Anthurium Leaves Turning Yellow – Causes and Solutions

The Anthurium Plant is a common and quickly grown houseplant known for having colorful, mostly red leaves. Typically it grows well in moist soil that is warm during the day with a consistent humidity level. A few other varieties exist, one of which can grow well in pots and shade; however, the actual variety does not come from potted plants but rather from tropical rainforests. In other words, it is a popular houseplant typically used to provide a splash of color and interest to living areas during the colder months.

Causes for Anthurium Leaves Turning Yellow

1. Mineral Deficiency

A mineral deficiency is the most common cause of a plant’s yellowing leaves. Iron, Copper, and zinc are the most common minerals lacking in soil.

You can apply an iron or zinc supplement as directed by package instructions or talk to a horticulturalist if you think your plant may need one.

You can correct most mineral deficiencies with fertilizers. A soil test to determine the mineral level is beneficial, and your horticulturist would be happy to send one out if you are worried.

2. Fungus

Snails and slugs can eat your Anthurium leaves, causing them to turn yellow or brown. To get rid of them, you must follow the package’s directions.

Also, you can add some copper sulfate or equal parts bleach and water in a spray bottle. You can spray this regularly to keep the plant protected.

It can be a problem if you don’t protect your plants because it can cause the leaves to die or even kill them.

3. Over-Watering

If your Anthurium leaves are turning yellow, there is a perfect chance that you are over-watering them. It can be devastating because it involves the plant’s roots not getting enough water.

Anthurium plants like to have moist soil, but they don’t need to be overwatered because that can make their roots rot.

A good rule to follow is never to overwater an Anthurium plant. A good rule of thumb is to drain water from the saucer or pot you have about one month before re-watering.

4. Sunlight and Temperature

Sunlight causes your plant to be brown and burn leaves, while cold weather can cause it to lose color or change. It is crucial to ensure that you keep your plant’s environment at the right temperature and not too hot or too cold.

A horticulturist would be able to tell you if a problem exists, but it is best if you provide the right growing conditions in the first place.

Repotting it in a slightly bigger container may be necessary. The roots will spread, and the plant will get more light, which it likes. Be careful not to overwater your plant because this can kill your plant.

Keep the soil moist but not soggy by watering regularly. It is best done in the morning so that your watering has time to dry before nightfall. When you water, thoroughly soak the soil so that there are no dry spots on top or near your plant roots.

5. Heavy Metal Poisoning

Heavy metals such as Lead, Mercury, and Cadmium can cause Anthurium leaves to turn yellow. These metals are found in soil, water, and fossil fuels that are burned for energy generation. Plants that grow near a coal waste pile or a refinery may have high levels of heavy metals.

Plants cannot absorb the metals into their system because of the soil’s saturation level, and these heavy metals get left behind in the soil.

It means that the plants will absorb metals into their system. The symptoms of heavy metal poisoning include yellowing and light green, brown and black leaves.

Symptoms include:

  • Discoloration with discolored spots or streaks on the plant’s leaves looks like concentric rings.
  • Dead spots on your plant’s leaves. They look whitish and dry out.
  • A white powder was seen on your plant’s surface coatings of leaves.
  • The plant loses its vigor, or its growth has been dramatically reduced.

6. Poor Soil Quality

It is also important that your soil is of the right quality. The best soil is a premium, organic plant mix. It may lead to different problems, and you will have to consult with a horticulturist.

If you have poor quality soil, it can cause your plant to perform less well. The soil may also give off unusual smells as it breaks down, which can be unpleasant.

Good soil is rich in nutrients and beneficial microbes for plants. It is imperative because these microbes can help the plants produce essential oils, vitamins, and color for you so that they look healthy and beautiful.

7. Low Humidity

The plant will not get enough water and the roots can become compacted. The roots help the plant grow and absorb nutrients, air, and water. If there is not enough humidity, your plant may rot or weaken.

Ensure that your Anthurium has ample fresh soil and plenty of water. A slight dryness is delicate, but too much can cause dieback or even kill the whole plant.

Solutions for Anthurium Leaves Turning Yellow

1. Add Calcium to The Soil

Calcium is a primary mineral that is essential for the growth of plants. Its role in the soil is complex, and its benefits are many. It may be difficult for plants to get their share of Calcium even if you add Calcium to your fertilizer. You may have leached the Calcium in your soil away over time.

You can add Calcium to your plant’s soil by adding a tablespoon of lime for every gallon of water you use. The lime will provide a base for the Calcium to be held in the soil, allowing it to be used by the plants at their discretion.

This process should be done once or twice per month or as often as needed to maintain healthy growth and coloring in your Anthurium.

2. Add Aluminum Sulfate to the soil

Aluminum sulfate is a fantastic product. It is a fertilizer that adds essential nutrients to the soil so your plants can use it.

This product works because it provides plants with more than just one nutrient.

It provides a lot of different elements like carbon, nitrogen, sulfur, and phosphorus, in addition to the crucial aluminum sulfate element.

These nutrients are phosphates that give your plants the ability to use water efficiently and produce beautiful blooms for you to enjoy.

3. Add Copper to The Soil

Copper is a vital component of your plants. It helps with the absorption of nitrogen and the production of chlorophyll compounds.

It means that it helps the plant produce energy and will help it develop better pigment so it will not turn yellow or drop its leaves as quickly.

This product works by combining Copper with other essential elements like potassium, zinc, and iron. Adding these elements to your soil promotes nitrogen and chlorophyll production, promoting growth and healthy blooms.

These are great products to add to your soil because they will ensure that your plant has what it needs to remain beautiful.

4. Add Hydrogen Peroxide to The Soil

Hydrogen peroxide is a substance that you can purchase over the counter. It is used in many products, including make-up, home cleaning products, and reducing odors.

Add this substance to Your Soil in the form of slow-release products or as a spray. This product will help produce much-needed oxygen in the soil while improving growth and color production.

It is a fantastic product that you can use to help your plant maintain its beautiful chlorophyll coating and keep it looking healthy.

5. Garlic Fertilizer

Garlic is a well-known natural product that you can find in many different households. This substance is harvested and then added to a variety of products.

Some people like to eat it uncooked, and some use it for cooking. Others mix garlic with other ingredients and make balms, ointments, and salves for use on the skin.

All of these products work because they contain allicin, the main chemical in garlic. Allicin has a powerful effect on the plant and will help promote growth.

It will also keep your plant from getting yellowed or damaged by disease and pests. The chemical is combined with other elements like aerosolized ammonia, magnesium sulfate, and sodium bicarbonate which all work together to protect, promote and improve growth.

This product should be used as an amendment to your soil every two months, a maximum of four times per month.

This substance is excellent to use if you have a plant that seems to keep getting sick.

Since allicin can fight against most diseases, it may be more effective than the synthetic substances used in commercial pest control products. Garlic fertilizer is also excellent at keeping pests away because it has a strong odor which some insects find offensive.

One negative aspect of this product is that it can kill off beneficial soil microbes, so it should be used in small amounts or alternated with other soil amendments as much as possible.

6. Avoid Overwatering

When your plant needs more water or is in danger of overwatered, please turn off the faucet and give it a light mist. It will help prevent problems by not allowing the soil to become overly saturated.

One of the primary reasons that your plant might get yellowing is because it has too much water. It can happen if you are overwatering it or the plant is not getting enough water.

Overwatering can cause the roots to rot and cause your plant to be unable to absorb water properly. The problem can result in yellowing leaves, stunted growth, and possible death of your beautiful Anthurium.

7. Moderate Sunlight and Temperature

Expose them to the right amount of light. Plants do not like direct sunlight and will turn yellow if it is too hot or too cold. If you need to move them, be sure to do so during the day or at night when it is cooler outside.

It is best to keep them indoors and grow them where you can easily adjust them to fit your needs. Keep an eye on the temperature for your Anthurium to come out of winter and survive the summer season.

Growing Anthurium

This plant grows beautifully and can make a beautiful addition to your home. When you start your plant, it is best if you can grow it in conditions that will damage it less.

The ideal temperature range is between 50 and 85 degrees Fahrenheit. Use the Correct Soil and lighting in your home for Anthurium’s healthy growth and production of quality blooms.

When planting, you should be careful to take proper care of the root system of your Anthurium by not over watering or allowing anything to damage them.

If you want to ensure that you provide your plant with the best possible environment, then remember to change the soil completely each time you take it out.

Choose a spot outside so that it can receive good sunlight and ventilation. Plant your Anthurium in quality soil that is well balanced and free of contaminants like cottonseed hulls, pesticides, or chemical fertilizers.

When choosing soil, it is best to choose a mix of peat moss, leaf mold, or compost to help with drainage and aeration.

Yellow Anthurium plants can cause many problems, but you can quickly solve these problems with time, effort, and dedication.

When starting your new Anthurium, remember that it does not like to be exposed to direct sunlight for too long. Keeping this in mind will avoid significant stress on your plant.

If careful with these things, your plant can grow and develop appropriately without falling sick or losing its petals. The techniques listed above should help restore your plant to looking beautiful again.

Every plant is different, so what works for one may not work for another. If you have any questions or want to know more about the yellowing of your Anthurium, please feel free to write to me.
