Timing shifts with your zone — the Genie can pin down exact dates for you.
How to care for it
Plant bare-root or container stock in early spring or fall. Water only the first year — after that it thrives on neglect. Cut hard to keep it hedge-shaped and to harvest nitrogen-rich mulch.
Good companions
Excellent nurse plant for fruit trees and windbreak edges
Harvest
Snack on the young pea-like pods in early summer; chop branches for nutrient-rich mulch anytime.
