Can azaleas also monitor ammonia? A practical care guide

Azalea, also known as yingshanhong, shanjuan and so on, is one of China's top ten famous flowers, with extremely high ornamental value. It also has the function of monitoring toxic gases. Now follow the editor of Huinong Network to learn about the azalea care guide.

1. Monitoring function

Azaleas have strong resistance to harmful gases such as ozone and sulfur dioxide, and can also absorb these harmful toxic gases, playing a role in purifying the air. They are also very sensitive to ammonia and can be used as a monitoring plant for it.

2. Care guide

(1) Light

Azaleas are long-day flowers. Even in midsummer, they should not be placed in overly shady places, but in ventilated and relatively cool spots, that is, in shaded outdoor areas. At the end of September and the beginning of October, when sunlight intensity weakens and the weather becomes cool, the shading time should be gradually shortened, and it is best to place them on a southeast-facing balcony in front of the house.

(2) Temperature

Move them out of the greenhouse in mid-to-late April, first placing them in a sheltered, sunny spot. In summer, provide shade, or place them under trees in light shade, avoiding direct strong sunlight. The suitable growing temperature is 15-25°C, with a maximum temperature of 32°C. Begin moving them indoors in mid-October. In winter, place them in a sunny spot and keep the room temperature at 5-10°C. The lowest temperature must not be below 5°C, otherwise growth will stop.

(3) Watering

In summer, water more and water frequently, because summer temperatures are high, sunlight is strong, and water evaporates quickly. Water thoroughly in the morning; in the evening, water as needed, and spray the leaves to keep the leaf surface clean and the environment humid.

(4) Fertilizing

At the end of winter and beginning of spring each year, it is best to apply some organic fertilizer to azaleas as a base fertilizer. After azaleas bloom from April to May, since the plants consume a large amount of nutrients during the flowering period, as leaf buds sprout and new shoots elongate, a topdressing can be applied about once every 15 days. After the dog days begin, most branch tips have stopped growing. This is a high-temperature season, physiological activity weakens, and topdressing can be stopped. After autumn, the climate gradually becomes cooler, and there are often continuous autumn rains. The temperature and humidity are suitable for azalea growth. At this time, the last topdressing can be applied. After winter begins, fertilizing is generally not advisable.

(5) Pruning

Pruning and shaping is an important measure in daily maintenance and management. It can regulate growth and development, thereby promoting vigorous growth. Daily pruning requires cutting off a few diseased branches and weak old branches, and combining this with the crown shape to remove some overly dense branches, increasing ventilation and light penetration, which is beneficial to plant growth.

(6) Pinching

During the bud stage, buds should be removed in time so that nutrients are supplied in a concentrated way, promoting larger flowers and brighter colors.

(7) Placement and display

Potted plants should not be placed on the ground. They should be placed on flower stands or inverted empty flower pots, with shade nets or curtains hung above, and this should be maintained.

The above is the editor of Huinong Network's summary of the azalea monitoring function and care guide. Have you learned it all? Azaleas not only bloom beautifully but also have a monitoring function. Friends who like growing flowers should not miss them.

Care guide for peace lily, which has environmental protection benefits

Peace lily is also known as white sail, spathe lily and silver bract lily. Its flower shape is beautiful and its ornamental value is high, making it a variety often grown by many flower lovers. However, peace lilies are easy to grow but difficult to care for. Now follow the editor of Huinong Network to take a look at the peace lily care guide.

1. Growth characteristics

Common varieties include Aida Qiao, Adito, Alpha, Domino, Gigante, Fiorinda, Petit, Prelude, White Princess, Stephen and so on. The peace lily plant is 30-40 cm tall, with oblong or broadly lanceolate leaves, dark green leaf color, obvious veins, and spherical berries.

2. Environmental protection benefits

Peace lilies can purify harmful substances in the air such as alcohol, acetone, trichloroethylene, benzene, toluene and ozone. According to estimates, each square meter of peace lily leaves can absorb 1.09 mg of formaldehyde and 3.53 mg of ammonia within 24 h. In addition, peace lilies have a high purifying effect on ozone and are suitable for placement next to kitchen gas stoves, where they can effectively remove cooking fumes and the particular smell of volatile substances.

3. Care guide

(1) Soil selection

Potted peace lilies should use loose soil with good drainage and aeration. It can be made by mixing leaf mold, peat soil and a small amount of perlite. Heavy clay soil should be avoided. The potting soil should preferably be replaced once every early spring.

(2) Light

Peace lilies are relatively shade-tolerant. As long as there is light, their growth needs can be met, so they can be grown year-round indoors in a spot with bright scattered light. In summer, 709 of the sunlight can be blocked. Direct strong light should be avoided, otherwise the leaves will turn yellow, and in severe cases sunscald will occur. In northern winter greenhouse cultivation, shading can be omitted or reduced. If the light is too dim for a long time, it is not easy for them to bloom.

(3) Temperature

For potted peace lilies, a room temperature of 22-28°C is most suitable for growth, and the overwintering temperature should be above 14°C.

(4) Watering

In daily care, attention should be paid to keeping the potting soil moist. In spring, summer and autumn, water frequently, and often use a fine-nozzle sprayer to spray water on the leaf surface to keep the air humid. In winter, watering should be controlled.

(5) Fertilizing

During the peak growing season, apply a dilute compound fertilizer or decomposed cake fertilizer water once every half month. In winter and autumn, fertilize as little as possible or stop fertilizing.

(6) Propagation

Peace lilies are commonly propagated by division. This is generally done in early spring when changing the soil. The rhizome at the base of the clump can be cut apart, and each small clump should retain at least 3 stems and buds, and more roots should be retained to help the new plants survive [Jishan Huayao].

(7) Pruning

When the peace lily's root system is too long or too dense, the old roots should be cut off in time and the long roots shortened. After the flowering period, the branches should be pruned along with the flowers to prevent the plant from drooping and affecting its appearance.

(8) Placement and display

The peace lily's flower stalks are upright and elegant. Potted plants are especially suitable for decorating living rooms and studies, elegant and distinctive. In addition, its flowers are also excellent decorative materials for flower baskets and flower arrangements.
