Don't know about your area, but hereabouts, they're very likely to get root rot.

Here in SE PA we have European Corn Borer that lay eggs in and ingest and inhabit any sizable stem. I have found them in potatoes, raspberry canes, peppers, large weeds, etc. From their entry hole up, often dies. Look for a hole with a bit of frass as a telltale sign, then split open the stem above, and below until you find it. Kill it.
They are a worm with blackish and brownish stripes lengthwise on the body. Hope this helps, Ted
