Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged, especially during the active growing season. Allow the top inch of soil to dry out slightly between waterings.
Reduce watering in cooler months to prevent root rot.
Prune lightly after flowering to encourage bushier growth and prevent excessive seed set. Remove any dead or damaged stems throughout the growing season.
Pinch back the tips of young plants to promote a more compact form.
Propagate from seed sown in early spring, either directly outdoors after the last frost or indoors a few weeks prior. Seeds germinate best in warm, moist conditions.
Cuttings can also be taken from softwood in late spring or early summer.
Repot young plants annually in spring as needed, typically when roots begin to fill the pot. Mature plants can be repotted every 2-3 years.
Use a well-draining potting mix and a pot that is only slightly larger than the current one.
