How to grow potted Anthurium? Growing methods and precautions

  How to grow Anthurium? What are the growing methods and precautions for Anthurium? Friends who like growing Anthurium will first have such questions. Everyone should note that, among all flowers, Anthurium is very sensitive to salt. Anthurium has a unique appearance, with emerald-green leaves, and the fiery red spathe inflorescence sitting above them; the pairing of red and green looks so eye-catching. As for the question of how to grow Anthurium, many people are still at a loss. Below, the editor will introduce the growing methods for Anthurium!

  Flower pot:

  Pot material: In production, dark red plastic pots are mostly used. To coordinate with home decor, plastic flower pots in varied colors can be used for cultivation. When divided seedlings or tissue-cultured seedlings of Anthurium have 2 leaves, they can be transplanted into pots with a diameter of 9 cm, with 1 plant per pot. After they fill the pot, they can be planted in pots with a diameter of 16-20 cm.

  Soil:

  The soil for planting Anthurium must maintain good permeability and must not hold water. For home cultivation, you can choose to buy prepared potting soil at a garden store and add a small amount of ceramsite or dry bark to it (ceramsite: dry bark = 2:1). Disinfect the soil before planting (if you bought professional soil, this step can be skipped) to avoid Anthurium suffering from pests and diseases in the later growth stage.

  Temperature:

  The most suitable growth temperature for Anthurium is 14~35°C. In winter, when the temperature is below 10°C, Anthurium is easily frostbitten, so pay attention to raising the temperature in time. In summer, when the temperature is above 35°C, water should be sprinkled around the Anthurium to cool it down.

  Humidity:

  High temperature and high humidity are beneficial to the growth of Anthurium. Humidity is often related to temperature. When the indoor temperature is above 28°C, indoor humidity needs to be increased. A humidifier or sprinkling water can be used to add moisture; when the temperature is below 20°C, maintaining the indoor environmental humidity is enough. In winter, even if the indoor temperature is relatively high, it is not advisable to cool and moisturize too much. If the leaves of the plant are too wet at night, its cold resistance will be reduced, causing frostbite and making it unfavorable for overwintering.

  Watering:

  Water Anthurium according to the dryness of the potting soil. In spring and autumn, water once every 3 days; in summer, when the temperature is high, it is recommended to water once every 2 days, and spray the leaf surfaces at noon to increase or decrease humidity; in winter, watering once every 5~7 days is enough. When the weather is cold, watering should be chosen when the temperature is relatively high; watering between 9 a.m. and 4 p.m. is most suitable to avoid frostbite of the root system. When watering, note that watering should alternate between dry and wet, and avoid watering under severe water shortage, so as not to affect the growth and development of Anthurium.

  Anthurium likes moist to wet soil and relatively high air humidity. During the peak growth seasons of spring, summer, and autumn, keep the potting soil moist, and at the same time frequently spray its leaf surfaces and surroundings to increase air humidity. When the temperature drops to around 18°C in late autumn, gradually reduce water supply to keep the potting soil moist. Winter is the flowering season, so water cannot be lacking, but because the winter temperature is relatively low, watering should not be excessive; keeping the potting soil moist is enough. At the same time, because indoor air humidity is relatively low, attention should be paid to spraying its leaf surfaces and surroundings several times. If placed in an air-conditioned room, the number of sprays should be increased. When flowering, note that water should not be sprayed on the flowers.

  Fertilizing:

  Anthurium is a fertilizer-loving plant and has a relatively higher demand for magnesium fertilizer than other plants. It is recommended to buy a foliar fertilizer with a relatively high magnesium content at a flower shop, or choose a water-soluble compound fertilizer diluted into liquid fertilizer and spray it once a week during the growth period. When fertilizing, adhere to the principle of light fertilizer applied frequently, and it is better to apply less than too much.

  Anthurium likes fertilizer, but it is not tolerant of concentrated fertilizer. Do not fertilize when the temperature is relatively low in late autumn, winter, and early spring. In spring, after new leaves emerge, start topdressing, applying once every 10 days a mixed solution of 10 times diluted decomposed liquid fertilizer with an equal amount of 1000 times potassium dihydrogen phosphate solution, or 1000 times "Huaduoduo" general-purpose fertilizer. Stop fertilizing after the temperature drops to 15°C in late autumn.

  Pruning:

  During the growth period, promptly cut off withered yellow leaves and diseased leaves; when the leaves are too dense, appropriately thin out some old leaves. Cutting off old leaves can also promote the growth of new leaves.

  Pest and disease control:

  The most common pests of Anthurium are red spiders, nematodes, cabbage caterpillars, whiteflies, thrips, snails, and scale insects, among which red spiders, nematodes, and cabbage caterpillars are especially the main ones. However, Anthurium is relatively sensitive to insecticides. During home care, try to choose low-concentration pesticides to kill pests. Pay special attention that copper-containing pesticides and dimethoate, methamidophos, dichlorvos, malathion, parathion, etc. will be toxic to Anthurium, and it is recommended not to use them.

  Precautions:

  1. Insufficient sunlight makes flowering difficult

  Anthurium likes sunlight. If there is insufficient sunlight during the growth period, it is very difficult for it to flower, but it is also not suitable to let sunlight shine directly on it, as leaf scorch will occur. The best method is to place it in a bright shaded place, where it can avoid the blazing rays of strong light while still receiving diffused sunlight.

  2. Unsuitable temperature makes it hard to keep alive

  When growing Anthurium, attention should be paid to temperature control. Its suitable growth temperature is 18°C---28°C. The maximum temperature should not exceed 35°C, and the minimum temperature is 14°C. Below 10°C, frost damage may occur at any time, so in summer when the temperature is high, pay attention to ventilation and sprinkling water, and in winter, greenhouse cultivation should be carried out.

  3. Proper humidity gives a beautiful posture

  When growing Anthurium, attention should be paid to moisturizing. If the humidity required during the growth period of Anthurium can be correctly controlled, Anthurium can grow robustly, with fiery red petals, exceptionally vivid, and a very graceful posture.

  4. For potting soil, a culture soil mixed with 6 parts leaf mold, 3 parts river sand (or perlite), and 1 part decomposed cow manure or chicken manure and other organic fertilizer is best. When potting and planting, fill the bottom of the pot with soft crushed brick pieces and other materials to a depth of 1/4 to 1/3, so as to facilitate drainage of the potting soil.
