We just recently finished planting 69 nut trees and 4 fruit trees, totaling about 3 acres!
The types of nut trees we planted are:
Korean Pine Nut
Hybrid sweet oak
I know what you’re probably thinking but yes, you really can grow those here in central Ontario. I must admit that the pecan is really pushing the boundaries of cold hardiness. The variety is called “Ultra northern pecan” and is said to be hardy to our zone. The botanical gardens in Barrie Ontario apparently has them growing, so we should be able to as well since we are in a slightly warmer region.
The almond is a russian almond, and is hardy to zone 2, which is 3 zones colder than here at Greenshire.
The persimmons should have no trouble growing but we may not get the heat they require for ripening of the fruit. We plan on placing rocks around the trees to further increase the warmth of the immediate area around.
The rest of the types of nut trees should have no trouble growing and producing for us. We’ll know in about 3-5 years, which is when they are set to start yielding a crop! We gave them the best microclimate we could provide with good wind protection and cold air drainage, so they should do just fine.
To mimic the natural patterns of nature, we have planted hardy native pioneer trees close to our nut trees. Pioneer trees are usually the first to move into open areas like the places our nut trees are planted. Pioneers establish good soil and microclimate conditions for things like nut trees to follow after the pioneers start to decline and/or die.
The pioneers are planted in a semi circle around each nut tree on the north and west sides, which is where the strongest and coldest winds come from. They will take the first hit of wind, which will ease the burden a little from the nut trees. Periodically we’ll cut back the pioneers and use those prunings to mulch the nutters. This will also fertilize them and keep the pioneers from overcrowding/shading them out. When they’re pruned up top, the pioneers will compensate below ground by shedding some of their root system. This will decompose into the ground, releasing fertility to the surrounding soil.
