What to Do When the Leaves of Alocasia Turn Yellow? Learn These Few Tricks to Solve It Easily

Alocasia, also known as giant taro, is a common indoor foliage potted plant. Because it is highly ornamental and purifies the air when placed indoors, it is deeply loved by flower enthusiasts. However, during care, the phenomenon of yellowing leaves often occurs, so what is the reason for Alocasia leaves turning yellow? How to solve it?

I. Introduction to Alocasia:

1. What are the habits of Alocasia?

Alocasia prefers partial shade and is suitable for growing in a 20-30 degree environment. In high temperatures, it can grow normally as long as the soil is moist and it is shaded. In winter, it can grow normally as long as it is given a certain amount of scattered light. It does not have high requirements for water and fertilizer; as long as the principle of less in winter and more in summer is followed, it can grow normally.

2. Where does Alocasia come from?

Alocasia has many places of origin and is produced both domestically and abroad. Abroad, it mainly comes from northeastern India, Bangladesh, Indochina, Indonesia, the Philippines and the Malay Peninsula; domestically, it mainly comes from tropical or subtropical regions such as Taiwan, China, Fujian, Jiangxi, Guangdong, Guangxi, Hunan, Guizhou, Sichuan and Yunnan.

3. What benefits does Alocasia have?

Purifies the air, clears heat and detoxifies, dissipates nodules and reduces swelling, attracts wealth and averts disaster

II. What to Do When Alocasia Leaves Droop and Turn Yellow? Teach You Eight Tricks So the Leaves Never Turn Yellow Again!

Cause 1, insufficient light: Alocasia prefers shade but is not tolerant of strong light. If it is placed in a place lacking light for a long time, the leaves will be unable to carry out photosynthesis and will appear yellow due to a lack of chlorophyll.

Solution: Place Alocasia in a living room or bedroom with scattered light so it can carry out photosynthesis. But in summer, it needs to be moved to a cool place for partial shading, and kept ventilated at all times so it can grow freely.

Cause 2, unreasonable watering: Alocasia likes to grow in a moist environment. If watering is not thorough or the watering method is incorrect, the root tips will lack water and the leaves will turn yellow. In addition, irregular watering can also make the leaves turn yellow.

Solution: In spring, water once every 5 days; in summer, water thoroughly once every 3-5 days, but do not let water accumulate; in autumn, it is best to water once every 5 days. If the temperature is very low and close to winter temperatures, watering once every week or 10 days is enough; in winter, spray water on the plant once every week, and do not let water accumulate, so as not to affect root respiration.

Cause 3, insufficient soil nutrients: Alocasia likes to grow in loose, well-drained sandy loam or loam rich in humus. If the potting soil is too alkaline or the potting soil is not changed for a long time, the plant will lack nutrients and show yellowing, drooping and other phenomena.

Solution: As much as possible, choose loam or sandy loam with good drainage and rich in humus for planting. You can also use a mixture of river sand, peat soil, leaf mold and thoroughly rotted cake fertilizer to make nutrient soil for planting. In addition, change the pot once every spring and loosen the soil once a month to ensure good permeability of the potting soil.

Cause 4, temperature too low: Alocasia is a tropical plant. Too low a temperature will freeze and damage the root system, causing the leaves to gradually turn yellow. In addition, moving the plant outdoors immediately after winter will also make it unable to adapt to climate changes and cause the leaves to turn yellow.

Solution: In winter, move Alocasia indoors as much as possible, and wait until spring to move it outdoors. In addition, in summer, properly shade it or move it to a cool place with scattered light.

Cause 5, poor ventilation: Alocasia likes to grow in a ventilated environment. If ventilation is poor, the leaves will have difficulty breathing and turn yellow.

Solution: Move it to a cool, ventilated place. If it is winter, avoid placing it at an air conditioning vent, so that the moisture in the leaves is not blown dry, causing withering and death.

Cause 6, unclean leaf surface: The leaves of Alocasia are the site of photosynthesis. If the leaves are not clean, it will hinder photosynthesis and cause the leaves to turn yellow.

Solution: Gently wipe the dust off the leaves of Alocasia with a cloth. If one cleaning is not enough, wipe again after two hours to ensure the leaves are clean.

Cause 7, pest impact: During the growth period of Alocasia, red spider mites will appear, and red spider mites like to suck the sap on the back of the leaves, causing many small white spots to appear on the leaves and making them slowly turn yellow.

Solution: Use 40% dimethoate emulsion or 80% dichlorvos 1500 times spray to kill them. When cleaning up, try not to touch them directly with your hands, so as to avoid poisoning.

Cause 8, human damage: When parts such as the leaves and branches of Alocasia are damaged, the transport system will be impaired, so the leaves cannot receive nutrients and turn yellow.

Solution: Try not to touch the plant. Especially if there are children or elderly people at home, it is best to place it out of reach to prevent leaf damage.

III. Can Alocasia purify the air?

Alocasia can purify the air. Because Alocasia has very large leaves, it can absorb carbon dioxide from the air day and night and release oxygen together with chlorophyll, so Alocasia is a natural small oxygen bar, and especially for small households, the air purification effect is most obvious. In addition, it can also absorb dust from the air, so when there is a lot of dust on the leaves, wipe it off with a cloth to prevent the leaves from turning yellow.

In summary, Alocasia leaves turning yellow is mostly caused by factors such as insufficient light, insufficient water or poor ventilation. Therefore, during cultivation, try to do a good job in basic management work such as changing soil, water and fertilizer, so that it can grow greener and greener.
