This entry of 31°F is just to start the new topic. Five gallon under Acacia (high, open and light canopy). First year exposed to cold. No visible damage after one week.

Now I am sure this hybrid can take lower than 31F. Anyone who owns this hybrid can you please share your lows and experiences after cold winters. especially guys in the southeast :D:D:D.

Thank you in advance

Two nights in a row with a low of 19F.   ~36 hours below freezing.  Had covered with 1.5 oz frost cloth.  

 

Minimal spotting on leaves.  Was cold long enough to freeze the rocks holding the cloth to the ground.

Overall pretty impressed.

Sadly need to amend the post above.   Been seeing progressively more damage show up as time goes by, this one appears slow to show.  Now 1 week post freeze and have about 50% leaf burn (top halfs of all fronds).  Really hoping this doesn't progress any worse.  Still, given that Mexican fans in the area are completely bronzed, still impressive, just not as hardy I had hoped.

Two jxs 20f calm night out in the open, zero burn whatsoever. One has a 16" diameter trunk, the other about like a 3l bottle. The bigger one was a 15g last year and took 18f in a 15g pot and only had a touch of funky spear. Zero burn at that time as well.

Nice pics :)

Still dreaming for one of those :wub:

How many leafs they put on this year?

Good question, I didn't count.  They put on growth fast once they get their roots established. I fully expect the larger one to put on vertical trunk next year.

Texas heat should push them to grow quickly :)

Brief low of 22F last year, was covered with a sheet....no damage. Grew throughout winter and summer. North Florida Gulf Coast.

Mine has taken 21oF without skipping a beat (while 6-7 feet tall), so of the very oldest fronds get a bit bronzed but they would be getting removed anyways.  The spear had never pulled and it is now 18 feet tall to the top of the tallest frond, 23 feet wide canopy and a trunk circumference of over 7 feet and almost 3 feet in diameter. I think for sure when these get a good size they are probably hardy into middle to low teens.  Hopefully no-one has to test that.

      Here is an update on my Jubaea x Syagrus Hybrid that was planted in March 2015.  The palm is growing however I am not seeing explosive growth that I was expecting or have seen from others. So far so good though...  the trunk is very solid and this is mainly where I see most of the changes thus far.
      Here is March 2015 right after planting..

      Here is an updated thread about my JxS hybrid that was planted earlier in March this year.  First pic was right after it was planted and the next just this afternoon. So far so good !  No freezes here yet but it looks like that may change in the next couple weeks.. I do plan on protection as it is its first winter..
      Enjoy...

      I worked in the yard today and did some spring cleaning. My Satsuma I planted in spring of last year took a beating over the winter and lost all of its foliage.. the trunk really thickened up and the wood is still alive- but I decided to remove it and make it an indoor outdoor plant. The dry cold is just too much for the foliage. Crispy leaves everywhere and even if it regrows I am not sure I want to be raking every spring.. so to the pot it went.

      In its place I put in a Jubaea X Syagrus.

      The palm is located facing south... and most likely the warmest part of my landscape near the center of my house protected from northern winds. It is in full sun..


      'The Alpaca' right after planting. So excited about this hybrid !
