1. Overwatering

Yellow leaves are a major symptom that you could be overwatering your plants. You should check the soil instantly and review your watering pattern. Check if there are any signs of rot in the roots.

2. Lightning Issues

Lightning is a curial need for your Alocasia plants. When light exposure is not enough, Alocasia plants are bound to turn yellow. They are sometimes known as low-light plants as they grow in tropical shades.

However, the lightning in forest conditions is brighter than in most indoor conditions. If they are indoor plants, you should place them close to a bright window and ensure to protect them from intense sunlight.

Changes in seasons could also set in. An Alocasia plant that usually blooms near a bright window could start to have issues as the autumn light conditions dwindle. If you notice pale or color changes in your plants, you should move them to a brighter spot.

You should also make sure that the light is not too bright. The leaves could start to turn yellow or brown if they are overexposed to light. You could even see signs of over bleaching or over scorching.

 3. Temperature

The decline and yellowing of your Alocasia leaves could be signs that your plants need a warmer location. Alocasia excels in warm conditions and, they do well in temperature ranges of 18°C and 29°C.

These plants cannot tolerate frost conditions and, they begin to suffer in temperatures below 13°C. If your indoor temperature is way too cool, your plants might not have the warmth conditions that they need.

You must ensure that the temperature does not fluctuate too much or too quickly. Some growers use a heating pad to heat the roots of their plants to keep the roots warmer than the room temperature.

4. Humidity

Alocasia is a humidity-loving plant. But, they could grow in low humid conditions. They best prefer levels above 60% or 70%. The yellowing of their leaves with brown edges or tips could be a symptom of low humid conditions.

This color change happens gradually in the leaves all over the plants. The safe humid region is 50%, even though some growers have seen the plants grow in levels below.

If the humid conditions your plants are in is below average. You can step it up by grouping the plants with other tropical plants.

Do ensure to place water-filled trays close around. If your plant is growing in low humidity conditions, you can support it with monitored watering.

A humidifier could also come in handy to help the humid conditions. If you don’t have, get one from here.

5. Nutritional Deficiencies

A lack of nutrition could also be one of the reasons why your Alocasia plants are turning yellow. They grow well in warm conditions and, feeding them every two to four weeks will do a lot of good.

If the nutrient levels start dropping, they accelerate the retirement of aging leaves to use the resources.

Once you suspect a lack of nutrition, please don’t rush the feeding pattern. Take it in phases to prevent shock conditions.

If you have not made use of fertilizers before, you have to work out a feeding plan. But if you have made use of fertilizers, continue with your plan but step up the quantity a little.

Monitor the leaves carefully for weeks after you have applied fertilizers. If you do not see any notable changes, go back to the former feeding plan and check other factors that we have aforementioned.

If you notice an improvement, however, continue with the correct dosage. Do not keep increasing if you don’t notice any improvement.

6. Pest Infestation

Alocasia plants could easily be affected by common pests like thrips, aphids, spider mites, and scales. The big, juicy, and soft leaves are a big attraction for pests at any time, so you must endeavor to check your plants often.

You will see a plant infested by a pest have its leaves turning yellow as the pest suck out life from them. If you notice tiny white spots or small webs and congregate close to the dormant veins of the leaves, they could be signs that the plant has gotten infested.

If all you notice is just a few bugs, you can eradicate them by using a dab of isopropyl. However, if it is an infestation, your plant certainly needs treatment.

Insecticidal soap could come in handy as it is generally potent.

How Should I care for the Yellow Leaves?

Many times, a lot of growers ask about what to do with the yellow leaves when they start noticing them? You might have heard a lot of opinions, but the best practice is to wait till your plant leaves turn completely yellow and die before cutting them off.

A partially yellow leaf could still provide resources for the plants, so removing them too early can lot of harm.

The only condition to remove the yellow leaves as prompt as possible is if they have been affected by a disease. It will help curb the spread of that disease.

When your plant is in good care conditions, new healthy leaves are produced and, it will stand in for those leaves that are withering.

Some of these good care practices as we have stated include ensuring that the plants are well-nourished with a regular feeding plan.
