Watering, pruning, propagation, and repotting details from plant data
Water regularly when the top inch of soil feels dry. Avoid waterlogging, as this can lead to root rot. In hotter, drier conditions, increase watering frequency.
Ensure good drainage to prevent excess moisture build-up, especially during cooler months.
Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Cut back leggy stems in mid-summer to promote bushier growth and a second flush of flowers.
Light pruning in early spring can shape the plant.
Propagate by seed sown in spring or autumn, or by cuttings taken in late spring or early summer. Seeds can be sown in trays and kept moist in a cool, sheltered spot. Cuttings should be rooted in well-draining compost.
Repot young plants annually in spring to refresh the soil and provide more space for root growth. Mature plants can be repotted every 2-3 years or when root-bound. Use a good quality, free-draining potting mix.
