Let’s start

Main causes of alocasia polly yellow leaves

The light

No doubt every plant needs proper light for its entire life cycle to grow healthy. But plants like Alocasia polly do not need direct bright light. Putting it in the brightly lighted room is not all about growing alocasia polly plants. They need filtered light which means they do not thrive under direct bright light.

The plants absorb light to make their food. If the light is too bright or too dim then plants become unable to make their food. If they do not make and eat their food then they will die in few days.

To fix this problem you need to put the plant in an area where it gets balance light. Once you put it in indirect bright light the yellow leaves turn into green color in few days.

Extra soil moisture

Regular moist soil is the secret of growing houseplants. By giving water to the plant, you can control the soil moisture. But the problem starts when the soil becomes soggy. Plants cannot grow in waterlogged soil. So, you need to be careful about watering the plants.

Every plant needs more water on hot summer days. Because the high temperature in the daytime dries the soil quickly. Hence the plants need regular water.

In winter days the plants go to the hibernation stage. This means plants stop growing and when they do not grow, they do not need much water and nutrients.

Giving regular water on winter days triggers the root rot and turns the plant leaves from green to yellow.

To fix this problem buy a soil moisture meter. This meter will help you to know the soil moisture in seconds before watering plants.

You also need to use the well-draining soil in plant pots. This type of soil does not absorb much water. But it sucks the good amount of water that keeps it moist for a long time.

All the above things are useless if the pot does not have a draining hole. This hole at the bottom of the pot saves plants from extra water. The extra water comes drains out of the draining hole.


As it is a rain forest plant so it needs high humidity to live. I understand you cannot give it ideal growing conditions like the forest. But low humidity causes yellow leaves. There are many ways y which you can increase the humidity.

The easy method is to use a humidifier. Put it in the plant room and turn it ON. If you do not have a humidifier at home. Then you can put pebbles in the tray and fill it with water. then put the plant pot on it. the water in the tray slowly evaporates due to the hot climate. The water vapors increase the air moisture around the plant pot.

If the problem is worst your plant need immediately high humidity. Then move the alocasia pot in the bathroom. It is the place in your house where we have naturally high humidity.

Let it there for a minimum of 24 hours. Your plant will revive itself easily.

Low water

Low water also causes yellow leaves of plants. Never use unfiltered water for watering plants. Such water includes many heavy minerals. Calcium, copper, mag in the water gets collected in the soil. This build-up of minerals blocks nutrient absorption. This results in nutrient-deficient plants. the first sign of nutrient deficiency is yellow leaves.

To fix it always use filtered water for watering plants. The that you drink is good for your plants. In some areas of the country. The tap is considered to be safe for drinking and watering plants. But the water authorities add chlorine in the water to kill bacteria.

They add it once a month. When the water has chlorine content then you need to avoid it for watering. The taste of the water will tell you that there’s chlorine in it.

Insects and plants

Common insects like Aphids, Mealybugs, Spider mites. All of them are commonly found on Growing Alocasia polly. They live on the nutrients. These pests attach themselves to the plant leaves and suck the nutrients.

They make the plant nutrient deficient and turn bright green leaves into yellow color.

Keep the growing area neat and clean. Your plant pot should be clean and dust-free. These insects get attracted to dust and humid places.

To prevent them use neem oil. Spray it all over the plant, it will not harm it. In fact, professional gardeners use neem products on all plants. because it has anti-bacterial and anti-fungal properties. It can save your plant from pests and diseases.
