Great idea for sustainable growth ;)
I have a pine as old as me in the birth house' backyard.
It's a common one here Pinus Nigra. Never tried the nuts :) but they're small one.

Cold & rains a not at all a problem for most pines... They even enjoy it as SPA :)
Drought you must keep off, especially in the first years.
Please keep the babies safe from harsh climate!
