Types of Begonias

Before planting, it helps to understand the three main types of begonias:

1. Fibrous Begonias (Wax Begonias):
   These are compact and ideal for borders, containers, or hanging baskets. They thrive in both sun and shade.

2. Tuberous Begonias:
   Known for their large, showy flowers, these begonias are perfect for hanging baskets or shaded patios. They grow from tubers that can be stored over winter.

3. Rhizomatous Begonias (including Rex Begonias):
   Grown mostly for their striking, patterned leaves, these begonias prefer bright, indirect light and make stunning indoor plants.

Light and Temperature

Begonias love bright, indirect light.

• Outdoors: Morning sun with afternoon shade is ideal. Too much direct sunlight can scorch their leaves.

• Indoors: Place them near a bright window, but out of harsh sunlight.

They thrive in temperatures between 60–75°F (15–24°C) and dislike sudden cold or drafts.

Watering and Humidity

Begonias prefer evenly moist but not soggy soil.

• Water when the top inch of soil feels dry.

• Avoid getting water on the leaves, which can cause spotting or mildew.

• They love humidity — mist them lightly or place a tray of water with pebbles nearby, especially indoors.

Soil and Fertilizer

Use a well-draining potting mix, ideally with peat, perlite, or compost. Begonias hate sitting in waterlogged soil.
Feed them with a balanced liquid fertilizer every 2–4 weeks during the growing season (spring through early fall). Cut back feeding in winter when growth slows.

Pruning and Maintenance

Regularly pinch back leggy stems to encourage bushier growth.
Remove any yellowing leaves or spent flowers to keep the plant healthy and tidy.

For tuberous begonias, allow the plant to die back naturally in fall. Then, dig up the tubers, let them dry, and store them in a cool, dark place until spring.

Common Pests and Problems

Begonias are relatively trouble-free, but keep an eye out for:

• Powdery mildew (caused by poor air circulation)

• Aphids and spider mites (which can be controlled with insecticidal soap)

• Root rot (a result of overwatering)

Propagation Tips

Begonias are easy to propagate! Try:

• Stem cuttings: Place a 4-inch cutting in water or moist soil until roots form.

• Leaf cuttings: Some varieties, like Rex begonias, can even grow new plants from leaf sections.
