Nitrogen fixing bacteria for Alder trees

[Joanne Vaughn]

I am thinking of starting some alder trees from seed for planting into an area that does not and has not hosted alders.  How can I gain the nitrogen fixing bacteria for inoculation of the roots ?

Hey Ely, I did some research and according to go botany the speckled Alder is also nitrogen fix. Could you send me some seeds of that Outdoorsman's nightmare?

Hello Freyda,

I don't personally have any alder seeds in my collection, and they don't ripen in the woods, until fall.  I did find a website that might be helpful, though.

1,000 seeds for $15 is pretty reasonable for trees.  I haven't done business with these people before, but I have had good luck ordering tree seeds online, in the past from other companies.  They are out of Swanton, Vermont, so presumably the genetics would be compatible with your climate, if you live in Upstate New York.
