Light Requirements
Most Begonias thrive in bright, indirect light. They need enough light to produce their stunning foliage patterns and flowers, but direct sun scorches their delicate leaves.
- Bright indirect — Ideal for all types. Near east- or north-facing windows works well.
- Medium light — Acceptable for foliage types. Flowering may decrease.
- Direct sun — Avoid. Causes leaf scorch and bleached spots.
- Low light — Most Begonias struggle. Colors fade, growth stalls, and flowering stops.
Watering
Begonias prefer to stay lightly moist but never waterlogged. Their stems are succulent-like and store water, making them somewhat drought-tolerant but very susceptible to root rot from overwatering.
- Water when the top inch of soil feels dry
- Water at the base — avoid getting water on leaves (it causes powdery mildew and leaf spots)
- Spring/Summer: Every 5–7 days
- Fall/Winter: Every 7–14 days
Humidity
Begonias appreciate 50–70% humidity. While they tolerate average indoor conditions, higher humidity produces lush, vibrant foliage. Use a humidifier or pebble tray — but avoid misting, as wet leaves invite disease.
Temperature
Begonias prefer 60–75°F (16–24°C). They're more cold-sensitive than many houseplants — avoid temperatures below 55°F and keep away from drafts.
Soil
Use a light, airy, well-draining mix:
- 2 parts peat moss or coco coir
- 1 part perlite
- 1 part fine orchid bark
Begonias prefer slightly acidic soil (pH 5.5–6.5). Good drainage is critical — their stems and roots rot quickly in heavy, wet soil.
Fertilizing
- Feed every 2–4 weeks during spring/summer with balanced liquid fertilizer at half strength
- Stop in fall/winter
- For Angel Wing Begonias, a bloom-boosting fertilizer (higher phosphorus) encourages flowering
Propagation
Begonias propagate readily from stem cuttings:
- Cut a 4–6 inch stem section with at least one node
- Remove lower leaves
- Place in water or moist perlite
- Roots develop in 2–4 weeks
- Transfer to soil once roots are 1–2 inches long
Rex Begonias can also be propagated from leaf cuttings — lay a leaf on moist soil with small cuts along the veins, and new plantlets emerge at each cut.

Common Problems
Powdery Mildew
White powdery coating on leaves. Caused by poor air circulation and wet foliage. Improve ventilation, avoid misting, and treat with fungicide if needed.
Leaf Drop
Usually caused by overwatering, cold drafts, or sudden changes in environment. Check soil moisture and relocate if near a vent or drafty window.
Leggy Growth
Insufficient light. Move to a brighter location and prune back leggy stems — Begonias respond well to pruning and branch at the cut points.
Yellowing Leaves
Overwatering or poor drainage. Check roots for rot, improve drainage, and adjust watering frequency.
Frequently Asked Questions
Are Begonias easy to grow?
Most Begonias are easy to moderate. Angel Wing varieties are among the easiest — they're forgiving of occasional care mistakes and reward you with stunning foliage and flowers. Rex Begonias are slightly more demanding about humidity.
Do Begonias need direct sunlight?
No. Begonias prefer bright indirect light. Direct sun scorches their leaves. A spot near an east-facing window is ideal.
How do I get my Begonia to flower?
Provide bright indirect light, feed with a phosphorus-rich fertilizer in spring, and keep the plant slightly pot-bound. Angel Wing Begonias are the most reliable indoor bloomers.
Are Begonias safe for pets?
Begonias are toxic to cats and dogs, especially the roots and tubers. Keep them on high shelves or choose pet-safe alternatives.
How long do Begonias live?
With proper care, Begonias can live for many years — cane-type Begonias (including Angel Wings) can thrive for decades. They respond well to pruning, which keeps them compact and vigorous.
