For planting corynaea, prefer well-draining, fertile soil with adequate organic matter. Choose a location with partial shade, as intense direct sunlight may be detrimental. Regular, moderate watering is essential to keep the soil consistently moist but not waterlogged. To plant, dig a hole twice as wide and the same depth as the root ball. Gently place the corynaea in the hole, backfill with soil, and water thoroughly. Mulch can help retain moisture. Always consider individual species requirements, as corynaea can vary in specific needs.
