Why does Anthurium become yellow? how to deal with the yellowing of Anthurium andraeanum?

Why does Anthurium turn yellow? Anthurium develops a "yellow palm", in addition to the appearance may not be satisfactory, but also may cause Anthurium can not survive. Therefore, many friends who have just raised Anthurium andraeanum will ask why. In fact, there are many reasons for the yellowing of Anthurium andraeanum, which requires symptomatic treatment in order to fundamentally solve the problem.

Anthurium andraeanum, also known as Anzu flower, fire crane flower, etc., belongs to the genus Candle of Araceae. In the late 19th century, it was discovered and introduced and cultivated in Latin America, Colombia and Costa Rica, with a history of only more than one hundred years. The characteristic is to like warm and afraid of cold, wet and afraid of drought, like shade and avoid the sun. Its flowers are unique, there are flame inflorescences, bright and gorgeous color, rich colors, leaf-shaped bracts, common bracts are red, pink, white and so on, which is of great ornamental value.

Anthurium turns yellow for the following reasons.

1. Metabolism

If it is found that when the leaves of Anthurium andraeanum are yellow, we should pay attention to the situation of other leaves. If the leaves are fresh yellow-green, and the flowers are growing well, it means that new leaves are growing, and it is normal for old leaves to yellowing and falling.

2. Soil discomfort

There are more salt and alkali in the medium and water in most areas of the north. Due to the lack of soluble iron that plants need to absorb in the medium, the leaves will gradually lose green and turn yellow. Solution: use oxalic acid and other treatment media and water for watering flowers.

3. Overwatering

The new leaves of Anthurium andraeanum are yellow and the old leaves are normal. In general, too much water will make the medium in the basin too wet for a long time, or even stagnant water, causing some fibrous roots to rot, hindering normal breathing and absorbing nutrients, causing the leaves to turn yellow and fall off gradually. Solution: watering normally.

4. Air drying

When the air of indoor flower cultivation is too dry in winter, the leaf tip is often withered and yellowed, or the leaf edge is scorched, or the leaf has scorched spots, edge curling and so on. Solution: according to the growth characteristics of Anthurium andraeanum, increase the air humidity appropriately.

5. Excessive sunshade

If Anthurium andraeanum is placed in the shade or in a place with insufficient light for a long time, it will lead to weak growth, thin and yellow leaves, no flowering or rarely flowering. Solution: according to the growth characteristics of Anthurium andraeanum, increase the light intensity appropriately.

6. The temperature is not suitable

If the indoor temperature is too low in winter, the leaves will turn yellow; if the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are insufficient, the leaves will turn yellow. Solution: keep the temperature in the greenhouse relatively stable.

7. Uneven fertilization

Little fertilization, or no change of soil for a long time, lack of nitrogen and other nutrients in the soil led to thin branches and leaves, thin and yellow leaves. In addition, excessive fertilization will also lead to the thickening and uneven of new leaves, and the dry tip and scorched yellow of old leaves will fall off at the same time. At this time, we should immediately stop fertilization, increase watering, remove part of the old soil, replace it with new culture soil, and carry out normal management.

The treatment methods of Anthurium andraeanum yellowing are different due to different reasons. Therefore, when it is found that Anthurium andraeanum turns yellow, we must first confirm its etiology, and then prescribe the right medicine.
