Alocasia scalprum plant care guide

Now, I will describe to you the care guides of this plant. To avoid some plant physiological issues, you need to follow these criteria for your better plant population. 

Alocasia scalprum light requirement 

First of all, you have to concentrate on the intensity of light that you are making available for your plant. Scalprum plants love to be nourished in bright and indirect light.

The best soil for alocasia scalprum

After that, I am going to talk about the soil medium where they will remain. Loose soil having a moderate textural bond is perfect for them. That means sandy loam soil where moisture and nutrients will be held but water should be drained out is perfect for them. You can use perlite, coco coir, moss etc. for better nutrients. 

Temperature and humidity for alocasia scalprum

Therefore, you should be conscious of the available temperature and humidity. Don’t forget that they love to remain at 50°F to 75°F. Temperature fluctuation creates a detrimental impact on them. Again, they can suitably grow in more than 50% humidity. Hence, observe your weather condition and make the proper availability of these factors.

How to repot alocasia scalprum plant 

Repotting alocasia scalprum plants is similar to the propagation system. It is done in case of root rot, overwatering and pest infestation problems. The activities are-

  • Uprooting the plant from the old pot.
  • Preparing a pot with soil mixture consisting of soil, coco-peat 
  • Planting the seedling in the new pot.

Why are my alocasia scalprum leaves turning yellow?

Alocasia scalprum leaves may turn yellow due to nutrient deficiency or virus attack. If you notice an intermingled color of green and yellow, then it is a virus attack. Apply insecticides to sort out this problem.  You may need to use fertilizers if it is caused by nutrient issues.

Why is my alocasia scalprum curling?

Have you seen any curly leaves in your scalprum plant? I experienced this topic in my plant. That was for over-watering of which I was ignorant. Then, I researched and found that over-watering creates root rot which is harmful to the plant. So if you are in the same position as me, then stop watering your plant and repot it if needed.

Alocasia scalprum vs alocasia heterophylla plant 

Are you getting confused between alocasia scalprum and alocasia heterophylla? Well, let me clear it up. Both of these plant leaves are narrow and large, having so many veins. But the leaf color makes the difference as scalprum has dark green leaves and heterophylla consists of greyish green leaves.

Alocasia scalprum vs alocasia longiloba plant

Another doppelganger of my favorite scalprum is alocasia longiloba. They resemble scalprum in size, shape and leaf color. But the veins are moderately fewer in longiloba than in alocasia scalprum and this is how you can differentiate them.

Yes. They have some variegated hybrid varieties. These may be combinations of light and dark green or combinations of white and dark green. Bright sunlight is important to retain this variegation.

Alocasia scalprum plant is still not found in some temperate localities. As they are habituated in tropical climates, they can hardly survive excessive frost which makes them rare in those areas.
