Help.. Washingtonia robusta

Recommended Posts

Adam Halford

Hi I was wondering if anyone can help. I grew some washingtonia robustas from seed and were all doing really well.. I’m using a mix of fine seed compost, coco cour and perlite. All were doing fine but over the last couple of weeks they are now shrivelling and loosing colour. They are around 18 months old and have been kept in a conservatory during winter and outside in the summer in the UK. I repotted yesterday as roots were coming out the pots. Any help would be appreciated

Something about their environment changed drastically to get them in that state of dessication. Now you have to figure out what that is, and correct it.Maybe return them to their spot in the conservatory for now,to see if they improve.

Possible causes:

1.In the picture,are they parked in front of heating vents? Hot air blowing on them will kill them in short order.

2.Did they go from the conservatory to direct sunlight outdoors?They need to be introduced gradually to full direct sun to acclimate without burning.

3.Have you fertilized recently?Either in the new potting mix or in the water you are supplying.You may have overdone it.

4.Did you soak the pots in a bucket of water after repotting to ensure there are no air pockets in the mixture, and that the soil mix was thoroughly and evenly hydrated? Roots can't pull moisture out of dry pockets in soil or thin air.

After thinking it through,one of the above mentioned scenarios might sound familiar, and may help you solve your mystery.Mexican fan palms are very strong growers and you almost have to go out of your way to kill them.

Hi pal thanks for the reply... they are not heating vents they are just cavity vents... that is the spot they was in... they have been there all winter and been fine.we have had some hot weather over here the last 2 weeks so I moved them outside in the day and bought back in overnight. Obviously with the current situation I’m home everyday and I misted them regularly. They had turned like this before I re potted them. I fertilised them in April -the first time of the year.. and only a bit in each pot till it started running through. I used palm focus. I caught my puppy. Chewing on one of the leaves the other day-wether she went at both? It’s strange they were doing brilliant considering they are 2 years old? I’m using a potting mix of loam, perlite, coco coir? I gather that’s ok?! This is another from the same batch of seeds? Puzzling me? I only water when soil is dry 1-2 inches down... probably every 2 weeks?!

I would love to listen to your comments in original English accent.  I believe your Washingtonias will make it. Do not mist them. Washies love dry climates.

Here's a video for reassurance:

How often should they be fertilised? I usually mix a 2 litre jug and pour till it runs out of the drainage holes then stop and do the next one the same, is this correct? I’m fairly new to this and just trying to get a system going.. have 50 more seedlings growing in community pots I will need to pot on when the weather changes I don’t want to loose them

      Thanks in advance for any help. I have this planted on south side of home in Zone 9a - Gulf Coast. Planted in Spring of 2021 and while it puts out new growth, recently its developed this rusty/splotchy coloring on most of the fronds. New growth still comes out and looks great but pretty quickly gets this rot-looking color. Any suggestions on what this could be? I have sent pictures to my local extension office but they basically sent me to this website.

      The spear stops extending and shrivels up, then base of spear turns out to be yellow!!! But all of old leaves remain greeen and normal.
      What happens to it? We've got 20~30℃ here, with 50-90% humidity. Is it a fungal infection?

      I've had this Christmas palm (Adonidia merrillii) for about two months.
      Can someone help me identify what's amiss here? Is this a disease or something else?

      I don't know what is happening with my small Sabals but they don't seem to look ok at all.  This whole thing started since October I guess when the temperatures stated to go down but there hasn't been any freezing in the Houston area ever since. I will post below some photos with them, maybe someone has any ideas. I want to treat them with H2O2 because it seems that they have some rot on them, at least this is my idea. If you have any ideas please help.
      I tried to pull the spears and I could not do it at any of them.
      Indeed, these are all on the side where it is shadier but they still get some sun and in between the ones that seem not to be doing so good I have some that don't have any issues at all. It is just like it is happening random. 
      Sabal Palmetto, at first one of the leaves was coming out yellow but it managed to get some green under it and it pushed it out. The newest spear came green from it.


       
       
       
      Sabal Riverside, it has a few spots on its leaves and the newest spear seems to have some problems.



       
       
       
      Sabal Palmetto, almost  of its new leaves that have grown since I planted it are dead. The new spear seems to be green.


       
       
       
      Sabal Palmetto, all of the new leaves that it sprouted since it was planted are dead. The new spear that is coming out seems to have a green base.


       
       
       
      Sabal Palmetto, all of the new leaves that it sprouted since it was planted are dead.  Also, the newest spear coming out seems to be dead.


       
       
       
      Sabal Riverside, again it seems to have some issues, the newest spear seems to have some rot on it, something that looks blueish greenish as you can see from the below photos.



       
       
       
      Sabal Palmetto, the one that I got from our colleague @Reyes Vargas that was doing so fine, sprouting leaf after leaf and now it seems not to be doing so good anymore with its newest spear dead.
