Germination
:
Seeds germinate slowly (can take 6–12 weeks); propagation is typically done through cuttings or layering
P.H. Level
:
Neutral to slightly alkaline (6.5–7.5); adaptable to various pH levels
Water/Irrigation
:
Water newly planted shrubs once or twice a week; water as needed during hot, dry periods
Fertilization
:
Apply a balanced fertilizer with an NPK ratio of about 10-10-10 in early spring
Habit
:
Upright to arching growth habit; forms a fountain-like shape
Propagation
:
Softwood cuttings, layering, division
Final Plant Height
:
6–10 ft
Spread
:
8–12 ft
Flowers
:
Bright yellow, four-petaled blooms along bare stems before leaves emerge

Minimal disease problems; possible anthracnose, leaf spot, yellow leaves, or stem cankers under unfavorable conditions
