At the risk of asking a dumb question, would it be possible to grow Pecans in my location (Z5a, 8300' elevation in the Eastern foothills of the Rockies). Apples do fine here, stone fruit is a maybe, all with some additional irrigation. Min temps are -20F (as per the zone), and lately we have not been getting that cold. More of an issue is our somewhat dry winters and winds, as well as rapid up and down of temps in the spring and fall.
Anyhow, in reading this thread I see some thought that it might be possible to grow pecans into Z4b. Being in 5a that gave me hope, but I was curious if folks really thought they could make it here?
If you do, which varieties would you recommend and where might I buy them?
