How to grow flowers and die easily in summer? All kinds of ventilation measures that must be known for growing flowers in summer

In hot summer, the temperature is very high both indoors and outdoors. Many people say that the flowers and plants raised in their homes are easy to die. In fact, this is mainly due to poor ventilation. Today, let's take a look at various summer ventilation measures for growing flowers.

Succulent plant

After raising succulent plants for a long time, you should know that lack of light will cause succulent products to look bad, but without ventilation, succulent products may die.

The consequences of poor ventilation:

If succulent plants are kept in an unventilated environment for a long time, the soil is prone to moisture, bacteria, black rot and leaf loss.

Ventilation measures:

In summer, you can add a small solar fan to the succulent plant and turn it on and off regularly, which can speed up the evaporation of soil moisture in the succulent basin and prevent diseases and insect pests at the same time.

Rose

Many flower friends do not dare to plant rose in the closed balcony because the balcony is not well ventilated and the rose is very easy to get sick.

The consequences of poor ventilation:

The leaves of the old leaves at the bottom are yellow, high temperature in summer coupled with poor ventilation, damp and closed environment is easy to breed red spiders and outbreaks of powdery mildew.

Ventilation measures:

The growth of summer rose is very exuberant, and the branches are dense, which affects the ventilation within the plant. Flower friends can prune after blooming, cutting off all the overgrown branches and weak twigs of the rose to increase air permeability.

Cuckoo

Cuckoos are most afraid of muggy heat in summer. Strengthening ventilation is the most crucial step for cuckoos to get through the summer safely.

The consequences of poor ventilation:

In hot summer, under the condition of high temperature, if the ventilation is not smooth, the cuckoo will dry up and keep losing its leaves.

Ventilation measures:

Qualified flower friends had better put the cuckoo outside for maintenance. If you can't, you can add a fan next to the cuckoo to enhance ventilation.

Crab claw orchid

Summer crab claw orchid has entered a dormant period, in addition to maintaining in a shady place, ensuring good ventilation is also the key to the success of crab claw orchid in summer.

The consequences of poor ventilation:

In a poorly ventilated environment, crab claw orchids are prone to the outbreak of red spiders, causing the leaves to become yellow and thin, and eventually wither and die.

Ventilation measures:

Summer crab claw orchid needs a cool and ventilated environment, you can put crab claw orchid on the north balcony, open the window, ventilated astigmatism north balcony can help crab claw orchid successfully spend the summer.

Gentleman orchid

Magnolia enters a semi-dormant period in summer, with slow growth, decreased disease resistance and frequent occurrence of diseases and insect pests, so it is urgent to take good ventilation measures.

The consequences of poor ventilation:

In the hot and muggy summer, the magnolia is in a poorly ventilated environment, the basin soil is easy to accelerate the reproduction of bacteria, the soil is seriously anoxic, and the roots will rot in 3-5 days.

Ventilation measures:

Put the orchid on the side of the tuyere, or blow it into the flowerpot with a fan. Do not let the wind blow directly to the gentleman orchid, otherwise the leaves will lose too much water, the leaves will be dim and soft.

These are all kinds of summer ventilation measures. As a flower lover, you certainly can't watch your flowers die, so ventilation measures must be done well.

How to grow flowers in summer? What should we pay attention to when growing flowers in summer?

It is generally believed that flower pruning is best at the end of autumn. In fact, it is necessary to prune flowers and plants safely in summer. After many flowers enter the summer, they are often easy to grow in vain, affecting their flowering and fruiting. In order to keep the plant shape beautiful and fruity, it needs to be trimmed and reshaped. Summer pruning is generally based on measures such as coring, wiping buds, removing leaves, thinning buds, thinning fruits and so on.

(1) pick some grass flowers, such as Begonia, Golden Bell, a string of red, chrysanthemum, Dutch chrysanthemum, early chrysanthemum, etc., and pinch off their tops when they reach a certain height to promote them to be more branched and bloom. Some woody flowers, such as kumquat, should also be heart-picked when the branches grow to about 15-20 cm in order to bear more fruit.

(2) in summer, many flowers often sprout adventitious buds from the base of the stem or branches, which should be erased in time so as not to consume nutrients and disturb the plant shape.

(3) to remove leaves, some foliage flowers should properly cut off old leaves and promote new leaves, then the leaf color will be more beautiful.

(4) Bud thinning, fruit thinning for flowers that are mainly ornamental, such as dahlias, chrysanthemums, roses, etc., excessive buds should be removed in time; for ornamental flowers, such as kumquat, pomegranate, bergamot, etc., when the young fruit grows to the size of soybean grains, the excess young fruit should be removed; for some flowers that cannot bear seeds or are not ready to collect seeds, cut off the residual flowers in time.

(5) plastic surgery for poinsettia, plum blossom, green peach, tiger thorn plum and other flowers, often bend each side branch in summer to make the plant shape plump and graceful.

The comprehensive management of disease prevention and pest control in summer has high temperature and high humidity, which is conducive to the occurrence of a large number of diseases and insect pests. We should carry out the policy of "prevention first, comprehensive prevention and control" and do a good job in prevention and control in the spirit of "early treatment, small treatment and cure" to ensure the healthy growth of flowers.

The main results are as follows: (1) the common diseases in summer are powdery mildew, anthracnose, gray mold, leaf spot, nematode, bacterial soft rot and so on. Powdery mildew is mainly harmful to rose, plum blossom, peony, chrysanthemum, dahlia, begonia, melon leaf chrysanthemum, inverted golden bell and so on. After the damage, the plants were short, the tender shoots were curved, and the leaves were uneven or curled. Buds, leaves, shoots and buds, as if covered with a layer of white powder and grow many small black spots, serious leaves withered and withered, or even the whole plant died. Anthrax is mainly harmful to orchids, Magnolia, Milan, plum blossoms, rubber trees, cactus and so on.

After most flowers are infected by bacteria, there are nearly round disease spots on the leaf surface, the edges are mostly purplish brown or dark brown, the center is light brown or grayish white, and the disease spots are often arranged with small black spots in the shape of wheels. The leaves withered and died when the disease was serious. Botrytis cinerea is mainly harmful to peony, peony, cyclamen, begonia, inverted Admiralty and so on. The damaged parts such as leaves, stems and flowers are brown or purplish brown rotten, gray mildew grows on the disease spot when the weather is wet, and the whole plant dies in severe cases.

The following methods can be used to control the above three diseases:

① thoroughly removed the dead branches and leaves in early spring, cut off the diseased schools, leaves, buds and destroyed them in time, so as to reduce the source of bacteria.

② should strengthen cultivation management, fertilize and water reasonably, pay attention to ventilation and light, make the plant grow healthily and improve the ability of disease resistance.

50% carbendazim or 50% topiramate was sprayed at the initial stage of ②.

(2) there are two kinds of common pests in summer: piercing and sucking mouthparts and chewing mouthparts. The former are mainly aphids, red spiders, whitefly, shell insects and so on. These pests often gather in leaves, tender stems, buds, branches and other parts, with needle-like mouthparts into the flowers to suck juice, causing leaves to turn yellow and curl, resulting in leaf yellowing and shedding. The prevention and control method can be sprayed with 1000-1500 times of dichlorvos emulsion. This medicine is easy to cause drug damage to plum blossom, cherry blossom, rhododendron, elm leaf plum and other flowers and trees, so these flowers and trees should be banned. The latter mainly includes moths, butterfly larvae, various beetles and underground pests. These pests nibble away at the leaves, bite the roots and wither the plants. The method of control is to spray 1000-1500 times of dichlorvos emulsion or irrigate the rhizosphere. High temperature in summer, volatile pesticides, coupled with high temperature when the human body's emission function is enhanced, the absorption of the skin increases, so the poison is easy to enter the human body and poisoning, so summer application, it is appropriate to move the flowerpot to the outside, in the morning and evening.

What you should know about growing flowers in the office in summer

"my succulent plants are wilting and my leaves are dry. What should I do?" Recently, in some flower forums, such help posts have been sent out constantly. Hot summer has come, how to let flowers and plants spend summer safely in a hot and muggy environment? Recently, the reporter went into the offices of several florists in urban office buildings to look for summer flower-growing skills.

Succulent plants are lovable. Summer is a sad "hurdle".

"at two o'clock, the office has become another home. After busy work, isn't it a pleasure to water the flowers, appreciate them carefully and reduce pressure for the work? " This is a passage left by Lancome, a white-collar worker, on the forum. In her office, succulent plants such as Guanyinlian, Black Master, Ji Yulu, Rainbow Jade and Green Bell are all over the windowsill. If you count them carefully, there are nearly 20 varieties.

A white-collar worker surnamed Lu, who works in an office building on Lantian Road in Haishu District, is also a full "succulent control". Her office faces south, and there are two whole windowsills of succulent plants, including silent night, fire sacrifice, obscure moon, silver star, striped twelve rolls, air pineapple and so on. These succulent plants are carefully cultivated in pottery pots, matched with high and low.

"many succulent plants will get out of shape when they grow up and need constant pruning in order to maintain a good figure." Miss Lu said with a smile. In the corner of the office, more than 10 small flowerpots placed on the floor are her "breeding base" for succulent plants. "the pruned branches and leaves are put here to breed. Succulent plants have an amazing ability to reproduce, and a leaf or a branch can give birth to new life. " Miss Lu said.

"now is not a good time for you to come. You are not in good condition now. If you had come two months earlier, you would have looked much better!" Miss Lu refers to "bad condition", which means that some succulent plants have entered or are about to enter a dormant period.

So, how to distinguish the dormant period? People say that depending on the state of growth, the plant stops growing during the dormant period, the leaves are dim and lose luster, and the whole plant looks lethargic, such as the Black Master, after entering the dormant period, the originally full leaves will soften and the luster will disappear.

"Summer is a hurdle for succulent plants, and it may be wiped out!" In order not to let the dormant meat rot, "I'd rather dry than water them. I haven't watered them for more than a week!" Miss Lu said.

Green plants are relaxing and enjoyable. Avoid too much light and not enough humidity in summer.

Compared with succulent plants, green plants are easier to spend the summer. The office of white-collar "snowy love" is recognized as the "most beautiful office" in the building. There are more than 30 pots of green plants such as green apple, ivy, hanging orchid, Guerlain, begonia, tiger tail orchid, anthurium, purple jade, crab claw orchid and Douban green on the windowsill and bookshelves. She sometimes makes a few pots of exquisite flower arrangements to add ingenuity to her desk. "being surrounded by flowers at work can relax your body and mind and improve work efficiency," she said. "

Choose the green plant, the Love of the Snow area attaches importance to the purifying effect of the green plant on the air. The most on her desk is hanging orchid, with six or seven pots. "there are several pots of hanging orchids that my colleagues didn't raise well and got them here for foster care. Although the orchid is easy to raise, the leaf tip is prone to dry scorch and yellowing. Raise hanging orchid in summer, the most taboo light is too strong, air humidity is not enough, improper fertilization, these may cause leaf dry coke yellowing. " Love in the Snow area says that if the leaf tip of the orchid turns yellow and dry, don't worry, move the orchid to a semi-cool place of ventilation, and often spray water to the leaf surface and the surrounding environment to increase air humidity, and avoid leaves when fertilizing. In addition, it is also necessary to observe whether the rotten root is rotten, and the rotten root part should be cut off in time.

Behind her are several half-man-tall green pineapple, whose leaves are as big as the palms of adults, but the hydroponic green pineapple leaves on the table are very small. The same green pineapple, why the difference in leaf size is so big? According to Love in the Snow area, potted green pineapple has been fertilized this year, so it grows rapidly, hydroponic green apple has limited nutrition in water, and its leaves can only be so large. "plants are very smart. Under limited living conditions, they will take the initiative to change their shape according to the environment to adapt to the environment. To this end, hydroponic green pineapple can regularly drop a few drops of special nutrient solution in the water to replenish it. "

Summer watering of flowers and plants is the most exquisite.

How do flowers and plants spend the summer? sun Lijun, deputy director of the Haishu District Greening Office, told reporters that spring, summer, autumn and winter give people the most comfortable feeling of spring and autumn, hot summer and cold winter, and succulent plants have similar feelings to the four seasons.

There are many varieties of succulent plants, including summer type species with winter dormancy and summer growth; winter type species with summer dormancy and winter growth; and spring and autumn type species with summer dormancy and spring and autumn growth. To this end, if you are not familiar with the characteristics of succulent plants, the most conservative approach is: less exposure, less watering, more ventilation.

Watering succulent plants in summer depends on the situation. Most of the active plants in summer are cactus, Euphorbia officinalis and Acanthaceae. For succulent plants in dormant period, the water must be cut off in summer. Once they are watered too much, the roots will rot. But for growing succulent plants, such as Huang Li and Peach Beauty, they need to be watered every 2-3 days.

For green plants, most plants should pay attention to shade and prevent exposure in summer. For indoor flowers and plants, the soil can be watered when the soil is white, and it should be watered thoroughly when watering. Flowers with large leaves, such as emerald and dripping Guanyin, cannot lose water in summer. Once they lose water, they will hurt their leaves, while asparagus should be "dry rather than wet."

At the same time, she specifically pointed out that tap water should not be used directly for watering flowers, because the presence of alum in tap water will lead to soil consolidation and affect the permeability and air permeability of the soil.

In addition, she listed several summer conservation methods for green plants. Summer is the peak growing season for orchids, to ensure the water and nutrients needed for its growth, and to maintain a ventilated and transparent environment; rhododendrons grow slowly in summer, are in a semi-dormant state, avoid scorching sun exposure and excessive fertilization, and should be shaded, watering once or twice a day, and spraying water to the leaf surface and the ground to keep moisturizing and cooling; jasmine blossoms in summer, for this reason, sufficient water and fertilizer is conducive to flowering, spraying leaves with clean water to stimulate its flowering. Milan likes light and heat, grows vigorously in summer, fertilizes before and after flowering, and often sprays water to the leaves; peony is afraid of heat and dampness, the plant should be placed in a ventilated and cool place in summer, do not need too much watering, keep the basin soil moist, so as to avoid rotting roots.
