What to Do When Anthurium Leaves Turn Yellow? Detailed Explanation of Causes and Solutions
In many places we can see the anthurium plant. Anthuriums are ornamental, with unique flowers and bright colors, and are very popular with many people. When growing anthuriums, one problem often comes up, and that is anthurium leaves turning yellow. Why does this happen? Below, the editor introduces the causes and solutions for anthurium leaves turning yellow.
Causes of Yellowing Leaves
1. Metabolism
If you notice anthurium leaves turning yellow, pay attention to the condition of the other leaves. If the leaves are fresh, tender yellow-green while the flowers are growing well, it means new leaves are growing, and old leaves turning yellow and dropping off is normal.
2. Unsuitable Soil
In most northern regions, the growing medium and water contain more salt and alkali. Because the medium lacks the soluble iron that the plant needs to absorb, the leaves will gradually lose their green color and turn yellow. Solution: treat the medium and the water used for watering with oxalic acid or similar.
3. Overwatering
When the new leaves of the anthurium turn yellow while the old leaves remain normal, this is generally because the plant is watered too much or too often, making the medium in the pot permanently too wet or even waterlogged, causing some fibrous roots to rot, which blocks normal respiration and nutrient uptake, causing the leaves to gradually turn yellow and drop off. Solution: water normally.
4. Dry Air
In winter, when the air indoors where plants are grown is overly dry, the leaf tips often dry out and turn yellow, or the leaf margins scorch, or the leaves develop scorched spots and curled edges. Solution: according to the growth characteristics of the anthurium, appropriately increase the air humidity.
5. Excessive Shading
If the anthurium is kept for a long time in a shaded spot or a place with insufficient light, 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 the light intensity.
6. Unsuitable Temperature
If the indoor temperature in winter is too low, 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 make the leaves turn yellow. Solution: keep the temperature in the greenhouse relatively stable.
7. Uneven Fertilizing
Fertilizing too little, or not repotting or changing the soil for a long time, causes a lack of nitrogen and other nutrients in the soil, resulting in weak branches and leaves and thin, yellow leaves. In addition, over-fertilizing will also cause new leaves to be thick and uneven, while the tips of old leaves dry out and turn scorched yellow and drop off. At this point, stop fertilizing immediately, increase watering, remove some of the old soil, replace it with new potting soil, and carry out normal care.
Solutions
1. When yellow leaves appear on the anthurium, check carefully for root rot, and if there is any rot, cut it off promptly.
2. Both overwatering and excessive light can easily cause yellow leaves and curled edges, so pay attention to adjusting the position of the pot.
3. Anthuriums have wide leaves and large flowers, so when misting, also wipe the flowers and leaves at the same time. Keeping them fresh and clean is the key to a beautiful plant.
4. Anthurium flowers are slightly toxic, and the toxin mainly comes from the sap. Never eat them by mistake, and wash your hands after each time you care for the plant.
5. Anthuriums are best grown outdoors, or in a well-ventilated corner that is not easily touched.
