Growth Stages

1

Establishment

Year 1

Young shrub focuses on root development and stem growth. Minimal flowering in year one.

Water regularly to establish deep roots. Mulch around base. Prune to establish desired shape.

2

Flowering

2-3 weeks in early spring

Upright stems produce abundant fragrant white flowers in clusters during early spring before leaf emergence.

Minimal intervention needed. Flowers appear on previous year's growth; avoid pruning during flowering.

3

Fruit Set & Development

4-6 weeks

Small green berries develop following flower pollination, gradually enlarging through late spring and early summer.

Ensure adequate water during dry periods. Thin crowded berries if desired for larger individual fruits.

4

Ripening

2-4 weeks

Berries transition from green to red to dark purple-black as sugars concentrate. Ripe berries are soft and sweet.

Protect from birds with netting if harvesting for human use. Monitor for readiness.

5

Dormancy

November-March

Shrub loses leaves in fall and enters winter dormancy. Buds form on stems for next spring's flowers.

No active care needed. Plant is extremely cold-hardy. Prune during late winter if needed.

Harvest Tips

Berries ripen over several weeks in early to mid-summer (June-July depending on location). Harvest when fully dark purple-black and soft to touch. Berries do not ripen uniformly, so multiple harvests may be needed. Shake branches gently over a cloth to collect berries, or handpick. Ripe berries are sweet with mild nutty flavor. Store in refrigerator for up to 2 weeks, or freeze for extended storage.
