Caring for germinated Plumeria seedlings involves providing them with the right conditions to thrive. Place the seedlings in a warm, well-lit location with indirect sunlight. Ensure the growing medium remains consistently moist but not waterlogged to support healthy root development. As the seedlings grow, they will develop true leaves, at which point you can start using a balanced liquid fertilizer diluted to half strength to provide essential nutrients. Avoid exposing the young seedlings to extreme temperatures, direct sunlight, or strong winds, as they are still delicate at this stage. Gradually acclimate the seedlings to outdoor conditions before transplanting them into their final growing location.
