Treatmentâś… Do:
Plant near ponds, shaded corners, or in large pots with rich moist soil.
Fertilize every 4–6 weeks during the growing season with organic compost or liquid fertilizer.
Divide clumps every 2–3 years to keep them vigorous.
In Addis’ dry season (October–May), water regularly as rain is absent.
❌ Don’t:
Don’t let soil dry out completely — it weakens flowering.
Don’t let it sit in stagnant water for long (causes root rot).
Don’t over-fertilize with nitrogen — it causes leafy growth but fewer flowers.
