Alocasia plumbea ‘nigra’ plant care guide

Now, I will suggest to you the caring guides of alocasia plumbea ‘nigra’. The segments of care that I am going to discuss here are-

  • Light requirement 
  • Watering guide 
  • Best soil medium
  • Temperature and humidity measurement 
  • Best fertilizer 

Light requirement 

Alocasia plumbea ‘nigra’ loves to stay in partially shady conditions. Full sunlight is problematic for their body activities. If you put them in scorching light for hours, the leaves get burnt and the plant becomes stressed. So keep them in partial shade for their better development. That’s why they are easy to maintain as indoor plants. 

Watering guide

The next one is watering techniques. You should water your plant once or twice a week. But make sure that the soil has enough moisture but no water is clogged in the soil. You should notice if the drainage is proper or not.

Best soil medium

I recommend slightly acidic soil having a pH of 5.0-7.5 as the plant rooting medium which is highly enriched with nutrients. You can mix perlite, coco coir or sphagnum moss with the soil. It will work as a supportive nutrient. The soil should have moisture-retaining quality and proper aeration stability. 

Temperature and humidity measurement 

In the case of temperature measurement, I always suggest keeping the range between 60°F to 85°F. This temperature is favorable for the growing condition and reproductive period of the plant. Along with this, you have to maintain appropriate humidity that is 60-70%.

Best fertilizer 

The final one is the fertilizer requirement. Don’t over-fertilize your plant as it will make the leaf burn and kill the plant. As plumbea ‘nigra’ is a hardy plant, it needs fertilizing once a year in the early summer or late spring. Additionally, you can use liquid fertilizers for them during their growing period. Dilute the fertilizer with water and pour it while watering.

Alocasia plumbea ‘nigra’ plant propagation

Now, comes the propagation procedure. For a well-developed new plant, an undisturbed propagation period is an important issue.

Mother plant selection: Firstly, you have to select a healthy mother plant that is disease-free and well-established.

How to repot alocasia plumbea ‘nigra’ plant?

Repotting plumbea nigra is an easy procedure but it requires skills. Firstly, you have to uproot the plant without damaging the roots. Then, take a new pot and prepare it with the soil mixture you made during propagation. Finally, plant it in the prepared pot.

Why are my alocasia plumbea ‘nigra’ leaves turning brown?

Alocasia plumbea ‘nigra’ can turn brown due to overwatering or over-fertilization. When you water them more than it’s necessary, the root system faces stress and a root rot problem is initiated which is expressed through brown leaves. Again, too much fertilizer concludes in leaf burn making the leaf brown.

Why are my alocasia plumbea ‘nigra’ curling?

Alocasia plumbea ‘nigra’ leaves may become curly and crispy because of underwatering and excessive temperature. Too much temperature makes the leaves dry. If you don’t water your plant properly at that time, the cells of the leaves get dry and finally it becomes crispy and curly.
