What do you guys think Filifera or Robusta?

[Ltapia]

Just got this today I was thinking more Filifera ??

Hybrid, the thorns and red streaks on the petiole along with robusta level stringy stuff are the key things to look for ideally a filifera has smooth petit olds with little to no thorns, perfectly green leaf bases and limited strings

Strong filifera hybrid, fertilized.

Any color probably goes away in our soil, more alkaline.

Almost pure.

Yeah, the leaves are real pale though it’s hard to say if it is a hybrid, I must be Filifera dominant

So hybrid you think ok.

Thick trunked hybrid, strongly filifera

Root bound, free it!

I only say hybrid because of the colorization on the petiole.  It is my strong belief that soil(ph) is also a player in the color.

So it’s possible the soil is causing that hint of brown ?

Seen it with soil and/or fertilizer. 

Acid vs alkaline

These are TorC filiferas..

Oh wow would this be hybrid filifera dominant or pure?

For me, I have seen colorization after fish emulsion, amended soil, fertilizer. I have used grass winterizer lightly with no color change. 

Or do pure have colorization? As this pure in a native grove from palm canyon shows.

 Kofa native filifera palms have no thorns.

So it can get confusing when younger.  Seldom discussed is the petiole base width. Extra wide on filifera, not so on robusta.

Even when robusta are over 40' tall with trunks 1' wide, or about the thickness of the young or c/ palm canyon filifera.

Pure soil or amended?

Fertilized?

I can turn color on with application of fish emulsion (acidic). 

I also see the coloring nearly disappeared on the newest petiole(s). In my mind those TorC filifera are rooting into that native soil.

I guess unless one personally collects seed at Moapa Warm Springs, there will always be uncertainty.

This is a pure filifera.. as near as one you can find..the fronds are also a pretty good indicator.. kind of hard to describe but they also have a pleated "m"..pretty uniform.. when larger. A good way of knowing .is when it starts to damage from freeze..  Roughly here's how it is.. depending on duration too..

Robusta ~20-22f

Robusta x Filifera hybrid ~17-19f

Filifera x Robusta hybrid ~16-19f

Filifera ~13-15f

These differentiated hybrids exist..

I never amend my soil.  If I get a trachy I think I will however..

They are fertilized but not consistently.. (need to get better at that)

Appreciate the info on defoliation temps I will save this ! When you used the wall o waters would you leave the top open exposed to the elements ?

This is the 2nd one I got too I didn’t post the picture . They might be too small to identify .

My full sun trachy gets coffee grounds when I drink.  Couple times a week? That's it.  It is on the edge of my postage stamp lawn, that's where it gets it's water.  No amendment.

It has roots six feet out from the trunk under the lawn.  So I imagine it would outgrow most amendment. 

What I like is no worries about leaf damage until maybe mid single digits.

Sleep easy!

They like a reliable and consistent source of water. I know you know this.  So that would be my consideration for placement of a new one.  Good to go, sun or shade!

I don't directly fertilize, but I do some little mulch worked into the soil on occasion. Pomegranate peels and such!

Some of my many failures I feel have been due to past fertilization. Or maybe more precise, my misapplication of fertilizer.
