Ideal Growing Conditions
Sunlight
| Type | Requirement |

Soil
Begonias prefer loose, breathable, and well-drained soil.
Recommended Mix
- 40% coco peat or peat moss
- 30% perlite or sand
- 30% compost or leaf mold
Soil should stay moist but never soggy.
Watering
Begonias hate overwatering. Follow this:
- Water when top 1–2 inches of soil is dry
- Avoid wetting leaves (reduces fungal disease risk)
- Ensure pot has drainage holes
Summer: Water 2-3 times/week
Winter: Once per week or less
Humidity & Temperature
| Condition | Ideal Range |
|---|---|
| Temperature | 18°C – 28°C (65°F – 82°F) |
| Humidity | 50% – 70% |
They dislike cold drafts and temperatures below 10°C (50°F).
Fertilization
Feed begonias every 2–3 weeks during growing season.
Best fertilizer:
- Balanced liquid fertilizer (10-10-10 or 20-20-20)
- Dilute to half strength
Stop fertilizing during winter dormancy.
Potting & Repotting
Begonias prefer slightly root-bound pots.
Repot every 1–2 years or when:
- Roots overflow pot
- Soil drains poorly
- Growth slows down
Use clay or ceramic breathable pots.
