☀️

Sunlight Full sun to partial shade; thrives in open, disturbed sites and tolerates nutrient-poor soils

💧

Watering Water regularly during extended dry spells; drought-tolerant once established and mature

🌡️

🔍

Leaf: Alternate, lanceolate to oblong leaves with serrated margins; upper leaves are smaller and clasping the stem

🛠️

Watering

Keep soil evenly moist during active vegetative growth and flowering

Fertilization

No regular fertilization required. Diluted compost tea can be applied once monthly if growing in severely nutrient-poor soil

Composted banana peel tea：Steep fully composted banana peels in water for 3 days; dilute 1:20 with water for root drenching to avoid nutrient burn

Pruning

Deadhead spent flower clusters to prevent unwanted self-seeding in managed garden spaces
Cut back entire plant to ground level after seed dispersal to tidy the growing area
Remove damaged or yellowing lower leaves to improve airflow and reduce pest habitat
