Maintenance tips of hanging orchids

Literally, the name "hanging orchid" is, of course, an "orchid" that can hang a potted orchid and hang the entire flowerpot with a rope or net, or an "orchid" with hanging leaves. Yes, but orchids and orchids are two completely different kinds of flowers.

Orchid belongs to Orchidaceae, originated in China, is one of the famous flowers in China, and its leaves grow upward in clusters. Cymbidium belongs to Liliaceae, which is native to South America. In addition to having clumps of leaves similar to orchids, long stems are drawn from the soil, and bundles of leaves grow at the top of the stem, and the base of the leaf cluster takes root, which can be cut off to form a new plant. If the hanging stems and branches extend in all directions from the center of the basin, it will form a unique basin of flowers that can hang in the air.

And these four-way extension of the long stem, there are often white flowers. The color of the leaves varies from variety to pure green and with white or light yellow edges. People give them a good name: Phnom Penh orchid or silver-edged orchid. Hang the orchid in front of the window or indoor any suitable space to watch, it never compete with other flowers for territory, and strong adaptability, do not choose soil. Although the leaves are slender and beautiful, they are drought-resistant because they have thick fleshy roots.

On the contrary, too much watering will cause root rot and hinder growth. But if the indoor air humidity is too dry, such as hanging in a heated room, the humidity is too low, the leaf tip will appear dry phenomenon. At this time, the available household sprayer often sprays water on the leaf surface. Although the hanging orchid is not as eye-catching as the rose, can create a cheerful atmosphere, but it is chic, elegant and clear-hearted, giving people quiet enjoyment. Moreover, it does not require too much care, and has the characteristics of being consistent throughout the four seasons and not occupying valuable indoor sites. Often make people who love flowers after a variety of flowers try, finally choose it, accompany people's life for a long time, decorate the room space all the year round.

Key points of winter management of nursery tips for winter management of potted flowers in nursery

With the advent of winter, people move potted flowers indoors one after another to let them survive the winter safely. In order to make potted flowers have luxuriant branches and leaves and luxuriant fruits in winter, special attention should be paid to the following links in management:

Potted flower nursery should pay attention to light is a necessary condition for flowers to survive. The location of flowers after entering the room should take into account the characteristics of all kinds of flowers. Flowers that usually bloom in winter and spring (such as crab claw orchid, cyclamen, claw chrysanthemum, poinsettia, camellia, etc.) and grass flowers sown in autumn (such as carnation, goldfish grass, etc.), as well as sexually light-loving and warm flowers (such as Milan, jasmine, Magnolia, Fusang, etc.), should be placed on or near the windowsill where there is plenty of sunshine Some flowers that like semi-overcast in summer and light in winter (such as orchids, golden bells, etc.) also need to be put in sufficient sunshine; flowers that like warmth and half-light (such as asparagus, four seasons begonia, rhododendron, etc.) can be placed close to the windowsill; evergreen flowers and trees that like sunshine but can endure low temperature or dormant flowers (such as sweet-scented osmanthus, citrus) can be put in cool places with scattered light (above 0 ℃). Indoor should pay attention to ventilation, which can not only reduce the occurrence of diseases and insect pests, but also conducive to the robust growth of flowers.

Attention should be paid to watering

Improper watering of potted flowers in winter will often result in poor growth or rotten roots. Generally, indoor potted flowers are watered 2 or 3 times a week, and each time should be watered thoroughly.

Prevent the emergence of "half waist water". Water for watering flowers must be used in the sun so that the water temperature is close to room temperature (the difference between soil temperature and air temperature can not exceed 5 ℃). Watering time is mostly around noon, if watering in the evening is cold at night, the roots of flowers are vulnerable to freezing damage. Winter indoor air is dry, in addition to watering can also be appropriate spray water, foliage plants, such as tortoise back bamboo, asparagus, iron tree, rubber tree, etc., should often give foliar spray water, dust cleaning to facilitate photosynthesis.

Fertilization should be flexible

In winter, fertilizer should be stopped for dormant or semi-dormant flowers, such as pomegranate, rose, cactus, variable leaf wood, Guangdong evergreen, etc., but these flowers and trees must be changed once in early winter or early spring, in order to facilitate the growth and flowering and fruiting of the following year. Foliage such as tortoise back bamboo, Tianmen winter, spring feather, one-leaf orchid, etc., can be applied appropriate amount of compound fertilizer and ferrous sulfate, once a month is appropriate.

And a certain amount of potash fertilizer can protect against cold and lodging. This kind of flowers can be added with granular potassium dihydrogen phosphate or calcium superphosphate along the pot wall, and the suitable fertilization time is in the bud growth period. Fruit observation should increase the application of phosphate fertilizer, such as cinnamon, golden bean, bergamot, firethorn and so on. The method is to apply a small amount of solid phosphate fertilizer from the edge of the flowerpot until the fruit is nearly ripe.

Pruning should seize the opportunity

"Seven points depend on management, and three points on scissors." Through pruning to make flowers neat, graceful posture, flowers and fruits. Winter is the most pruning of flowers.

In a good time, for the pile head of elm, sparrow plum, triangular maple, heather and banyan tree for the purpose of ornamental dry branches, the dense branches, disease and insect branches, long branches and weak branches can be cut off, and the other branches can be shrunk properly to keep the pile head clear and fresh. For the flowering species such as wax plum, plum blossom, spring welcome, rose, poinsettia, hibiscus, rose, etc., the annual branches can be cut off from the base 2cm to 3cm after shedding and falling leaves, so as to promote the germination of the reserved basal buds and more new shoots, so as to ensure that the leaves grow luxuriantly in the following year. In addition, the vast majority of potted flowers can be combined with pot shaping and pruning in early spring. For deciduous flowers, the pots must be changed before the new buds germinate, otherwise it will cause water imbalance and lead to poor growth or death of plants.

Winter maintenance of foliage plants

In order for foliage plants native to tropical and subtropical regions to keep their leaves green and full of vitality in winter, the following should be done:

Keep warm and prevent frost

The minimum temperature requirements for overwintering of different foliage plants are different, and the cold resistance of different varieties of the same kind is also obviously different. Therefore, it should be carried out in batches and classified to overwinter according to different regions, plant species and varieties. Keeping warm and anti-freezing is an important maintenance work for foliage plants to survive the winter safely. According to the different requirements of foliage plants for overwintering temperature, the author thinks that they can be divided into four categories and take different measures to keep warm and prevent freezing.

First, foliage plants whose overwintering temperature can not be lower than 5oC, such as asparagus, ivy, goose palm autumn, star anise gold plate, flowers and leaves, taro, cold spray, sunflower, etc., these plants have a certain cold resistance, can survive the winter safely under general cold protection facilities, and can also enter a single-layer plastic greenhouse or general greenhouse.

Second, foliage plants that can not be lower than 8oC, such as swallow palm, Saxifraga, jade emperor, fish tail sunflower, Buddha belly bamboo, red bird nest fern and so on. Have a certain degree of cold resistance, but the coldest should be covered with a layer of plastic film in the greenhouse or indoor.

In winter, it should be placed in a two-story plastic greenhouse or a greenhouse covered with a layer of plastic film.

Fourth, foliage plants that can not be lower than 15oC, such as sunflower, variable leaf wood, white reticulate grass, rich tree, Boston fern and so on. The requirement for overwintering temperature is relatively high, so it is best to put it in a greenhouse with heating equipment. If there is no heating condition, it can be placed in a two-story plastic greenhouse. Southern conservation should cover the top of foliage plants with a layer of plastic film between 3 pm and 9 am the next day, and uncover it after 9: 00 am the next day.

2. Proper watering

After winter, the growth of foliage plants is basically stagnant, some plants enter the dormancy stage, the water absorption capacity is also greatly reduced, watering should not be too much, too much. Sufficient water should be poured at one time before entering the shed or room, and the basin soil should be kept slightly dry during the period in the shed, so as to facilitate the overwintering of foliage plants. When it is found that the basin soil is too dry, it should be watered at 11:00 on a warm and sunny day, and the amount of water should not be too large or watered in the morning or evening. The water temperature should be similar to the room temperature, and the temperature difference should not be too large. Foliage plants are usually watered once a month in winter, and too much is easy to cause root rot. The indoor air is dry in northern winter, such as peacock bamboo taro and other plants need to spray leaves with cold water during the day to improve indoor humidity and maintain their beautiful leaf color; during the overwintering period, sea taro spray warm water every 3-5 days to keep the leaf color dark green; flowers and leaves are evergreen. In winter, warm water needs to be sprayed 2-3 times a week to clean the foliar dust to improve indoor air humidity and make patches bright and strong.

III. Ventilation

Foliage plants in the greenhouse or indoor winter, need a certain amount of air humidity, but not too high. Therefore, it is necessary to open doors and windows in sunny and warm days to adjust the air humidity, especially the high air humidity in the plastic greenhouse, we should pay more attention to ventilation. Ventilation is generally appropriate from 9 am to 3 pm. Winter cultivation of foliage plants light is also very important, oblique sunlight in winter, the light intensity is half of that in summer, for some large sunny woody foliage plants should be placed on the outside of the shed, such as Xianglong blood tree, fish tail sunflower, rubber tree, variable leaf tree and so on. Under sufficient light, foliage plants also become thinner and yellow in winter. For some small herbaceous foliage plants, they should be placed in high places, such as asparagus, colored leaf grass, shade-tolerant and half-shade foliage plants, such as green apple, brown bamboo, loose-tailed sunflower, tortoise back bamboo, asparagus, cold water flower, sea taro, plantain, etc., these plants also need a certain amount of light in winter, due to the high humidity in the shed, diseases and insect pests will occur if there is a frequent lack of light, so it is necessary to "turn the shed" to change the position during overwintering. Ensure the safety of foliage plants through the winter.

1. Pay attention to pruning and shaping the branches and leaves of deciduous plants.

2. Pay attention to topdressing before winter, winter flowering plants such as wax plum, and spring flowering plants.

3. Plants that are not hardy should be wrapped in trunk, and canopy should be covered with thin film.

4. In general, there can be no watering in winter, but if there is a long-term drought, we should pay attention to replenishing water. (winter is also a good time to get rid of insects, pay attention to observe the eggs on the branches of deciduous plants, turn the soil to kill overwintering larvae, etc.) the cultivation method of Gardenia jasminoides the leaves of Gardenia jasminoides are yellow and do not bloom.

In the flowers, gardenia is undoubtedly one of the more familiar flowers, people like to breed at home, but many people do not know much about the breeding methods of gardenia, resulting in a lot of problems in the breeding process, such as yellowing leaves, not blooming and so on. Today, the editor introduces the breeding methods of gardenia and the reasons why gardenia leaves are yellow and do not blossom.

(gardenia is planted in the courtyard and has a strong ornamental effect.)

Gardenia grows like one in the four seasons, the leaf color is evergreen, the fragrance is elegant when blooming, and the white flowers are white, which is particularly beautiful and very attractive. It is often used for potted plants in courtyards and balconies. It has strong environmental adaptability, can grow well in these places, and has strong decorative and ornamental effects. The following editor will talk about the cultivation methods of gardenia from the various characteristics of gardenia.

First, sour soil culture, gardenia need scattered light, so like sour soil, if the soil is alkaline, it will make gardenia can not absorb iron very well, which has a great impact on the formation of chlorophyll, and further cause flower branches to wither and even die; so the soil must use loose, fertile acid soil, you can also add some substances with such effect.

(gardenia has a good decorative effect)

Second, put in a cool place, gardenia must not be exposed to the scorching sun, otherwise the leaves will be withered and yellow, but it does not mean that it should be put in the whole shade, because it has a certain demand for light, it is best to keep 60% of the light every day, in addition, after entering April, fertilizing should be carried out twice a month.

Third, the air humidity, gardenia like to be wet, so the air can not be too dry, according to expert statistics, if the air humidity is less than 70%, it will affect the normal opening of flowers, but if it is too wet, it will cause rotting roots and yellow leaves, so in addition to normal watering, we should often spray clean water nearby. Another problem we should pay great attention to is that water should not be watered too much, otherwise it will also affect growth. So how to water gardenia?

A, when you see the soil is dry, knock on the flowerpot with your hand. If there is an empty sound, it needs watering. The bottom of the flowerpot starts to leak and stops. It is better to add some eggs and soy milk to the watering water, which is more conducive to growth.

(gardenia in full bloom, different beauty)

Fourth, fertilization tips, gardenia like fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer, must not save trouble, otherwise it will cause thick branches, big leaves, thick green, it will lose its own appreciation effect.

Fifth, temperature requirements, the growth temperature of gardenia can not be too low, because it likes temperature, generally speaking, the temperature of the growing period is 18 to 22 degrees, 5 to 10 degrees in winter, and frostbite if it is less than 10 degrees below zero, which should be paid special attention to in the north.

Sixth, proper pruning, gardenia is very easy to grow luxuriant branches, and cause airtight and disorganized feeling, which will cause nutrition dispersion and poor ornamental, so it is necessary to prune it, it is best to choose three main branches when pruning, and cut off the roots and tillers to sprout new branches at any time, and the branches should be truncated in time after the flowers are shedding, so that new branches will sprout under the cut. When the new branch grows three nodes, it is necessary to pick the heart so as not to grow blindly.

(put the gardenia in the sun.)

Seventh, disease prevention, we usually see four kinds of gardenia diseases:

A, iron deficiency, which is the most common, iron deficiency will cause the formation of chlorophyll, and then make the leaves lose green, when you can use ferrous sulfate water and low concentration of black alum water, three times a month.

B, magnesium deficiency will lead to yellow veins of the lower old leaves of Gardenia jasminoides, so it is necessary to spray with low concentration of magnesium sulfate solution.

C, the soil is too wet or too dry, this can be seen in the third point

D, the sun exposure, this can refer to the second point.

Eighth, breeding methods, Gardenia jasminoides generally have two propagation methods: cutting and striping

A, cuttings, 15 cm long with twigs in the rainy season, planted in the seedbed and rooting in 12 days.

B, in April, biennial branches were selected, which were 2O-25 cm long, buried in the soil and kept moist, about 30 natural roots were separated from the mother plant in summer and planted in the next spring.

The reason for the yellowing of the leaves of mast flower

First, improper moisture

A, too much watering, in this case, the tender leaves of the masts are dark yellow and dull, but there is no obvious change in the old leaves, so just take the flowers out of the pot and put them in a cool, ventilated place and put them back after the soil dries.

B, lack of water, leaf tip or edge withered, dry, old leaves withered and yellow shedding from bottom to top, but the growth of new leaves is relatively normal, at this time should be fully watered and thoroughly watered.

(there are many reasons why gardenia leaves turn yellow.)

Second, improper lighting

A, the light is too strong, the sunrise part of the leaf appears macula, at this time only need to move it to the shade to maintain can be restored, the new leaves will no longer have macula.

B. when there is not enough sunlight, the leaves will turn yellow or even fall off, as long as you put them in the sun to replenish the sun.

Third, improper fertilization

A, excessive fertilization, mainly manifested in the brown appearance at the tip of the new leaves, the thickening and dullness of the leaves, and the scorched yellow shedding of the old leaves. At this time, it is necessary to stop fertilization immediately, and in serious cases, the soil should be washed to reduce the concentration. B, insufficient fertilizer will also cause plant yellowing, such as iron deficiency, the leaves are light yellow or white, and the leaf veins are still green, so it is necessary to spray 0.2% Moe 0.5% ferrous sulfate for prevention and control; magnesium deficiency, the old leaves turn yellow first, then the new leaves turn yellow, and the leaf veins are still green. At this time, 0.7%-0.8% boron and magnesium fertilizer can be sprayed to prevent and control.

Fourth, the temperature is too low, too low temperature will also cause leaf yellowing, as long as it is moved into the high temperature.

The reason why the mast flower does not bloom

First, improper water and fertilizer, once excessive, it will cause plant overgrowth, reproductive growth without enough nutrients will affect the formation of flower buds, resulting in no flowering or few flowering, some blooming, or even immediately fall off. In the period of flower bud differentiation, special attention should be paid to the collocation of phosphorus and potassium fertilizer, such as 0.2% potassium dihydrogen phosphate solution, which is conducive to flower bud formation and bud pregnancy; excessive fertilization and watering during the bud period will also cause falling flowers and seedlings.

(gardenia hasn't blossomed all the time, so be careful.)

Second, the light is not suitable, Jiaozi flowers like shade, we should pay special attention to the strong light in summer and too weak light in winter, too strong and too weak will affect the blossom.

Third, the soil contains high alkali, Jianzi flower likes acidic soil, cultivated mast flower soil contains high salt and alkali, it will cause plant yellowing, and eventually affect flowering.

Fourth, no pruning and shaping, messy masts and branches, a large number of miscellaneous branches consuming a lot of nutrients and branches too dense, affecting photosynthesis, are all important reasons for not flowering.

Fifth, diseases and insect pests are serious. I believe everyone can understand that serious diseases and insect pests are bound to lead to the loss of flowers.
