How to Care for Alocasia Amazonica Plant

Alocasia Amazonica Soil Requirements

Lightweight and well-draining potting soil are the best for growing alocasia amazonica. The soil condition will result in the best performance and healthiest houseplant.

Heavyweight potting mediums tend to hold more moisture to cause root rot problems and even plant death. I recommend the use of Jungle Mix for growing alocasia amazonica.

Jungle mix is readily available in many plant stores online. Use one of these potting soils from the Amazon store. These potting soils are ideal for all aroid houseplants.

The best alternative is to create your soil mixture at home. I recommend mixing fir bark, perlite, coco coir, horticulture charcoal, and worm castings in the right proportion.

Alocasia Amazonica Light Requirements

Alocasia Polly needs bright indirect sunlight to maintain the deep-green coloration. The low light condition will make the houseplant stop growing and fade its color.

Direct sunlight exposure will burn the foliages. Besides that, the plant will become limp and droopy in the long run. The issue occurs due to rapid dehydration than water intake.

Place the houseplant in a location that receives medium to bright indirect sunlight. Early morning and late evening direct sunlight will not harm your houseplant.

Alocasia Amazonica Temperature Range

Indoor alocasia amazonica prefers a temperature range of 65-80oF. Any temperature below 55oF will make the plant stop growing and even cause foliage death.

But the underground bulbs will remain alive throughout the dormancy stage. The leaves will re-sprout when the temperature becomes warm in spring and summer.

Maintain a temperature range of 60-80oF to keep the houseplant happy and healthy. Use a digital thermometer (Check the Best Deals on Amazon) to detect indoor temperature changes.

How to Water Alocasia Amazonica

The Amazonian elephant ear loves to grow near water sources in its native habitat to keep the roots moist. I recommend watering the plant more often to keep the soil moist and not soggy.

Water the houseplant twice a week during spring and summer. But reduce the watering frequency in winter due to dormancy. Allow the soil to dry before watering.

A damp condition increases the risk of root rot problems and even plant death. Be sure to inspect soil moisture content before watering your favorite houseplant.

Insert your index finger in the topsoil about 2-3 inches to determine potting soil moisture. If the soil is dry, consider soaking it until water runs through the drainage holes.

Alocasia Amazonica Humidity Requirement

Alocasia amazonica needs a warm and humid environment to thrive well. Maintain moderate to high humidity levels to keep the foliages happy and healthy.

Replicating the rainforest humidity for alocasia Polly can be a daunting experience. Relocate the houseplant to the bathroom due to its high humidity requirements.

Another excellent option is to install a humidifier at home. The device will help to boost indoor humidity that mimics the plant’s native habitat.

Avoid misting the Amazonian elephant ear plant to reduce the risk of leaf spot and other fungal diseases. Either install a humidifier or keep the houseplant in the bathroom.

Alocasia Amazonica Fertilizer Needs

The African mask plant is not a heavy feeder like other tropical houseplants. But fertilizer application every 2-4 weeks during spring and summer fosters plant full potential.

Use a well-balanced liquid fertilizer rich in phosphorus and nitrogen. Remember to dilute the fertilizer before feeding your houseplant. Stop fertilizing the plant in winter due to dormancy.

Be sure to flush the potting mix every few months to avoid salt accumulation around the plant roots. Too much salt is toxic and might ruin the African mask plant’s health.

I recommend the use of homemade organic fertilizer over the artificial counterpart to reduce the risk of over-fertilization. Read my post on how to make homemade fertilizer for houseplants.

Pruning and Maintenance

Alocasia amazonica requires a minimal pruning routine. I recommend removing old or damaged foliages to redirect energy to new growths.

Use a sharp and sterilized blade (Check Best Deals on Amazon) to snip off a leaf. Use rubbing alcohol to disinfect the blade before removing the damaged leaves.

How to Repot Alocasia Amazonica

The African mask plant is less vulnerable to root-bound issues. There is no need for repotting unless it has overgrown the small pot or the potting mix is exhausted.

The best period to repot alocasia amazonica is in springtime. The season is when the houseplant is experiencing active growth.

Use a pot that is slightly bigger than the previous one with drainage holes at the bottom. Transplant the houseplant and fill it with well-draining potting soil.

Alocasia Amazonica Propagation

Alocasia Polly propagation is undertaken during springtime. Take the advantage of repotting the houseplant to avoid ruining it.

Pull the root away from the parent plant and identify as many roots as possible connecting to the offsets. Divide the offsets from the main plant.

Plant each offset in a container and provides ultimate care. Remember to water the plant more often and place it in an area with bright natural light.

How to Clean Alocasia Amazonica Leaves

Alocasia amazonica plant has large arrowhead leaves with prominent veins. Indoor dust at home might ruin the beauty of your houseplant.

Spray the foliages with lukewarm water to remove the dust. Besides that, spray the leaves with a mild soap solution to get rid of pests.

Clean leaves facilitate photosynthesis which keeps the plant healthy and happy. Avoid using shine products to clean the leaves since it might result in a waxy residue.

Common Problems and Solutions


Indoor African mask plants are vulnerable to spider mites. These tiny insects suck juices from the plant and lead to its death if not controlled.

Inspect the leaf’s undersides to identify the spider mites. Use either insecticidal soap or neem oil to eliminate the pests. I recommend Ecogarden Organic Pesticides (Check the Price on Amazon).


Amazonian elephant ear is not plagued by many diseases. It does not imply that the species is invincible to houseplant diseases.

Root rot is the biggest threat to alocasia amazonica plants due to wet conditions. The houseplant does not tolerate a damp environment for an extended period.

If the leaves begin turning yellow or brown, inspect the soil moisture and repot to fresh potting soil. Trim the affected roots with a sterilized pruner before repotting.

Frequently Asked Questions
