We constructed two high tunnels and planted over 200 apple trees and a handful of other fruit trees and berries in 2007. We lost one of the high tunnels (winter of 2010) and will not be replacing it. Many of the trees inside survived the collapse and we are interested in seeing if they will survive the winter without protection. We have just completed our 4th growing season (2011).
We have been testing over 30 apple varieties both inside and outside of the high tunnels. These varieties include the following:
8919, Prairie Sensation (18-10-32), 18-8-9, 21-61-69, Advance, Alice, Altaiski Sweet, Arbordale, Arctic Red, Brookland, Carroll, Chinese Golden Early, Collet, Garland, Golden Uralian, Goodland, Heyer 12 and 20, Lee 12, 17 and 20, Norcue, Norda, Norhey, Norkent, Norland, Norson, Northland, Novosibirski Sweet, Parkland, PF-12, Prairie Magic, Prairie Sun, Red Heart, Rescue, September Ruby, Summer Red, Trailmen and Ukalskoje Nalivnoje.
All our varieties are grafted on a Siberian roostock that is winter hardy to about 40 below zero.
Our trees were grafted by Dan Elliott who has a small orchard in Wasilla. We also obtained our rootstock from Lawyler Nursery out of Montana.
We planted several berries both inside and outside of the high tunnels, but only the Sea Berry (female), Honey Berry and an Arctic Raspberry survived inside the high tunnels.
