Are Sunchokes/Jerusalem artichokes good for planting near aspens and cottonwoods? Do they fix nitrogen? Thank you!
I live in Driggs, ID, 6000 ft of elevation, rocky mountains, dry, windy, cold in winter and intense sun in summer.
Aspens and cottonwoods fix nitrogen. I am pretty sure that sunchokes do not. As long as the soil is well draining, and they aren't in deep shade, the sunchokes should be happy campers. This season I did an experiment and planted some sunchokes in partial shade. They did better than the sunchokes in the sun, because we had a drought. So, some shade can be good even for the most sun-loving plants, depending.
