Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings, especially during warmer months.
Reduce watering in winter to prevent root rot, but do not let the soil become completely dry.
Deadhead spent flowers regularly to encourage more blooms and prevent self-seeding.
In autumn, cut back the plant to the ground after it has finished flowering to maintain a tidy appearance and prepare it for winter dormancy. Remove any dead or diseased foliage promptly.
Propagate by seeds sown in spring or autumn, either directly outdoors or in a seed tray. Seeds germinate best with light. Alternatively, divide established clumps in spring or autumn.
Ensure divisions have healthy roots and at least one or two shoots.
Youngia thunbergiana is not typically a potted plant and is best grown in the ground. If grown in a container, repot in spring when the plant shows signs of outgrowing its current pot.
Use a well-draining potting mix and a pot that allows for adequate root spread.
