Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist, especially during the growing season. Water deeply when the top inch of soil feels dry. Reduce watering in winter.
Prune lightly in spring to shape the plant and remove any dead or damaged stems. Pinch back young plants to encourage bushier growth. Deadheading spent flowers can prolong blooming.
Easily grown from seed sown directly outdoors after the last frost or started indoors 6-8 weeks prior. Cuttings can also be taken in summer.
If grown in a pot, repot annually in spring into a slightly larger container with fresh potting mix. Ensure good drainage to prevent root rot.
