in early stages.

I really think after this post that these nurseries have shared some sort of disease. I posted mine on here when I got them and I'll see if I can find it and bump it.

Here's some pictures of one of the plants. The other is in pretty much the same shape.

Sorry about the links, I deleted them after I threw out the plants. The black spots had grown completely throughout the pstem, including the center, and I didn't want to risk them contaminating the unaffected plants. It's been a few weeks and it seems the healthy plants never got whatever was affecting the ones with black spots.
