Help with hurricane palm

[Stylo328]

I currently have three hurricane palms growing behind a Koi pond. One of the palms has significantly stunted growth. I have tried liquid palm nutrition, fertilize regularly, and have also tried pesticides. I would appreciate any help you could offer on diagnosing and addressing the issue. 
 

The other two palms appear to be doing fine. Although one does have some premature marking of leaves that might be indicative of some deficiency. 
 

Thank you in advance for any guidance you can offer.

Looks like insect damage originating near the growing point. It has a very similar look to what I had a number of years ago on some pygmy date palms. This followed a real nasty cold spell a few months before that.

Pour a small cup full of hydrogen peroxide into the crown and see what happens.  If there are microbes in the crown, it should fizz up pretty fast.

[Stylo328]

Thank you both. I have poured peroxide down the crownshaft several times over the past few weeks.

Did it and does it still fizz up?

It does not fizz really.

Where are these palms located? Do you have any overhead irrigation? Any whitefly on the palms or sooty mold. Check for whitefly eggs. I had some on my cocos and the leaves would get really black with sooty mold and attract other insects.

I had a similar looking issue (but not as bad) with a few beefy caterpillars crammed in the crown of the Roebellinis.  I couldnt extract them as the would retract down into the crown, so I just sprayed some of the pyrethrin based insecticide I had down there….  Problem solved.  The new growth was quick and normal after that.

That poor thing is all crudded up. I suggest you get some (in blue bottle and formerly Bayer) insecticide containing imidacloprid, mix it according to directions and pour it as a drench around the trunk of the palm. I'd also mix up some Ivory soap (not dish detergent) into a pressure sprayer of water and spray the solution all over the palm to treat for insects.

If there is no fizzing, definitely some kind of infestation as others have mentioned.  @PalmatierMeg's suggestions should help you treat them as well as get the soot off the fronds so the palm can produce more food.  Plus, she is close to you geographically.

[Stylo328]

Thank you all for the advice. I sent a note to PalmatierMeg Since we live in the same area.
 

Tomorrow I will swing by Home Depot to pick up some Bayer Advanced (blue bottle) and will also purchase some ivory soap to spray down the fronds. 
 

I will update the thread as she starts to recover.

One item of note, that led me to believe there might be some implication for borax deficiency is, that when I flush the filters for the pond, the water exits at the base of this palm and the one on the opposite end.

What would you recommend as the best general palm tree fertilizer for Southwest Florida? I’ve got a collection of about 50 to 55 palms, ranging in type and in size.

Lesco from Home Depot 13-3-13 palm and tropical. It is a slow release.

I had a similar issue to yours on 2 out of my 4 Pindo palms. Stunted growth, similar markings.  Both emerged spears that looked dysfunctional as yours.  I drenched them in fertilome systemic insecticide drench including down the crown. Looked like some kind of weavilles or burrowing bug came crawling out. 1 Palm started sending out crisp all brown spears and ended up dying, the other made it and looks normal now.

[Stylo328]

Today I sprayed some organic insecticidal soap on the heart of the palm. I did this while I look for the recommended insecticide (was not able to find it at Home Depot or Lowe’s).

This is what I used and this is what emerged and subsequently died. I believe there are more of these hiding inside of the crown shaft so I will be pouring in either the Baer advanced or Fertilome. 

I am also fertilizing the palms today with the recommended Lasko fertilizer.

Thank you all!

That’s some sort of jumping spider, a murderous feind no doubt, but not of palms.

I love fertilome products, I used the exact product you posted (for citrus) and other products with no visible success….leaf miner infestations drive me crazy!! Try dumping peroxide in the crown also. I get my fertilome at ACE hardware, cheaper than Amazon.  Also, those spiders (and others)  feast on the leaf miners of my citrus.  When I see them I know to check underside of leaves and sure enough… It may have been beneficial for the palm to have those spiders, Who knows. Systemic works the best (imo) because it kills what (if anything) is eating the palm. Peroxide fizzle means fungus.
