What are the care methods for indoor flowering plants?
Indoor flowering plants generally have difficulty getting sunlight, so the methods used during cultivation will also differ. Indoor flowering plants can be considered by different varieties, and a cultivation method can be developed for each variety.

Clivia
Bulbous flowers:Flowers such as narcissus, daffodil, tulip and hyacinth (details) are all seasonal flowers with very short flowering periods, generally only 1 to 2 weeks. Indoors, they can be placed in a sunny, cooler spot; if the temperature is too high, they bloom quickly and the flowering period is shortened.
Orchid family flowers:Plants such as clivia, cymbidium, phalaenopsis, cattleya and dendrobium grow under tropical trees in nature, preferring humidity and shade, avoiding direct sunlight, and growing well in bright semi-shade. Therefore, at home, water should be sprayed frequently to increase air humidity. In winter, they can be given soft sunlight so they can carry out photosynthesis and gain nutrients. Orchid family flowers are susceptible to snails and scale insects; scale insects can be brushed off with a toothbrush. Take the common clivia as an example: it originates from the subtropical forests of South Africa, where it is warm as spring all year round, with an average minimum temperature not below 10°C and a maximum temperature not above 22°C. Clivia likes to grow in a warm, moist natural environment with moderate dryness and wetness, and the home should also create a similar environment. Clivia likes soft light and avoids scorching sun exposure. Clivia has fleshy roots and a certain drought resistance; overwatering can cause root rot. The water content of the potting soil for clivia should be at a state where it can be pinched into a ball by hand and loosens immediately with a gentle press.
Maranta family and fern plants:Maranta family plants such as peacock plant and purple-backed maranta, and ferns such as Boston fern, prefer a semi-shaded, warm, high-humidity environment with good drainage, and like bright light but cannot tolerate direct strong sunlight.
Cultivation methods for common indoor flowers
1. CliviaClivia has fleshy roots and fears waterlogging. Clivia leaves have a waxy layer, and in winter when temperatures are low, water transpiration and evaporation are reduced. Therefore, watering should not be excessive; it is enough to keep the potting soil moist. Never flood it with water, which can cause root rot and dead seedlings.
The most suitable growth temperature for clivia is 15°C to 25°C. In winter, clivia must be kept warm and protected from freezing. After the flower stem emerges, maintaining around 18°C is suitable. If the temperature is too high, the leaves and flower scape grow leggy, thin and long, the flowers are small and poor in quality, and the flowering period is short; if the temperature is too low, the flower stem will be short, affecting its ornamental value.
Clivia likes scattered light and avoids direct strong light. When cared for indoors in winter, the pot should be placed in a spot with sufficient light. Especially before flowering, there should be good light, which helps the flower buds develop. After flowering, appropriately lower the temperature, avoid strong light and maintain good ventilation, which helps prolong the flowering period.
2. Pothos
The cultivation methods and precautions for pothos should mainly be analyzed and done well from the following 5 aspects. As long as the requirements of the following 5 aspects are met, you will certainly grow very good pothos.
1. For indoor home pothos cultivation, loose, well-drained soil should be chosen for potting, and pothos is suitable for slightly acidic soil.
2. Temperature: The suitable temperature for growing pothos is 20 to 30 degrees, and it should not go below 15 degrees at the lowest; around 10 degrees it will freeze to death. Of course, most homes have growing temperature conditions suitable for pothos cultivation; just pay attention to keeping it warm in winter.
3. Light: It likes shade, so its light requirements are not strong. Therefore, during pothos cultivation, it is usually enough to place it indoors where it can see sunlight, so that it can better carry out photosynthesis, and then put it back indoors for display. Although pothos is very shade-tolerant, it cannot be kept in a dark place for a long time; at least about half a month, it should be exposed to strong light.
4. Water: Pothos cultivation should not involve too much watering; at most, spray water at its roots, as long as the soil is kept moist. In summer, watering can be appropriately increased; the principle is to keep the potting soil moist without water accumulation. In winter, watering should be restrained, once every two or three days is enough, and when indoor heating is on, watering can be appropriately increased; when the indoor temperature is too low, reduce watering.
5. Fertilizer: During the growing period of pothos, fertilization can be appropriately increased, and when fertilizing, spraying liquid fertilizer can be mainly used.
6. The difference between pothos cultivation methods and other plant cultivation methods is that because it has aerial roots on its stem nodes, it is very easy to keep alive, and propagation is generally carried out by cuttings. Especially at 15°C to 25°C, this is the stage when it grows fastest.
3. Phalaenopsis
Phalaenopsis is native to tropical Asia and is an epiphytic orchid; in the northern winter it needs to be cultivated in a high-temperature greenhouse. To create environmental conditions suitable for phalaenopsis growth, the main work is as follows:
1. Temperature: The suitable temperature for phalaenopsis growth is 25°C-30°C during the day; above 32°C is unfavorable for growth and flower bud differentiation. At night it is 18°C-20°C and must not be lower than 15°C. If a relatively high temperature is maintained, it is favorable for flowering.
2. Humidity: Phalaenopsis likes relatively high air humidity, and during the growing period it should be kept at 70%-80%. Therefore, water should often be sprayed into the surrounding space to increase humidity, but the moisture in the substrate must not be too much, otherwise root rot easily occurs; a slightly dry substrate is favorable for new root growth. 3. Light: According to weather conditions, open the shade net promptly every day to promote photosynthesis in phalaenopsis, and when the temperature is high or humidity is too great, open the skylight to let it ventilate and breathe.
4. Fertilization: For phalaenopsis fertilization, adhere to the principle of "light fertilizer applied frequently." A 1500-fold compound fertilizer can be mixed with 5000-fold boric acid for spray application, and afterward apply 1500-fold compound fertilizer once every other week. In addition, phalaenopsis has fleshy roots; to make its root system thick, the application of potassium fertilizer is relatively important.
4. Asparagus fern
It likes a warm, ventilated, semi-shaded and semi-moist environment, is not cold-tolerant, avoids direct sunlight, and is suitable for growing in sandy soil rich in humus and well drained.
The key to cultivating asparagus fern is watering. Too much watering and overly wet potting soil easily cause root rot and yellow leaf drop; too little watering and overly dry potting soil easily cause yellowing, scorching and dropping of leaf tips. Therefore, watering should usually depend on the weather, growth condition and potting soil condition. Correctly achieve: do not water when dry? No; water thoroughly when watering, and do not give "half water," that is, watering only moistens the soil surface while the lower potting soil remains dry.
In winter, with centralized indoor heating, the indoor air easily becomes dry, so pay attention to spraying the leaf surface with water more often to increase humidity, otherwise the leaves are very likely to scorch. Secondly, in a warm winter, asparagus fern will still continue to grow; in addition to water being indispensable, a little diluted fertilizer should also be appropriately applied, and dead branches and messy branches should be properly tidied and pruned.

Essential cultivation and care methods for summer flowers
Summer is hot and rainy; it is the peak growing season for some flowers and the dormancy period for others. To help flowers pass through this stage smoothly, management should be strengthened in aspects such as watering, shading and pest and disease control.First, summer temperatures are high and water evaporates quickly, so watering should be increased every day, such as watering once in the morning and once in the evening. At the same time, in high-temperature seasons, except for vigorously growing flowers such as jasmine and Chinese rose, fertilization is generally not suitable, especially for azaleas entering semi-dormancy and dormant bulbous flowers such as cyclamen and freesia.
Second, for some semi-shade and shade-loving flowers, high temperatures and direct sunlight must be avoided in summer. Shading measures should be taken, and water should be sprayed to lower the temperature. Even for plants with extremely strong drought tolerance such as cacti, when the temperature exceeds 38°C, there is still a risk of sunburn. For azaleas, in addition to daily watering, water should also be sprayed on the leaves and ground to retain moisture and lower temperature. However, summer often has heavy rainstorms. After potting soil accumulates water, nutrients are easily lost, so after rain the pot should be tilted to let the rainwater run out.
Finally, the stuffy hot summer is also a high-incidence season for pests and diseases. Dead and diseased branches and leaves should be removed promptly, supplemented by chemical control. For example, Chinese rose is prone to black spot and powdery mildew in summer; the former is treated with Bordeaux mixture, the latter with carbendazim, sprayed once every half month. Orchids are prone to anthracnose in the plum rain and high-temperature seasons; in addition to improving ventilation and light transmission conditions, when disease occurs, thiophanate can be used to spray once every 10 days.

Watering in summer flower management
Time to spray flowers in summer: before 9 a.m. and after 6 p.m. Pot flower watering roughly has the following situations and methods:
(1) Watering: in spring, summer and autumn, water before 10 a.m.; in winter, water at 2 p.m. Make sure the water temperature is close to the soil temperature, slightly higher in winter and slightly lower in summer. However, the water-soil temperature difference should not exceed about 5°C, and the amount of watering should be based on the degree of uniform moisture from the pot surface to the pot bottom. Watering must avoid "waist-cutting" (wet on top, dry below) and water accumulation (water collecting at the pot bottom). Also avoid soil and fertilizer loss through the pot hole, causing hollows in the pot center, which seriously affects the growth and development of pot flowers. When watering, note that flowers that like dryness can have watering controlled, keeping the potting soil slightly moist, with the surface soil showing a white sheen but not completely dried out. Flowers that like moisture should keep the potting soil moist often, with no white sheen on the surface soil, but there must be no long-term water accumulation.
(2) Supplemental watering: in dry weather, between 15:00-16:00, check the dryness and wetness of the potting soil and supplement an appropriate amount of water as needed, to the extent of keeping the potting soil moist. If the weather changes suddenly and water is needed under special circumstances, watering is not limited by time or frequency.
(3) Generous watering: for pot flowers during the vigorous growth and development period, to promote shoot growth, plant development, flower forcing and fruit strengthening, the amount of watering can be increased together with topdressing, keeping the surface soil without a white sheen and the leaves without wilting.
(4) Restrained watering: for pot flowers during the dormancy period or in low-temperature seasons, or to control seedling growth, promote flower bud formation, prevent leggy growth, and correct the phenomena of yellow leaves and bud drop caused by excessive water, the amount of watering should be appropriately controlled, keeping the potting soil moist, combined with loosening the soil to preserve moisture.
(5) Spraying: in dry spring and autumn seasons, in addition to normal watering and watering maintenance, water should be sprayed on the leaf surface and the flower-growing area to increase environmental humidity, prevent young leaves from scorching and flowers from withering early, and keep the plants fresh. Especially for southern flowers, more attention should be paid to environmental humidity. In summer, after rain when it suddenly clears or on stuffy hot evenings, water should be sprayed to lower temperature and prevent disease; whenever spraying water, the leaf surface should be sprayed clean to prevent residual water droplets and leaf dust from condensing into stains that are difficult to remove. Watering pot flowers is routine work. In the hot summer days mentioned above, turning on the air conditioner indoors can lower the temperature, but closing doors and windows blocks air circulation.
Therefore, keeping some "functionally complementary" flowers indoors can serve as an "air filter." Most flowers carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, and at night carry out respiration, absorbing oxygen and releasing carbon dioxide, while cacti, orostachys and similar plants do the opposite. Keeping "functionally complementary" flowers together in one room can both balance the indoor oxygen and carbon dioxide levels and keep indoor air fresh.

Summer flower management
It is said that narcissus, four o'clock flower, chrysanthemum and cockscomb can convert nitrogen oxides into protein, thereby removing toxicity. Spider plant, aloe and snake plant can absorb large amounts of indoor pollutants such as formaldehyde, eliminating and preventing indoor air pollution. Especially spider plant: place one pot in a room, and within 24 hours its leaves will "eat" harmful gases such as carbon monoxide in the indoor air, with an effect even exceeding that of an air filter; Milan, orchids, lilac, cactus and geranium can all effectively purify the air.
Camellia can resist harmful substances such as sulfur dioxide, and crape myrtle has relatively strong resistance to toxic gases such as indoor sulfur dioxide, hydrogen chloride, chlorine and hydrogen fluoride. Plum has monitoring ability for pollution in the environment such as sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehydes. Once sulfides appear in the environment, markings will appear on its leaves, and they may even turn yellow and drop.
It should be pointed out that these functions of plants have certain limits, and their effect increases with the number planted; it is impossible to rely entirely on indoor plants to satisfy this. Therefore, windows still need to be opened frequently to allow air convection.
In addition, a special reminder: in summer, do not turn the room into a "flower house." If all kinds of flowers and trees are placed too densely, indoor ventilation is limited, and the air will become as thin as at high altitude. Especially at night, most flowers release carbon dioxide and absorb oxygen, "competing for air" with people. Moreover, at night most rooms are closed, and the carbon dioxide respired by the soil in flower pots, the human body and pets will increase the carbon dioxide concentration, causing human oxygen deficiency, affecting health, and producing the opposite result. Methods should be used flexibly, step by step, and persistently.

Key management points in summer flower management
The stuffy hot summer is a high-incidence season for pests and diseases. Dead and diseased branches and leaves should be removed promptly, supplemented by chemical control. For example, Chinese rose is prone to black spot and powdery mildew in summer; the former is treated with Bordeaux mixture, the latter with carbendazim, sprayed once every half month. Orchids are prone to anthracnose in the plum rain and high-temperature seasons; in addition to improving ventilation and light transmission conditions, when disease occurs, thiophanate can be used to spray once every 10 days.
Jasmine: Summer is the full flowering period for jasmine. Spraying clear water on the leaf surface on sunny days can noticeably stimulate flowering. During this period, water and fertilizer should be sufficient to promote abundant flowers and lush leaves.
Orchids: Summer is the peak growing season for orchids, so the water and nutrients needed for growth must be ensured. Anthracnose easily occurs in the high-temperature plum rain season; in addition to maintaining a ventilated and light-transmitting environment, when disease occurs, thiophanate can be used to spray once every 10 days.
Azaleas: In summer, azaleas grow slowly and are in a semi-dormant state. Avoid scorching sun exposure and excessive fertilization, and shade them. Water 1 to 2 times daily, and spray water on the leaves and ground to retain moisture and lower temperature.
Tree peony: It avoids heat and fears moisture. In summer, place the plant in a ventilated, cool place and do not water too much; keeping the potting soil moist is enough to avoid root rot.
Chinese rose: It likes fertilizer and water, so a sufficient supply of water and fertilizer must be ensured. Apply decomposed bean cake water once every half month, and stop fertilizing in mid-July. In summer it is prone to black spot and powdery mildew; the former is treated with Bordeaux mixture, the latter with carbendazim, sprayed once every half month for control.
Milan: It likes light and heat, and grows vigorously in summer. Before and after flowering, apply diluted alum fertilizer water once every 10 days, and spray water on the leaf surface frequently.
