20 kinds of flowers, the sun never dies, the heat never dies, and the weather blooms crazily!

The limit temperature of bougainvillea: 37 degrees indoors, still blooming.

Bougainvillea is one of the most heat-resistant large plants in South China. In summer in Guangdong, Fujian, the indoor temperature is 37 degrees, and flowers can still bloom. If it can be cultivated in the open air and planted in the ground, the environment will be more transparent and heat resistance will be stronger.

Summer maintenance skills:

The temperature is high in summer, so water bougainvillea in time. Before, I taught the university to use water control to promote flowers, and then watered them thoroughly after the leaves drooped slightly to stimulate the third girl to blossom. It can also be used in summer, but it should be watered in time and not delayed for too long to prevent water shortage and leaf falling off.

If you don't use water control to urge flowers, you can also water Huaduoduo No.2 when there are no flowers (before and after flowering), dilute it according to 1: 1000, and water it every 10- 15 days, and you can give more flowers.

The limit temperature of blue snowflake: 38-40 degrees, which can be planted in Hainan.

Blue snowflakes are not only heat-resistant, but also like high temperature and sunbathing. Hainan Huayou "Youlan 889" introduced before that blue snowflakes are planted directly in the yard. From last year to now, it has been blooming, and the longer it grows, the crazier it becomes.

Summer maintenance skills:

You don't have to worry about the heat and sunshine to raise Lan Xue. Although its branches are thin, they are very explosive. The hotter the weather and the more sunshine, the more it grows and blooms. You must leave enough space for planting, or you will "cover up" other flowers.

To raise blue snowflakes, water them in time after summer. When it is hot, water it almost every day. Leaves will turn yellow if they are short of water for a long time, and bad branches should be pruned in time, otherwise the back will grow too thick and it will be difficult to start.

The limit temperature of Chinese rose: 37-39 degrees, insist on flowering.

There are too many varieties of Chinese rose, some of which are not heat-tolerant, and may be dormant (no flowering, slow growth) when it exceeds 32 degrees, but some varieties are very heat-resistant and sun-resistant, and still bloom in high temperature weather.

Heat-resistant rose varieties:

Zhou Zhen, Kate, Red Dragon, Newman, Angela, Monet, Magic Color, Canary, Aunt Maggie, For My Family, Ballet for Two, Luo Yi, Zixiangrong, Juice Balcony, Plum Pudding, Pang Ba Du, Kelly, Koster, Abraham.

Summer maintenance skills:

To raise Chinese roses, it is best to know the varieties first. The flowering period and compound flower characteristics of each variety are different. Cut off the residual flowers after each flowering, and continue topdressing to ensure the compound flowers. The frequency and quality of compound flowers are mainly determined by variety characteristics, fertility and nutrition.

Water the roses in time after summer, otherwise the yellow leaves and dead leaves will fall off easily, and pay attention to ventilation to prevent pests and diseases. Powdery mildew can be sprayed with carbendazim, chlorothalonil or butyl ether, and it is best to use insecticide (Shi Qihong) for red spider.

Windmill jasmine limit temperature: 37-39 degrees, floral.

Windmill jasmine is not only heat-resistant but also cold-resistant. It can be planted south of the Yellow River. Vines are terrible walls that bloom in summer. They are very fragrant and suitable for raising on balconies, windowsills and near courtyard walls.

Summer maintenance skills:

The windmill jasmine climbs very fast. If you want to climb evenly, you should make a flower stand in advance, such as iron wire or bamboo poles and wooden sticks, and spread out the branches, so that the light will be even and there will be more flowers in the future.

Jasmine windmill belongs to Apocynaceae and is also poisonous, but people will be fine as long as they don't eat by mistake. Keeping it in the yard not only doesn't like bugs, but also has certain insect-proof effect.

Dill limit temperature: 35-37 degrees.

Dill is sown every spring and blooms in summer. In just a few months, a whole wall can be covered, and even the rooftop where the sun is shining can support a shade.

Summer maintenance skills:

Dill basically has no special maintenance skills. It is resistant to shade and sun, and there is no need to worry about sowing in the open space of the yard. If it is a potted plant, you need to water it on time, get more sunshine and give it enough climbing space.

Dill is an annual. Flowers bloom in spring and wither in autumn and winter. Remember to accept the seeds and sow them next year. According to this growth habit, both the north and the south can raise it without any restrictions.

Limiting temperature of jasmine: 37-39 degrees.

The flowering temperature of jasmine is 25-35 degrees, which is conservative. The hotter it is, the more it blooms. On a hot day, it can be opened several times in a row.

Summer maintenance skills:

After the temperature rises, if the jasmine still doesn't move, you can water it with Huaduo 1. When the leaves and branches grow vigorously, it is better to change it to Huaduo No.2 (fertilization interval is about 10 day) or spray potassium dihydrogen phosphate on the leaves to promote flowers.

Molly likes high temperature, but she should also pay attention to watering on time. When water is scarce, it will dry up. The jasmine flower period is very short, about 3 days at a time. After the flowers wither, the branches will be cut short and will soon reopen, which can be opened 2-5 times a year in summer.

Extreme temperature of dragon boat flower: 38-40 degrees.

Dragon boat flower, also known as Yingdan, can be subdivided into several varieties, including relatively low dragon boat flower of Rubiaceae and relatively high shrub dragon boat flower (woody branches), both of which are very heat-resistant.

Summer maintenance skills:

Dragon boat flower is very fond of heat and light, suitable for outdoor maintenance, especially in summer when placed in outdoor sunshine, it grows more and more beautiful.

Dragon boat flowers like acidic and well-drained soil, such as humus and sand. If it is planted in the ground, it should also be planted in a well-drained place.

Limit temperature of small hibiscus: 35-38 degrees.

It's 37 or 8 degrees in summer. When I throw the hibiscus outside, it's all right. Flowers bloom all summer. It is really a recognized flowering machine.

Summer maintenance skills:

After the temperature rose, some flower friends said that it began to have yellow leaves, probably because of insufficient water, or insufficient water, or the air was too dry and dry. In addition to mopping the floor, put a pot of water beside it, and you can also put many pots of plants together.

The little hibiscus flower is not afraid of heat, but it is afraid of boredom. Exposure in hot weather is also good. If you are indoors, open more windows for ventilation and trim them frequently. After each flower blooms, it should be cut short or shaved into a ball, and it will grow up in half a month.

Limit temperature of gardenia: 35-37 degrees.

Gardenia is not afraid of high temperature, especially in Jiangsu, Hubei and other places where gardenia is planted on the ground. In summer, the temperature exceeds 37 degrees, and gardenia planted on the ground is still flourishing, so potted plants may need proper shade.

Summer maintenance skills:

Gardenia is fond of light, but I just bought it and can't be exposed to the sun for the time being. We have to put astigmatism to adapt for about 3 days, and then gradually increase the light. Remember to water on time during maintenance. Once water is scarce, the leaves of gardenia will soon dry up.

In midsummer, gardenias may have finished blooming, so they should be kept in the sun, because July and August are the flower bud differentiation period of gardenias, and if they lack light, the flower buds will not grow well, so they should be kept in the sun and watered in the hottest time.

Extreme temperature of garland lily: 35-37 degrees.

Garland lily is very heat-resistant, and it is also cultivated in summer in Guangdong. Flowering in hot summer season can last from September to 10. Even flowers are like flames.

Summer maintenance skills:

The rhizome of the garland lily is like a yam stick. After it is planted and germinated, it needs more sunshine. Its branches and leaves are thinner than ordinary lilies. It can be raised as a climbing plant and can be guided by a bracket.

The flowering period of garland lily is longer. If it is warmer in winter in the south, the ground planting does not need to be managed, and it does not need to be dug out in winter (the north suggests digging out to dry and store), and the roots below can continue to grow and reproduce.

Extreme temperature in Xia Ju: 35 degrees.

Xia Ju, as its name implies, is the chrysanthemum in summer. The flowers in Xia Ju are a little smaller than those in autumn, but there are many flowers, which are heat-resistant and sun-resistant. The most poisonous west windowsill in summer can also be raised, and it is in full bloom ~

Summer maintenance skills:

Whether you are raising Xia Ju or other chrysanthemums, you should keep ventilation, preferably in the open air or on the balcony or windowsill. The best ventilation effect is to open the window. Chrysanthemum can be topped 2-3 months before flowering to promote the growth of branches, and the flowers will become bigger later.

The flowering period in Xia Ju is from July to September, which is also the hottest period. If there are many flowers in one crop, the residual flowers should be trimmed in time. Topdressing 1-2 times after pruning can blossom again. As for flower shops, chrysanthemums can attract small flying insects, and you can put a stick insect in the pot, which has a good effect.

Limit temperature of hibiscus: 38 degrees.

Hibiscus, also known as Zhu Jin, belongs to the "marathon runner" among flowering plants. Bloom grows all year round, and it can grow at 38 degrees in summer.

Summer maintenance skills:

Fusang is a shrub and can be potted. It likes warm and humid environment. As long as it is higher than 5 degrees, it can bloom in no hurry. Spring and summer are the peak seasons for growth. If properly maintained, more flowers will bloom in summer.

The leaves of hibiscus are shiny, which is the expression of drought tolerance of plants. But when raising hibiscus flowers in summer, we should also pay attention to watering them in time, otherwise they will still dry up. The more leafy the hibiscus, the more you can't forget to water it.

Dianthus extreme temperature: 35-37 degrees.

There are many varieties of carnation. If it is a local variety, it is still very heat-resistant. Wild carnation grows in the cracks under the scorching sun, which is not only heat-resistant but also barren.

Summer maintenance skills:

There are many varieties of carnation, some newly cultivated varieties and exotic varieties are not as heat-resistant and barren-resistant as local carnation, so we should pay attention to distinguish them. If it is a more expensive variety, it is necessary to shade at high temperature.

Carnation is drought-resistant and barren, and likes open air environment. The picture below shows the planting effect of Huayou in Xi 'an. The yellow soil looks more saline-alkali, but the carnation planted in spring is still in full bloom in summer.

Limit temperature of peony: 37-39 degrees.

Although students in the south can't grow peony, they can grow wild peony, which is a kind of shrub with fierce growth and rose-purple flowers. It is very heat-resistant and sun-resistant.

Summer maintenance skills:

Peony grows quickly. If there is enough space, it will soon spread to a large area. But it likes acidic soil, likes heat but is not cold-resistant, so it can only be planted in the south, and potted plants are safer in the north.

Wild peony likes light and is slightly drought-tolerant. If it is potted indoors, you need to put astigmatism for about 3 days when you first get home, and then slowly increase the light. When there is plenty of sunshine, you should keep up with the watering, or you will hang your head easily.

Limiting temperature of fragrant vines: 35-37 degrees.

Xiangtengyuan is a tropical American plant, which was later introduced to China. Originally raised in the south, it likes heat and grows and blooms in the four seasons under warm winter conditions.

Summer maintenance skills:

Xiangman likes an environment with sufficient light. In summer, keep the light and pay attention to watering, because its leaves are thin and its water storage capacity is weak. When the soil is dry, it should be watered thoroughly in time.

Xiangteng is easy to climb. Authentic Xiangteng can climb walls 2-3 meters high. At present, there are many cases in which red cicadas pretend to be fragrant vines. Actually, they are different. The leaves of fragrant vines are relatively large, while those of red cicadas are small and shiny.

Limit temperature of Echinacea purpurea: 38-40 degrees.

There are many kinds of compositae plants, among which Echinacea purpurea is one of the more distinctive ones. Its stamens protrude like pinecones, and its petals are very interesting.

Summer maintenance skills:

Echinacea usually sows in spring, blooms in summer, and it is okay to be exposed to high temperature. It is often used for garden planting. The plants withered in the high temperature, but they still stood upright.

Echinacea is very drought-tolerant, and basically does not need watering. Unless it doesn't rain for a long time, the cones are still on the echinacea after the petals fall. Autumn flower arrangement can be cut, and there may be seeds in it, and it will be broadcast next spring.

Amaranth extreme temperature: 38-40 degrees.

Evergreen is very heat-resistant and sun-resistant, the sun is fierce, and the colors of flowers are more vivid. Although its flowers are different from conventional flowers, they have a unique aesthetic feeling, which people who like naturally like.

Summer maintenance skills:

Qianrihong is resistant to heat, drought and barren. Both north and south can be raised, and it grows rapidly after summer, and can be pruned to promote branches.

Because its flowering period is very long, and it keeps bright colors all the time, it is difficult to judge whether the flowering period is over. Flower friends can touch it. When the flowers are dry, they can be cut and dried, and put in an empty bottle to watch. If there are seeds, you can continue sowing next year.

Limit temperature of five-color plum: 38-40 degrees.

Five-colored plum, also known as lantana camara, is in its heyday in summer and can be seen everywhere in hot areas in the south, but it is actually an exotic species, and is classified as an invasive species because of its excessive growth and adverse effects on other plants.

Summer maintenance skills:

Five-colored plum can be exposed to the sun in summer, but it won't die if it is hot. If it is a potted plant, it is enough to water it in time. If planted in the ground, it should be trimmed and controlled, otherwise it will occupy the growth space of other plants.

In view of the invasive growth of five-color plum, it is best to plant it in pots, which will not have much impact on the environment. However, the taste of five-color plum is not very good, so it is not recommended to put it indoors. It is still very suitable to put it at the gate or in the yard.

Extreme temperature of sunflower: 38-40 degrees.

Sunflower is no stranger to everyone. The hotter it is in summer, the more it blooms. If you think the yard is too sunny for planting flowers, just sprinkle a handful of seeds or insert a branch, and it will soon grow into a carpet full of flowers.

Summer maintenance skills:

Sunflowers are easy to grow. At this time, cutting with 3-5 cm long branches is the fastest. Put them in the soil and water them. After 2-3 days, they will be refreshed and gradually increase the light. If the branches are long, you can cut them and continue to cut a pot.

Sunflowers like basking in the sun. When the sun is sunny, they will open more until the temperature turns cold in autumn. Sunflowers with obvious stamens may bear seeds and will be sown next year. Sunflowers with inconspicuous stamens need to keep warm in winter above 0 degrees.

Limiting temperature of bowl lotus: 37 degrees.

Bowl lotus is very heat-resistant, and it can also be raised in the four-stove area. In the hot summer, a few pots of water lilies are raised on the balcony, smelling the fragrance of lotus leaves and lotus flowers, as if you were at the edge of the lotus pond. ...

Summer maintenance skills:

Bowl lotus is usually planted in March-April, and it takes a long time for lotus seeds to germinate, so it is easy to get the wrong version. Beginners and short-time flower lovers should start with lotus seeds, prepare a pot with a diameter of 12-20 cm (depending on the size of lotus seeds), cover it with a layer of soil, and then add water.

The water in the bowl lotus will be clear after a few days. If it is turbid, try to change the water and scoop out the dirty water on the surface. Leaves should float above the water, and some duckweeds and aquatic plants can be put to purify them. When the sun is fierce in summer, move to a place with astigmatism to avoid the small basin from being sunburned.

If the water tank is big enough, it is also very resistant to the sun. In fact, the bowl lotus likes to bask in the sun, and it can bloom all the time at the temperature of 25-35. Friends in the south can enjoy flowers until autumn, wither in winter, keep it above 0 degrees, and the basin is slightly moist. Turn over the pot and collect the lotus roots, and continue planting next spring.
