Re: Tall orinoco cold hardiness
Now you've got me interested.
You might want to consider burying some type of heating element or other heat pipes.
Around here,(deep south) people often use pipe heating cables to keep exposed plumbing from freezing.
I'm guessing that areas like yours with frozen sidewalks have invented heating element products that will warm the sidewalks and eliminate the ice?
Seems like all you really need is a heating element that will maintain soil temps at 30F or above.
My thoughts - maybe warm water circulation? or heat cable?
