Just an update of a comment two years ago, above. I always had problems with orange leaves. Some people said it was normal for the species and others told me it was due to insufficient fertilizer. Recently I have been trying to fertilize monthly using slow release 22-7-14 with micronutrients. Plus generous doses of pee. Don't scrimp on the urine! I have not bought fertilizer since the Iran war started, so I have no idea what it costs now, but pee is always a bargain. I still have some yellow-orange streaks in the older fronds, but overall I think it looks much better. The reflection from the perpetually wet glossy fronds makes it hard to see the underlying green. After a terribly dry 2025, I'm up to 94" (2.4m) of rain so far in 2026. If you are wondering why these don't look as good growing on the mainland, abundant rain is probably a contributing factor. The new plantings nearby are growing like gangbusters. For scale the larger one on the left has about 9 ft (3m) of trunk. After 5+ years of blooming, still no hint of fruit. A recently added Pigafetta with black bristles is lurking in the rear. As hard as it is to believe, FB produced the seedlings that grew into the 4 ft tall baby on the right starting with seeds collected in 2023 at the famous Carlsmith garden. With the proliferation of private palm gardens since around 1990, Hawaii is able to produce seeds for hundreds of rare species. Even for species that struggle to set seeds like Phoenicophorium, there is almost always somebody who has a tree with fruit. Judging with how quickly tropical forests around the world are being cleared, this might be just in the nick of time.
