What to Do When Anthurium Leaves Turn Yellow? Cause Analysis and Solutions

Anthurium is a perennial herbaceous flowering plant. Its flowers resemble those of the peace lily (Spathiphyllum), but are pink or scarlet, and the flowering period can last as long as 2-4 months. Its leaves are solitary, heart-shaped or ovate, dark green in color with a certain gloss. It can serve as both a foliage plant and a flowering plant, with considerable development prospects. However, yellowing leaves are prone to occur during cultivation, and this condition is generally caused by improper cultivation methods. Below, Qinnong Web introduces the causes and solutions for yellowing leaves on Anthurium.

1. Improper Watering

If the young leaves at the top of the Anthurium turn pale yellow, the older leaves also gradually turn yellow, and the new shoots wither, this condition is caused by overwatering, which makes the potting soil too moist, the soil not breathable, leading to root rot, and then causing the leaves to turn yellow.

Solution:

When watering, control the amount of water properly and avoid water accumulation. You can loosen the soil around the Anthurium at intervals, which helps the soil breathe. If the color of the top leaves of the Anthurium is normal, but the lower leaves gradually turn yellow and withered from the bottom upward until they drop, this is caused by prolonged drought in the potting soil. In this case, moderate watering is needed, and remember to water thoroughly to keep the soil moist.

2. Insufficient Light

Anthurium is a plant that needs a certain amount of light. Apart from providing some shade in summer when the light is too strong, it can receive full light in winter, and at other times care should be taken to let it receive plenty of diffused light. If the Anthurium is placed in a place without sunlight for a long time or exposed to the sun for a long time, it is also very easy to cause yellow leaves.

3. Potting Soil Problems

When the leaves of the Anthurium appear thin and yellow, it may be due to insufficient fertilizer, an unsuitable pot size, or not having repotted for a long time. Therefore, choose a suitable pot, gradually increase fertilizer during the growth process to maintain sufficient nutrients, and also repot in a timely manner. The soil should preferably be loose, breathable, and contain a certain amount of nutrients. Place a few bricks at the bottom of the pot, which is more conducive to drainage.

4. Fertilizer Requirements

If there is a long-term lack of fertilizer supply and only plain water is used for maintenance, the leaves will turn yellow due to insufficient nutrients. However, if the leaves are uneven and bumpy, the new leaves are very thick, and the old leaves begin to turn yellow, then fertilizer burn has occurred. At this point, stop fertilizing and water more. You can also put some vegetable seeds in the pot to help absorb the fertilizer and ensure the plant returns to a normal state.

The above is what Qinnong Web has compiled regarding the causes and solutions for yellowing leaves on Anthurium. Anthurium represents "passion, boldness, and joy" and can be used on festive occasions such as celebrations and ceremonies. However, Anthurium is a plant of the Araceae family and therefore has a certain toxicity. Be careful not to touch Anthurium with your skin frequently, but Anthurium itself does not emit a toxic odor, so it can be safely grown indoors at home.
