Growing Techniques Jan 1, 1970 0 views

Orchids are a common potted flower in daily life. Since ancient times, many poets have written poems about orchids, and orchids bloom in all four seasons and are deeply loved by people. In daily life, many novice flower growers want to grow orchids, but they do not know how to grow them. Orchids are actually very easy to grow, as long as you understand the orchid cultivation methods and precautions below

1. How to grow potted orchids: water more and give less sun

Orchids bloom in all four seasons, and different orchid varieties have different flower colors. Since they bloom in all four seasons, you can probably guess that this flower is easy to grow. So how do you grow orchids? The first things to pay attention to are its watering technique and light. As long as you master these two points, your orchids will certainly grow very well. Below we explain the orchid cultivation methods and precautions in detail.

2. Orchid cultivation methods and precautions

1. Care location

In all four seasons, apart from winter when we need to keep orchids indoors for cold protection and warmth, in the other three seasons we can keep orchids outdoors. In summer and autumn, when temperatures are high and sunlight is too intense, we need to provide semi-shade care. Orchids kept indoors are best placed in a ventilated spot, and they need plenty of light; ideally in winter they should be able to receive sunlight.

2. Soil

The soil used for orchids should be mainly humus, chiefly leaf mold or mountain forest humus soil. You can also use leaf mold, vermiculite, perlite, and so on to artificially mix a loose, airy, water-permeable growing medium.

3. Watering method

Watering orchids should be based on the species, growth condition, and local climate, and you should aim for moist but not wet, dry but not parched. Do not water too much or too little, and grasp the principle of not dry in autumn and not wet in winter. In summer, when temperatures are high and orchids are in a period of vigorous growth, water on average 1 to 2 times a day. In winter, when temperatures are low and the plants are dormant, watering should be controlled, generally once every 5 to 7 days, but Cymbidium sinense, which blooms in winter, needs more water.

Precautions: When watering, be careful to prevent water droplets from splashing onto the leaves, so as to avoid black spots that affect the ornamental effect. During the orchid's growth period, water should often be sprayed on the leaves, and in summer water should also be sprinkled on the ground around the flower pot to increase air humidity and promote the orchid's growth and development. For watering orchids, rainwater and snow water are best; if tap water is used, it should be stored for 2 to 3 days before use.

4. Light

Orchids prefer shade and fear direct sunlight. However, they cannot be kept in a dim place for a long time, as this will cause poor growth and even few or no flowers; appropriate light is very necessary. If we grow orchids indoors, we can place them on a flower stand by the windowsill or on a table, and we need to rotate the pot every so often to prevent the plant from growing leaning to one side due to phototropism.

5. Fertilizing

Fertilizing is also very necessary in orchid cultivation. We generally use the principle of light fertilizer applied frequently, and it is best to control the amount of each fertilization to a small quantity. We can use bean cake water and apply it once every half month, and applying monopotassium phosphate once every month gives even better results. Generally in summer we do not need to fertilize, because summer temperatures are high and water evaporates easily, which can make the fertilizer solution too concentrated and burn the roots.

3. Precautions for growing orchids

1. During orchid cultivation, withered yellow old leaves and diseased or pest-damaged leaves should be continually cut off to help ventilation. After flower buds emerge from the soil, each plant should keep one strong flower bud and the rest should be cut off, so as to avoid consuming too many nutrients and affecting next year's flowering. After the flowers fade, the flower stems should be cut off.

2. In [season] pay attention to cold protection. Terrestrial orchids have strong cold resistance, while tropical orchid types require a higher overwintering temperature, so they should be moved indoors early or protected from cold with a plastic shed to avoid freezing; the room temperature is best kept at 10 to 15°C, and indoor care should pay attention to ventilation. As the climate gradually warms in spring, gradually move the orchids to the courtyard or balcony.

3. For home cultivation of orchids, natural rainwater, stream water, well water, and river water are best. If tap water is used, it should first be stored in a vat and exposed to the sun to remove bleaching powder before use. If tap water is used to water flowers for a long time, the growing medium will gradually become alkaline. Ferrous sulfate can be applied once every so often to increase soil acidity. In addition, watering orchids with fermented rice-washing water can also keep the soil in a slightly acidic state.

How to grow orchids? Orchid cultivation methods and precautions

Introduction: Orchids are also called orchid grass and Chinese orchids. They are one of China's traditional precious flowers and also a world-famous flower. Together with plum, orchid, bamboo, and chrysanthemum, they are collectively called the “Four Gentlemen.” They look plain and unadorned, but in fact have a delicate fragrance that carries far, and they are highly ornamental. Many leisurely refined people like to grow orchids. So, do you know how to grow orchids, and what are the orchid cultivation methods and precautions? Below, the editor of First Agricultural Economics introduces them to you.

1. Soil selection

The soil used for orchids should be mainly humus, chiefly leaf mold or mountain forest humus soil. In the south, the humus soil from the place of origin is used, commonly known as orchid mud; you can also use leaf mold, vermiculite, perlite, and so on to artificially mix a loose, airy, water-permeable growing medium. Generally, a growing medium is made by mixing 8 parts leaf mold and 2 parts river sand, or 7 parts leaf mold, 2 parts perlite, and 1 part river sand, or 6 parts leaf mold (peat soil), 3 parts compost soil, and 1 part river sand mixed evenly. All the growing media prepared above are slightly acidic.

2. Fertilizing method

Orchid fertilization involves, first, applying base fertilizer in the growing medium, and second, topdressing during the growth period. Topdressing mostly uses liquid fertilizer or foliar fertilizer, and the concentration should be lighter than for other flowers. Orchids should have their growing medium changed once a year, and during the growth period topdressing can be applied sparingly, with attention to timing. Generally, in the growing season, you can topdress with fully decomposed dilute bean cake water at about 15%, or 0.1% urea fertilizer water plus 0.2% monopotassium phosphate fertilizer water, once every 15 to 20 days; from before flowering to the flowering period, you can spray the leaves 2 to 3 times with 0.2% monopotassium phosphate or plant ash water to promote the development of roots, stems, and flowers. Orchids have fleshy roots, so undecomposed fertilizer must not be applied, to avoid root rot.

3. Watering method

Watering orchids should be based on the species, growth condition, and local climate, and you should aim for moist but not wet, dry but not parched; do not water too much or too little, and grasp the principle of not dry in autumn and not wet in winter. In winter, when temperatures are low and the plants are dormant, watering should be controlled, generally once every 5 to 7 days, but Cymbidium sinense, which blooms in winter, needs more water;

In spring and autumn, water once every 2 to 3 days; in summer, when temperatures are high and orchids are in a period of vigorous growth, water on average 1 to 2 times a day. When watering, be careful to prevent water droplets from splashing onto the leaves, so as to avoid black spots that affect the ornamental effect. During the orchid's growth period, water should often be sprayed on the leaves, and in summer water should also be sprinkled on the ground around the flower pot to increase air humidity and promote the orchid's growth and development. For watering orchids, rainwater and snow water are best; if tap water is used, it should be stored for 2 to 3 days before use.

4. Temperature requirements

For potted orchids in the north, they should be moved indoors when the temperature drops to 5°C around the Frost's Descent solar term, and in the early period after being brought indoors, windows should be opened often to keep the air circulating. In winter, the room temperature is best kept at around 10°C. After Grain Rain, move them outdoors for care. The suitable temperature for orchid growth is 16 to 24°C. In winter, the indoor temperature is generally required to be relatively low, 10 to 12°C during the day and 5 to 10°C at night, and the temperature and humidity must not be too high; in summer the temperature should not exceed 30°C.

5. Light requirements

Orchids prefer shade and fear direct strong light, so shade must be provided in spring, summer, and autumn. For home orchid growing, to control the amount of light, it is best to place them on a balcony windowsill or under the eaves with bamboo blinds for shade, generally shading from 9 a.m. to before 6 p.m., and pulling the blinds open in the morning and after 6 p.m. so they receive scattered sunlight. In winter, they should be moved indoors to a place with visible scattered light, but direct sunlight should also be avoided. Among orchids, Cymbidium sinense has the strongest shade tolerance, followed by Cymbidium ensifolium, while Cymbidium goeringii and Cymbidium faberi have weaker shade tolerance.

6. Potting method

The environment for cultivating orchids should be well ventilated, humid, and pollution-free. The orchid pot should be a tall pot, thick at the top and narrow at the bottom, with multiple drainage holes, or with drainage holes in the pot wall. The orchid pot itself should also have ornamental value.

Because orchids grow slowly, they can be repotted once every 1 to 2 years after the flowers fade. When potting, first put about 3 cm of tile pieces, furnace slag, and so on at the bottom of the pot to help drainage. Then, put in a layer of growing medium, place the orchid seedling in the center of the pot, straighten the roots, and let them spread naturally. When the soil is filled to halfway, lift the orchid seedling gently while shaking the pot so that the soil and roots combine closely. When the soil is filled to 2 to 3 cm from the pot rim, gently press it firm with your hand. After planting, water thoroughly and place in a cool place, spraying water once each in the morning and afternoon, and after about 7 to 10 days move it to a shaded place with dappled light for care.

Orchid cultivation precautions are as follows:

(1) Orchids are mainly distributed in the southeast and southwest regions. They mostly grow wild in shaded spots under sparse forests in humid valleys and beside rocks, so they like a warm, humid climate, prefer shade and moisture, require a shade level of 70% to 90%, and fear high temperatures, dryness, and strong light.

(2) During orchid cultivation, withered yellow old leaves and diseased or pest-damaged leaves should be continually cut off to help ventilation. After flower buds emerge from the soil, each plant should keep one strong flower bud and the rest should be cut off, so as to avoid consuming too many nutrients and affecting next year's flowering. After the flowers fade, the flower stems should be cut off.

How to grow Cymbidium hybridum: cultivation methods and precautions / water more

Cymbidium hybridum, friends who have seen it should be impressed. Its flowers are huge and brightly colored, making people like it at first sight. In daily life, many people want Cymbidium hybridum, but many of them are beginners, so how to grow Cymbidium hybridum is a question everyone wants to know. For this, the editor has carefully compiled the cultivation methods and precautions for Cymbidium hybridum, very detailed, and friends who want to grow it should definitely take a look.

1. How to grow potted Cymbidium hybridum: understand its habits

Growing Cymbidium hybridum indoors is not like outdoors; its growing environment all needs to be created by us, so for how to grow Cymbidium hybridum at home, we must first understand its growth habits and then meet them as much as possible. For this, the editor brings you the cultivation methods and precautions for Cymbidium hybridum from aspects such as soil, light, and water and fertilizer. Let's read on.

2. Cultivation methods and precautions for Cymbidium hybridum

1. Pot and soil selection

To grow Cymbidium hybridum indoors, you first have to choose the pot and soil. Of course, many people just buy potted plants directly, but to make Cymbidium hybridum grow well, you should still prepare the pot and soil yourself. The specific pot and soil selection is as follows:

Soil: According to the growth habits of Cymbidium hybridum, we should choose loose, airy, well-drained soil. The editor recommends using a mixed soil of moss, charcoal crumbs, fern roots, charcoal, bark pieces, broken bricks, and so on; it is best not to use ordinary growing medium.

Flower pot: The pot for planting Cymbidium hybridum should preferably be a ceramic flower pot with many holes on all four walls and a diameter of 15 cm, and 3-4 plants can be planted per pot.

2. Light

How to grow Cymbidium hybridum, light is naturally indispensable. Compared with other orchids, Cymbidium hybridum likes light relatively more, but cannot receive direct sunlight, so when growing it indoors, the pot should be placed in a spot with bright scattered light.

Precautions: Cymbidium hybridum fears strong light. In spring and autumn it should be shaded 40% to 50%, in summer shaded 60%, and after late autumn it should receive more light to help Cymbidium hybridum bloom.

3. Temperature

In the cultivation methods for Cymbidium hybridum, temperature is also very important. It is understood that Cymbidium hybridum likes a warm environment, and the indoor temperature should be kept at 15-25°C, which is good for plant growth.

Precautions: Once the temperature is below 10°C or above 35°C, Cymbidium hybridum will enter a dormant state. And to help Cymbidium hybridum overwinter safely, it is best to set the indoor temperature above 10°C.

4. Watering

Cymbidium hybridum likes a humid environment, so it requires more water. Especially in summer, not only should the watering amount be sufficient, 2-3 times a day, but the leaves also need to be sprayed with water, which can both prevent yellow leaves from appearing and effectively lower the temperature, while good ventilation should also be maintained.

Precautions: When watering Cymbidium hybridum, you should grasp the watering principle of “water thoroughly when dry.” Once watering is insufficient, the swollen pseudobulbs will shrivel and normal growth will be affected. In addition, watering should be reduced during the flowering period, otherwise brown spots will appear on the flowers.

5. Fertilizing

After watering, let's talk about fertilizing, which is also a very key part of the cultivation methods for Cymbidium hybridum. It is understood that Cymbidium hybridum likes fertilizer; in spring and summer, fertilize once every 5 to 7 days, in autumn fertilize once every 10 to 15 days, and in winter fertilizing can be stopped.

Precautions: At the seedling stage and in low-temperature seasons, organic fertilizer should be applied sparingly or not at all; in addition, the plant must not lack nutrients, otherwise Cymbidium hybridum leaves are prone to turning yellow and even falling off.

6. Pest and disease control

If, during the cultivation process, you do not strictly follow the cultivation methods for Cymbidium hybridum to care for it, Cymbidium hybridum is prone to attacks by pests and diseases. Among them, diseases include: leaf blight, anthracnose, soft rot, and leaf spot, and pests include: aphids, red spiders, scale insects, and so on. Once discovered, everyone should spray pesticide for control. As for exactly what pesticide to spray, there is a detailed introduction in the pest and disease control for Cymbidium hybridum, so it will not be discussed further here.

7. Potting and repotting methods

In the process of growing Cymbidium hybridum, besides paying attention to pests and diseases, everyone should also repot it at the appropriate time. When the plant is too large, it should be repotted or divided and potted (carried out after flowering or in early spring when new shoots have just sprouted), to promote growth and flowering.

Repotting method: 1. Take the Cymbidium hybridum out of the old pot, cut off rotten roots and yellow leaves, and wash off the old soil; 2. In the bottom of a large new pot, place a layer of broken tiles or broken bricks to help drainage and ventilation; 3. Put the treated Cymbidium hybridum plant into the pot, fill in new substrate, press firm with your hand, and water thoroughly.
