Care essentials
Light
Crown of Thorns demands full sun — at least 6 hours of direct sun daily — to bloom reliably year-round. In NE Florida, place it in the sunniest spot in the landscape or on a south-facing patio; poor flowering is almost always caused by insufficient light.
Water
Crown of Thorns is extremely drought tolerant; water deeply but infrequently, allowing the soil to dry out completely between waterings. In NE Florida, established plants in the ground rarely need supplemental irrigation except during extended droughts. Overwatering is the most common cause of decline — never let roots sit in wet soil.
Soil & Fertilizer
Plant in very well-drained, sandy or gravelly soil; heavy clay or consistently moist soil will cause root rot. Fertilize once or twice a year with a balanced slow-release fertilizer; minimal nutrition is needed. Crown of Thorns is reliably hardy outdoors in zone 9b, though rare hard freezes may cause tip damage — plants recover quickly.
