Alocasia Watering requires that you water them sparingly or keep the soil moist for a long time. Getting their soil to dry fast enough is one of the watering difficulties of Alocasia Indoor plants. A potting mix that dries quickly facilitates the proper oxygenation of roots and prevents them from rotting and fungal attacks.

Below are some unique tips that you must follow while watering your Alocasia plants;

  • Avoid overwatering as it is the main Alocasia killer.
  • Monitor the pot regularly during the growing seasons of Alocasia plants and water them routinely. They need more water to thrive during summer and spring.
  • Before the next watering, wait until the top 2-3 inches of your plant mix dry out but protect it from getting dried completely.
  • Never place your Alocasia plants in completely waterlogged soil. If damp conditions exist, ensure your plant receives a warm environment and maintains good air circulation to enhance the evaporation rate.
  • Though under-watering is preferred over over-watering, Alocasias are not resistant to drought. Thus, keep the soil dry for a short period.

Follow these simple tips while watering your Alocasia plants.

When to Water Your Alocasia Plants? Seasonal Watering Requirements

Let’s understand the watering requirements of Alocasia plants during different seasons.

Alocasia Watering Needs in Summer and Spring

Summer and spring are the growing seasons of Alocasia plants, requiring a more frequent and high amount of water during this time. During this time, weather conditions like temperature and light intensity remain high, speeding up the transpiration rate. The leaves start losing water, and the soil becomes dry during hot conditions. That’s why Alocasia Elephant Ears need more frequent watering.

Water your Alocasia plants when the soil goes 25-50% dry. On rough, water them once a week. Follow a routine carefully; rather, keep checking the soil moisture level. This will indicate when to water your Alocasia plants. If the soil is dry, water your Alocasias; otherwise, wait a few days and let the soil dry.

You can also apply the moisture meter to check the soil’s moisture level and decide about watering your plants.

Alocasia Watering Needs in Winter

In winter, temperature and light intensity become low, and not ideal for Alocasia plants to grow. Plants become dormant due to low light, cold temperatures, low humidity, and shorter span of days. Such conditions are not suitable for Alocasias’ growth. Thus, they stop their growth and conserve energy for the next growing seasons.

Due to reduced growth, Alocasia will require less water in winter. Similarly, the soil will take time to dry out, showing that less frequent watering will be required.

Water your Alocasia plants once in 2-3 weeks during winter, depending on the soil’s moisture level. Don’t use cold water for watering; it will shock the plants, and plants will be stressed.

Allow the water to equilibrate at room temperature, and then use it for watering.

Other Factors Determining Alocasia’s Watering Frequencies

There are a few factors other than seasons determining the watering requirements or frequencies of your Alocasia plants. These factors include;

1.    How does Light Impacts Alocasia Water Requirement?

In their natural tropical habitat, Alocasia plants grow under the canopy of trees and receive filtered light. However, when grown indoors, they need bright indirect light to thrive. Some can even grow in low light, while others grow towards light when placed in a dark corner of your home. The amount of light your Alocasias are receiving determines their growth rate, evaporation rate, and watering needs.

If the plant receives ideal light, it will photosynthesize more efficiently and use more water.

When there is low light, the evaporation rate decreases, the plant shows less photosynthesis, and requires less water. Therefore, reduce the watering rate; otherwise, it will get overwatered.

2.    How does Temperature effects Alocasias’ Watering Needs?

Temperature is also a great factor affecting the watering needs of an Alocasia plant. The plant shows more evaporation when the temperature is high and transpires quickly. As a result, it needs more water to perform photosynthesis and meet other needs.

However, if the temperature is low, like in winter, the plant ceases its growth, and the soil will take longer to dry. Therefore, the plant will need less water for its metabolism.

3.    How does Humidity affect Elephant Ear Alocasia water requirements?

Alocasia plants love to grow in humid conditions, and their watering requirements greatly depend on the humidity levels. If the humidity is already high in the environment, the Alocasia plants will need a little water, and if the humidity is low, the moisture level will go down, and the plant will need more water.

Therefore, it is important to check the humidity level before Alocasia watering. You can use a Hygrometer to see the humidity level. You can use a humidifier to provide ideal humid conditions if there is low humidity.

4.    Soil Impact on Alocasia Watering Schedule

Alocasia plants require well-drained soil to drain excess water and grow better.

If the soil has a good drainage capacity, it will take little time to dry out, and Alocasia plants will require more water. However, if the soil is heavy and retains water, it will become soggy and requires less frequent watering. You can add sand particles, perlite, or pumice so the soil cannot dry quickly.

This way, soil determines Alocasia watering frequencies how often and when to water your Alocasia plants?

5.    Pot size and type for determining Alocasia watering requirements

The pot size and material also determine the watering needs of an Alocasia plant. A clay-based pot will dry out potting mix more quickly, and the plant will require more watering. However, using a plastic pot will help retain moisture for a long time, and less watering will be required.

Similarly, a big-sized pot contains more soil, and water will take longer to drain. This way, the Alocasia plant will require less frequent watering.

Whereas a compact pot contains less soil, and the water drains faster. Your plant will require more frequent watering.

How to Know that Alocasia Plants Need Watering?

Some symptoms or signs indicate that your Alocasia plants need watering.

These dehydration symptoms include;

  • Droopy leaves
  • Curling leaves margins
  • Dried-out potting mix
  • Yellowing of leaves

These symptoms, except dried-out potting mix, can also be signs of other problems. For example, droopy and curling leaves can also be due to pest infestation or overwatering and yellowing of leaves can also result from lack of light or over-fertilization.

How Often Should You Water Your Alocasia Plant?

There is no fixed watering schedule for all Alocasia plants. All you need is to apprehend the Alocasia watering requirements and give water when they need the most.

Specific factors mentioned above affect the watering schedule of your Alocasia plants. Sometimes, you must water your Alocasia Elephant Ears twice a week; sometimes, it can be once a week. Therefore, consider all the factors altering the watering need of your Alocasia.

To determine when your plant needs watering, regularly check the moisture levels of the potting mix. Water your Alocasia plant if its top 2-3 inches are dry.

How to Water Your Alocasia Elephant Ears?

There are various watering methods that you can use while watering your Alocasia plants. Below are three different methods, and switching between them while watering your plants is good.

1.    Continuous Pouring

This is the first method where you keep watering your Alocasias until excessive water starts coming out of the drainage holes. Use this method once a month as it helps to remove all the excess salt build-up.

2.    Quick Pour

In this method, you maintain the aeration of the soil and sook your plant but look no further for the water to come out of the drainage holes.

Use this method when the soil is dry. So, take a chopstick, dig some holes to aerate the soil, and pour water into it. Good aeration ensures that the water gets into the soil and doesn’t rush from the sides.

3.    Bottom Watering

Apply this watering method to water your Alocasia plant when placed in a pot with no drainage holes. This method helps you avoid overwatering. So, please remove the plant, fill the pot with water, place it in it and allow the soil to soak it. Again, remove the plant from the water after some time and place it back in the original pot.

What Happens to Your Alocasia Plant When It is Overwatered?

Alocasia plants love moist soils to grow but are not resistant to overwatering and cannot grow in waterlogged soil. If you water your Alocasias when the soil is not dry, it will result in overwatering and Alocasia plant will develop various issues. Overwatering will cause;

  • Yellow leaves
  • Wilting leaves
  • Soft stems
  • Fungus infestation
  • Pest attack
  • Root rot

When the plant is overwatered, tilt the pot, drain out excess water, and place your plant under bright indirect light.

Take the plant out of its pot, spread the roots and soil on the paper, and let them dry out under bright indirect light. And if you get a foul smell, take the plant out and inspect its roots. Trim the damaged roots, spray fungicides, and repot them into a fresh potting mix.


  • Check the soil moisture and water your plant when it is 25-50% dry
  • Reduce watering in winter
  • Don’t follow a watering routine mindlessly
  • Select the pot with good drainage holes

What Happens to Your Alocasia Plant When It is Underwatered?

Though under-watering is good for Alocasia plants, keeping them dry for a long will negatively affect their growth. Alocasia plants can survive under-watering with thick leaves with good water storage capacity. Underwatering will cause some symptoms in Alocasia plants. these signs include;

  • Wilted and brown leaves
  • Crispy foliage
  • Stunted growth
  • Curling leaves
  • And drooping leaves


You can handle under-watering more easily as compared to overwatering. If your plant is under-watered, give it a good soak of water and aerate the soil to improve its water-holding capacity. Bottom-watering method is applicable to treat under-watering.
