Indoor greening decoration refers to using ornamental materials, mainly indoor foliage plants, according to the characteristics of the indoor environment, and combining the needs of people's lives to beautify and decorate the objects and places used.
NO.1 Rhododendron: its leaves are covered with fine hairs, which can regulate moisture and absorb dust, making it suitable for growing in households in large cities with many people, many cars and polluted air. More importantly, rhododendron can detect most toxic gases indoors. When there is sulfur dioxide or nitric oxide in the air, spots will appear on the rhododendron leaves, and the edges will begin to wither.
NO.2 Aloe: purifying harmful gases in the air such as formaldehyde, sulfur dioxide and carbon monoxide is its strong point, and it can also kill bacteria in the air and absorb dust. When there are too many harmful gases, brown spots will appear on the aloe leaves, serving as a warning. In addition, the juice of aloe leaves can also be applied to scalded areas, which can have a bactericidal and anti-inflammatory effect. Aloe is a flower that is very suitable for growing in large-city households.
NO.3 Petunia: it is relatively sensitive to fluoride and can be used as an indicator or detection plant. It can also secrete bactericides, kill certain bacteria in the air, inhibit the growth of diphtheria, tuberculosis, dysentery and typhoid bacteria, and keep indoor air clean and hygienic. In addition, its flowers are large and brightly colored, and it grows vigorously. It can be placed in the kitchen, living room, balcony and other places, making it a superior flower for household growing.
NO.4 Rieger begonia: it can not only absorb formaldehyde and purify the air, but also be used to monitor the content of carbon dioxide and traditional air pollutants in the home, especially in the kitchen. At the same time, it has a long flowering period, rich flower colors, emerald green branches and leaves, and brilliant flowers. It is an excellent variety for beautifying the indoor environment in winter, and is especially suitable for placing on the dining table, allowing you to enjoy beautiful scenery while enjoying delicious food.
These eco-friendly flowers and plants that can forecast toxic gases and have gorgeous flowers can all be bought at Wuhan East Lake Flower and Tree City, where there are dozens of shops for you to choose from!
Growing flowers and plants on the rooftop
Rooftop greening has become a beautiful scenery in increasingly crowded cities. The crowded urban population and limited space have inspired the concept of rooftop greening. The cultivation of rooftop plants, rockeries and courtyard design beautify the environment on the one hand and give people more places for leisure; on the other hand, they are also of great help to improving urban air quality and greening.However, due to special actual conditions, rooftop garden greening has high construction requirements. It not only requires careful design, strict waterproofing and high costs, which makes many citizens hesitate even though they want to beautify and green their rooftops.
Growing flowers and plants on the rooftop
Rooftop greening can not only add green to the city, but also reduce the radiant heat of building roofs; in addition, plants can absorb harmful substances such as sulfur dioxide and dust above the city, purifying the high-altitude urban air.
However, because rooftop greening has high requirements and citizens happen to lack the corresponding technology, many citizens who want to carry out rooftop greening do not dare to try it easily. According to professionals, rooftop greening is affected by factors such as house structure and load-bearing capacity, and has certain technical requirements.
According to estimates, when planting turf on a rooftop, the soil thickness should be between 15 and 20 cm, while the roof load-bearing capacity must reach nearly 200 kg.
Growing flowers and plants on the rooftop
The roof platform is located on the top floor of a building, with an open position, light air pollution, little dust and good sunlight transparency. Therefore, it can inhibit excessive elongation of stems, promote the formation of anthocyanins, and make flowers grow robustly, with compact plant shapes, dark green leaves at night, and especially brilliant and colorful flowers and flower postures.
At the same time, the distribution of light intensity and duration across the entire roof surface is relatively even, and it has the characteristic of receiving light in all directions, providing superior growing conditions for light-loving plants and flowers. However, the rooftop in midsummer is scorching like fire, with intense sun exposure, so appropriate shading is needed to ease the strong sunlight and prevent sunburn on flower leaves.
Growing flowers and plants on the rooftop
In addition, the temperature on the rooftop platform changes relatively dramatically. At noon in summer, with the scorching sun overhead, many plants and flowers find the summer heat hard to endure. At night, cool wind blows, which is also unfavorable to the growth of flowers and trees. In winter, because the rooftop is windy, temperatures both day and night are generally lower than at ground level, and the temperature decreases as the floor level rises.
Growing flowers and plants on the rooftop
Some flowers grown at ground level can overwinter, but on high-rise rooftops it is very difficult for them to overwinter, and they suffer frost damage. Therefore, when growing flowers on a rooftop platform, in addition to choosing appropriately stress-resistant sun-loving flowers for planting and cultivation, strict protective measures must be taken during the overwintering months.

Home flower growing - overwintering management of flowers after the Start of Winter
1.Controlling water and fertilizer, keeping warm, and pruning are keyAfter the Start of Winter among the 24 solar terms, the weather will get colder and colder, and various flowers will also shift from the vigorous growth period to a slow or dormant period. How to let the flowers and plants at home pass the winter safely has once again become a topic of concern for urban farmers. "Winter is the season with a relatively high flower mortality rate. At this time, key management should be carried out in aspects such as water and fertilizer, temperature and diseases." said a teacher from an academy of agricultural sciences.

It is reported that according to different habits, flowers can be roughly divided into cold-fearing and cold-tolerant types. Cold-tolerant plants such as Chinese rose can overwinter safely even if placed outdoors, while cold-fearing plants such as the money tree must be moved indoors.
However, because evaporation is relatively low in winter for most flowers, the frequency and amount of watering need to be reduced. For fertilizing, low-concentration fertilizer is suitable. For most foliage plants, nitrogen fertilizer should be stopped, and some low-concentration potassium fertilizer should be appropriately applied to increase the cold resistance of the flowers.

2.Succulents: treat summer-type and winter-type differently
Most succulents are distributed in dry tropical and subtropical environments. They like high temperatures and light, and fear humid and low-temperature weather. However, according to their living habits, succulents are also divided into winter-type, summer-type and spring-autumn type. The so-called winter-type means dormancy in summer and growth in winter. Summer-type means dormancy in winter and growth in summer.
"When winter comes, winter-type and summer-type succulents should be treated differently. Summer-type ones should have water controlled, while for winter-type ones, do not be reluctant to water them." said succulent cultivation expert Xiao Pei. It is reported that from November to December, succulents should mainly focus on cold protection and heat preservation and increasing light. Summer-type varieties grown in greenhouses should be watered in the evening, and the amount of watering should be controlled. For living stones and conophytums whose flowering period has ended, division of offsets can be carried out at this time.

When the temperature drops below zero, varieties with poor cold tolerance should stop being watered, and heat preservation work should be done well. At the same time, flower pots should be rotated at irregular intervals as much as possible so that the plants receive sunlight evenly. When light is insufficient, artificial light sources can be used as a supplement. When late January arrives, winter-type varieties will be in a period of vigorous growth, so do not be reluctant to water them.
Netizen Lao Tu has a good method for getting summer-type succulents through winter, and it can be done with just one plastic bag. When the temperature is below 5°C, cover them with a plastic bag or a disposable cup, and cut off water to keep the soil dry, until April of the following year when the cover is opened again.

3.Hydroponic plants overwintering requires controlling water and fertilizer
Hydroponic plants are deeply loved by many citizens because they are clean and simple to manage. However, winter is the season when hydroponic plants are most likely to die. In areas south of the Yangtze River, there is no heating indoors, and most plants are in a dormant state. At this time, hydroponic plants should have their water changed as little as possible or not at all. When the water level is too low, a suitable amount of water can be added, generally controlled at one third of the root system.
Home flower growing - overwintering management of flowers after the Start of Winter. There is a saying that "applying nutrient solution to dormant hydroponic plants is like poisoning them." Although it sounds a bit exaggerated, fertilizing in winter indeed relates to the life and death of hydroponic plants. In winter, the use of nutrient solution needs to be stopped, otherwise root rot and leaf drop are very likely, or even the death of the whole plant. However, if the growing environment of hydroponic plants can be kept above 15°C, then normal care methods can be followed, and the plants will not only not go dormant but will also grow vigorously.

4.Bougainvillea: paying attention to the timing of moving indoors and outdoors is key
Bougainvillea has become a "new favorite" among urban farmer group members because of its large flowers, abundant quantity and brilliant color. However, the difficulty of overwintering also gives many people a headache. Because winter temperatures in the Hangzhou area can reach minus 6°C to minus 8°C, bougainvillea cannot overwinter in the open ground.
Home flower growing - overwintering management of flowers after the Start of Winter. "Generally, when the minimum temperature is 8°C (in Hangzhou, generally around late November), bougainvillea needs to be placed indoors or in an enclosed balcony to overwinter." said a netizen from the Urban Farmer group. At this time, it should first be pruned, retaining the main branches and some flowering branches, placed in a sunny spot, and kept as sheltered from wind as possible. Under direct sunlight, ventilation should be carried out in time to prevent the ambient temperature from being too high.
Home flower growing - overwintering management of flowers after the Start of Winter
In the Hangzhou area, after bougainvillea is moved indoors or onto a balcony, the watering frequency can be once a week, and watering in the mid-to-late afternoon or in the evening is generally most suitable. Moving it outdoors should be done around late April, and at the same time attention should be paid to pruning it, removing dead branches and useless branches, to beautify the plant shape. Although in late March, as temperatures rise, new buds will sprout on bougainvillea and flower buds will also differentiate, if it is moved outdoors at this time, it is easy to cause the flower buds to freeze, resulting in the phenomenon of no flowering in May.
