The polka dot begonia, also known as begonia maculata, is an incredibly popular houseplant thanks to its beautiful spotted foliage. With proper care indoors, this begonia can thrive for years in any home. Here is a complete guide to caring for polka dot begonia plants indoors.
Light Requirements
Polka dot begonias need bright indirect light to maintain their vibrant leaf coloration and distinctive spots. Direct sunlight will scorch the leaves. An east or north facing window is ideal providing plenty of gentle light. If your begonia isn’t getting enough light, the leaves may fade or turn solid green.
Watering
These begonias like moist soil but hate sitting in water. Only water when the top inch of soil is dry. Water thoroughly until it drains from the bottom, then empty the drainage tray. Allow all excess water to drain away before returning the pot. Water less often in winter.
Soil
Use a rich, well-draining potting mix. Amendments like perlite, vermiculite or sand can be added to improve drainage. Never allow water to stand in the saucer or plant roots may rot.
Temperature & Humidity
Polka dot begonias thrive in average room temperature between 65-85°F and 45% humidity. Keep away from cold drafts. Increase humidity by grouping plants together or using a pebble tray.
Fertilizer
Feed monthly with a balanced liquid fertilizer during spring and summer. Discontinue fertilizing over winter when growth slows.
Potting
Choose a pot with drainage holes using a porous material like terra-cotta. Repot in spring only when roots fill the pot. Go up just one size to avoid stressing the plant.
Pruning & Grooming
Prune leggy stems back to an outward facing node to encourage full, bushy growth. Wipe leaves regularly with a damp cloth to prevent dust buildup and increase light absorption. Remove spent flowers and dying leaves.
Propagation
Take 3-4 inch stem cuttings in spring or summer. Remove lower leaves and place in water or moist potting mix. New roots will sprout in a few weeks. Transplant the rooted cuttings into small pots.
Troubleshooting Common Issues
-
Leaf spots may indicate a fungal disease. Improve air circulation and avoid wetting leaves.
-
Leggy growth means insufficient light. Move to a brighter location.
-
Crispy brown leaves or edges indicate low humidity. Mist leaves or use a pebble tray.
-
Few flowers can be caused by insufficient light or pruning. Allow plant to become rootbound.
With the right care, polka dot begonias will reward you with their uniquely patterned foliage for years to come. Provide bright indirect light, humidity, and well-draining soil and this gorgeous plant will flourish indoors.

FAQ
Where is the best place to put a Polka Dot Begonia?
Light and position
The Polka Dot Begonia is quite relaxed when it comes to its sunlight requirements. It prefers to live in bright, indirect sunlight, but it’s also happy to live in low light. This means it’s the ideal botanical for homes and offices that don’t get too much natural sun.
How much light does a Polka Dot Begonia need?
Spotted Begonia plants prefer bright, indirect light. They can tolerate some direct sunlight, but too much can cause their leaves to burn. An east-facing window that receives filtered sunlight is an excellent spot for these plants. If you don’t have access to a window with enough light, you can use artificial lighting.
Should I mist my spotted Begonia?
Begonias are prone to powdery mildew that can occur if their leaves are kept wet, so avoid getting the leaves wet during watering and do not mist the plant.
