Anthurium plant has beautiful leaves and flowers. They look so good but if your anthurium plant leaves are turning into yellow color. Do not worry anthurium leaves turning yellow is a common problem and we are here to help you.

Overwatering, low humidity, excess of direct light, etc are the main reasons for yellow leaves.

In this article, we will help you to identify the reasons that cause anthurium leaves turning yellow from bright green.

Here is what you can do?

In tropical regions, anthuriums grow with other plants. Mostly they grow on other big trees, on their branches rather than directly into the soil. If you grow them in the perfect growing conditions, they will stay healthy for years. Growing them at home is an easy process, you just need some experience with tropical plants first.

When you see the leaves of your plant are turning into yellow color this means the plant is not in good condition. This is the first sign of its bad health. Here you need to act fast to identify and remove the cause that turns anthurium leaves yellow.

Causes of yellow leaves

Environmental stress

This means your plant is under the stress. Two main factors are mostly responsible for yellow leaves over-watering and excess light. According to biology scientists when a tropical plant that does not need direct bright light receives excess light. Then the green pigment in the leaves which allows plants to absorb energy from a light break down. This reduces the energy absorption rate which results in yellow or brown color leaves.

Lack of nutrition, Low or no humidity, lack of water is other forms of environmental stress which trigger yellow leaves.

  1. Over-watering

Most of the time overwatering is the main cause of yellow leaves. Anthurium plants like to live in moist soil, not wet soil. This requires continuous monitoring of the plant. keep an eye on the soil condition. If you do not have enough time for your plant but you want it in your home garden then you can use self-watering pots.

Overwatering leads to the root rot which is a deadly condition for house plants and if not detected early the plant will die in a few days. Also, this blocks the water absorption which causes yellow or brown leaves in just 2 days.

Potting soil should not be dry, it should be moist all the time. Always check moisture in the soil before watering your plant.

  1. Low Humidity Level

Anthurium plant is a tropical rain forest plant.  This means the Anthurium plant is native of those forests where humidity levels are more than 90%. So, you need to grow your plant in a high humid place. The problem is we do not have such places at our home unless you are living in a high humid area. A bathroom is a place where humidity levels are 100% but we cannot grow plants in our bathroom.  If you are sure that you are watering your plant carefully then the low humidity levels are the issue.

Indoor humidity levels are extremely low in the winter season when we close all the doors and start our heating system.

The following are the best ways of increasing humidity level

  1. Use a humidity tray with pebbles
  2. Buy a humidifier
  3. Keep your plants together
  4. Moist your plant from the above.
  1. Poor Nutrition

Anthurium needs fertilizer once in every month. You need to give it proper nutrition mainly rich in phosphorous. We are using bone meal fertilizer, a rich source of phosphorous. Phosphorous fertilizers are required for blooms.

Always give less fertilizer than the recommended dose on the package. The reason is simple, houseplants do not need a heavy supply of nutrients like outdoor plants.

If you are giving more fertilizers than the above-mentioned quantity stops it right now. Take out the plant, clean the pot, remove the build-ups of fertilizer and repot it in the same container.

Remember the higher dosage of fertilizers can damage your plant permanently which leads to its death. Be careful while fertilizing your indoor house plants.

  1. Poor Quality of Soil

Soil that does not have good darning properties is also a problem for the plant to grow. Heavy soil holds a high amount of water in it which results in fungus and root rot. Moreover, heavy or tightly packed soil does not allow the excess water to drain easily.

If you are not sure about the soil, add some of the peat moss or perlite into the soil. Make it 60- 40 ratio (60% soil and 40 % perlite). If you feel it needs to be repotted in a big container do it without any delay.

  1. Excess of Light

Too much sunlight is the common cause of anthurium leaves turning yellow. Houseplants do not like direct sunlight. They need bright light but not direct light on them. This is the reason people use Grow Lights in their indoor gardens. You can control the intensity of the grow lights plus spectrum according to your plant health.

Too little light also causes problems, your plant needs bright light to bloom. Insufficient light changes the color of leaves from bright green to dark green.

Measure the light-emitting on the plant by using the light meter. Extreme light makes leaves edges brown and sometimes you see burn marks on them. If this the satiation please change the location of your plant immediately.

  1. Temperature

20 to 30 degrees Celsius is the best temperature range for the anthurium plant. Maintain the temperature in the suggested range. Normally we have our inside home temperature suitable for the tropical plants. Remember the temperature in the garage is high in summer and low in winters than the suitable temperature. So do not put your plant there for a long time.

Quick Summary

Maintain the constant temperature between 20 to 30 degrees Celsius

Soil should be well-drained

Use slow-releasing fertilizer

Bright indirect light is best

Grow in a high humid area

Remove dead leaves immediately

Do not let the soil dry completely

Repot when needed

Final Words: Anthurium plants are delicate tropical rain forest plants. They are easy to grow and do not required much maintenance. We hope you find the reason responsible for your anthurium yellow leaves.
