Begonia Maculata Care: The Polka Dot Begonia

Begonia maculata (also called polka dot begonia or angel wing begonia) is one of the most striking houseplants you can grow. The leaves are olive green with bright silver polka dots on top and deep red undersides. The contrast is stunning.

Begonia maculata is not a beginner plant. It needs bright light, high humidity, and careful watering. But if you can meet its needs, it is unforgettable.

Quick Care Summary

  • Light: Bright, indirect light (some gentle direct sun okay)
  • Water: When top inch of soil is dry
  • Humidity: 50 to 70 percent (moderate to high)
  • Growth habit: Upright, cane-type begonia
  • Biggest challenge: High humidity and susceptible to powdery mildew

Light

Begonia maculata needs bright, indirect light with a few hours of gentle direct sun.

Best light:

  • East-facing window (morning sun is ideal)
  • South or west window with sheer curtain

Signs of too little light:

  • Leggy growth
  • Fewer polka dots
  • Slower growth

Signs of too much light:

  • Faded, washed-out leaves
  • Brown, scorched edges

Watering

Water when the top inch of soil is dry. Begonia maculata does not tolerate overwatering or underwatering well.

How to water:

  1. Check the top inch of soil
  2. If dry, water thoroughly until it drains
  3. Empty the saucer
  4. Avoid getting water on the leaves (can cause powdery mildew)

Typical schedule:

  • Spring and summer: Every 5 to 7 days
  • Fall and winter: Every 10 to 14 days

Humidity

Begonia maculata needs moderate to high humidity.

Ideal humidity: 50 to 70 percent.

How to increase humidity:

  • Use a humidifier (best option)
  • Group with other plants

Do not mist. Wet leaves encourage powdery mildew.

Signs of low humidity:

  • Brown, crispy leaf edges
  • Leaves curling

Soil and Pot

Use well-draining, airy soil.

Best soil:

  • 40% potting soil, 30% perlite, 20% orchid bark, 10% peat moss

Pot requirements:

  • Must have drainage holes
  • Not too large

Temperature

  • Temperature: 65 to 75 F
  • Avoid: Cold drafts, temperatures below 60 F

Fertilizer

  • Fertilize every 2 to 4 weeks in spring and summer
  • Use diluted liquid fertilizer (half strength)
  • Skip fertilizing in fall and winter

Pruning

Begonia maculata can get tall and leggy. Prune to control height and encourage bushier growth.

How to prune:

  1. Cut back tall stems
  2. Remove damaged or yellowing leaves
  3. You can propagate the cuttings

Propagating Begonia Maculata

Begonia maculata propagates easily from stem or leaf cuttings.

Stem cuttings:

  1. Cut a stem with 2 to 3 leaves
  2. Root in water or moist soil
  3. Roots develop in 2 to 4 weeks

Leaf cuttings:

  1. Cut a healthy leaf with stem
  2. Place in water or moist soil
  3. New growth develops in 4 to 6 weeks

Common Problems

Powdery mildew

White powdery coating on leaves. Caused by high humidity + poor air circulation or wet leaves.

Fix:

  • Increase air circulation (use a fan)
  • Avoid getting water on leaves
  • Remove affected leaves
  • Treat with neem oil or fungicide

Brown leaf edges

Low humidity or underwatering. Increase humidity and water more consistently.

Yellow leaves

Overwatering or natural aging. Check soil moisture and drainage.

Leggy growth

Not enough light. Move to a brighter spot and prune.

Pests

Begonia maculata can attract spider mites, aphids, and thrips. Inspect regularly.

Why Begonia Maculata Is Worth the Challenge

The polka dots and red undersides are stunning. When backlit, the leaves glow red. Begonia maculata also produces delicate white or pink flowers in summer.

If you can provide bright light and humidity, it is worth the effort.

What To Do Next

  • If you love spotted plants, try Hypoestes (polka dot plant) for an easier option
  • If Begonia maculata is too fussy, try Philodendron or Pothos instead
  • If your begonia has powdery mildew, increase air circulation and avoid misting
