Flower autumn maintenance skills: hanging orchid geranium autumn maintenance method!

According to the editor of Huinong Network, at present, flower planting is the only way for urban people to purify the air, so the maintenance of flowers and plants in autumn is very important. Here are the autumn maintenance methods of orchids and geraniums arranged by Xiaobian. Flower growers take a look!

Hanging orchid

It is a green master in addition to formaldehyde, and it is a kind of plant that is easy to raise.

Cymbidium likes to be warm and humid. During the period of 20 to 24 degrees in spring and autumn, it grows fastest and requires more water.

At present, the daytime temperature in South China is more than 30 degrees, and the growth is slow, so the water should be properly controlled and ventilation should be paid attention to; in some parts of the north, if the temperature is below 5 degrees at night, outdoor maintenance should be avoided and the room temperature should be kept above 12 degrees; the growth of hanging orchids in the central region is booming, so it is better to keep it moist at any time.

If the ambient air is dry, it is best to spray water to increase the environmental humidity, while scrubbing the leaves every week, which will definitely add to the lush flower of the orchid.

The temperature stable at about 20 degrees is also the best time for Cymbidium to reproduce and cutting. cut off the stolon and insert it into the water, the air root will soon grow and can be transplanted in three weeks.

Orchid

The national orchid is simple in shape and color, but it has the "fragrance of king". It is not easy to maintain and is the representative of "low-key luxury".

The maintenance of orchids focuses on water conservation and drainage to ensure good ventilation and proper sunshine. In terms of water conservation and drainage, the first priority is the selection of plant materials. Orchid plants often use rotten leaf soil and immortal soil that hold water and fertilizer, plus perlite with drainage and ventilation, large coconut bran or cinder, mature peanut or pine bark and so on.

When watering, pour all the plant materials thoroughly, and next time wait for the surface to dry at 3 cm before watering. It can be poured one and a half at a time, or soak the basin properly. Try to keep the plant moist. The environment must be ventilated after watering, so that the roots can not only absorb water but also maintain ventilation.

After entering autumn, the temperature decreases and the orchid grows faster, so it depends on the plant draught to keep moist. In areas where the air is relatively dry, it is necessary to spray more water to moisturize, but be sure to avoid the leaf center to prevent decay.

Autumn is also a frequent season for orchid diseases. Frequent ventilation, cool weather plus sunshine and spraying 1500 times carbendazim solution can effectively prevent the occurrence of orchid diseases.

Geranium

Geraniums have various colors such as red, orange, purple, pink and white. They bloom beautifully, like hydrangeas, like butterflies. They are really full of flowers.

Geraniums like fertilizer, add sufficient bottom fertilizer when changing pots and soil, and irrigate properly with thin fertilizer water for daily maintenance. First, make the roots strong and the plants firm. After the winter, the proportion of phosphate fertilizer will be increased to promote more and more beautiful flowers.

Geraniums in full bloom and growth period, to frequently water each time thoroughly, slow-growing geranium, to control watering, but do not wait for dry re-watering, easy to hurt roots.

Now in autumn, most areas have cooled down, small days grow faster, need to replenish water in time, and pay attention to maintain the right amount of light and environmental ventilation.

The pruning of geraniums is a major event, which greatly affects the quantity and quality of flowers. After flowering, the residual flowers and leaves should be cut off in time, and the branches should be cut weakly at the same time to promote the next blooming.

The strong cutting in autumn should be chosen at the right time, the early days do not slow down, the branching effect is poor, and the survival rate of cuttings is low. If the new branch is too weak before cooling down too late, vernalization will be affected, and the flowering will definitely not be beautiful. The north-south environment is different, the pruning time is also different.

The temperature is stable to about 20 degrees at night, which is the best time for strong shearing, and it is not too late for indoor maintenance in the north. In most parts of the south, it is better to have a strong shearing after a slight drop in temperature.

The growth habits of three kinds of flowers and plants are completely different, but in the same maintenance environment, we can implement different maintenance methods according to their different growth status and habits.

In autumn, it should be raised in this way. Winter, spring and summer can also be followed by examples.

First of all, you should be familiar with your flower, know its most suitable growth environment, know what it is most afraid of, and know what climate it has the fastest reproduction. Knowing this, combined with the existing care environment at home, we will know what to do.

The above are the autumn maintenance skills of flowers arranged by Xiaobian. There are orchids, orchids and geraniums at home. Take action quickly!

Maintenance skills of flowers in winter

Flowers are mainly divided into two types: cold tolerance and cold fear. Most flowers and trees from tropical and subtropical regions stop growing and go into dormancy when they are less than 10 ℃, otherwise they are easy to freeze branches and leaves or freeze to death. Such as southern fir, plantain, pocket coconut, Milan, magnolia, jasmine, pineapple and other plants and cactus directly planted in the basin, the room temperature should be kept at about 3 ℃-5 ℃; while banyan, palm bamboo, rubber tree, aloe, goose palm, epiphyllum, arrows, etc., the lowest room temperature should be 1 ℃-3 ℃. Rose, rhododendron, sweet-scented osmanthus, iron tree and other plants are cold-resistant plants, which can survive the winter safely even if placed outdoors or on the balcony. And Milan, hanging orchid, rich trees and other cold-fearing plants must be moved indoors. Therefore, different flowers and plants must be treated differently. The winter maintenance techniques of some common flowers are briefly introduced as follows:

1. Hanging orchid

Hanging orchids like warm, moist, semi-overcast environment. It has strong adaptability, drought tolerance, but not cold resistance, strict requirements on the soil, and generally grows better in well-drained, loose and fertile sandy soil. Light requirements are not strict, generally suitable for growth in medium light conditions, but also resistant to weak light. The suitable temperature for growth is 1525 ℃, and the overwintering temperature is 10 ℃. Move it indoors in winter and water it every four days, watering thoroughly, preferably at noon, when the water temperature is the same as the air temperature, so as to avoid freezing on the roots. It is appropriate to keep the basin soil slightly moist in winter, and the foliage should be cleaned frequently when placed indoors. When the room temperature is kept at 15-20 ℃, the orchid can grow normally.

2. Green pineapple

Originally from the tropical rain forests of Central and South America, it prefers a warm, humid and semi-shaded environment, and the suitable temperature is 18 ℃ ~ 21 ℃ in the daytime and 20 ℃ ~ 23 ℃ in the evening. Green pineapple can survive the winter safely as long as the indoor temperature is not lower than 15 ℃ in winter. If the temperature is lower than 10 ℃, it is easy to cause defoliation and affect the growth.

3. Ivy

Ivy is more hardy and does not require much sunshine. It is no problem to spend the winter indoors in a shady place. The hot and muggy climate in summer is very disadvantageous to the growth of ivy.

4. Aloe vera

Aloe likes bright sunlight and higher temperature, but avoid strong light exposure. The lowest temperature in winter should not be lower than 2 ℃, so move indoors in time. Although aloe likes water, it can't be watered every day. It can wait until the soil is very dry.

5. Kale

The ability to withstand heavy snow and a low temperature of minus 11 ℃ adds a hint of green to the cold winter. introduction to the north can be regarded as an excellent open-field grass flower in winter.

6. Jasmine

When the indoor temperature is more than 25 ℃ and more potash fertilizer is applied, the branches and leaves can be reduced and the flowering can be promoted.

7. Begonia

The most suitable growth temperature is 15: 22 ℃, preferring warm, humid and semi-shady environment, avoiding high temperature and water stains, short-day sunshine can advance flowering period, while short-day sunshine in winter just meets its needs.

8. Anthurium andraeanum

The optimum growth temperature of potted Anthurium andraeanum is 20: 30 ℃, and the lowest temperature is 14 ℃. Air humidity is the key to the success of Anthurium andraeanum cultivation, therefore, foliar spraying should be carried out many times throughout the year, so that it can continue to blossom.

9. Rhododendron

Cuckoos usually go dormant in winter, but if the balcony or room temperature reaches a certain degree, for example, between 15 and 25 ℃. Even summer cuckoos end their dormancy and blossom constantly. Cuckoos do not need much water in winter and are generally watered every 4 to 5 days.

10. Phalaenopsis

In full bloom, the indoor temperature should be controlled at 15: 18 ℃ and the relative humidity should be 60% and 70%. Do not put flowers on or too close to the heater, do not let the sun shine directly. The watering temperature had better be close to the room temperature, and the spray blade can often be used to increase the humidity. During the growing period, 2000 to 3000 times of the special fertilizer for orchids can be applied, and there is no need to apply fertilizer during flowering.

11. Lily

Most varieties prefer a cool, moist semi-overcast environment and are more resistant to cold, so they will not die of cold even if the temperature drops to 3: 5 ℃ in winter. The suitable temperature in the growing period is 12-18 ℃, and all 12-25 ℃ can blossom normally.

12. Geranium

Geraniums like the sun, so warm, slightly resistant to drought, afraid of stagnant water. Daily management should prune and pick the heart, and cut off the residual flowers after flowering to promote the growth of new flower buds. Multiple coring can promote it to increase branching and budding. At room temperature, as long as the temperature is more than 15 ℃ and not less than 8 ℃ at night, you can open jubilantly throughout the winter if you see the dry water supply. About 10 ℃ can maintain the evergreen state.

13. Iron orchid

Blue-purple florets bloom from autumn to the following spring. Loose, well-drained rotten leaf soil or peat soil is required to keep the basin soil moist and bright, and the winter temperature is not lower than 10 ℃.

Key points of maintenance of potted flowers in spring

The temperature difference between morning and evening in early spring is very large, sometimes the temperature at night will be below zero, and sometimes there will be late frost or cold snap. At this time, keeping the basin soil dry and doing a good job of anti-freezing is still the key. It is best not to ventilate for a long time, let alone put the plant in the place of air convection. Therefore, potted flowers should come out of the house a little later and not too early in spring, and should be slow rather than urgent. Generally speaking, the method of window ventilation can be taken about 10 days before leaving the room, so that it can gradually adapt to the external temperature; you can leave the room in the morning and enter the room in the afternoon; leave the room in cloudy days, but not in windy days.

Change the pot for sap sprouting potted flowers, such as June snow, pomegranate, rose and other flowers and trees with strong cold protection, planted for several years, the basin has been too small, should be carried out at this time to change the soil. The basin soil should have a certain amount of mountain mud, and other humus soil can be used. For flowers and trees that are blooming or appreciating fruit, they should wait for flowers and fruits to fall, such as kumquat, camellia, rhododendron and so on. For flowers and trees in a semi-dormant state, such as big leaf masts, hanging orchids, etc., pots can be changed before and after the Qingming Festival. For cold-fearing flowers and trees, such as Milan, Zhulan, jasmine, epiphyllum, arrow lotus, as well as most foliage plants such as rubber trees and rich trees, they should continue to keep warm from the cold, and change pots and soil after Qingming Festival.

Pruning according to the growth characteristics of different kinds of flowers, pruning, root pruning, heart-picking and leaf-picking and so on. The rose, mulberry and poinsettia that bloom on the annual branches can be re-cut to remove withered branches, disease and insect branches and overdense branches that affect ventilation and light. For rhododendron, camellia, Yingchun, gardenia, etc., which bloom on biennial branches, it is usually only necessary to cut off diseased and over-dense branches.

Water and fertilizer management to fertilize flowers in early spring, we should grasp the principle of "thin fertilizer less, gradually increase", should apply fully mature thin cake fertilizer and water, the number of times should be from less to more. The time of fertilization in spring should be in the sunny evening.

Early spring watering should also pay attention to the right amount, should see dry and wet, do not water too much at once. In late spring, the temperature is higher, the sun is stronger, the evaporation is larger, watering should be diligent, and the amount of water should also be increased. In short, watering potted flowers in spring should grasp the principle of not drying and watering, watering must be thoroughly watered, and avoid stagnant water in the basin. Watering time should be carried out before noon, and the soil should be loosened in time after each watering.

Breeding in spring is the best time for cutting, planting and sowing potted flowers. Such as rose, geranium, spring, pomegranate, etc., can be cut off robust branches for cutting; orchid, asparagus, orchid, can be propagated; such as mimosa, impatiens, morning glory, string red, peacock, marigold, colorful pepper and other herbaceous flowers, can be sown or on demand for reproduction.

Prevention and control of diseases and insect pests in spring is the season of flowers in full bloom, but it is also the period when diseases and insect pests begin to multiply, so it is necessary to check frequently, detect early, prevent early, and treat early. The common pests in spring are aphids, red spiders, whitefly, shell insects, etc., and the common diseases are powdery mildew, rust, black spot and yellowing. Melon and leaf chrysanthemum, dahlia, impatiens and rose are easy to get powdery mildew; crabapple, rose, peony and bamboo are easy to get rust; peach, rose and plum blossom are vulnerable to aphids; camellia, pomegranate, rhododendron, rose, hibiscus, clove, begonia and evergreen are vulnerable to shell insects, which should be prevented and controlled early.
