Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged during the growing season. Reduce watering significantly when the plant goes dormant, allowing the soil to dry out between waterings.
Overwatering can lead to root rot, especially in cooler temperatures.
Deadhead spent flowers to encourage more blooms and maintain a tidy appearance. Trim back leggy growth if the plant becomes straggly.
Pruning can also be done after flowering to shape the plant and remove any dead or damaged foliage.
Propagate by division of tubers or by seeds. Divisions can be made in spring when new growth appears. Seeds can be sown in spring, but germination may be erratic and require specific conditions.
Cuttings can also be taken from stem sections.
Repot every 1-2 years in spring or early summer, or when the plant becomes pot-bound. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the current one to avoid excess moisture retention and promote healthy root development.
