There are a few points you need to consider few things as they are needed to be grown in bright but that has to indirect light, warm temperatures, soil, and high humidity which is being explained in detail above it.   

• Light 
• Watering 
• Temperature 
• Humidity 
• Soil 
• Fertilizer 
• Potting & Repotting 
• Pruning 
• Propagation 

Light:

As per their origin, the Alocasia Macrorrhiza Variegata can be easily grown in the shade of trees but for planting at home, the light requirement ranges from 10,000 to 20,000 lux. You can achieve the light range by placing the pot near a north or east-facing window so that the plant gets sun exposure. But make sure not to expose the plant to full sun that is the afternoon light as it will burn the leaves which can damage the plant. 

Watering:

 They generally best grow in well-draining soil that is moist consistently. You need to water the plant when you find the top inches of the soil dry when you touch it. If you keep the soil wet all the time then there are high chances of growing pests and diseases.  The best way of watering the Alocasia macrorrhiza variegata is by slowly adding the water to the pot and stopping when you find the water has started draining out. Also, do keep in mind not to keep the pot standing in water. 

Temperature:

The plant is a tropical plant so it is best grown in a warm temperature that ranges from 65 to 80 degrees. You need to keep the plant away from the cold air that comes from the air conditioner or fan as the tolerance level of temperature is below 50 degrees Fahrenheit. In summer you can keep the plant outdoors but remember to bring it back before the freezing temperature starts. 

Humidity:

The preferred humidity suitable for the plant is from 60 to 80%. For planting at home a high level of humidity is not possible so you need to provide a more humid zone for Alocasia macrorrhiza variegated. The best way is to group all the plants that do need high humidity and bring a small humidifier for all of them which will help to add moisture in the year and will help the plant to grow quicker full stop the other way is to place a pebbled tree under the plant and will the tree with the water.

Soil:

As the plant needs soil that is well draining but with that it’s important not to have too much wet soil as it will create a situation of fungal diseases such as root rot. You can also measure the pH level for planting Alocasia macrorrhiza variegata which should be between 5.6 to 5. You can create the ideal soil for planting by combining equal parts of perlite, peat moss, orchard bark, and compost.

 

Fertilizer:

If you want the plant to come out with massive leaves then you need to provide them with regular fertilizer. The preferred or balanced ratio is 5-5-5 or 10-10-10.you can use the fertilizer once every two weeks and that too in the spring and Summer seasons. The next step after fertilization is watering the soil nicely and making sure the water reaches the roots of the plant. As in dry soil conditions, the nutrients provided will run out.

Potting & Repotting:

The need of repotting the plant cones every year as the roots of the plant start coming out of the drainage holes. But don’t increase the size of the pot too much, just a few inches bigger in diameter. You need to use fresh potting soil for repotting in a container that needs to have good drainage holes. 

Pruning:

If you find any leaves that are dead or damaged it’s high time for pruning the plant as it is necessary to trim them off so that they don’t develop any diseases and do always look attractive. You need to use a sharp sterilized knife and always cut the leaf stem that is a few inches within the soil level and not plant the trimmed-off side in the soil. 

Propagation:

There are many ways of propagation but the easiest way to divide the plant when it is being repotted is by gently pulling off the offset plant and planting each of those in a different pot. The other way of propagating the plant is by cutting the stem and root and then watering the stem cutting. The preferred condition for propagation is considered the growing season of spring and summer.

But if you are in the seed of seed germination than you can plant them when the seed is mature but it is sure that the germination rate of the seed is very slow and after that, it will take a long time for it to grow big in size.
