Begonia Care Guide
Begonia Care Guide
Begonias combine dramatic foliage with compact growth, but different groups vary in their exact needs. Rex and foliage begonias generally prefer bright filtered light, an airy mix, and consistent moisture without soggy roots.
Quick answer: Keep foliage begonias in bright indirect light, water after the surface begins to dry, and provide airflow around the leaves.
Begonia care at a glance
- Light: Bright indirect light supports strong color and compact growth. East-facing light is often ideal. Avoid intense midday sun, which can bleach or scorch textured leaves.
- Water: Check the mix before watering. Water when the top inch is slightly dry, soak the mix evenly, and drain the saucer. Water the soil rather than keeping leaves constantly wet.
- Soil and repotting: Use a light mix that holds some moisture while draining quickly. A quality indoor mix amended with perlite and fine orchid bark works well. Begonias often prefer being slightly snug rather than overpotted.
- Growth and maintenance: Warm household temperatures and moderate humidity support steady growth. Provide airflow, remove damaged leaves cleanly, and fertilize lightly during active growth.

Growth and routine care
Warm household temperatures and moderate humidity support steady growth. Provide airflow, remove damaged leaves cleanly, and fertilize lightly during active growth.
Common problems
- Crispy leaf edges: Often linked to low humidity, drought, or mineral buildup.
- Mushy stems or roots: Usually indicates excess moisture or poor drainage.
- Pale leaves: May indicate too much direct light or insufficient nutrition.
- Powdery patches: Improve airflow and avoid leaving foliage wet for long periods.

Frequently asked questions
Do begonias need high humidity?
They appreciate moderate humidity, but airflow is just as important. Avoid sealing wet foliage in stagnant air.
Should I mist begonia leaves?
Direct misting is usually unnecessary and can leave foliage wet. A room humidifier is more consistent.
When should I repot a begonia?
Repot when roots fill the container or the mix stays compacted, usually during active growth.
