Begonia Maculata is a low maintenance houseplant known for its polka dot foliage. This was one of my very first houseplants and its also been one of my easiest.

Here are the main things you need to know to properly care for Begonia Maculata.

  1. Water. Thoroughly water your Begonia Maculata when the top two inches of soil are dry. Check the soil moisture by placing your finger in the soil a knuckle deep or use a moisture meter.
  2. Light. Place Begonia Maculata in a spot getting bright indirect sunlight. This would be near a south, east, or west facing window. You can also place this plant under plant grow lights.
  3. Fertilizer. Feed your Begonia Maculata during the active growing season (typically March-October). Good fertilizer options include Dyna-Gro Grow or plant food like Liqui-Dirt.
  4. Humidity. Begonia Maculata does not need high humidity. My plant lives in regular household humidity of about 20%.

Here’s what you need to know to make sure your Begonia Maculata thrives in its new home.


Place your Begonia Maculata in a spot getting bright indirect sunlight. This would be near a south, east, or west facing window.

If placing your plant near a south facing window, make sure to place a sheer curtain between your plant and the sunlight. You never want your plant to get direct sunlight because direct sunlight burns the plants foliage.

North facing windows get the least amount of sunlight and also has the weakest sunlight. Begonia Maculata can survive in this area, but the plants growth may be slower than a plant sitting in a south facing window.

You can also place this plant under plant grow lights. I use T5 Barrina plant grow lights and recommend them. I have these lights set on timers so I never have to turn them on or off. These grow lights are connected to an app so I can control them through my phone.


Water your Begonia Maculata when the top two inches of soil are dry.

Check the plants soil by placing your index finger a knuckle deep. If the water is dry, it’s time to give your plant a thorough watering.

To make things easier and more convenient for me, I feed my plants fertilizer and pest killer every time I water my plants. I mix fertilizer and pest killer in the plants drinking water so the plants get this every time.


Begonia Maculata thrive in well-draining soil.

This kind of soil helps the roots get the oxygen and air flow that it needs. Well-draining, chunky soil is a must especially for people who tend to be overwaterers.

If you’re a DIY-er, an easy well-draining soil recipe calls for 50% coco coir, 25% orchid bark, and 25% perlite.

You can also buy houseplant soil that is already mixed and ready for you. A popular brand is Fox Farm Ocean Forest organic potting soil and I often use this for many of my houseplants.


Begonia Maculata live in temperatures between 55°F and 85°F. These plants like to stay on the warmer side.


Fertilizing your houseplants is important because it keeps the plants thriving and happy in your home. Out in the elements in nature, your plant naturally gets the fertilizer and nutrients it needs, but this isn’t the case in your home.

There are many different types of fertilizer to choose from and you can go the all natural route or synthetic route. If using a synthetic fertilizer, you need to dilute the recipe in half because synthetic fertilizer is quite strong and can hurt your plant.

I personally use Dyna-Gro Grow and mix it into my plants drinking water. I fertilize every watering because it keeps things simple for me and I like to think that it helps keep my plants happy.


Begonia Maculata thrive in regular household humidity. My house sits at about 20% humidity and that’s all my plant needs to grow.

If you want to increase the humidity around your plant, here are my best tips.

  • Place your plant on a pebble tray of water
  • Place a humidifier near your houseplants and run it daily
  • Group high humidity plants together which will create a microclimate of humidity
  • Use an IKEA cabinet as a DIY greenhouse cabinet


The easiest way to propagate Begonia Maculata is by cutting the stem with at least one leaf.

With clean sheers, make a cutting and place the stem in water. These are crazy fast growers and you should see a ton of roots in a few weeks.

Place this cutting in a spot getting decent sunlight (about any window will do). In about three weeks you should notice roots growing. Once the roots are at least three inches long, you can transfer the cutting into your preferred substrate.

Here is a picture of my Begonia Maculata. I would cut where my fingers are and place this stem cutting in water.
