I got this plant from Nigel Kembrey of Hardy Palms in the UK. Produced a few new leaves which were fine but the latest leaves look crap






Yep... even the new unopened leaf looks yuck. My max low this Winter was -3.5C but the palm has been mollycoddled in my greenhouse. So no cold damage. Any ideas on what caused this damage.?
My only thoughts are the extreme hot weather(by UK standards ) we experienced last July/August what killed some of my Schefflera and a Daphniphylum. Previous to this we had a very prolonged cold spring that went on until early June.

Andy,
Maybe Jim will chime in here as he's got considerable experience with Princeps.
Mine are just babies.

Hope it outgrows whatever...it's a great size.

Regardless the species of Trachy, the characteristics are the same. Not the new spear, but the damaged newly opened spear seems to have have fought off some organisms and pulled through.

Thanks for both of your replies. Yes there are various discussions at the moment on problems with Princeps particularly canker at the basal area of the palm which leads to gradual smaller leaves and in some instances death of the palm. At the moment mine isn't showing this but 905palms could be right with some nasty organism attacking the spear. My two planted "blue" princeps look ok at the moment.
Here's one of them, pic taken last week.

You have multiple problems. Your potting mix is low in calcium; a fungus is attacking the soft, new growth; your potting mix is probably too wet because you have a boron deficiency.

I would repot in a mix of perlite.whatever your fav mix- and some limestone chips.


Looks like it is in peat

I've seen adding limestone mentioned here and there in posts. Is that something that should normally be included to add to palm soil much like fertilizer from time to time?

If so, how much and often??

Also, Steve mentions the addition of Calcium. A one time thing? or something to do from time to time and again, how much and how often..and in what form? Eggshells? powder from a pill?

Hi Andy

no idea on your palm issue...........but perhaps something other than heat got to your Daphniphylum? Members on the Hardy Palm board grow Daphniphylum in Atlanta, GA! Now that's hot!

Hi Tim.... not sure what happened then but many of my evergreen leaved plants got burnt all at the same time. We went from cold to hot in a short space of time. May not have been adequate moisture in the sandy soil that they grow in? Here's the Daphniphylumm with burn

The Schefflera Rhododendrifolia just out of main view was unaffected.
Apologies to palm fans but to update on the Princeps Hybrid it is grown in free draining soil not peat. I am planting it out soon and we'll see how it goes this Summer.

Hi Andy

I have no clue why your BLE's got burnt.....likely climate issues like you mention. PS, that S. rhodo is a beauty! I wish someone in the states would sell that one.
