Jay,
I am about 20 miles from Edmunston. Definitely north, being zone 3. Planted some apple root stock, clematis vines and Hazelnut/filbert today. Will be getting a survey on the property this summer in anticipation of planting special hybrid chestnuts from the Connecticut Agriculture Experiment station. The trees will be ready to go into the ground by June 2014. This week, plan on counting maples and cataloging the varieties growing to get a better idea of the microclimates and what I will substitute with polyculture in those areas. Next spring will begin the vitis (grape vines)propagation for rootstock using a beta cold-tolerant grape variety. It is surprising how many varieties of cold-tolerant grape there is.
This fall will collect apples from various cultivars here in the St John Valley to grow my rootstock. In 1 year will plant them out below the swales and in 2 years start grafting multiple cold-tolerant apple varieties. The local town of Fort Kent is getting a farmer's CO-Op started here on Market street that I will be able to sell fruit, maple syrup, honey, nuts, and intercropped grains.
This fall I plan on starting my seed beds for the apple rootstock, Siberian, Himalayan and Korean pine nuts, blueberries, elderberries and bilberries. Next spring will be the stone fruit, peaches, nectarines and apricots. The Manchurian Apricot should do well here. Will slowly add in the Nanking cherry, hardy pears. Once I get all the rootstock I am going to use multiple global hardy varieties for grafting.
Looking at getting some Osage orange and use these to graft some che fruit to see if it will grow here. It is not unusual to hit minus 40 F here in the winter. I will have to plant a lot of each to have plenty for the marauding bears, moose and deer to have their share and not destroy all my crop.
