Are there any other Zone 5a palm growers out there?

[SALOttawa 56]

I live in Ottawa, Canada. I have been growing palms for about seven years in pots. This year I am trying my first palm planted in the ground and overwintering it outdoors (with protection, of course). It is a washingtonia robusta. If it survives the winter, I will be planting two or three more in the spring. I also want to try a couple of Trachycarpus Fortunei. I am also trying to overwinter some musa basjoo and a dracanea by covering them with mulch. I also have a yucca which has been outside for three years now with no protection. If you have experience with any of these in zone 5a, or less, I would love to hear your experiences. If you want to check out my yard on YouTube, search Constance Bay Palms.

I'll I can say is get pop up greenhouses and be prepared to heat them when needed ....Trachys will take 10 degrees but that's not with frozen soil..and continuously subjected to freeze after freeze ...just my 2 cents.

Will also contribute my 2 cents here. Probably the hardiest palms in the North are Sabal minors, Raphidophyllum hysterix (Needle palms), and Trachycarpus fortunei (Japanese windmill palms). I don't like Needle palms so they will just not grow for me even if I were sever zones warmer. Sabal minor 'Louisiana' is one of my favorite S. minors as it is a robust grower and cold tolerant.  My favorite trunking palm is Trrachycarpus fortunei (Japanese windmills).  In the Mid Atlantic, I would say they are hardy to 5 F (higher sun angle, longer days help),  but agree with Hutch, they will not tolerate frozen soils for weeks on end.  I didn't 't protect my Trachy at all this winter, it's on the south side of the house and it's been ridiculously warm so far. Trachys are so easily from seed, that I have two dozen in reserve in case there IS some freakish arctic vortex. Happy New Year!

This pic was taken after 1/4 inch of snow recently, but otherwise, it's been very mild.

Did you pick W. robusta because of James Palms YouTube success in the Toronto suburbs by any chance? 

Ottawa is significantly colder than the lower Great Lakes microclimate and so they may need serious heating more than just a good box and christmas lights. 

It's surprising how well they do in toronto, and the big Sabal Palmetto tree, given the chronically cold and wet soil, but Washingtonia are the fastest growing, 

at least of the hardy palms, and are tough enough to come back from damage. 

Remember that cold hardy usually refers to zone ~7b thru 10a, and that 5 and 6 are deep lost cause territory without significant heating measures, including 

the inevitable deep ground frost encountered there.

Hey! Thank you all for responding! We haven’t had any super cold weather yet, but I think I am prepared.

If you would like to see my setup, check Constance Bay Palms Zone 5a on YouTube. I did learn a lot for James Palms, but the Green Dragan is truly inspiring. This is my first year over wintering my washy. If you check out my videos, I have the Christmas lights for the tree, plus some heating plumbing wire to keep the ground from freezing. I have already ordered two more washies for the spring as well as some more trashiest, and a butia capita. I have about fifty 9 month old washies at home that I grew from seed as well as about seven trachies. I also have a number of palms, bananas, pineapples and a bird of paradise that can’t handle the cold so I bring them in for the winter. I am trying two musa basjoo outside as well as a dracanea with only mulch as protection. I just got a new three foot bird of paradise today as a rescue. You can see them all on my videos on YouTube. Hopefully I can find more people doing this in zone 5 so that we can share successes and methods that  work. Thanks again for your responses. Happy New Year!

I have about six more videos as well with more to come.

I think your Trachycarpus is doing great! What is your box covered with? What zone is it that you live in?

Hey, i live in Montreal zone 5.  Here is a little update of the box as of today January  16th.   its -15 right now.
Think it looks good so far. 2 more months and i'll take the box down.  Its my first year trying it :D so far im happy hehe.
Realize my washi was getting dry, i tried to poor some water  just a little but mostly went everywhere but on it lol. 
hope it wont affect my palm.

My box is made of R5 foam just as Jamespalm videos hehe.

I have a C9 plug to a thermocube and another C9 pluf on a smart switch  just in case the thermocube isnt enough.
1 have 2 smart temperature and humidity sensor
one on the crown and the other one on the ground nearby.

Excuse the weeds everywhere lol


Voila

Nice! Zone 5 a or b? If you grow a washy, I would go with a full 8’ box. You are probably ok with a small box for a trachy. They grow really slowly and are super expensive to buy of any size! With my box, I have two roofs. One is inside and I will raise it every year until I have to extend the box. How old is your large trachy? I have a 3 year old which is a bit smaller, I think. I will be planting it this year.

Looking good...!..Palms make people happy.
