How to Care for Zonal Geranium

How should I handle sunlight?

Provide at least 6 hours of direct sunlight daily for optimal flowering. In scorching afternoon heat, partial shade is beneficial.

How should I handle soil and fertilizer?

Use well-draining potting mix. Feed with a balanced, water-soluble fertilizer every 2-4 weeks during the active growing season.

How should I handle pruning?

Deadhead spent flowers regularly to encourage continuous blooming. Prune back leggy stems in early spring to promote bushier growth.

How should I handle watering and moisture control?

Allow the potting soil to dry out thoroughly between watering sessions. When you do water, soak the soil deeply until water runs out of the drainage holes. Avoid overhead watering to reduce the risk of fungal diseases, and never let the plant sit in standing water to prevent root rot.

How to Propagate Zonal Geranium

How to propagate Zonal Geranium by seed?

Sow seeds indoors in early spring at a temperature of 20-24 °C under light.

How to propagate Zonal Geranium by cutting?

Take stem cuttings of about 10 to 15 centimeters from healthy, non-flowering shoots during spring or late summer. Remove the lower leaves, dip the cut end in rooting hormone, and insert into a well-draining propagation medium. Keep the soil lightly moist and place the container in bright, indirect light until roots develop thoroughly.
