Looking for some suggestions for some "Permanent" blend I can make for my trachies. 

I have acess to the following materials:

 

Biochar

Pumice

Vermiculite

Perlite

Coco Coir 

Compost

Real soil (loam) 

Bark chips 

Lava rock

I find an almost succulent mix with perlite is a good draining mix for palms with a bit of coco peat mixed in 

I've only been doing this for a few years, so I don't claim to be an expert.  But Trachycarpus seem to do best in nutrient rich soil that is rich in organic content with high moisture retention.  They tend to do well in larger containers than most palms, so that they have more room to stretch out their roots, and they seem to prefer wet soil over dry.  I would save all the porous, geological additives for the pickier palms.  Trachycarpus normally do fine with cheap potting soil, in my experience.

in agreement.  I like to mix in larger perlite or pumice to make it last longer on bigger palms.  This palm grew about 1.5 foot of trunk in the pot in a year

I just got inspired by the channel called Swedish Plantguys that grew a Trachy in pumice coated with clay. They used a water resorvoir at the bottom of the pot. 

According to them root growth in Pumice is 4 times as fast as other mediums. Then again that could be just advertisement for Pumice. 

Currently my trachies (think they are nanital) in 3 different mixes. 2 with 1 part compost 1 part coco coir and 1/5 part fine perlite. The last one grows in black gold type soil and woodchips arounf 30-50%. The latter has grown the best. 

I have some new pots ready now that is roughly twice the height of the ones they are currently are in. 

In those I wil pot them up with 2 parts peat moss 1 part Pumice and 1 Part Perlite. This is what Gary from laguna Hills Nursery calls Acid Mix. Usually ment for berries and other acid and water loving plants.

Have you tried growing washingtonias in a stone mix? Should be ideal in your climate. They can be a little tricky in pots I find though. 

In the ground these need clay based soil. In pots, the best is 100% Seramis (clay gravel). All my trachys do great in this.
