When to plant Drumstick Allium
Drumstick Allium is a fall-planted bulb: get it in the ground 6 to 8 weeks before the ground freezes, typically September or October across zones 4 to 8. It pays you back the following June to July.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in September.
