What about the yellowing of Anthurium andraeanum leaves? the causes and treatment of the yellowing of Anthurium andraeanum leaves.

Today, I would like to introduce Anthurium andraeanum, a plant suitable for keeping in the office. Can not raise at the beginning, easy to have a lot of situations, what should be done at this time? Next, let's learn about it with me.

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.

Classification of Anthurium andraeanum varieties

The first category is cut flowers with erect spikes of meat, represented by red crane taro.

The second type is potted flowers with curved fleshy panicles, represented by candles.

The third type is broad heart-shaped leaves, dark green and glossy, leaves with thick veins, silver and white, with beautiful patterns, represented by crystal candles. Cut flowers are widely cultivated, and there are more varieties of cut flowers.

The flowers of Anthurium andraeanum are good, but the edges of green leaves turn yellow. What is the reason and how should they be rescued?

① anthracnose

It is one of the common diseases of Anthurium andraeanum. The pathogen is Alternaria or Alternaria. The former is characterized by the formation of round brown disease spots along the veins of the leaves, and then the disease spots are linked together to form large disease spots with brown edges, and the disease finally dries up. The latter is similar to the former, there are black bad hairs on the conidial disk, and it will cause flower rot and form black necrotic spots on the inflorescence of the fleshy spike. High humidity is the main cause of the disease. The prevention and control methods are chemical control and strengthening cultivation management, always ventilating and transparent, avoiding watering or air-conditioning condensate splashing on the leaves, and removing diseased leaves in time.

② bacterial wilt

It is a bacterial disease caused by Xanthomonas aeruginosa, which can infect leaves and fleshy spikes. In the early stage of the disease, the leaves formed watery, translucent irregular spots, and then turned black, with a bright yellow edge and greenness around the spot. The pathogen can cause systematic infection, such as yellowing of old leaves, breaking of petiole and yellowing of vascular bundles. The method of prevention and control is to strengthen cultivation management, supplemented by chemical control, timely removal of diseased plant residues and burning. In the process of cultivation and management, man-made wounds and the use of ammonium nitrogen fertilizer should be reduced as much as possible. Generally, agricultural streptomycin or neophytomycin is sprayed at the initial stage of the disease.

What is the lack of yellowing in different parts?

(1) nitrogen deficiency

The basic leaves aging and falling off, the plants showed uniform light green to yellowish green, the leaves became smaller, the elongation of new shoots was slightly blocked, and accompanied by necrotic spots.

(2) phosphorus deficiency

The leaf margin of the old leaf at the base is yellow, the petiole is purplish red, the leaf is harder and smaller, and the plant is short.

(3) potassium deficiency

The basal old leaves are yellow between veins, while the young leaves of the plant are small and the leaves are light green or red. The edge of the flower is blue or for the red and orange varieties appear blue on the bud, and the light-colored flower species quickly appear glassy.

(4) calcium deficiency

The young leaves at the tip turned yellow and hooked, then died inward from the leaf tip and margin, and in severe cases, the stem top festered and necrotic.

(5) magnesium deficiency

The old leaves turn yellow along the veins, and the veins remain green.

(6) sulfur deficiency

The veins of the apical young leaves are yellowish green and the leaves are red or purple.

(7) Iron deficiency

The old leaves are green, the new leaves turn yellow, but the veins remain green, and then the leaves become more and more yellow, which is a typical symptom of iron deficiency.

What is the cause of Anthurium andraeanum flower fading (whitening)? Is there any way to improve it?

Anthurium andraeanum is not tolerant to strong light and should be cultivated in proper shade throughout the year. It should be properly shaded in spring, summer and autumn, especially 70% shading in summer. Direct sunlight will make the leaf temperature higher than the air temperature. If the leaf temperature is too high, there will be burns and scorched leaves, which will fade the bud and slow the leaf growth.

What is the optimum temperature of Anthurium andraeanum?

The optimum growth temperature of Anthurium andraeanum is 20-30 ℃, the highest temperature should not exceed 35 ℃, and the lowest temperature is 14 ℃. If it is lower than 10 ℃, it may cause freezing injury at any time.

What is the most suitable air relative humidity of Anthurium andraeanum?

The optimum air relative humidity is 70% Mel 80%, which should not be less than 50%, because keeping a high air humidity in the cultivation environment is the key to the success of Anthurium andraeanum cultivation. Therefore, foliar spraying should be carried out many times throughout the year.

Culture method of Anthurium andraeanum

1. Control the room temperature

The optimum temperature for the growth of Anthurium andraeanum is 18 ℃-- 28 ℃. The highest temperature should not exceed 35 ℃ and the lowest temperature is 14 ℃. Freezing injury may occur at any time when it is lower than 10 ℃. In summer, when the temperature is higher than 32 ℃, cooling measures should be taken, such as strengthening ventilation, spraying more water, proper shading and so on. Heating should be carried out in winter if the indoor temperature is lower than 14 ℃.

2. Maintain high air humidity

Anthurium andraeanum growth requires higher air humidity, generally not less than 50%, high temperature and high humidity will be more conducive to the growth of Anthurium andraeanum. When the temperature is below 20 ℃, keep the indoor natural environment; when the temperature is above 28 ℃, spray can be used to increase the relative humidity of leaves and indoor air, so as to create a high temperature and humidity growth environment of Anthurium andraeanum. However, in winter, even when the indoor temperature is high, it is not suitable to cool and moisturize too much, because the plant leaves are too wet at night will reduce the ability of cold resistance, easy to produce freezing damage.

3. Control the light.

When the light is too strong, it may cause discoloration, burns or scorching of the leaves. The success of light management is directly related to the quality of potted flowers and the number of flowers. Anthurium andraeanum is a shade-loving plant, so it is appropriate to put it indoors in a bright place with a certain amount of scattered light, and you should be careful not to put Anthurium andraeanum in an environment with strong direct sunlight.

4. Water and fertilizer management should be appropriate.

Anthurium andraeanum is a kind of flower which is sensitive to salt. The less salt in water, the better. It is best to use tap water. Fertilizers are often applied together with watering. A compound fertilizer with a nitrogen, phosphorus and potassium ratio of 1:1:1 is generally selected. After the compound fertilizer is dissolved in water, it is applied with a liquid fertilizer with a concentration of 1/1000. In spring and autumn, fertilizer and water are generally watered every 3 days. If the temperature is high, the dry and wet substrate in the basin can be irrigated once in 2-3 days; in summer, it can be irrigated once in 2 days; when the temperature is high, it can be watered once; in winter, it can be watered every 5-7 days. Anthurium andraeanum special fertilizer can also be used directly.

5. The matrix should be loose when changing the basin.

It can be mixed with peat soil, leaf bran and perlite at the ratio of 3:2:1.

6. Family maintenance

In summer, it can be placed on the shady side of the room or in the hall, where there is no direct sunlight outside, in the hall, or outside during the day, under the shade of trees, under flowers or in a cool place. It should be placed on the sunny side of the room in winter, inside the curtains at night, or closer to the heat source.
