Water the plant once a week in the summer and spring, and once every two weeks in the winter and fall. You can tell when the Polka dot needs watering by the top half-inch, when it’s dry you can water it. Polka dot might like moisture and humidity but do not mist this plant.
Misting the Polka Dot Begonia can give life to fungal issues and root rot. An excellent method to water this Begonia is bottom watering. Place the plant into a tray or bowl filled with water and let it soak up the water until its soil is moist.
Keep Polka Dot Begonia in a spot with bright light with shadows casting over it for the bigger part of the day. If Begonia Maculata gets excessive light, the tips of the leaves will turn brown and fade in color.

Soil & Fertilizer
Soil pH levels should be between 6.1 and 7.5, so mildly acidic to neutral. The best soil for Polka dot would be soil that’s high in nutrients and well-aerated. To help create a porous form you can add equal parts of pumice, peat moss, and perlite.
Fertilize the plant every two to four weeks when the plant is actively growing aka in the summer and spring. Fertilize with a water-soluble, all-purpose fertilizer.
Do not feed the plant in the late fall and winter, as this is the plants resting period. Polka dot is sensitive to excessive fertilizer as it can damage the leaves.
Because the Polka dot Begonia is tropical, it flourishes best in warm and humid conditions. A relative humidity level of 45% and over is ideal. The best temperature is no lower than 59 °F ( 15 °C).
If the ideal climate is impossible to attain then you can also place the plant on a tray of moist pebbles. In the summer, the plant will do great outside in some shade. This plant can grow outdoors in the USDA Hardiness zones 10-11.
Repot the Polka Dot Begonia annually every spring. They love small ceramic pots, 1 – 1.5 inches (3 – 4 cm) in diameter larger than the root system. Always make sure the container you’re planting your Begonia has drainage holes.
Avoid repotting too often because the plant is root-bound. Replace the old pot with a new pot one size bigger. When potted into a container too broad they will struggle to grow and eventually wither away.
The prime time for propagating would be spring:
- With sharp shears or scissors cut off 10cm (4 inches) shoots without flowers below the leaf node
- Place the cutting in a glass of water
- Place into a warm and light spot
- The preferred temperature is 68 °F (20 °C)
- Change the water every 3 – 5 days.
- The formation of roots can take a couple of weeks or a couple of months.
- Once the roots have formed plant them into a pot with high-quality potting soil.
