Establishment
First 3-6 monthsYoung plant developing root system and establishing basic shape with emerging stems and early leaf growth
Keep soil consistently moist. Mulch around base. Water regularly first growing season. Protect from harsh winds.
Vegetative Growth
Months 6-12Plant develops full canopy with opposite, elongated green leaves. Stems become more woody and structured.
Prune lightly to encourage bushiness. Fertilize monthly with balanced fertilizer during spring and summer. Monitor for pests.
Flowering
May-July (6-8 weeks)Small, 5-petaled bright yellow flowers appear in terminal clusters (corymbs) at branch tips in late spring to early summer
Do not deadhead if you want fruit production. Maintain consistent moisture. Reduce nitrogen fertilizer to encourage more blooms.
Fruit Development
July-November (4-5 months)Flowers fade and berries develop, initially appearing red, gradually ripening to deep burgundy or black over weeks
Continue regular watering. Berries provide ornamental interest for months. Prune out any diseased growth.
Dormancy/Winter
November-March (4 months)In cold zones, foliage may drop or turn bronze-red. Berries persist on bare stems. Plant enters reduced growth phase.
Reduce watering in winter. No fertilization needed. Prune in late winter to shape or remove dead wood. Protect young plants from hard freezes.

Harvest Tips
Harvest cut branches with flower clusters in late spring to early summer for fresh arrangements.

Branches with berries can last 2-3 weeks in water. Harvest in morning when stems are hydrated.
