Plant the Tahitian Treasure Rose in a location with full sun exposure. Ensure the soil is well-draining and rich in organic matter. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize with a balanced rose fertilizer every 4-6 weeks during the growing season. Prune in late winter or early spring to remove dead or weak stems and encourage new growth. Protect from pests and diseases by monitoring regularly and applying appropriate treatments as needed.
