Who knows how to raise flowers with "red sun as the head" …

This is good luck. This is a kind of bromeliad plant.

temperature

Hongyun is native to tropical South America, the suitable temperature is 15℃ to 22℃, and the lowest temperature in winter should not be lower than 10℃, otherwise the plants will be frozen and their leaves will turn yellow, which will affect their healthy growth.

illuminate

Lighting is very important to make the leaves on Hongyun's head bloom brightly and regularly. There should be at least 4 to 5 hours of direct sunlight every day in winter. In rainy days, you can use lights to increase the light. Seedling pots should be placed in the shade in summer, and shading nets can be set up according to the needs of indoor cultivation.

land

Hongyun is suitable for the growth of loose, fertile and humus-rich soil. For home cultivation, 2 parts of peat soil can be mixed with 1 part of fine sand to prepare culture soil.

fertilizer

Hongyuntou is a flowering season in winter, so it needs sufficient fertilizer. Usually, rare organic liquid fertilizers are applied once every two weeks, such as bean cake, sesame sauce residue soaking solution (concentration is 20%), soybean soaking solution or fermented rice washing water.

water

Hongyun likes a humid environment. It is enough to keep the basin moist on weekdays, and generally do not water it in rainy days. Watering needs to be done before noon, or in the morning and evening of summer, but it must be poured in the leaf cup, not just in the pot soil. Keep the leaves clean at night. To humidify, it is necessary to replenish water in the growing environment, such as sprinkling water on the ground or starting the humidifier.

Watering depends on the amount of water in the leaf cup. There should be enough water in the leaf cup and the water quality should be clean. It can also be watered with fat water, but fresh water must be replaced in a week or so, otherwise the plant core will rot easily and smell bad.

It is best to use dry water instead of tap water for family feeding. Pineapple is a kind of flower that can enjoy flowers and leaves. It is best to spray clear water on the leaves once a day, which can remove dust and make the leaves bright, which is also beneficial to photosynthesis and promote the healthy growth of plants.

Eliminate pests and diseases

In the environment of high temperature, high humidity and poor ventilation, Hongyun is prone to diseases and insect pests, such as soot disease, red spider, scale insects and so on. If diseases are found, carbendazim can be sprayed in time, and omethoate can also be sprayed on pests. No matter what liquid medicine is sprayed, it must be carried out outdoors to prevent indoor environment from being polluted. In addition, you can also buy bactericidal and insecticidal tablets from the flower market and bury them in the pot soil to eradicate pests and diseases.

Erythema is a symptom of brown spot disease, and it needs to be sprayed with carbendazim, dipyridamole, Aimei and agricultural streptomycin in time to prevent it.

This is because the timing of spraying water is too late, so don't spray water after evening, which is easy to breed germs and can't leave moisture on the leaves at night.
