Begonia Care Guide

Begonia Care Guide

Begonias are versatile and vibrant plants that come in hundreds of varieties, from waxy-leafed wax begonias to dramatic rex begonias with colorful foliage. They're rewarding to grow indoors and out.

Light

Most begonias prefer bright, indirect light. Rex begonias tolerate lower light, while cane and wax begonias appreciate more brightness. Avoid harsh direct afternoon sun.

Watering

Water when the top inch of soil feels dry. Begonias are susceptible to root rot — never let them sit in standing water. Water at the base to avoid wetting the leaves, which can cause mildew.

Humidity

Begonias prefer moderate humidity (40–60%). Avoid misting directly on leaves. Instead, use a pebble tray or humidifier nearby.

Temperature

Keep temperatures between 60–75°F (15–24°C). Begonias are frost-sensitive — bring them indoors before temperatures drop below 50°F.

Soil & Potting

Use a light, well-draining potting mix. A blend of potting soil and perlite works well. Choose pots with drainage holes.

Fertilizing

Feed every 2–4 weeks during the growing season with a balanced or bloom-boosting fertilizer. Reduce feeding in fall and winter.

Common Issues

• Powdery mildew: Caused by poor air circulation or wet leaves — improve airflow and avoid overhead watering.
• Leggy growth: Move to a brighter location and pinch back stems to encourage bushiness.
• Yellow leaves: Usually overwatering or poor drainage.

Propagation

Begonias are easy to propagate from stem cuttings or leaf cuttings placed in moist soil or water. Roots typically develop within 2–4 weeks.
