Alocasia Amazonica (Elephant's Ear) belongs to the foliage plant of the genus Arum, the Araceae family. It is worth noting that the Alocasia Amazonica has a certain degree of toxicity. The roots and leaves are all toxic, with the stem and stem being the most toxic. Although the Alocasia Amazonica is toxic, there is no need to worry too much, or even give up the idea of planting. Since the toxin of the Alocasia Amazonica only exists inside the plant, the toxicity does not evaporate. Under normal circumstances, except for the single method of direct consumption, there is basically no possibility of causing harm to the body.
How to Grow Alocasia Amazonica
When grown indoors, alocasia amazonica
rarely produces a bloom, which is an insignificant greenish-yellow spathe. Even if you are lucky enough to have your plant bloom, any seeds produced are likely sterile so the only way to propagate additional plants is through dividing offsets from the mother. This is best done while it is actively growing in spring and when you go about the chore of repotting.
Steps for Alocasia Amazonica dividing propagation
- Spread a newspaper out on a table and gently lift the Alocasia Amazonica out of its container and place on the paper, which will collect any mess.
- If the roots are wrapping, gently tease them apart with your fingers before you begin the process of dividing.
- Where the Alocasia Amazonica has produced an offset, gather as many roots as possible connected to it and gently pull it from the mother plant. If needed, use clean pruning snips to snip any portion still clinging to the mother, being sure not to cut into the offset's center.
- Pot in a suitably sized container with drain holes and with the appropriate soil mixture, as outlined in the soil section and in the repotting section.
- Place the new planting in similar light conditions it was originally growing.
How to Care for Alocasia Amazonica
Alocasia Amazonica Lighting Requirements
For the best performance and for the foliage to retain its deep green coloring, it is best to situate your Alocasia Amazonica in a location that receives bright light. In fact, those living in an area where the temperatures and light conditions are not intense can place it in a location that receives direct sunlight.
If placed in a location lacking sufficient light the plant loses its color, including the leaf veins and can eventually die. Even when placed in a location that receives a medium amount of light, the plant won’t be happy and won’t produce the best growth and leaf coloration as when placed in a brighter location.
Alocasia Amazonica Watering
In their native environment, the parents of Alocasia Amazonica
can usually be found growing near a source of water where their roots stay moist. Therefore, it is important to water frequently enough to keep the soil evenly moist but not soggy, especially during the growing seasons of spring throughout summer.
During winter, the plant goes through a dormant stage and active growing stops, so you won’t have to water as frequently as you would while it is actively growing. However, you never want the soil to completely dry out. Checking the moisture content of the soil is easy.
Check the soil’s moisture by sticking your finger into the soil and if the top inch is starting to feel dry to the touch, apply water until it runs from the pot’s bottom drain holes.
Depending on outdoor temperatures and light conditions coming through the window where the Alocasia Amazonica is situated, during the growing season you may have to water one to two times weekly.
In addition, during the dormant season of winter, you may only need to water once every week to two weeks. Regularly checking the soil’s moisture content and applying water as needed will keep your Alocasia Amazonica performing at its best.
Alocasia Amazonica Temperature & Humidity Care
As a tropical plant, Amazonian elephant's ear will go dormant or die if exposed to cold temperatures. It likes to be in a climate similar to its native Southeast Asia, with temperatures ranging between 65 degrees Fahrenheit and 75 degrees Fahrenheit. Additionally, the plant loves above-average humidity levels. You can start by housing your Amazonian elephant's ear in a typically humid room in your home (like a bathroom), but you may also need to place the plant on a humidity tray with pebbles or invest in a small space a humidifier to put nearby.
Alocasia Amazonica Fertilizer
Feed Alocasia Amazonica with general houseplant fertilizer monthly during the growing season (spring to summer).
Alocasia Amazonica Pruning
Quickly remove any yellow leaves or those that develop brown or black spots as that may be a sign of a fungal disease.
Alocasia Amazonica Pests & Diseases Care
Spraying an Alocasia Amazonica with warm soapy water every few weeks helps prevent Mealy Bugs, Scale, Aphids, and spider mite problems. It also keeps the large leaves of the plant dust-free. If an Alocasia does become infested, spray with an ultra-fine commercial insecticidal oil or Neem Oil. This kills both the pests and their eggs.
When alocasia plants are over-watered or when the leaves are consistently wet, they develop a variety of diseases such as crown, stem, and root rot, leaf spot, and Xanthomonas. These diseases usually appear as dark brown or black spots on the leaves, surrounded by a yellowish rim. The best way to prevent plant diseases is to avoid over-watering, keep the leaves dry, and provide good air circulation around the plant. Once an alocasia is infected, quickly remove the damaged leaves and any leaves that have fallen off, isolate the plant from your other plants, and treat with a commercial Fungicide.
Alocasia Amazonica Care FAQ
Why Does My New Little Alocasia Plant Lose a Leaf Every Time it Grows a New Leaf?
An alocasia amazonica
may lose a leaf every time it gets a new leaf when it is an immature plant. Small young alocasia plants are unable to maintain more than a few leaves. This is because the stalk is constantly expanding. As the stalk expands it forces the smaller leaves to drop off. Once the stalk becomes larger and stouter, your alocasia plant will be able to maintain more leaves.
When Should I Repot an Alocasia Amazonica Plant?
The best way to know when it is time to repot an alocasia amazonica plant
is to gently take your plant out of its pot. If the roots have taken on the shape of the pot, it's time for a larger pot. Be sure your new pot is only a few inches larger than your old pot so the roots don't stay too wet and rot. Don't be in a rush to move your plant to a larger pot, these plants like to be root- bound in small pots.
Is Alocasia Amazonica Toxic?
Due to the calcium oxalate crystals contained in the entire plant, Alocasia Amazonica
is highly toxic to people, cats, dogs and horses. Ingestions of the plant cause an intense burning of the mouth, which can lead to swelling of the airways and potential death.
Even the sap can cause skin irritation. Be sure to situate the plant in a location that is out of reach of children and pets.
