How to Grow Silver Buffaloberry
Shepherdia argentea
Silver Buffaloberry is a tough, drought-tolerant native shrub producing tart red berries excellent for jam. Plant in full sun in well-drained soil — it thrives on neglect and fixes its own nitrogen. You need both a male and female plant for fruiting. Extremely cold-hardy. Prune lightly in late winter to maintain shape. Berries ripen in late summer and are best harvested by spreading a sheet and shaking the branches.
Yearly Lifecycle
Care Essentials
Rarely needs feeding — fixes its own nitrogen. Top-dress with compost in spring if growth is poor.
Watch For
- Aphids on new growth
- Leaf spot diseases in humid conditions
- Scale insects
Care Requirements
Light
Full sun
Needs at least 6 hours of direct sun daily. Tolerates partial shade but fruiting is much reduced. Performs best in open, exposed positions.
Watering
Low — drought-tolerant once established
Water regularly in the first year to establish. Once established, extremely drought-tolerant and rarely needs supplemental watering. Avoid waterlogged soils.
Fertilizing
Rarely needed — nitrogen-fixing shrub
Silver Buffaloberry fixes its own nitrogen through root nodules. Top-dress with compost in spring only if growth is visibly poor. Avoid high-nitrogen feeds.
Pruning
Light shaping in late winter only
Prune lightly in late winter before bud break to maintain shape and remove dead or crossing branches. Avoid hard pruning as it reduces fruiting wood.
Spacing
2.5-3m apart; plant both sexes
Plant male and female shrubs within 15m of each other for pollination. Space individual plants 2.5-3m apart. Allow room for mature spread of up to 3.5m.
Support
None needed
Strong-stemmed and self-supporting once established. No staking or support required.
