Would you mind posting some of those pics individually?

Every time the pics come up before I can really look at
then the page changes and never comes back.

Sure, it didn't turn out like i would have hoped. Giving it a different approach...
This is my 6 foot Dracaena tied up and wrapped in rope lights. This is the same protection approach I use on my larger palms, including my 4ft trachy and 6.5 foot trachy. Notice the thick layer of mulch I lay down before putting the structure over the plant.

Dracaena tied up

Thermostat secured to metal pole alongside plant and set at 40 degrees.

Lattice bent into cylinder shape and secured with zip ties...

Insulation lining the inside of the cylinder, held on with bungee cords.

Put structure over the palm/dracaena...

Cut sheet of lattice into strips for the roof/top

Bend strip of lattice into arch shape and secure the ends to the cylinder structure, making an arched top. This is great for repelling snow/rain. I continue with the insulation to the top, leaving the very top open for light(not sure if it's a necessity though). Finish with covering with a large clear plastic furniture bag and secure around the structure with bungees. This process is good because if plants are getting too tall, you just add another cylinder or half cylinder on top of the original to make the structure taller. They look like mini silos when done. If you live in a zone that's colder than mine, just put an extra strand of lights in there.

Great idea!

have you used the cables wrapped around it like that before?

I hope it doesn't get hot enough to burn it.

I am thinking of trying this sometime-

I wonder if wrapping it with a little burlap and then the
cables would be a good plan.

Have you seen these before?-Li

The T-3(I think)turns the power on at 35F and off at 45F
and they are pretty cheap-let me know what you think
and best of luck with the Cordyline(?)

Hope I don't sound like a dick

No, the rope lights don't get hot enough to burn the foliage. Yes I have used them before, along with regular christmas lights.

I'm sure the cordyline will be fine, it's done well the last 2 winters in ground, and just keeps getting bigger faster and faster.

I've heard of the thermocube before, but never seen them. Looks like a good buy for the price, similar to a thermostat.
