To grow a plant successfully, you need to know about the growing season, potting mix, sunlight, watering, fertilizers, pest & diseases, etc. This helps to take best care for the plant. And in article I am going to share with all these necessary details.

Growing Season

Alocasia can grow very well from spring to summer season. But during winters the plant goes under dormancy. You can grow alocasia very easily in plant hardiness zones 10 and 11.

As this plant is native to Asia, so growing this plant in tropical to sub-tropical climate is ideal. The ideal temperature range for growing alocasia is between 15 – 27 degrees Celsius. Below 15 degree Celsius the plant goes under dormancy.

Potting Mix

This gorgeous houseplant loves well drained, loose loamy to sandy loam soil. Hence, if you already have loamy soil with such properties then you do need to prepare any special potting mix. Just add fertilizers and your ready to begin.

But, if you have clayey soil that retains water for a longer period of time then you definitely need to prepare a good potting mix. Prepare the potting mix with 40% normal garden soil + 30% river sand or perlite + 30% any bulky organic manure like vermicompost.

You can also mix a hand full of neem cake fertilizer to the potting mix. This will help to prevent the plant roots from fungal diseases.

Selection of Pot

For growing alocasia, you need to select the pot according to the present size of the plant. A small alocasia plant of size around 12 inches can easily survive in a 6 inches pot. However, if the roots start to emerge out from the drainage holes then its time for repotting.

You can select earthen, cemented or plastic pots for this beautiful houseplant. Make sure that the pot has at least 3 to 4 drainage holes at the bottom. Water logging condition in the pot can damage your plant.


Well this one is the most important part for caring of alocasia. Sunlight requirement varies according to the variety. Many variety can do well in bright indirect sunlight but few varieties needs bright direct sunlight.

It is not possible to have detailed knowledge about each and every variety. So the best practice is to check the area in which the plant is kept in the nursery. If it is growing well under direct sunlight then it is fit for that condition.

You can also consult the seller or grower about the sunlight requirement of that variety. However, alocasia plant perform well under bright indirect sunlight.


Alocasia loves moist soil but hates soggy soil. Keep the soil moist but also take care of the drainage to remove excess water. I do not prefer fixed watering frequency. But, I love to water them whenever the top layer of the soil seems dry.

I gently apply water till it comes out from the drainage holes. And then its done. You can also mist on the plant whenever the atmospheric moisture goes below 25%.

Depending on the size feeeding capacity of the alocasia plant increases. You can start feeding your plant from spring season with 2 handful of organic manure once after every 30 days till summer season.

Stop feeding alocasia from late summer season as the plant has to prepare itself for dormancy during winters. You can also feed with liquid fertilizers such as waste decomposer or jeevamrut.

Pest & Diseases

Alocasia are sensitive plants and can affected by crown rot, stem rot, root rot, leaf spot disease, etc. The general symptoms are black to brown spots with yellow rims around on the leaves. Avoid over water or wetting the leaves while watering your plants.

Pests like aphids, mealy bugs, spider mites etc. can harm your plant. In case of disease or pest infestation spray neem oil mix weekly during evenings to save your plant.

However, prevention is always better than cure. I prefer spraying any organic pesticides or insecticide weekly on my alocasia plant. This helps to keep the plant pest and disease free.

Alocasia is a very toxic plant. So I will definitely advise you to take proper care while handling this plant. Keep this plant away from your kids and pets. Wash your hands with hand wash after touching this plant.
