💧 How to Water
Water deeply but infrequently. Soak the root zone at planting and while the plant establishes, then switch to occasional deep watering only during extended dry, hot spells — soggy soil invites root rot.
☀️ Lighting
Plant in full sun with at least 6 hours of direct light daily. Too much shade causes leggy growth and fewer flowers.
