What to Do When Anthurium Leaves Turn Yellow? Detailed Explanation of Causes and Solutions

Yellowing anthurium leaves are a problem everyone encounters when growing flowers, so what causes anthurium leaves to turn yellow, and what should be done about it? Below, the editor will introduce the causes and solutions for yellowing anthurium leaves!

Overwatering

[Cause of yellowing] Watering too much or too often keeps the growing medium in the pot wet for long periods, or even waterlogged, causing some fibrous roots to rot, which hinders normal respiration and nutrient uptake, causing leaves to gradually turn yellow and drop.

[Solution] Water normally.

Uneven Fertilization

[Cause of yellowing] Too little fertilizer, or going a long time without repotting or changing the soil, leads to a lack of nitrogen and other nutrients in the soil, causing weak branches and leaves, with thin, yellow leaves. In addition, over-fertilizing can also cause new leaves to become thick and uneven, while old leaves develop dry tips and turn scorched yellow and drop.

[Solution] Fertilization should be stopped immediately, watering increased, and some of the old soil removed and replaced with fresh potting soil, followed by normal care.

Unsuitable Temperature

[Cause of yellowing] If the indoor temperature is too low in winter, the leaves will turn yellow; if the room temperature is too high, the plant transpires excessively, and the roots cannot supply enough water and nutrients, which will also cause the leaves to turn yellow.

[Solution] Keep the temperature in the greenhouse relatively stable.

Unsuitable Soil

[Cause of yellowing] In most areas of the north, the growing medium and water contain relatively high levels of salt and alkali. Because the medium lacks the soluble iron that the plant needs to absorb, the leaves gradually lose their green color and turn yellow.

[Solution] Treat the growing medium and the water used for watering with oxalic acid or similar.

Dry Air

[Cause of yellowing] When the air indoors is too dry in winter when growing flowers, leaf tips often dry out and turn yellow, or leaf margins become scorched, or scorched spots appear on the leaves and the edges curl.

[Solution] According to the growth characteristics of the anthurium, appropriately increase air humidity.

Excessive Shading

[Cause of yellowing] If the anthurium is kept in a shaded spot or a place with insufficient light for a long time, its growth will weaken, the leaves will be thin and yellow, and it will not bloom or will bloom very little.

[Solution] According to the growth characteristics of the anthurium, appropriately increase light intensity.

The above is an introduction to the causes of yellowing anthurium leaves and the corresponding measures, and we hope it helps you understand why anthurium leaves turn yellow.
