This article focuses on Begonia Melanobullata plant care, so let’s discuss its major characteristics.


This blossoming plant belongs to the Begoniaceae family.

Begonia Melanobullata is similar to Begonia ferox as they have similar characteristics. But the first one shows dark-colored bullate from a young age. 

While Begonia ferox requires time to develop and get mature.

Let’s discover the unique characteristics of Begonia Melanobullata. 

When you buy it from the nursery, it comes in a pot and is usually 25 cm tall.

In its native environment, it sticks to limestone precipices and rock holes. 

With its unique foliage, it possesses leaves that are green in color.

It is found in over 2000 varieties and can survive inside and outside.

Let’s move to its care guide!


Begonia Melanobullata

As described earlier, it survives inside and outside in full sun but requires maintenance. 

Let’s explore the factors that influence the plant’s growth. 


Begonia likes well-drained soil that is slightly acidic with a ph of 5.5. To prepare the best potting mix for your plant’s growth, mix two parts of peat moss: perlite, vermiculite, kanuma bonsai soil, and 0.5 part of sphagnum moss. 


Do not keep the plant in the same pot you bring from the nursery. Replace its pot with one size bigger than that. But if you’re growing a little cutting, you may use a 4 5- inches pot with a drainage hole.

Other than the pot, you can also use the basket to grow begonia. It does not grow taller, so it does not get too deep with roots.


It absorbs water from the soil and air. If you live in an area with high humidity, then no need to water the plant until the soil completely dries out.

But if the weather is dry in your area, consider watering your Melanobullata often. 

Tip: When the top 2 to 3 cm of the soil is dry, you should water your plant.


The plant survives on the nutrients it absorbs from the soil naturally. So, the application of fertilizer depends on the growth of the plant. 

If the growth is slower, you should apply diluted fertilizer seldom. 

Remember: Do not apply fertilizer during the winters, as winters are usually a dormancy period for the plant.

Light And Humidity

As Begonia can be grown inside and outside, it services varying light conditions. 

You may place it under low to medium direct sunlight for better growth.

It loves humidity which is why native to areas where humidity is 100%. 

But don’t worry; you can still grow it in your garden or inside. Use a humidifier or pebble to try to adjust humidity requirements.


To take Begonia Melanobullata care, you should maintain intermediate to warm temperatures for better growth. 

The optimum temperature for its growth ranges between 20 to 25 degrees centigrade.


You can repot your plant after 2 to 3 years of planting it. The begonia is a slow grower and should be repotted when it outgrows its pot.

Tip: Repot the plant during the early spring or winter season.

Ensure the pot you place the plant after is bigger than the previous one. 


Begonia can easily be propagated by stem cutting. Here’s the simple procedure that you can follow step by step to propagate your plant.

  1. Using garden shears, cut a few stems from the plant. 
  2. Make sure you are taking cuttings from a healthy plant.
  3. Plant these cuttings in well-drained soil.
  4. Water the cuttings thoroughly and place them under light to grow.

The cuttings will establish roots within a few days.


Now, let’s talk about the common problems of the melanobullata plant.


Begonia is prone to many insects and pests that can harm it. They include spider mites, aphids, whiteflies, and mealybugs. 

If these pests attack your plant, they can result in wilting, stunted growth, and death of the plant. 

You can use pesticides or other biological controls if your plant is infected. 

Other common problems of begonia melanobullata include:

Leaf Spot

If you observe that your plant’s leaves have started turning yellow, it can result from bacterial infection. 

So what can you do to prevent it? You can cut the infected part and avoid over-watering it.

Powdery Mildew

Tip: Sterilize your pruning tools when needed, and don’t use the diseased plant’s soil to plant a new one.
