Crab claw orchid, also known as crab claw orchid, crab claw lotus and fairy finger flower, belongs to crab claw orchid of cactus family. Tender green, reddish new stem nodes, round main stem, easy to lignify, with many branches and nodes. There are bristles on the thorn base, and peanuts are on the thorn base at the top of the stem node. Common cultivated varieties are scarlet, pink, apricot yellow and pure white. Because the middle diameter is connected, it is shaped like a crab's auxiliary claw. The leafy stems are flat and knobby, plump, ovoid, bright green, truncated at the top and coarsely serrated at the edge. Peanuts are at the top of the stem, and the perianth is open and rolled back. Colors are lavender, yellow, red, pure white, pink, orange and bicolor.
Potting: When the seedlings are potted, put 2-2 cm thick coarse-grained substrate or ceramsite as the filter layer at the bottom of the pot, sprinkle a layer of fully decomposed organic fertilizer with a thickness of about 65,438+0-2 cm as the base fertilizer, then cover a layer of substrate with a thickness of about 65,438+0-2 cm, and then put in plants to separate the fertilizer from the roots to avoid burning the roots.
The base of the upper basin can be one of the following. Vegetable soil: slag 3:1; Or garden soil: medium-coarse river sand: sawdust (shavings) 4:1:2; Or one of paddy soil, pond sludge and humus soil. Or peat+perlite+ceramsite =2 parts +2 parts+1 part; Vegetable garden soil+slag =3 parts+1 part; Peat+slag+ceramsite =2 parts +2 parts+1 part; Sawdust+vermiculite+medium coarse river sand =2 portions +2 portions+1 portion. After the basin is finished, water it once and maintain it in a slightly cool environment for a week.
Humidity management: I like dry air environment, rainy days last too long, and it is easy to be infected by germs. Afraid of rain, keep the leaves dry at night. The optimum air relative humidity is 40~60%.
Temperature management: the optimum growth temperature is 15~32℃, and it will enter a dormant state when the summer temperature is above 33℃. Avoid cold cream. The overwintering temperature should be kept above 65438 00℃. In winter, when the temperature drops below 7℃, it will go into hibernation. If the ambient temperature is close to 4℃, it will freeze to death.
Summer:
1, strengthen air convection and let the temperature in the body radiate;
2. Put it in a semi-shady place, or shade it by 50%;
3, give it a proper spray, 2~3 times a day.
Winter:
1, move to a bright indoor place for maintenance;
2, outdoors, you can wrap it in a film for wintering, but every two days when the temperature is high at noon, you should uncover it and let it breathe;
Lighting management: In summer, leaves will be more beautiful if they are maintained or shaded by 50% in a semi-shady place. Because the temperature is not very high in spring and autumn, it should be given direct sunlight to help it accumulate nutrients through photosynthesis. In winter, it should be maintained in a bright place indoors. Usually put indoors for maintenance, it should be placed near the southeast doors and windows to receive light. Every other month or one and a half months, it should be moved outdoors for maintenance for two months, otherwise the leaves will grow thin and yellow, and the new branches or petioles will be slender and in a state of collapse.
Fertilizer and water management: it has strong drought tolerance and can grow under dry environmental conditions, but this does not mean that it is not watered or fertilized; Its roots are afraid of water stains. If there is water in the flowerpot, or watering and fertilizing too frequently, it is easy to cause root rot. The principle of fertilizing and watering it is "wet and dry, dry thoroughly, no watering, drenched thoroughly", and avoid wetting the plants during the day when fertilizing and watering:
Spring and autumn: these two seasons are the peak seasons for its growth, and the fertilizer and water management cycles in the order of "flower treasure"-clear water-"flower treasure"-clear water, with interval outdoor maintenance for about 2-4 days and indoor maintenance for 3-6 days.
Summer: during the high temperature period in summer, it often enters a dormant state, requiring less fertilizer and water, and even controlling fertilizer and water. Fertilizer and water management shall be in the order of "Flower Treasure"-Clear Water-Clear Water-"Flower Treasure"-Clear Water-Clear Water, and the outdoor maintenance interval shall be about 3-5 days; If you keep it indoors for 4-7 days, the interval will be shorter in sunny days or high temperatures, longer in rainy days or low temperatures, or the watering time will be arranged in the morning or evening when the temperature is lower. Spray plants often, too. [5]
Winter: The winter dormancy period is mainly about fertilizer control and water control. The fertilizer and water management is circulated in turn according to "Huabao" > Clear Water-> "Huabao"-> Clear Water-> Clear Water, with an interval of about 7~ 10 day. The watering time should be arranged as far as possible at noon on sunny days when the temperature is high.
What are the cultivation methods and precautions of potted crab claw orchid?
Cultivation method of Crab Claw Orchid (basic knowledge necessary for cultivation) 1. Potting: When the seedlings are potted, first put broken tiles or ceramsite with a thickness of 1~2cm at the bottom of the pot as a filter layer, and sprinkle a layer of fully decomposed organic fertilizer as a base fertilizer with a thickness of about 1~2cm.
Cover with a layer of soil, which can be mixed with relatively fertile humus soil, peat and coarse sand, and keep the pH value at 5.5-6.5, then put in the plant to separate the fertilizer from the root system to avoid burning the root system. After the basin is finished, water it once and maintain it in a slightly cool environment for a week.
2. watering: watering should change with the season. Although winter is the growing season, watering is not suitable because of the low temperature, as long as the basin soil is kept moist, generally watering every 4~5 days 1 time.
The temperature is high in summer, although it is shaded, the soil in the basin is still easy to dry. Generally, it is 1~2 days watering 1 time. You can often spray water on the leaves in summer, which can not only prevent heatstroke and cool down, but also make the plants grow well.
Water every 2~3 days in spring and autumn 1 time. 3. Fertilization: Fertilization mainly takes place 9 ~ 10 months before flowering and 4 ~ 6 months after flowering.
Every 10 day, apply 1 time decomposed human excrement and urine and cake fertilizer water. Fertilization in spring promotes more branches and leaves, mainly nitrogen fertilizer; Fertilization is not suitable in summer, otherwise it will easily lead to rot; In autumn, phosphate fertilizer is the main fertilizer, which can differentiate flower buds.
Stop watering before fertilization and let the soil dry thoroughly, and the effect is better. Never use strong chemical fertilizer.
4. Temperature: The optimum temperature for the growth of Crab claw orchid is 15~25℃. You need shelter from the rain in summer, and it is best to put it under a well-ventilated windowsill or eaves gallery.
After autumn, you can move to a sunny place indoors for cultivation. It is best to keep the temperature at 65438 05℃ in winter. When it is lower than 5℃, it will grow poorly and even suffer from freezing injury.
On sunny days, you should bask in the sun. Large plastic bags can be used to cover plants in cold nights to prevent frostbite.
5. Illumination: Crab claw orchid is a short-day plant, which can bloom in February and March under the condition of 8~ 10 hour of light every day. 6. Pests and diseases: Usually pay attention to ventilation and light transmission to create a relatively dry environment. If necessary, chemical agents can be used for prevention and control, such as using 800 times of thiophanate-methyl solution or 0/000 times of kocide solution, and spraying 1 time every 7~ 10 days.
If scale insects are found, spray 1 times pyrethroid killing solution every 7 days or so.
Crabs catch orchids like this.
Points for attention in cultivation methods and home geomantic omen of crab claw orchid, commonly known as crab claw orchid, is a kind of plant popular with flower lovers.
However, we will still encounter many problems when cultivating crab claw orchid. Now I'd like to introduce you to the knowledge about the cultivation and grafting of Crab Claw Orchid. First, the crab claw orchid has a flat stem and sharp serrations on the edge.
The main difference between the fairy finger and the same ornamental species is that the edge of the fairy finger is wavy without sharp serrations, and there is a very small amount of brown fine fluff at the base of the thorn at the top of the stem node. The flowering period is 1 to February.
Peanuts are at the top of stem nodes, red or purplish red. I like warm and humid environment.
The optimum growth temperature is 15 to 20 degrees. Crab claw orchids are beautiful, and can be placed on a balcony or room windowsill or table with light and no rain, which is suitable for long-term storage in the bedroom.
Second, the cultivation method of Crabapple 1, and the flowerpot for Crabapple cultivation (1) is selected. Quality requirements of flowerpots: clay flowerpots, plastic flowerpots, porcelain flowerpots and pottery flowerpots are all acceptable, but clay flowerpots are better. In order to cooperate with home decoration, color-changing plastic flowerpots can be used for cultivation.
(2) The size of the flowerpot: Crab claw orchid should be cultivated in a pot with a crown diameter of two thirds. 2. Prepare potted soil cultivated by Crab Claw Orchid. Crab claw orchid likes fertile and loose soil.
Families can use the following formula as garden soil: humus soil: 3: 4: 3 for example; The ratio of peat soil: humus soil: sand: perlite is 4:2:2:2. After the soil is prepared, it is best to sterilize it at high temperature before use, or it can be sterilized in the sun.
3, the watering method of crab claw orchid cultivation crab claw orchid likes wet soil, avoid humidity. After the leaf buds germinate in spring, the amount of water can be gradually increased to keep the soil moist, and attention should be paid to dryness and wetness when watering.
Spring and autumn are the seasons when the crab claw orchid grows vigorously. In addition to watering, we should also regularly sprinkle water around plants to increase air humidity. When the temperature is high in summer, if the water supply is insufficient, the growth of the crab claw orchid will stagnate, so water should be paid attention to in summer, but the pot soil should not be too wet to prevent high temperature and high humidity from causing rot.
However, attention should be paid to spraying around it several times a day to strengthen ventilation, so as to achieve the purpose of humidification and cooling. Pay attention to watering the wetlands between dry areas after the temperature gets cold in late autumn.
When the temperature is low in winter and early spring, the growth is slow, and the basin soil should be in a dry state. 4. Fertilization method of crab claw orchid cultivation Crab claw orchid likes fertilizer. When fertilizer is sufficient, there are many branches and flowers.
After bud germination, the crab claw orchid began topdressing. In the growing season, you can use 100 times of decomposed liquid fertilizer to mix 1000 times of potassium dihydrogen phosphate solution or 1000 times of general fertilizer, and topdressing every 15 ~ 20 days. Fertilization frequency should be reduced in late autumn, and fertilization should be stopped when the temperature is lower than 10 degrees.
High temperature in summer, low temperature in winter, no fertilization. Fertilize crab claw orchid carefully, not coarsely.
When applying fertilizer, slowly apply it along the edge of the basin with a fine nozzle. Don't splash the fertilizer solution on the leaves, otherwise it will burn easily. 5. The illumination of crab claw orchid culture requires that crab claw orchid be afraid of heat and high temperature to avoid exposure and rain, so it should be placed in a ventilated place indoors or on a cool balcony in summer.
After beginning of autumn, the crab claw orchid gradually recovered and should be placed in a place with 50% light, such as a shade shed or a sunny window, to receive light and promote flower bud differentiation; As the weather turns cold, the light should be gradually increased, and sufficient light should be given from late autumn to winter. 6. Four seasons management of crab claw orchid culture (1) Spring management Change pots before germination in early spring every year.
Young plants change pots every year 1 time, and adult plants change pots every two to three years 1 time. Before changing pots, stop watering for 2-3 days, let the pot soil dry thoroughly and then remove it. Pay attention to handle it with care to prevent it from being broken.
The new species of crab claw orchid is not watered for the time being, only sprayed 2 to 3 times a day or placed in a place with high humidity, and watered a little after 7 days. After the leaves germinate, they can increase water and keep the soil moist.
After changing pots in spring, arrange them on sunny windowsills. After the temperature rises, it will start to grow again, and the watering amount can be gradually increased to keep the basin soil moist. Pay attention to dryness and wetness when watering. When the outdoor temperature is stable above 15 degrees, it can be placed on the balcony with light but no rain.
Pay attention to the supply of water and fertilizer in the peak season, but avoid the soil being too wet. It is advisable to water the soil after it is dry. In rainy days, you should reduce the number of watering.
The temperature is high in late spring, so it is necessary to cover the noon light or move it to a semi-light place for cultivation. (2) In summer, the management of Crab Claw Orchid is not tolerant to sunlight, so it should be cultivated on a semi-shady windowsill or balcony in summer, or indoors with bright light.
Maintain adequate water supply. The temperature is cool at the end of summer, so the water supply can be gradually increased and topdressing can be resumed.
(3) Crab claw orchids managed in autumn should be cultivated in places with morning and evening light. Water the soil as soon as it is dry, and pay attention to spray to supplement the air humidity.
Pay attention to the supply of water and fertilizer after budding. When the temperature drops to about 65438 00℃, it should be moved into a closed balcony or a room with light in time to reduce the number of fertilization.
Because the bud is easy to fall off, care should be taken to prevent it from being knocked off when handling. (4) Crab claw orchid is not cold-resistant in winter, and the indoor temperature should be kept above 10℃ in winter.
Crab claw orchid should be cultivated on a well-lit windowsill or balcony, and should not be watered frequently. When the soil is dry, water it, not fertilize it. (5) Flowering period management: After flowering, if the crab claw orchid is moved to a room with scattered light at 5-8℃, the flowering period can be prolonged, and it is not advisable to water it too much. It is wise to water the soil after it is dry.
7. Precautions for Cultivation of Crab Claw Orchid (1) Crab Claw Orchid should be placed in a sunny place indoors after cool autumn. If there is insufficient sunshine in autumn and winter, the formed buds will fall off, and the flowering will be reduced or not.
(2) When the growth of Crab Claw Orchid is large, it is easy to be top-heavy, and it needs to be bound with scaffolding, which can be supported by wire and other things. After flower decay, the residual flowers should be cut off together with the terminal flower stems, and attention should be paid to water control. After the new buds grow, water can be used to keep the basin soil moist.
(3) The upper pot soil of the grafted seedlings of Crab claw orchid can use 3 parts of humus soil, 4 parts of garden soil, 3 parts of river sand, and a small amount of organic fertilizer or bone meal as base fertilizer. Generally, change the basin every 1~2 years.
Changing pots should be done after the failure of flowers in spring. (4) early spring, crab claws.
Cultivation methods and matters needing attention of crab claw orchid in winter
1. Crab claw orchids are prone to root rot due to excessive watering or poor drainage. Therefore, it is best to plant it with clean and loose coarse sand mixed with peat and rotten leaves.
2. Too much fertilization and too high fertilizer concentration will easily lead to the rotten roots of Crab claw orchid, which will lead to the wilting of stems and the flowers falling off when it is half open. The principle of fertilization is to apply less and more.
In summer, many people think that plants and flowers need to drink more water, so they water too much. In fact, the crab claw orchid enters a semi-dormant state in summer when the light is particularly strong, and the watering frequency is reduced compared with that in spring and autumn. Never store water in flowerpots, otherwise it will cause root rot. 4. When the sun is hot in summer, it is best to shade 50%.
Move the crab claw orchid to a cool place. Indoor illumination can fully meet the normal growth of Crab claw orchid.
It is best to shade 50%. When it is a little warmer in spring and autumn, water the soil when the flowerpot is almost dry.
The principle of watering is "dry and wet, dry thoroughly, no watering, drenched thoroughly". The temperature drops in winter and spring, and the weather is cold. Generally, water is poured once every 7- 10 day.
6. When the sun is not good or the weather is cold, move the crab claw orchid to the balcony and other places with good light. And every one or two months, you should be outdoors for ten and a half months, otherwise the leaves will not grow full and yellow.
7. The suitable temperature for the growth period of Crab Claw Orchid is 18 to 23℃. The optimum flowering temperature is about 15℃, not more than 25℃, but lower than 10℃.
8. In autumn, the crab claw orchid enters the flowering period. In order to avoid damaging the flower buds due to the large temperature difference between day and night, it is necessary to move the crab claw orchid to a place with good indoor light, trim the flower shape and cut off the weak flower buds that are too dense. 9. Because the tap water at home is purified, if it is used to water flowers for a long time, it will have a bad influence on the growth of flowers. Therefore, I suggest you buy a small amount of ferrous sulfate, and the blending ratio is roughly water: ferrous sulfate =300:3. After fully dissolving, water the flowers.
Once every six months. 10. In the cultivation of crab claw orchid, sometimes four or five new branches will grow at the top of a node. In order to keep ventilation and photosynthesis, the two branches of 1 should be cut off.
1 1. When scale insects are seriously harmful, the damaged parts of leaves will appear yellow and white. It can be scraped off with bamboo chips or sprayed with pesticides.
12. When the crab claw orchid grows to a large size, it is necessary to insert a bamboo pole into the soil, tie the upper part into a 2-3-layer circular bracket, and tie the branches on the ring, so that the branches and leaves of the crab claw orchid can be easily fixed.
What are the cultivation methods and precautions of potted crab claw orchid?
Cultivation method of potted crab claw orchid
1. When the seedlings are potted, the coarse-grained substrate or ceramsite with a thickness of 2-2 cm should be placed at the bottom of the basin as the filter layer, and a layer of fully decomposed organic fertilizer with a thickness of about 1~2cm should be sprinkled on it, then a layer of substrate with a thickness of about 1~2cm should be covered, and then plants should be placed to separate the fertilizer from the root system.
2. The base of the upper basin can be one of the following. Vegetable soil: slag 3:1; Or garden soil: medium-coarse river sand: sawdust (shavings) 4:1:2; Or one of paddy soil, pond sludge and humus soil. Or peat perlite ceramsite =2 parts, 2 parts, 1 part; Vegetable garden soil residue =3 portions 1 portion; Peat residue ceramsite =2 parts, 2 parts, 1 part; Coarse river sand in sawdust vermiculite =2 parts, 2 parts, 1 part. After the basin is finished, water it once and maintain it in a slightly cool environment for a week.
3, like the dry air environment, rainy days last too long, easy to be infected by germs. Afraid of rain, keep the leaves dry at night. The optimum air relative humidity is 40~60%.
4. The optimum growth temperature 15~32℃, afraid of hot and muggy weather, the summer temperature above 33℃ will enter a dormant state. 5. In summer, the leaves will be more beautiful if they are maintained in a semi-shady place or shaded by 50%. Because the temperature is not very high in spring and autumn, it should be given direct sunlight to help it accumulate nutrients through photosynthesis. In winter, it should be maintained in a bright place indoors.
6. It has strong drought tolerance and can grow under dry environmental conditions, but this does not mean that it is not watered or fertilized. The principle of fertilization and watering is "dry and wet alternately, dry thoroughly, no watering, and drenched thoroughly".
Matters needing attention in cultivation of potted crab claw orchid
1, its root system is afraid of water damage. If there is water in the flowerpot, or watering and fertilizing too frequently, it is easy to cause root rot.
2. If it is kept indoors, it should be placed near the southeast doors and windows to receive light, and it should be moved outdoors for two months every month or one and a half months, otherwise the leaves will grow thin and yellow, the new branches or petioles will be slender, and the internodes will be elongated and in a state of collapse.
3. avoid cold cream. The overwintering temperature should be kept above 65438 00℃. When the temperature drops below 7℃ in winter, it will go into hibernation. If the ambient temperature is close to 4℃, it will freeze to death. ?
Cultivation Methods and Precautions of Crab Claw Orchid Which cultivation techniques are important?
The propagation methods of crab claw orchid are divided into grafting and cutting, and people often use grafting to propagate.
Cactus is a commonly used grafting theme. When grafting, cut a hole in the cactus that is consistent with the incision of the crab claw orchid. It is best to go down across the board and be uniform. Then connect and fix the rootstock and scion by hand for about half a minute. Then connect the cactus thorn with the crab claw orchid, which can be better combined. Finally, water in the shade regularly and wait for growth.
Cutting is to directly break off a part of the crab claw orchid from the mother body and insert it into the soil, preferably with buds, so as to accelerate the growth of the crab claw orchid. Pay attention to timely drainage during breeding period. If the soil where the crab claw orchid is planted is too wet, it will lead to root rot, so it is best to choose sandy soil for planting.
And the frequency and quantity of fertilization should not be too much, which will also lead to the root rot of crab claws, which is not conducive to the growth of crab claws. Generally speaking, it will be interesting to fertilize once a month.
In terms of watering, the number of watering in summer is less than that in spring and autumn, because too high temperature will slow down the growth of crab claw orchid and absorb less water. Generally, water is poured every ten days in spring and autumn.
Moreover, the crab claw orchid should be placed in a cooler place in summer and in a place with sufficient light in winter.
Cultivation methods and precautions of crab claw orchid When is the natural flowering period of crab claw orchid?
First, the cultivation method of Crab claw orchid
1, upper basin:
When the seedlings enter the pot, put the broken tiles or ceramsite with a thickness of 1~2cm into the bottom of the pot as a filter layer, and sprinkle a layer of fully decomposed organic fertilizer as a base fertilizer with a thickness of about 1~2cm. Cover with a layer of soil, and you can mix in relatively fertile humus soil, peat and coarse sand, keep the pH value between 5.5 and 6.5, and then put in the plants. The fertilizer should be separated from the roots to avoid burning the roots. After the basin is finished, water it once and maintain it in a slightly cool environment for a week.
2. Water:
Watering should change with the seasons. Although winter is the growing season, watering is not suitable because of the low temperature, as long as the basin soil is kept moist, generally watering every 4~5 days 1 time. The temperature is high in summer, although it is shaded, the soil in the basin is still easy to dry. Generally, it is 1~2 days watering 1 time. You can often spray water on the leaves in summer, which can not only prevent heatstroke and cool down, but also make the plants grow well. Water every 2~3 days in spring and autumn 1 time.
3, fertilization:
Fertilization is mainly carried out 9- 10 before flowering and 4-6 months after flowering. Every 10 day, apply 1 time decomposed human excrement and urine and cake fertilizer water. Fertilization in spring promotes more branches and leaves, mainly nitrogen fertilizer; Fertilization is not suitable in summer, otherwise it will easily lead to rot; In autumn, phosphate fertilizer is the main fertilizer, which can differentiate flower buds. Stop watering before fertilization and let the soil dry thoroughly, and the effect is better. Never use strong chemical fertilizer.
4. Temperature:
The optimum temperature for the growth of Crab claw orchid is 15~25℃. You need shelter from the rain in summer, and it is best to put it under a well-ventilated windowsill or eaves gallery. After autumn, you can move to a sunny place indoors for cultivation. It is best to keep the temperature at 65438 05℃ in winter. When it is lower than 5℃, it will grow poorly and even suffer from freezing injury. On sunny days, you should bask in the sun. Large plastic bags can be used to cover plants in cold nights to prevent frostbite.
5. Lighting:
Crab claw orchid is a short-day plant, which can bloom in February and March under the condition of 8~ 10 hours of light every day.
6, pests and diseases:
Usually, we should pay attention to ventilation and light transmission to create a relatively dry environment. If necessary, chemicals can be used for prevention and control. Such as thiophanate methyl 800 times solution or chlorhexidine 1000 times solution, sprayed every 7~ 10 days/time. If scale insects are found, spray 1 times pyrethroid killing solution every 7 days or so.
Second, the matters needing attention in cultivating crab claw orchid
1. Crab claw orchid has a dormant period after flowering. At this point, the basin soil should be kept slightly dry. After dormancy, normal watering management can be carried out when new buds grow at the top of stem nodes.
2. Crab claw orchid should not be exposed to the sun, because direct exposure will burn the plant, leading to stem and leaf withering and even death. So summer must be shaded.
3. Crab claw orchid is semi-cloudy, so it should be cultivated indoors in sunny place or balcony in spring, and pay attention to proper ventilation.
3. The flowering period of Crab Claw Orchid is 1 1~ 1, and the management of flowering period is as follows:
1, control water and stop fertilizer
water
Crab claw orchid is particularly sensitive to water during flowering, and it is easy to drop buds and even rot rootstocks when watered too much. Without water, flowers will wither and buds will not grow normally. The correct watering method is: keep the pot soil slightly wet and knead it by hand. At noon, it can be sprayed with water similar to that in a greenhouse. If the soil in the basin is too dry, do not water it at once, but step by step.
obese
Crab claw orchid likes fertilizer, so it should be fertilized according to the principle of thin fertilizer and diligent application during its growth. But generally speaking, fertilization is applied before flowering, and fertilization is stopped after the bud is basically formed.
2, heat preservation and luster
When the flowering temperature is controlled between14 and 20℃, the buds can't develop normally at low temperature, and the plants are easy to die of frostbite when it is lower than 5℃. If the temperature is too high, it is easy to shorten the flowering period.
Crab claw orchid is a short-day plant, but its flowering period needs to be strengthened. Put the plants on the sunny balcony and turn over the pots every 7 days to make the plants bloom evenly. When the indoor light is insufficient or cloudy, fluorescent lamps can be used to fill the light, and the lights are turned on for 3~4 hours every evening before the flowers can bloom normally.
3. Ventilation and pest control
The taboo of planting flowers in winter is to keep the plants in the greenhouse and ignore the ventilation. Poor ventilation and humid air can easily lead to diseases and insect pests. When the weather is clear, it is necessary to properly open the window for ventilation.
Aphids and scale insects are the main pests of crab claw orchid at flowering stage. In addition to paying attention to ventilation, if pests occur, it is necessary to catch or spray omethoate solution manually in time!
How to raise begonia begonia, cultivation methods and matters needing attention.
Pay attention to the moisture of the soil after sowing, and it will germinate in about a week. However, if the crab claw orchid grows naturally, it will take several years to blossom. In order to make the crab claw orchid blossom faster, grafting is usually chosen. After grafting, it needs to be placed in a ventilated environment to avoid direct sunlight, and it can grow normally in about half a month. Crab claw orchid is very fertile. If you break off a piece of crab claw orchid and insert it in the soil, it will be easy to survive.
?
It is most suitable to keep the pH value of the soil for cultivating begonia at about PH5.5, and fertile soil is very helpful for the growth and flowering of begonia. Crab claw orchid absorbs less water and does not need a lot of watering. It can be watered once every four days in spring and autumn, once every two days in high temperature in summer and once a week in cold winter. Flower fertilizer is generally sold in the flower market, and it is enough to fertilize the crab claw once a week. If it is in the flowering and dormancy period of crab claw orchid, there is no need to continue fertilization.
?
Several problems that should be paid attention to in the cultivation of crab claw orchid. Crab claw orchid has strong phototropism, so don't move it frequently when cultivating it, which will have a great influence on its growth and flowering. The pH value of the soil in which the crab claw orchid is cultivated should be well controlled. Clara loves acidic soil, and the tap water at home is alkaline. It is best to change the pH of soil with ferrous sulfate every half month. Crab claw orchid will gradually enter the dormant period after summer, so it is necessary to add fertilizer in time to ensure that crab claw orchid has enough nutrients during the dormant period. Crab claw orchid is afraid of cold, so it is best to move indoors in winter.
