What are the most difficult flowers and plants in summer?

Hello, topic, I hope to communicate with you.

According to my practice of potted flowers, I tried to rank the most difficult summer flowers:

First place: Guayeju. Guayeju is also called Qianrilian. Guayeju is also worthy of the name, with leaves like melon leaves and flowers like chrysanthemums, but Qianrilian seems to be worthy of the name. A thousand days should be about three years, but according to the data, you should do more practice for one or two years. In fact, we all plant potted plants at home for one year. Flowering from February to March, it is one of the main ornamental potted flowers during New Year's Day and Spring Festival. Usually a single potted flower can last for more than 40 days. Chrysanthemum likes warmth, does not tolerate high temperature, and grows best at 15℃-20℃. When the temperature is higher than 2 1℃, overgrowth can occur, which is not conducive to the formation of flower buds. When the temperature is lower than 5℃, plants stop growing and developing, and when the temperature is lower than 0℃, they will be frozen. The suitable temperature for flowering is 10℃- 15℃. When it is lower than 6℃, it can't be in bud. When the temperature is higher than 18℃, the flower stems will become slender and the ornamental value will be affected. Indoor potted plants will wither and die above 30℃. Therefore, most of the potted plants we bought from the flower market are very difficult to spend the summer, so naturally they should be ranked first.

Second place: cyclamen. Cyclamen cyclamen, also known as Pin Guan, rabbit ear flower, etc. , with healthy plant shape, moderate height, lush foliage, bright colors, special flowering period and unique flower shape. The optimum growth temperature of cyclamen persicum is 10 ~ 22℃, and the temperature difference between day and night should be 8 ~ 10℃. When the temperature exceeds 28℃ in summer, cyclamen bulbs begin to hibernate, and the dormancy period is not well managed, and the bulbs are easy to dry up or rot. Although Cyclamen persicum is a perennial bulbous herb flower, few of us can spend the summer safely on the balcony by potted plants. Even if it is dug out and preserved, the bulbs will not escape the fate of decay when the temperature is high. Coupled with the bulbs from cyclamen, the old people don't keep small ones. The seedlings that were sown and propagated in that year grew vigorously and flowered a lot, but the flowers of perennial cyclamen bulbs were scarce year by year. In this way, there is no need to keep it.

Third place: geranium. Geranium prefers warm winter and cool summer, and the optimum temperature is 15-20℃. In winter, the room temperature is kept at 15℃ during the day and not lower than 8℃ at night, so it can bloom normally. When the temperature is about 30 degrees in summer, the yellow leaves will wither and fall off, and the plants will enter a dormant period. During the summer vacation of geranium, the stems of geranium will turn black and rot in case of long-term high temperature weather. In view of this, it ranks third.

Fourth place: calla lily. The suitable growth temperature of calla lily is 15 ~ 25℃, and the night temperature is not lower than 13℃. When the temperature is higher than 25℃, plants will go into dormancy. Too much watering can easily lead to root rot.

Fifth place: Clivia. Why is Clivia ranked fifth among the most difficult summer flowers in Sun Shan? Although there are many topics about Clivia rotting in summer, I think there is still a lot of room for appreciation of Clivia's high temperature resistance. The mature plants cultivated by my seedlings have been maintained on the balcony for three consecutive years, and the highest temperature has reached 40 degrees. Furthermore, even if the temperature is very high and the leaves of Cymbidium rotundifolia are in poor condition, there is still no worry about life. Compared with Guayeju, cyclamen, geranium and calla lily, it is also possible to rank fifth.

Sixth place: upside down Admiralty, seventh narcissus, eighth Zhu Dinghong, ninth freesia, tenth hyacinthus orientalis.

Summary: Ball plants and succulent root plants are the most difficult to bloom in summer.

For the ten kinds of flowers listed above, attention should be paid to heatstroke prevention and cooling during summer maintenance, often spraying water on the ground and air, appropriately increasing air humidity and shading, at the same time reducing watering amount, stopping topdressing, and especially strengthening ventilation to prevent roots or bulbs from rotting.

Hello, Jiahuaji answers for you! Some netizens asked what are the most difficult summer flowers and plants? Every flower friend's blacklist may have several plants that will die in summer. If you want to arrange them in order, each flower friend may have a different understanding. Here are some flowers that are difficult in summer.

fat

Generally speaking, except for succulents planted in summer such as cactus and Euphorbiaceae, most other succulents will go into dormancy in hot summer. At this time, we must pay attention to shading and ventilation, and properly control water to lose weight, otherwise the ventilation will be poor, the environment will be sultry, and there will be too much watering, and there will be more meat and water in minutes.

fuchsia

Hanging upside down admiralty is also called hanging bell begonia. Flowers are beautiful, like small palace lanterns hanging on branches, but they are also notoriously difficult in summer. The summer climate is sultry, and if the ventilation is not good, it will easily lead to the stem and even the root system turning black and rotting, so like meaty, we should pay attention to strengthening ventilation. In addition, due to the weather factors in summer, it is very easy to cause the golden bell to hang upside down after rain, so it is necessary to pay attention not to expose to the sun immediately after rain. Move to the shade.

pelargonium

Geranium is comparable to the upside-down golden bell. Stem rot is very easy to occur in summer, and the stems turn black and rot. Once it happens, we can only cut off the parts that are not rotten quickly to avoid being wiped out by the whole army. Stem rot is also prone to occur under high temperature and humidity conditions, so attention should be paid to the shade, ventilation should be strengthened, and the permeability of basin soil should be better. Try not to use glazed porcelain pots.

hydrangea

Hydrangea likes semi-cloudy and cool environment. In summer, the sun is vicious and the temperature is high. If directly exposed to the sun, it is easy to burn the leaves, resulting in dry leaves and premature aging of flowers. Therefore, hydrangea must pay attention to shading in summer and maintain it under scattered light. (Image courtesy of Huayou)

As long as you know the growth habits of flowers and plants, there is no flower that is difficult to spend the summer.

Growing flowers is a science. It is embodied in botany, plant physiology, landscape meteorology, garden plant breeding, garden plant protection, soil fertilization and other disciplines.

If you want to raise flowers well, you must have enough knowledge about flowers. Master the growing environment of flowers, the soil they need, whether they need sunlight or shade tolerance, whether they like fatness, whether they like drought or humidity, whether they like warmth or cold tolerance, whether they are waterlogged or drought-tolerant, and what seasons are the growth period, dormancy period and flowering period of flowers. If you choose to plant flowers according to your living environment, there will be no problem of spending the summer.

It's difficult to spend the summer. This only shows that you know nothing about growing flowers. Failing to maintain flowers according to the needs of their growth. In the past, people often discussed how southern flowers spend the winter in the north, but how flowers spend the summer is rare. As long as you have a general understanding of flowers, it is not difficult to spend the summer.

For example, some people say: calla lily is difficult to spend the summer, but it is not. People who think calla lily is hard to spend the summer just don't really understand its growth habits.

Calla lily has a long and beautiful flowering period, so it is easy to spend the summer. Calla lily is dormant in summer, growing vigorously in spring and autumn, and indoor maintenance in winter, as long as there is enough sunshine and enough light for a long time. Compared with strong light, calla lily prefers long-term light. When the room temperature is suitable in winter, calla lily keeps growing and blooming.

Calla lily is dormant in summer. Stop watering in late May. When the branches on the soil are dry, dig out the roots of calla lily and put it in a cool and ventilated place to sleep. After dormancy, calla lily was replanted in September and gradually managed normally.

If you don't understand the growth habits of calla lily, continue to fertilize and water in summer, and then shade, it is difficult for calla lily to spend the summer.

So as long as you know the growth habits of planting flowers, it is not difficult.

The hardest summer? This problem may be selective for most plants. Affected by the natural environment, temperature, humidity and nutritional conditions are all influencing factors.
