Care guide for Macfarlane's Four O'clock

Watering, pruning, propagation, and repotting details from plant data

Water

Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in fall and winter.

Ensure good drainage to prevent root rot, as this plant is sensitive to overwatering, especially in cooler temperatures.

Pruning

Prune in late winter or early spring before new growth emerges. Remove dead, damaged, or crossing stems. Light pruning can also be done after flowering to shape the plant and encourage bushier growth.

Deadheading spent flowers can prolong blooming.

Propagation

Easily propagated from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds may require stratification. Cuttings should be rooted in well-draining potting mix in a warm location.

Repotting

Repot established plants every 2-3 years in spring, moving to a slightly larger container. Use a well-draining potting mix. This helps to refresh the soil and provide space for root growth, ensuring continued vigor.
