Iron Cross Begonia Care: Dramatic Patterned Leaves

Unmistakable Foliage

Begonia masoniana has bright green puckered leaves with a reddish-brown iron-cross center. Pinkish-white flowers spring/summer—insignificant; pinch buds for better leaves.

Care Essentials

• Light: Bright indirect. Thrives under fluorescents.
• Water: Thoroughly, top inch dry between. Rhizomes store water. Avoid wet leaves (spot/mildew).
• Humidity: Moderate to high. Humidifier/pebble tray. Good air circulation (no vents).
• Temp: 65–75°F. No <50°F.
• Soil: African violet mix.
• Fertilizer: Monthly year-round, 10-10-5 half-strength. On moist soil only. Skip dormant periods.

Dormancy

May collapse/shrivel in winter. Stop watering. Cover with plastic/cloche, keep ~60°F 6–8 weeks. New leaves emerge.

Maintenance

• Repot spring, 1 size up. Small pot + drainage. Don’t pack soil tight—begonias like air at roots.
• Watch for powdery mildew (poor air flow + high humidity). Remove affected leaves; fungicide if needed.

Propagation

3-inch stem cuttings with leaves early summer in moist sterile mix. Cover with plastic/cloche until new leaves form.

Distinctive, dormant, delightful.
