Sunlight requirements
The Begonia Maculata can be exposed to two different types of sunlight exposure: bright, indirect sunlight, but also lower light situations. This makes it a perfect plant for all of those areas where you'd love to have a plant, but they all require more sunlight. Don't keep it in a space where it doesn't get any sunlight, it still needs some sunlight. Also, make sure to keep the Begonia Maculata out of direct sunlight in the afternoon. When your Begonia Maculata is exposed to this sunlight for too long, its beautiful leaves can get sunburns and dry out.
Watering your Begonia Maculata
A Begonia Maculata is a plant that loves to be in moist soil. This means you should water it regularly. Depending on the season, this could be once every 4 days in the summer and every week to two weeks in the winter. You can find out of you need to water your Begonia Maculata by touching the soil with your fingers and determine if it's still moist of if it's dry. If it's dry it's time to water your Polkadot plant. It doesn't like to be dry for too long, so make sure to check regularly.
If the soil is still moist when you check it, wait another day or two and check again. This helps to prevent overwatering this plant. The Begonia Maculata roots are thin which means it's quite sensitive to overwatering. So be sure to check the moisture levels of the soil before watering your plant.
The best soil for your Begonia Maculata
Begonia Maculata plants like to be in moist soil, so you should find a soil mix that retains water quite well. A palm soil mix is mix that retains water quite well, but at the same time, it doesn't compact after watering your plant a few times. The palm soil mix is the way to go for a Begonia Maculata.
Fertilizing your Begonia Maculata
The Begonia Maculata is a flowering plant, which means it requires fertilizer every once in a while to have enough energy to be able to keep growing. A good rule of thumb is to add liquid fertilizer to the water every other time you water the plant. Ideally, this would mean the Begonia gets fertilized every 2 weeks. However, only fertilize your Begonia during its growing season (spring and summer). During the dormancy period, autumn (fall) and winter, the plant shouldn't be fertilized, because this is when it needs to recover from the growing season and it needs to rest and prepare for the coming growing season.
Flowers on your Begonia Maculata
As we've mentioned in the last section, the Begonia Maculata is a flowering houseplant. Besides having striking and unusual leaves, it also grows flowers if it's taken care of well and has spare nutrients to be able to grow flowers. If you use fertilizer as described in the last section, you will have flowers during the growing season.
Like any flowers, they die after a short time. However, this doesn't mean the flowers won't come back. If you prune the flowers when they've bloomed, you might be able to help the plant grow flowers and bloom multiple times in a growing season.
If you don't want to grow any flowers, you won't have to fertilize your Begonia Maculata as often. You can stick to using liquid fertilizer once per month.
What are some common pests and diseases that affect Begonia Maculatas?
Begonia maculata, like any other plant, can be prone to pests and diseases. It's important to regularly check your plant for any signs of infestation or illness to address the issue as early as possible.
The most common pests that affect Begonia maculata are spider mites, mealybugs, and scale insects. Spider mites are tiny pests that can create webbing on the leaves and cause yellowing and wilting. Mealybugs are small, white, fluffy insects that feed on the sap of the plant and can cause stunted growth and yellowing leaves. Scale insects are small, oval-shaped insects that feed on the sap of the plant and can cause yellowing and dropping leaves.
To get rid of these pests, it's important to regularly inspect your plant and remove any affected leaves or pests by wiping them off with a damp cloth or using an insecticidal soap or spray.
Begonia maculata can also be susceptible to diseases such as powdery mildew and bacterial leaf spot. Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves and can be caused by high humidity and poor air circulation. Bacterial leaf spot is a bacterial disease that appears as brown, water-soaked spots on the leaves and can be caused by overwatering or high humidity.
To prevent these diseases, make sure your plant is not overcrowded and has good air circulation. Avoid overwatering and make sure the soil is well-draining. If your plant does become infected, remove any affected leaves and treat with a fungicide or bactericide according to the instructions.
Toxicity
The Begonia Maculata is considered to be a non-toxic plant, however, they could cause light irritation and vomiting. So you could keep it around small children, but it's best to keep it out of reach from your pets. It's definitely not as bad as most other houseplants.
Propagating your Begonia Maculata
Propagating your Begonia Maculata is quite an easy process. You can take cuttings in different ways, but the easiest way is to cut off part of the stem with a few leaves. You can propagate this cutting in water, Leca, or a porous rock like Pumice. The best time to propagate this cutting is during the spring and summer, because they'll be more likely to grow roots within a few weeks.
If you're going to take cuttings of your Begonia Maculate, be sure to use proper tools for the job. When you use the right pruning shears, you will have minimal damage on the plant and give your cutting a higher chance of growing roots.

What should I do if my Begonia Maculata's leaves are turning yellow?
Yellowing leaves can be a sign of overwatering, underwatering, too much direct sunlight, or a pest infestation. Check the soil moisture level and adjust watering as needed, and move the plant to a shadier location if necessary. Inspect the Begonia for pests such as spider mites or mealybugs and treat with an appropriate insecticide.
