looking for a nitrogen fixing tree for my area (east coast of canada, bay of fundy, zone 5a) I have about 30 fruit trees planted so far in 3 different areas on my farm, Apples, Pears, Plums, Cherries, Peach and Apricot. I am planting in guilds designed to come together over time, but I still haven't nailed down the large N fixing chop and drop element.
I have grown out honey locust collected from trees my area but the spikes are pretty gnarly. I am a barefoot farmer so that has been ruled out for me, gonna dig up the ones I already have planted in zone 2 and move then to a zone 4 area and hope that they don't grow back form any roots I miss. I have a few sea buckthorns bought from the nursery, but they haven't really done very well so far on my land. I started a bunch from seed this spring so hopefully they will be more productive that way. I have a couple of siberian peashrub which look promising, but its too early to tell.
I guess I am really wondering if anyone in my climate has had success using speckled alder as the n fixer? it grows in the wetter spots of my site and is the first to take over old fields in this area. I know my dad and grandfathers would think I was absolutely nuts for actually planting speckled alder, but maybe that is the sign that its the right thing to do from a long term soil building standpoint? following natures signs instead of fighting them?
