Group:
Is it especially advisable to plant nitrogen-fixing shrubs (i.e. buffaloberry - Shepherdia; guomi - Elaeagnus; sea-buckthorn - Hippophae; etc.) beneath fruit/nut trees such persimmon and hickory? If you're soil is already moderately fertile, will this help?
I like plant native grasses/forbs underneath my trees and I'm afraid that - native choices or not - nitrogen-fixing plants will encourage alien invasive weeds to succeed over the native species.
Thanks,
