Begonia Maculata Care: How to Help the Polka Dot Begonia Thrive

With its silver-spotted leaves and crimson undersides, the Begonia maculata, often called the Polka Dot Begonia, is the definition of botanical drama. Native to the tropical forests of Brazil, this striking houseplant brings a sense of style to your indoor jungle. But keeping those speckled leaves lush takes a little know-how. Here’s how to care for your Begonia maculata so it thrives year-round.

1. Light: Bright, Filtered, and Gentle

The Begonia maculata loves bright, indirect light. Too much direct sun can scorch its delicate leaves, and low light dulls their signature spots. Place it near an east- or north-facing window, or a few feet back from a bright south-facing window with sheer curtains. You’ll know it’s happy when new leaves unfurl in that olive-green shimmer.

If your plant’s leaves turn pale or drop, that’s a sign it’s not getting enough light. A small grow light can work wonders in darker rooms.

2. Water: Consistency Over Frequency

Begonias prefer evenly moist soil—but never soggy roots. Water when the top inch of soil feels dry, letting excess water drain completely. Over-watering can lead to root rot and leaf yellowing. If the air in your home is dry, try grouping your Begonia with other tropicals or using a pebble tray for gentle humidity.

3. Soil & Potting: Airy and Well-Draining

The polka-dot begonia loves breathable soil. A mix of peat moss, perlite, and a bit of orchid bark creates the perfect airy texture. Repot every year or two in spring to refresh nutrients, but don’t move up more than one pot size. Begonias prefer to stay slightly snug.

4. Temperature & Humidity: Keep It Tropical

Aim for temperatures between 65–80°F and humidity above 45–50%. Sudden drafts or cold windows can stress the plant and cause leaf drop. In winter, keep it away from vents or doors and mist lightly in the morning.

5. Feeding for Growth and Blooms

From spring through early fall, feed monthly with a balanced liquid fertilizer diluted to half strength. Fertilizer helps fuel both foliage and flower production. When conditions are right, you’ll be rewarded with clusters of small white blooms that arch gracefully above the leaves.

6. Pruning & Propagation

Trim leggy stems to maintain shape and encourage branching. Those cuttings can easily root in water, just place them in a clear glass jar in bright, indirect light, and soon you’ll have baby begonias to share or pot up.
