Time to call in the palm gurus, it’s got me this one whatever it is. Nutrient deficiency to wet to dry to cold to hot or not enough of something. Fungus or some other ailment. Iam leaning towards nutrition but if I knew that I wouldn’t be asking this question. Is it bore water and they don’t like high iron? But I just can’t shake what is going wrong. But the napaliensis dont like something and that something is wrong, whatever iam doing iam not doing it right. It’s most likely something simple, like they say the kiss method keep it simple stupid!

Looks like potassium deficiency. Langbeinite(sulpomag) is what I would apply. The more you water(or the more it rains) the faster you lose potassium. The only way I avoid this in my sandy soil/subtropical climate is by using osmotically controlled release fertilizer. I suppose it might also be an insect attack, but I have not seen one like that. Potassium deficiency is often spotted like that due to the immobile nature of potassium in a leaf(Mg does not look like that its not spotted). The langbeinite will also help with Mg which also can rinse away fairly quickly. That is my 2 cents.

Are those outdoors or in a greenhouse? I only say this because at least here in Southern California I seem to have much better luck with them outside than a greenhouse. Don’t ask me why. My neighbor has the same experience

Here are two beccariana seedlings I rescued from the green house that are now recovering outside. Followed by one (foreground) which was germinated on a heat mat and put outside straight away. Same mother plant, same batch of seeds.

It’s a good point. P napaliensis does well outside here and I’m in a cool climate. It’s seems to be similar to Pritchardia minor in preferred conditions so far. It might be that any nutritional deficiency caused by being too warm to ideally absorb nutrients?

@happypalms I can only say I haven’t observed similar for my P napaliensis down here in the fridge 🤣

But, that’s looking good.

Bret, interesting observation.

Possibly nutrient I was sort of leaning towards that conclusion, however after talking to @palmtreesforpleasure he was saying get them outside and plenty of air movement. He also said try some in the greenhouse and some outside. Time will tell, iam not fertilising now due to the he cooler weather. So for now some outside.

Yes they are in a greenhouse. I have a pritchardia martii that has similar symptoms but not as bad. It’s outdoors in the ground. I do have boredom water that is high in iron is it possible that the iron is the cause of the situation?

Maybe the cold weather is doing something good for once!
