Down at a local nursery today, I was told that mature roebeleniis have been dying of ganoderma - a number of instances of this around town.  Now I'm quite worried, as one of my favorite palms is an older roeb, front and center in my yard.  I love looking out the window at that palm. This is very bad news, if the problem is widespread.  Roebs are one of our most common palms, but the grace they give to a garden should not be underrated. St. Pete just wouldn't look like St. Pete without them
