What to do when anthurium leaves turn yellow? Let me show you how to solve it easily
Anthurium, also known as flamingo flower, is deeply loved by everyone because of its broad green leaves, spadix like a Buddha's flame, and petals red as fire, full of auspicious and festive meaning. Yellowing anthurium leaves is a problem everyone encounters when growing flowers, so what are the causes of yellowing anthurium leaves?
Causes of yellowing anthurium leaves
☆--Cause 1 of yellowing anthurium leaves: overwatering:
Watering too much and too often keeps the potting medium constantly too wet, or even waterlogged, causing some fibrous roots to rot, hindering normal respiration and nutrient uptake, and causing leaves to gradually turn yellow and drop. Preventive measure: water normally.
☆--Cause 2 of yellowing anthurium leaves: uneven fertilisation:
Too little fertiliser, or going a long time without repotting or changing the soil, means the soil lacks nitrogen and other nutrients, resulting in weak branches and leaves, with thin, yellow leaves. In addition, excessive fertilisation can also cause new leaves to be thick and uneven, while old leaves dry at the tips, turn scorched yellow and drop. At this point, stop fertilising immediately, increase watering, remove some of the old soil, replace it with fresh potting soil, and return to normal care.
☆--Cause 3 of yellowing anthurium leaves: unsuitable temperature:
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 make the leaves turn yellow. Preventive measure: keep the greenhouse temperature relatively stable.
☆--Cause 4 of yellowing anthurium leaves: unsuitable soil:
In most areas of the north, the 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 colour and turn yellow. Preventive measure: treat the medium and the water used for watering with oxalic acid or similar.
☆--Cause 5 of yellowing anthurium leaves: dry air:
When the air indoors is too dry in winter when growing flowers, leaf tips often dry out and turn yellow, or leaf edges become scorched, or leaves develop scorched spots and curled edges. Preventive measure: according to the growth characteristics of anthurium, appropriately increase air humidity.
☆--Cause 6 of yellowing anthurium leaves: excessive shading:
If 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. Preventive measure: according to the growth characteristics of anthurium, appropriately increase light intensity.
Anthurium likes a warm, moist environment with good drainage. A sandy, gravelly soil is suitable, and the medium should be kept moist. In summer, water should be sprayed 2-3 times a day, and the temperature should be kept between 14-35°C. It dislikes direct sunlight and drought. Anthurium has a long flowering period: as a potted plant it lasts 4-5 months, and as a cut flower kept in water in a vase it can also last 1.5 months, giving it very high ornamental value. So, in the process of growing anthurium, you will always run into the problem of yellowing leaves. How should we prevent anthurium leaves from turning yellow?
How to prevent anthurium leaves from turning yellow
☆--1. Anthurium is a tropical flower that likes high temperatures and fears the cold, likes shade and avoids sun, and likes moisture and avoids drought. Usually, take care not to expose it to strong sun, and do not place it in an environment with strong direct sunlight. What to do when anthurium leaves turn yellow? But it also cannot be kept in a dim indoor spot for a long time; it should be placed in a bright place with scattered light.
☆--2. Anthurium's watering requirement is: water only after the soil has dried out, and water thoroughly. I don't know how long you have had your anthurium; the yellowing leaves may be because you watered too often, watering again before the soil had dried out.
In addition, anthurium needs fertilising about every two months, and a lack of fertiliser can also make the leaves turn yellow. When fertilising, it is best to use a special anthurium fertiliser; when you buy an anthurium, a reputable supplier will include fertiliser. Anthurium requires a growing temperature of no less than 15°C, otherwise the leaves and flower stems easily turn black.
☆--3. Environmental prevention: strengthen control of the greenhouse temperature (the ideal breeding condition for bacteria is around 30°C), the sanitary environment, and the movement of personnel and tools in the production area.
☆--4. Fertiliser prevention: during plant growth, try not to use nitrogen fertiliser in the high-NH4 form. Remove or isolate diseased plants.
Leaf blight nematode disease is caused by infection by nematodes of the genus Aphelenchoides, mainly infecting the roots and leaves. The symptoms are necrotic spots or brown spots forming along the leaf veins, root swelling, and finally the whole leaf drying up.
The main control methods are strengthening seedling quarantine, selecting robust seedlings, and properly disinfecting the growing medium.
☆--5. Soil pH control. Anthurium is a flower variety relatively sensitive to salt, so the medium pH should be kept between 5.2-6.1, which is what to do when anthurium leaves turn yellow and is most suitable for anthurium growth. If the pH value is too low, the flower stems become shorter, which reduces the ornamental value.
Tap water is suitable for planting anthurium, but it is expensive; natural rainwater is the best water source for anthurium cultivation. Potted anthurium has different water requirements at different stages of growth and development.
☆--6. Care details. The yellowing leaf phenomenon in anthurium is mainly root rot caused by too low a temperature; too much fertiliser and water, because excessive fertiliser application disrupts the metabolism of the flamingo flower; overwatering can also turn anthurium leaves yellow and affect the ornamental value; too much light will turn anthurium leaves yellow and make them lose their lustre, and will also cause slow growth, short petioles, small leaves, and curling that does not open; vigorous growth without flowering is generally caused by a placement spot that is too dark and too much nitrogen fertiliser.
What to do when anthurium leaves turn yellow? How to prevent anthurium leaves from turning yellow? Now everyone should have a clear idea. Growing anthurium is actually relatively simple. Even if problems such as yellow leaves appear, as long as we observe carefully we can find out what is causing them, and taking targeted measures will naturally solve them and let you grow a beautiful pot of anthurium.
