For gronovia, ensure well-draining soil enriched with organic matter, providing a balance of moisture retention and aeration. Position gronovia in bright, indirect light, protecting from harsh midday sun. Water to keep the soil consistently moist, but not waterlogged. Plant in spring or early summer. Dig holes larger than root balls, place gronovia gently, backfill, and tamp down soil without compacting. Apply mulch to retain soil moisture. Specific requirements may vary, so consider each species' unique needs for optimal growth.
