I'd leave the dead fronds until you see if the plant lives. If it does, probably late March/early April is a good time. If not, you don't have to worry about trimming the palm, you can just remove the whole thing. Yes, some still do. I attached some photos. Picture one shows some of the stems of the fronds where they have something black growing on them Picture 2 is one where the fronds that were growing in pulled right out (I believe that means it’s dead) picture 3 shows some black almost mold that’s crowing on some of the fronds that are bunched tightly together... been putting hydrogen peroxide on for over a week every other day, wondering if there is anything else I should be doing 1 Quote Share this post Link to post Share on other sites

Since it isn't that expensive, I'd keep giving it a douse or maybe perform a little surgery to see if there is any living tissue in the crown. Quote Share this post Link to post Share on other sites
TylerA 4 Report post Posted March 2 I will keep giving it some, I have 7 total palms, this is the only one where the emerging fronds have just pulled out, so I’m hopeful that the other 6 still have some life in them and I keep treating them, so I’ll just keep giving that one doses every other day too.

TylerA, I am in the DFW area. I tried Mexican Fan Palms for a few years long time ago and I gave up! They grow fast and they are pretty, but DFW winters kill them easily. Lots of work, hope, and always disappointment at the end. Now, I have beautiful Windmills, Chinese Fan Palm, and Texas Sabal. Sabal went through the freeze undamaged. Windmills and Chinese Fan Palm have all fronds dead. The race has started! What will be faster: rot, or growth and pushing the rot out? I sprayed my palms with copper and poured some hydrogen peroxide. We have a sunny and warm weather so there is hope! S. 1 Quote Share this post Link to post Share on other sites
smatofu 58 Report post Posted March 3 Take a permanent marker. MAKE A HORIZONTAL LINE where spear emerges from the trunk. The line should be across the spear and some old frond stems. If you see the spear moves up relative to old fronds, your palm is ALIVE! It may take few more weeks of warm weather. Quote Share this post Link to post Share on other sites
TylerA 4 Report post Posted March 3 Yeah, I’m in Houston so our winters aren’t as harsh typically, but this one obviously was unprecedented. I have 2 sabals, 4 Mexican fan palms, and 1 windmill. The two sabals and windmill look like they will make it, however the 4 fan palms are pretty rough, just hoping I can rehab most of them and get lucky.

All well meaning and personally, I employ all three ways of approach. Thank you Alex! All good advices in the videos! I would start from the least intrusive method and progress to more drastic stuff. 1st - drenching with fungicide/bactericide; the last - trunk cuts. Again, mark the spear with a line. If it moves up in the next few weeks, your palm is alive so you can leave it alone. Edited March 4 by smatofu Quote Share this post Link to post Share on other sites

TylerA 4 Report post Posted March 4 I trimmed back all the dead fronds that were completely brown and dead, however the spears that were emerging won’t pull out, I’m guessing that’s a good thing? I poured copper fungicide in around them, hoping that helps. My main concern is the black mold/powdery substance on these new fronds (pictured below), I’m trying to tug them out the best I can but they are not budging... assuming the tree is alive it will push these out on their own and I can cut them back when they are out and it’s safer? Curious how I should handle those given they are clearly not well and may get the rest of the tree worse. I have pulled as hard as I can to remove them with no luck, any other strategies? Or just leave them? 1 Quote Share this post Link to post Share on other sites

If you don't see growth in 2-4 weeks and you want to cut, then you can do it. [My main concern is the black mold/powdery substance on these new fronds] I wouldn't be concerned with what is outside the trunk. You can cover the trunk when it is raining. Paper trash bags may be good to cover. Actually, as I am thinking about it, I will cover my smaller palms with paper trash bags every night. It will keep them warmer without overcooking.

So that raises another question, 3 of my other Mexican fan palms had the spears pull, I did hydrogen peroxide, then copper fungicide a day or two later. I know it’s important to keep the crown dry, but isn’t the fungicide in there keeping it wet? I’ve been using a Turkey baster to suction water out, but I went out in the morning and the fungicide is still sitting in there too, should I leave that? Or suction that out so it stays dry? also should I fungicide or peroxide again in a few days or weeks? Or leave it now and see what happens? Quote Share this post Link to post Share on other sites
smatofu 58 Report post Posted March 5 [but isn’t the fungicide in there keeping it wet?] Yes, it is wet, but there is a good ratio of fungicide in the water, so I guess it is OK. Rain water would dilute your fungicide. [also should I fungicide or peroxide again in a few days or weeks?] Supposedly, copper fungicide can be harmful if palms are treated too frequently. My palms spears are sitting tight. Visible spears portions are completely burned by frost but they are dry and without any signs of rot. Quote Share this post Link to post Share on other sites

We just moved to Hot Springs Village Arkansas after retiring from Iowa 1 1/2 years ago to escape the snow and cold! Last June we purchased a 12 ft Windmill Palm for our anniversary. They said it was cold hardy. Well, as you know we just had record snow and low temperatures. We had below freezing temps for 10 days straight with the lowest -5 at night and 11 during the day. My husband put some fertilizer down and then we covered the base with burlap and also with a moving blanket. Then the snow piled on top. We just were able to dig the snow off and remove the covers. What do you think our chances are for survival are since it hasn’t been in the ground for a year. And what to you suggest we do to help it along? I called our local landscaping business but I don’t feel too confident in their knowledge. First picture is after the snow. Second picture is during the snow. Third picture is after we had it planted. Thank you! Quote Share this post Link to post Share on other sites
Gaga Iowa/Arkansas 8 Report post Posted March 7 (edited) Hubby went up and checked out the crown today. We were very happy to find out it was hard and dry as a bone in the center! He tried tugging at a couple of the palms and they seemed pretty firm so we decided to leave well enough alone. We are going to give it a drink of water tomorrow, go forward like we always used to. We are pretty sure we see some green yet at the top yet. Finger crossed for survival! Edited March 7 by Gaga Iowa/Arkansas Quote Share this post Link to post Share on other sites

I wrapped the palms in old style C-bulb Christmas lights and then wrapped that in moving blankets. Austin Texas area got down to 1-degree and I lost power for as long as 4 to 6 hours. So we will see. Any recommendations? I will post updated photos later today Thanks. Update. Two weeks and one day after the long deep freeze broke. I trimmed them up. Maybe I need to trim more? Thank you all for the advice I have been treating each of the hearts of the trees with hydrogen peroxide one every other day. I can hear the fizzing inside so I’m going to keep this up for the next two weeks unless someone here says that is too often. Some green in the heart but I may be overly optimistic.

[when should I know if mine is growing? ] Take a black permanent marker and draw a horizontal line across the spear and some older stems. You can draw multiple lines in multiple places. By looking at the lines, you will easily see if the spear is growing. Growing spear = living palm. I see about 1/2 inch of spear growth per week on my palms.

Spear - still no movement. I don't really know what to make of it. I was expecting the spear to grow faster than everything else... Maybe the palm just needs more time... one 6-ft windmill - no spear pull; no spear growth Obviously, sun and temperature are 2 big positive factors. I have a feeling the situation would be much more dire if we had cold and rainy days. Edited March 15 by smatofu 1 Quote Share this post Link to post Share on other sites
