This park is truly a Sabal pametto paradise. I know, there are plenty of parks in Florida with wild Sabal palmetto forests; however, there is something about the way nature presents itself here that keeps me coming back. These pictures were taken on Christmas Day of 2020. I have also seen Roystonea regia and Serenoa repens growing in the park as well.
So, I have always understood that Sabal species need to have a portion of their heel showing above the ground line when young. Other palm growers have told me this, and the Palmpedia entry for Sabal palmetto even says the same thing; namely, that “…this is a tillering palm, it exhibits saxophone style root growth (it has a heel), keep top third of heel above soil elevation” (http://www.palmpedia.net/wiki/Sabal_palmetto). I have always followed that advise for the Sabal species I have grown (S. palmetto, S. mexicana, S. minor, S. causiarum, and S. uresana), and I have kept a good portion on the heel above ground level (both planted in pots, and planted in the ground). I have had success in most cases; however, I have come to question the necessity of that “conventional wisdom” recently after a trip to visit my father in Cape Coral, Florida last Christmas. We went to J.N. Ding Darling National Wildlife Refuge on Sanibel Island for a hike and, while there, I paid close attention to the young Sabal palmetto palms that were growing all over the place. I must have inspected over 60 juveniles, ranging from new seedlings, to palm frond heights of 3 to 4 feet. I could not find one young Sabal palmetto that was showing a heel. Most of the juveniles without trunks had their petioles growing straight out of the ground (or sand as the case may be). Since they are growing wild in habitat, I figure this is how they normally grow. Below are a few pictures I snapped there depicting this. Do any of you have thoughts on the necessity of showing heels on your Sabal species?
Today I see a yellowing leave stem, it’s the 7th leave and some rust like spots. I don’t like it and am concerned. What is it and what should I do to stop it?
Since they like water not sure if she got too much. Hope somebody know Leo an assist?!
