My Trachycarpus new leaves are bad, please help, disease, pests?

[Honza]

Hi,

I have a Trachycarpus Fortunei and all its new leaves are damaged like this. Transparent lines on the leaves, turning brown. Inside the center of the palm I found some beetles, woodlice, European earwig and other I don't know what. There were also some white eggs around.

I don't know what happened. The inside of the palm is quite damp. Could the beetles be causing this? Should I use some kind of spray on them? Or is the problem some bacteria, fungus and the beetles are there because of the humidity.

Thank you 🙏

Where is the roofline of the house?

Debris is getting into the emerging growth point and is negatively interacting with the soft tissue of the emerging spears. The insects aren't a real problem but are attracted to such things. It may be that the crown is picking up deposits from your roof. You can make a choice on how you want to clean that up.

The roof of the house it is not pointing in this direction. But it's true that only now that it's planted in the ground. About 3 months ago it was in a flower pot, where there was a mess falling on it from the roof, here and there maybe some moss, etc. I picked up the larger parts, but not the small ones. Moreover, it rained extremely hard all summer here too. So it would make sense that the mess inside the palm tree is rotting, it destroys the undeveloped new leaves and at the same time attracts insects. I'll clean it up and try to move the starting leaves a little apart so that it can dry out before it rains.Thank you 🙏

I don't want to gossip, but that really looks like dirt...

Jan, in which region or city do you live?
What is the climate like there (in your garden)? Even Trachycarpus fortunei can be too damp depending on its location in the garden...
I even lost one at my old location, even though it was USDA zone 8a, but we had an average of 1600 mm of rainfall per year and it was a little too cool and shady where I stupidly planted it. But mistakes happen...

Hello, 
I am in USDA 6b, Czech republic. So I'll put heating cables in for the winter and wrap it up. Annual rainfall is normally around 500mm. This year, especially the summer was rainier. It could have been the dirt in the middle of the palm tree. This year it bloomed for the first time and it's still its first year in the ground. So we'll see how it does in the future, hope cleaning the inside will help and the next palm leaves will be better.

I would spray it out(clean)with water, followed by a  hydrogen peroxide flush, and then remove residual moisture with compressed air.

  I would not want that  heading into winter in a zone 6(or 7,8).  

Maybe protect the top from rain, or hose water with something, but allowing air and sunshine in. 

Daylight is quickly winding down, sunlight is a great disinfectant .
