best way to try save this phoenix roebelenii

[Palmfarmer]

This phoenix roebelenii seemed to be doing great. One day i decided to try pull on a spear to make sure things were ok. on frond pulled out i tried the others and i pulled out all of them and a big hole remained. I then poured in hydrogen peroxide on 2 occasions during these 10 days. I went to check on it today and it looks like this. What is my best plant of attack? jank out everything in the middle there or just keep on going with the peroxide treatment?

perhaps cut of the brown parts?

Cut it back a bit more (leave the lower fronds) and keep using hydrogen peroxide on the growing point a couple times a week. Then the new fronds will pop and be fine. Cut down on overhead watering, especially during cooler months late in the day. If you have to use overhead sprinklers run them in the morning so the top of the plant dries out before evening.

I recently soaked it in peroxide today, but now it pouring down rain. I have never watered it overhead, but we are stll in rain season. I think its some delayed cold damage perhaps? cause my other Robilinis are fine. I never cut it I just yanked out the bad fronds and this came out a few days later. I will try to cut away the brown stuff. thanks

Did it fizz and foam up when you squirted the hydrogen peroxide on the growing point?

You don't need to use the HP on the whole plant, just the growing point. Here's a pic of one post pruning and peroxide applications on the rebound after a couple months.

Solid advice.  I had this happen to a pretty big  one (4 feet of clear trunk) after a freeze when I lived in the D.C. area. I did this same thing, it put out one very stunted frond, then started pushing new ones left and right and by fall, you couldn't tell anything had happened to it.    Good luck and keep us posted!
