How to Grow Alocasia macrorrhizos (Giant Taro)? A Detailed Guide to Care Essentials and Precautions

Alocasia macrorrhizos is a common plant in our daily lives. Its attractive appearance and ease of care make it a favorite among many plant enthusiasts. Below, the editor will tell you about the care essentials and precautions for Alocasia macrorrhizos.

Care Essentials:

1. Watering

If you are growing Alocasia macrorrhizos in soil, the amount of watering depends on the size of the pot. At the same time, the amount of water for Alocasia macrorrhizos also needs to be determined based on ventilation conditions, air humidity, and soil permeability. It is not a matter of watering as much as we want, because growing environments differ, so we cannot use others' methods to water Alocasia macrorrhizos.

However, we can water according to our own situation. If the Alocasia macrorrhizos we are growing is in a small pot, then water only after the potting soil dries, and just make sure water drains from the bottom of the pot. For deep pots, after the surface soil dries, you can dig into the soil to check the color. If the soil below is moist, we do not need to water it. For deep pots, watering once every half a month, or even not watering for a month, is no problem at all.

The environment where we grow Alocasia macrorrhizos must be warm and humid, and it also needs a proper setting. Alocasia macrorrhizos is shade-tolerant, so it can also grow in shady places. However, during the flowering period, Alocasia macrorrhizos needs 3 to 5 hours of sufficient sunlight per day, otherwise the flowers it produces will affect its quality.

2. Soil

This green plant, Alocasia macrorrhizos, does not have high soil requirements. If we use ordinary garden soil or pure sand, Alocasia macrorrhizos will grow very slowly. It is best to use fertile, breathable nutrient soil, such as a mix of perlite, vermiculite, and peat soil in a 1:1:1 ratio to grow it. We can also add some sand to the soil.

3. Temperature

Alocasia macrorrhizos can only grow very well in an environment above 18 degrees. If the temperature is below 18 degrees, Alocasia macrorrhizos will enter dormancy. Growing Alocasia macrorrhizos fears the cold, so by mid-October it needs to be moved indoors for cultivation. In summer, we need to provide shade for it, and we also need to frequently spray water around the plant to cool it down and maintain moisture.

4. Fertilizing

We need to fertilize Alocasia macrorrhizos every month, especially in summer when its demand for nutrients is greater. We need to apply a top dressing of bean cake water or compound fertilizer every 15 to 20 days. The fertilizer Alocasia macrorrhizos likes most is nitrogen fertilizer. If not fertilized, the stem base will become bare, yellow leaves will appear, or the leaves will become smaller.

We need to water it with 2% ferrous sulfate about once every 20 days. This can make the leaves of Alocasia macrorrhizos grow larger and greener. Alocasia macrorrhizos can be placed in the home and then sprayed all over with a 2% paclobutrazol solution. The plant will be compact and delicate, with thick, fleshy leaves, giving it very high ornamental value and making it very suitable for growing at home.

Precautions:

When growing Alocasia macrorrhizos, during the process of watering it, we must pay extra attention. We must not water too much, and we must not let water accumulate in the pot. If water accumulates in the pot, it will cause the roots of Alocasia macrorrhizos to rot. In summer, during the growing period of Alocasia macrorrhizos, we can give it more fertilizer, but in winter we need to reduce the amount of fertilizer, or not fertilize it at all, because winter is the dormant period for Alocasia macrorrhizos.

The above is the care essentials and precautions for Alocasia macrorrhizos compiled by the editor of Huinong Network. Have you all learned them? Alocasia macrorrhizos is a plant with very high ornamental value. Plant enthusiasts who like it should not miss out!

How to Grow Alocasia macrorrhizos - How to Propagate Alocasia macrorrhizos

Alocasia macrorrhizos is also known as Dripping Lotus and Buddha's Hand Lotus, and it also has medicinal value. Next, let us take a look at the cultivation methods and care essentials for Alocasia macrorrhizos.

Alocasia macrorrhizos, of the Araceae family and Alocasia genus, also known as Dripping Lotus, Buddha's Hand Lotus, etc., is a perennial evergreen herbaceous plant with medicinal value. Under warm, humid conditions with sufficient soil moisture, water will drip down from the leaf tips or leaf edges. Moreover, its flowers resemble Guanyin, hence the name Dripping Guanyin (Alocasia macrorrhizos).

Alocasia macrorrhizos is a perennial upright herb, with plants reaching up to 2 m tall. It has fleshy rhizomes underground, long petioles with broad leaf sheaths, and large leaves that are peltate, broadly arrow-shaped, clustered at the top of the stem, with pointed tips, slightly wavy margins, and prominent midribs. The spathe is yellow-green, with a spadix inflorescence.

Propagation of Alocasia macrorrhizos

(1) Sowing: Wild plants often bear seeds. Sow in spring. The suitable germination temperature is 25-28°C, and germination occurs 20-25 days after sowing.

(2) Cuttings: Carry out in April. Cut thick stems into stem segments about 10 cm long with several buds as cuttings. After drying slightly, insert them obliquely or lay them flat on the seedbed. When laid flat, the depth should be just enough to bury the stem segment. The cuttings can also be inserted directly into pots. After insertion, keep the substrate moist and the ambient temperature at 25-2TC; roots will form and they will survive after 4-5 weeks.

(3) Division: Potted plants easily produce many small plantlets at the base. In April, division can be carried out along with repotting. Separate the small plantlets from the mother plant and plant them separately. Division is best done when the temperature reaches 20C or higher. On the basis of keeping the substrate moist, new shoots will emerge in about 20 days.

Cultivation Methods for Alocasia macrorrhizos

1. Temperature: It likes warmth and grows rapidly above 25°C. The most suitable temperature for growth is 25-30C. It has a certain cold resistance, and the overwintering temperature only needs to be maintained above 2°C.

2. Light: It likes semi-shade and cannot tolerate exposure to strong sunlight. From May to September, shading should be provided, blocking about 50% of sunlight. At other times, it should be given sufficient sunlight. It cannot tolerate excessive shade, otherwise the petioles will become thin and elongated, and not only will the plant shape be unattractive, but it will also break easily.

3. Watering: Because the leaves are large and consume more water, it is afraid of drought. It likes a slightly moist soil environment. During the growing period, watering should follow the principle of "alternating dry and wet, leaning toward moist." Water thoroughly; even watering a bit more is fine. Especially in hot, sunny summer, pay even more attention to water supply to meet the plant's water requirements.

4. Environmental humidity: It likes a humid environment and dislikes dry air. During the growing season, on sunny and dry days, water should be sprayed frequently on the branches, leaves, and surroundings to maintain relatively high air humidity.

5. Fertilizing: It likes fertilizer. Because of its large growth, nutrients need to be supplemented in time so that the stems can grow thick and strong and the leaves can be large, deep green, and glossy. When lacking fertilizer, the leaves are small and yellow. During the growing period, apply a nitrogen-based fertilizer as a top dressing about once every 10 days. After autumn begins, stop applying nitrogen fertilizer and apply 2-30 phosphorus and potassium fertilizer as a top dressing. Stop fertilizing in winter.

6. Pruning: Yellow leaves should be cut off at any time. Because the petioles are long, when moving, placing, and caring for the plant, avoid breaking the petioles. If they are broken, they should be cut off promptly.

7. Repotting: Repot once every 1-2 years. It does not have high soil requirements, but it likes fertile, loose, and well-drained sandy loam. The substrate can be prepared with materials such as leaf mold, garden soil, peat soil, and river sand. If sufficient base fertilizer is applied, the leaves can grow large and thick. Because the leaves are large but few in number and the petioles are long, when moving the plant and caring for it, avoid damaging the leaves, otherwise the ornamental value will be reduced.

Cultivation Essentials and Precautions for Alocasia macrorrhizos - How to Cultivate Alocasia macrorrhizos? Cultivation Methods for Alocasia macrorrhizos

I. Suitable Temperature

First of all, if you want to grow Alocasia macrorrhizos well, you must know that Alocasia macrorrhizos can only grow well at a temperature not lower than 18 degrees. If the temperature is below 18 degrees, it will cause Alocasia macrorrhizos to enter a dormant state, and it will also cause Alocasia macrorrhizos to stop growing. Temperature selection is a necessary prerequisite for growing Alocasia macrorrhizos well.

II. Appropriate Light

We all know that Alocasia macrorrhizos is a plant that likes shade, but Alocasia macrorrhizos also needs an appropriate amount of light. However, the light should not be too strong. If Alocasia macrorrhizos receives too much light, it will cause Alocasia macrorrhizos to become "wilted." You should know that Alocasia macrorrhizos likes a warm, humid, and shaded environment, but during the flowering period it needs sufficient sunlight, otherwise the spathe will be greenish, affecting quality. Therefore, Alocasia macrorrhizos still needs an appropriate amount of light time. Ensuring about three hours of light per day should be about right.

III. Sufficient Moisture

No matter what plant it is, water is also very important. Plants like Alocasia macrorrhizos need relatively more water in summer. At noon in midsummer, water should be sprayed on the leaves to increase air humidity. Only in this way can the leaves of Alocasia macrorrhizos be large and thick. If it is too shaded, the leaves will enlarge but become thinner, which will still greatly affect the aesthetic appeal of Alocasia macrorrhizos. Therefore, the need for water is also indispensable.

IV. Appropriate Fertilizing

Alocasia macrorrhizos is also a plant that likes fertilizer. Apply nitrogen, phosphorus, and potassium fertilizer to Alocasia macrorrhizos every month so that it can grow rapidly. Fertilizing Alocasia macrorrhizos about once every 20 days can make its leaves larger, thicker, and greener. If Alocasia macrorrhizos is not fertilized for a long time, the lower part of the stem will become bare, yellow leaves will appear, or the leaves will become smaller. Therefore, appropriate fertilizing is also very crucial.

V. Moist Soil

Due to the influence of the growth habits of Alocasia macrorrhizos, it should be watered more in summer, but not excessively. It is enough to roughly ensure soil moisture. There must not be water accumulation in the soil, otherwise the tubers of Alocasia macrorrhizos will rot. In winter, during dormancy, water less. Always follow the growth habits of Alocasia macrorrhizos when planting.

VI. Precautions

1. The white sap in the stems of Alocasia macrorrhizos is toxic, and the water that drips down is also toxic. Accidental contact with or ingestion of its sap will cause discomfort in the throat and mouth, and a burning sensation in the stomach. Special attention should be paid to preventing young children from accidentally ingesting it. However, Alocasia macrorrhizos is not a carcinogenic plant.

2. Precisely because Alocasia macrorrhizos is toxic, skin contact with its sap will cause itching or strong irritation, and eye contact with the sap can cause severe conjunctivitis, or even blindness. Accidentally eating the stems and leaves will cause symptoms of nausea and pain, and in severe cases can also cause suffocation, leading to cardiac paralysis and death. Therefore, contact with Alocasia macrorrhizos should be minimized as much as possible, and families with children had best not grow it.
