Light

Most of the new growers think that this plant is a low-light plant. But in reality, it needs few hours of direct sunlight. No doubt it cannot tolerate long hours of direct sunlight. But a minimum of 3 hours of direct sun rays is necessary for better health.

Now the question is which part of the day is best to put it on the sunny window. Morning sunlight is best for houseplants. Because in the morning time sun emits low intense light waves. These light waves are warm which is a good thing.

Because warm sun rays do not harm the plant in fact these sun rays make your plants strong.

So, if you have begonia plants at home give them 3 hours of morning sunlight. Otherwise, your plants will grow weak and lanky. They easily get affected by plant diseases and do not produce flowers.

Low flowers are also linked with a low light environment.

Outdoor growing begonias need shade from 11 Am to 4 Pm. Locate a place in your garden where they can get indirect bright light. Or grow them with other tall plants.

If your plant is still getting sunlight between 11 to 4. Then take a cotton cloth and make a shed off it over the plant in some way. Plant two bamboo poles on the sides of the plant and tie cloth to block light.

Water

Watering polka dot begonias is the tricky part. Because this plant needs moist soil to grow but do not like frequent watering. So, before watering the plant you need to check the soil.

Temperature

The begonia maculata is a tropical plant so it cannot survive in cold weather. Indoor temperature is good for growing begonia maculata. Because even in winter we set our thermostats between 15 degrees C to 22 Degrees C. This is the perfect temperature range for houseplants.

The problem comes with outdoor growing begonia plants. They die when the temperature drops below 10 degrees C.

Do not put the indoor growing plant near the heating vents. Because the continuous flow of hot air keeps the plant and soil dry. Dryness is a deadly condition for tropical plants.

Humidity

Remember that you need to fertilize the plant only in its active growing stage (spring and summer). Winter is the rest time for the plants they do not grow in this time. So do not waste the fertilizer by giving them in winters.

Soil

The soil should be well-draining soil. No doubt plant likes to grow in moist soil but they do not like wet or soggy soil. If your gardening budget allows you then you can buy specially made potting soil for houseplants. If the low budget is a problem then you can make potting soil at home.
