Potassium deficiency on L. Nitida

[NickJames]

Hi All,

I am still dealing with a potassium deficiency on one of my L. Nitida. 

I regularly apply high quality palm fertilizer and I’ve already tried potassium supplements. 

Any other advice? Makes me sad! Meanwhile my hungry queens are some of my best looking palms 

[NickJames]

Just bumping this in case anyone has ideas. I don’t want to lose this palm because the space is now closed off from a machine removing it or bringing a new one in if it croaks. Am I missing something or is it definitely a K deficiency despite all my ongoing efforts?

Here’s something; does anyone think it could be lethal bronzing disease?

The fronds that are alive don't have the sickly look that Lethal Bronzing would present.  Coupling that with the fact that this species is ~95%-99% immune to Lethal Bronzing, I'd say no.  These are planted as avenue plants here and tend to show the same damage you are seeing for a year or two until they get their feet under them.  Sometimes it can take longer.  My Livistona species hate being watered, even in the sandy area.  I don't think you're at risk of losing the palm.

One thing you can check is if any of the pool water is getting splashed over that way.

I am shocked reading that Livistona spp hate being watered. Here if I leave them completely dry out before next watering, they may enter a state of big or even irreversible decline!

I think some livistona like water some dont.  My decora does very well without water while the chinensis and saribus like that water.  When I lived in the AZ desert some grew well some didnt.  Austrailis, chinensis, saribus ewere a tough grow in arizona.  Mariae, fulva, rigida, carinensis, mulleri did well in the desert.  Livistonas sp can be jungle palms and desert palms too.

[Phoenikakias]

Chinensis is  very easy in my climate and fast too. Instead fulva is a tough case. Carinensis is just a dream for me but I fear it would turn out an Hyphaena regarding its requirements. The information about the decora has surprised me, but it it may well explain why a decipiens planted next to an australis in identical size is now double the size of latter. Apparently they compete with each other for the water, but available quantity for decipiens is enough and conversely not sufficient for australis!

Wow, thanks all, some relief…

 

here’s a live look at it right now from my vantage point in the water

Definitely no pool water is getting in there and a soil check of the area showed excess sodium present 😁

these definitely get a lot of water but it does drain quickly. They were grown in “lake Jesup mud” in Oviedo, FL

I guess I’ll just keep watching it

Update, this palm doesn’t appear to be petering out. It continues to Grow and the new growth looks fine. 

However, it’s one of two that are beginning to lose old petioles. 

Today I was cleaning up some things and a light tap on the petioles would send them tumbling to the ground. You can see the moist and fresh looking trunk that was under them. 

I did notice ants and/or other insects under them; is this something to worry about?

excess sodium!? Do you think that may be a contributing factor? 

 

I have some decoras and I think I was over fertilizing them when they were younger and it would make the leaflets dry out like I see in these photos. I stopped the fertilizer for a long time and it didn't really phase them not having extra food. Maybe you're loving them a little too much? But to me, the sodium threw up a red flag; but then I'm a west coast guy and conditions are totally different for us growing palms here....
