How do you care for Alocasia Calidora?

How do you care for Alocasia Calidora?

Alocasia Calidora is unique and pretty rare. Just like various other members of the family Araceae, Persian Plam fancy for moist soil with good drainage. For the prevention of root rot, an adequate amount aeration of the roots is necessary. This plant tends to grow in the shade as well as in the partial sun. 

It will be best if you read it all to explore what steps you must take to grow this unique plant at home. Let’s break it all! 

Initial Care at Home

You must put the plant in a fully bright space in your living room; for instance, near a glass window receiving light. Alocasia Calidora plant does not require direct sun but a very bright indirect light; leaves will start drying if indoor humidity level goes down. So, make a humid environment for the plant to prevent drying. Interestingly, Calidora leaves grow towards the light, so keep turning the plant to prevent it from bending over. 

In summer, Elephant Ear Plant can be taken outside in the garden and kept under a shade receiving indirect sunlight. When taken care of appropriately, it grows new leaves regularly. Its oldest leaf typically dies off. Be cautious the plant can drip. So, take care of the wooden floorings!

sunlight requirement

Does Alocasia Calidora like Sun or Shade?

Being a tropical plant, Alocasia Calidora remains happy in medium to high indirect light levels. The indirect sunlight is enough for the plant, which entitles you to keep it indoors. During the summer season, you can also keep it outdoors in a shaded place. However, in winter, low temperatures at night can damage tropical resident plants like this one. 

Continuous indirect sunlight is required to impart and maintain the excellent color of the leaves. Direct exposure of Calidora to sunlight may cause its leaves to scorch. 

If you keep the pot in some dark place in the home, grow light can also meet the light requirements for growth in full potential. 

watering requirements


Alocasia Calidora is a constantly moist soil lover, but adding too much water can make the soil soggy and cause various plant damage. This is because its roots are not resilient to water-logged soil. In the same way, watering less than required also puts the plant under stress. Under-watering and over-watering can be challenging for the plant, so let the soil dry a bit before watering it. Do not let the plant dry entirely; otherwise, it may drench.

It is the best practice to check soil conditions before watering. It will help you get rid of many issues that may arise otherwise. These issues include water-logging or droopiness, causing significant damage to the roots and foliage of the plant. To ensure the adequate watering of plants, do not rely on the watering schedule because it may fluctuate with the water requirements by the plant in the respective season. Furthermore, the watering needs also depend on your indoor climate, type of pot, and composition of potting soil. We highly recommend checking the top 2 inches of soil. Consider adding water if the soil is dry; otherwise, there is no need. 

To do so, having a sensor or moisture meter is highly encouraged because it is the most accurate and hassle-free method to let your plant survive in good water conditions.

Another thing to keep in mind before watering the Calidora is the season. During a warm and dry summer, the growing season, plants require more water than usual. On the other hand, in winter, which is the fall season, Alocasia Calidora needs much less water content to survive. 

humidity and temperature

Humidity and Temperature

Persian Palm enjoys warm and humid conditions because of its tropical origin. A balmy warmth of about 65 to 85 degrees Fahrenheit is advantageous to evade any possible damage to the plant. That said, the plant thrives in higher humidity levels, such as summer and dry seasons. For this purpose, you can also place it near a heater.

Besides aiding in the extraordinary growth of the plant, higher humidity levels also help keep the spider mites to which the Alocasias Calidora are more susceptible. 

Like many other Alocasia plants, Calidora is also very sensitive to cold conditions. Therefore, keep the plant away from cold drafts from windows or air conditioning.

If you notice low humidity levels, keeping a pebbles tray or a humidifier near the plant is what it will love. Besides all that, to ensure healthy growth, place Calidora near a window so it can have proper airflow and ample indirect light. Using a hygrometer to monitor humidity and temperature is a good practice. It will help you take accurate readings of various attributes necessary for plant growth.

soil requirement

Soil Requirements:

Calidora thrives in soil that has good drainage and can stay moist. Yes! We know these terms are opposite to each other; the soil shall be able to retain enough moisture to keep the roots hydrated, whereas the soil mix shall drain the excess water quickly. Alocasia Calidora likes rich organic soil with pH ranging from 5.5 to 6.5.

You can use a rich and well-draining potting mix for indoor plants for proper growth. Also, you can make a good mix yourself. You can use a 1:1:1:0.5 mix of Potting soil, Orchid bark , Perlite, and Activated charcoal . Please ensure your pot has good drainage and pour out the excess water quantity in the cachepot of the drainage tray. You can replace perlite with pumice in this potting mix for better outcomes. 

Besides that, you can also choose various potting mixes available in the market such as:

Whenever you care choosing a ready made potting mix for your Alocasia please make sure it has components that are chunky and well draining.



The most exciting thing about the Calidora is that it is easily manageable and usually trouble-free. So, it does not require frequent re-potting and it thrives more if the roots are slightly cramped for room. It is also a fast grower. It goes dormant in the winter and waits for the regular growing seasons to return. 

For the best possible growth, we recommend you re-pot the beautiful Alocasia in well-aerated and well-draining soil after a year. The best time for practicing the Calidora plant repotting is spring and early summer which are the growth season for the plant. Furthermore, you must change the pot if you notice roots bulging out of the pot or if you have to water the plant more frequently.

Remember that Calidora does not enjoy it when you move it from one pot to another, and it may shudder and stain. So, don’t re-pot unless it is rootbound. Make sure that the size of the new pot is one size larger than the previous one. Also, make a fresh potting mix and soil. 


Propagation of Alocasia Calidora

An Alocasia Calidora plant grows better during the summer season or mid-spring season. Do not propagate your gorgeous Calidora during winter as the plant is in a dormant phase and propagation will be unsuccessful. Various plant propagation methods include seed propagation, layering, cutting, grafting, budding, division, and tissue culture techniques. You can use the rhizome method to propagate Alocasia Calidora. 

Before starting the procedure, make sure to disinfect and clean all the working tools. Then, use sharp blades. 

Rhizome Propagation:

A Step-by-Step Guide

  • After exposing roots, you can explore multiple clumps of roots, like some offsets (baby plants). Gently separate a few of the baby plants. Use a pair of scissors or disinfected knife if the roots are too tangled. 
  • Now, you have separated your Alocasia Calidora. 

It is exciting as every clump of Calidora has its mini root system, so there is no need to wait for the plant to develop roots. Plant the babies in separate pots, place them in a highly humid place, and wait for new growth in a few weeks.
