Is Calathea makoyana poisonous? Introduction to hydroponic methods and flowering

 Calathea makoyana is good-looking, and its high ornamental value makes it willful; everyone likes it. Calathea makoyana can be grown not only in soil but also hydroponically. What is the hydroponic method? Will Calathea makoyana bloom? Is it poisonous?

Hydroponic method for Calathea makoyana:

For hydroponics, generally use perlite and vermiculite at 1:1, and it is best to add a little expanded clay pebbles. Spread a layer of expanded clay pebbles at the bottom of the pot for good drainage and to stabilize the plant. Fill the pot with the medium to at least eight-tenths full, and add expanded clay pebbles on top as well to stabilize the plant.

Choose a small Calathea makoyana plant, wash the root system clean, cut off the withered roots, then soak it in a potassium permanganate solution mixed with water for about 10 minutes, wash it clean again, add clear water to the medium just prepared, and plant it.

At the beginning of hydroponics, the leaves will curl. As long as it is kept in a ventilated, shaded place, with appropriate misting onto the leaf surface, and the clear water is changed once every 1-2 days, the leaves will always recover, and new roots will appear after 10 days.

When the plant has fully adapted to the hydroponic environment, a foliage-type nutrient solution can be added, replacing the nutrient solution once every 3-4 weeks, and misting water regularly.

Is Calathea makoyana poisonous?

Calathea makoyana is not poisonous and can be grown with peace of mind; it can also absorb indoor formaldehyde.

Does Calathea makoyana bloom?

Calathea makoyana does bloom.

Sometimes we find that a layer of dust accumulates on Calathea makoyana. How do we restore its luster? Just use a soft cloth or a kitchen wet wipe dipped in warm water and carefully wipe it clean.

What should be done if the leaf edges scorch?

This is generally caused by environmental humidity being too low. Usually maintain a certain level of environmental humidity and mist it more often; of course, do not expose it to too much sun.

What should be done if the leaves decline and look unattractive?

This situation is generally caused by insufficient light and too much shade. Slowly move it to a place with sufficient light. Although it is fairly shade-tolerant, it cannot stay in dark places for a long time, especially in places that are not ventilated.

Appearance of disease spots:

This is generally caused by waterlogged potting soil and a stuffy, hot environment. Pay attention to ventilation, and if the potting soil is poor, choose a good time to replace it!

I.At home, grow different flowers according to different growing environments
1. Entrance hall
The entrance hall is the entrance area of a residence, including corridors and passageways. The decoration of the entrance hall should give people a first impression and feeling, whether luxurious and romantic, neat and solemn, or elegant and concise, all of which can be felt from the decoration of the entrance hall.
The entrance hall space of a residence is often relatively narrow, and some are just a corridor passageway. It is the necessary passage to the living room, and most of it is relatively dim. For the greening decoration here, plants with neat forms or climbing columnar shapes are mostly chosen, such as Brazilian iron, Aspidistra, and golden pothos; spider plants, ferns and other plants are also often used, in hanging form, which can save space and enliven the atmosphere of the space. In short, the plants selected for the greening decoration here are preferably fine-leaved and soft-stemmed, to soften the line of sight in the space.
2. Living room
The living room is the main place for daily life, the center of family activities, and also the main place for receiving guests, so it has multiple functions and is the focus of greening decoration in the entire residence. To some extent, the degree of decoration in the living room can show the owner's identity, status, and interests. The greening decoration of the living room should reflect a hospitable and happy atmosphere. Plant arrangement should highlight the key points and avoid clutter, and should strive to be beautiful, generous, and solemn, while also paying attention to harmony with the style of the furniture and the color of the walls. If a luxurious and imposing effect is required, plants with larger leaves and taller forms can be chosen, such as Pachira aquatica, Brazilian iron, and Philodendron giganteum as the main plants, or vines such as areca palm, weeping fig, golden pothos, and Philodendron 'Imperial Green' as the main scene; if an elegant and antique effect is required, tree-stump bonsai can be chosen as the main scene.
But no matter what is used as the main scene, a small pot of brightly colored, small and exquisite foliage plants must be placed on the coffee table, flower stand, or window frames and small tables near the sofa, such as ornamental bromeliads, Calathea makoyana, and Alocasia cucullata; if necessary, fresh flowers or seasonal flowers can also be placed on the small tables. Such a combination not only highlights the theme of the living room layout, but also keeps the room evergreen all year round and full of vitality.
3. Study
The study is a place for reading, writing, and sometimes also for receiving guests. The greening decoration of the study should be bright, fresh, and elegant, thereby creating a quiet, peaceful, and elegant environment, so that people feel calm and tranquil upon entering and can concentrate. Therefore, the plant arrangement in the study should not be too eye-catching, but should choose plants with colors that are not dazzling and forms that are relatively ordinary, reflecting a restrained style. Generally, a pot of light and elegant asparagus fern or green plants such as watermelon pilea or Syngonium can be placed on the writing desk to regulate eyesight and relieve fatigue; hanging plants with spreading and drooping forms can be chosen, such as golden pothos, heartleaf philodendron, English ivy, and inch plant, hung in the corner of the wall, or allowed to trail down from the top of a bookcase; a suitable position can also be chosen to place a pot of climbing plants, such as fiddle-leaf philodendron, golden pothos, and Philodendron domesticum, like a coiled dragon soaring into the air, giving people the passion to strive upward and work hard.
4. Bedroom
The main function of the bedroom is sleep and rest. About 1/3 of a person's life is spent sleeping, so the arrangement and decoration of the bedroom are also very important. The plant arrangement in the bedroom should revolve around the function of rest, and plant decoration should create an atmosphere that can soothe nerves, relieve fatigue, and relax people. At the same time, because there is more furniture in the bedroom and the space appears crowded, the plants chosen are preferably small and light green. Matching bonsai should also not have bright colors or peculiar shapes. Asparagus fern, Monstera deliciosa, ferns, etc. can be placed on the desk or stands. If space permits, plants with neat forms can also be placed on the floor, such as heartleaf philodendron, Brazilian iron, and schefflera. In addition, plants can also be selected according to the age and personality of the residents.
5. Dining room
The dining room is a place for family members or guests to dine or gather. When decorating, the theme should be sweetness and cleanliness, and appropriately placing brightly colored indoor foliage plants is suitable. At the same time, fully consider saving space and mainly use three-dimensional decoration. In principle, the selected plants should be small in form. For example, on a multi-tiered flower stand, display several small, exquisite, lush green indoor foliage plants (such as ornamental bromeliads, Peperomia, Monstera deliciosa, lily grass, Calathea makoyana, asparagus fern, and Pilea cadierei, etc.), or place a clearly formed indoor foliage plant in the corner, such as golden pothos, Pachira aquatica, and Yucca elephantipes. In this way, people can feel energized and their appetite can increase.

II.At home, grow different flowers according to different home feng shui
1. Lucky bamboo
Lucky bamboo is also called "ten-thousand-year bamboo" and "evergreen." It is a widely popular "money tree." Growing lucky bamboo at home symbolizes attracting wealth.
2. Kumquat
Growing kumquat at home has the meaning of gold and silver treasures and is quite helpful for increasing financial resources. But note: do not pull the kumquat off, and clean up dead branches and fallen leaves frequently.
3. Narcissus
Growing narcissus at home can ward off evil and remove filth, bring good fortune and auspiciousness, and can also attract wealth. Keep in mind: before narcissus blooms, it looks like a large scallion, so keeping it fresh is very important.
4. Chrysanthemum
Growing chrysanthemums at home symbolizes longevity and increased blessings, and helps with the feng shui keyword of indoor decoration for aura and magnetic field. But note: both Shasta daisies and cosmos are suitable for placing at home, but pay attention to sunlight and also watch out for pests. In addition, growing flowers such as jasmine, clove, honeysuckle, and morning glory at home releases bactericidal substances that can kill certain bacteria in the air, inhibit the occurrence of diphtheria, tuberculosis, dysentery pathogens, and typhoid bacteria, and keep indoor air clean and hygienic.

III.At home, grow different flowers according to different flower functions and effects
Generally, the number of flowers and plants placed in the hall should be controlled within 3 pots. In terms of varieties, it is best to choose some plants with low light requirements, such as evergreen, Brazilian iron tree, and Chinese orchid types; in the bedroom, it is best not to place flowers and plants. If they must be placed, some small and exquisite succulent plants such as cactus and cactus ball can be chosen as embellishment.
Aloe, spider plant, and snake plant can remove formaldehyde. In a 15-square-meter room, planting two pots of snake plant or spider plant can keep the air fresh and free from the harm of formaldehyde. Snake plant can also release a large amount of oxygen during the day. Spider plant can also release bactericidal substances and kill bacteria. If enough spider plants are placed in a room, 80% of harmful substances will be killed within 24 hours; spider plant can also effectively absorb carbon dioxide.
1. Plants that can kill bacteria
The volatile oils produced by aromatic flowers such as rose, osmanthus, violet, jasmine, lemon, rose, dianthus, lily of the valley, and crape myrtle have significant bactericidal effects.
Plants such as crape myrtle, jasmine, and lemon can kill native bacteria such as diphtheria bacteria and dysentery bacteria within 5 minutes. The fragrance emitted by plants such as rose, dianthus, lily of the valley, violet, rose, and osmanthus has a clear inhibitory effect on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus, and Staphylococcus.
Succulent plants native to tropical arid regions, such as cactus, have stomata on their fleshy stems that close during the day and open at night. While absorbing carbon dioxide, they produce oxygen, increasing the concentration of negative ions in indoor air.
Plants such as snake plant, Sansevieria, Agave, Opuntia, Kalanchoe, Sedum, Bryophyllum, and cultivated bromeliads can also purify the air at night.
Planting climbing plants such as Boston ivy, grape, morning glory, wisteria, and rose around the home and letting them climb along walls or trellises to form a green shade canopy can effectively reduce solar radiation and greatly lower indoor temperature. Plants such as clove, jasmine, rose, violet, and mint can make people relax, feel happy, help with sleep, and also improve work efficiency.
Many people like to grow flowers indoors to improve and beautify the indoor environment, but if chosen improperly, it can instead cause indoor pollution. Therefore, when growing flowers, note: choose good varieties. The most suitable indoor choices are evergreen flowers and trees or varieties that can absorb toxic gases, such as spider plant, asparagus fern, evergreen, cactus, Monstera deliciosa, and English ivy.
2. Aromatic effects of common flowers
Rose fragrance: relaxes nerves, relieves physical and mental fatigue, and helps treat nervous system diseases.
Tulip: can relieve eye fatigue and eliminate irritability.
Orchid fragrance: relieves lung heat and phlegm cough, and is beneficial to people with neurasthenia, but it should not be too strong, otherwise it can also cause dizziness.
Michelia alba fragrance: can sterilize and purify the air.
3. Plants that can absorb toxic chemical substances
Aloe, spider plant, snake plant, Aspidistra, and Monstera deliciosa are natural scavengers and can remove harmful substances from the air. Studies have shown that snake plant and spider plant can absorb more than 80% of harmful gases indoors, and their ability to absorb formaldehyde is especially strong. Aloe is also good at absorbing formaldehyde and can absorb 90% of the formaldehyde contained in 1 cubic meter of air. English ivy, sago palm, chrysanthemum, kumquat, pomegranate, Portulaca grandiflora, Chinese rose, camellia, pomegranate, Aglaia odorata, daisy, wintersweet, and marigold can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, and nitrogen peroxide. Orchid, osmanthus, wintersweet, Caladium bicolor, and Excoecaria cochinchinensis are natural dust removers; their cilia can intercept and absorb floating particles and smoke dust in the air.
4. Plants that can resist radiation
If you place one or two pots of cactus beside your computer, it can help the human body absorb as little of the radiation released by the computer as possible. Because cactus grows in places with strong sunlight, its ability to absorb radiation is especially strong.
(1) Cactus (cactus ball) can resist radiation
Cactus and succulent plants have a nickname: "lazy person's plants." This type of plant requires little care and attention for cultivation, and hydroponic cactus ball is even easier to maintain. Because cactus (cactus ball) grows in places with strong sunlight, its ability to resist ultraviolet and other radiation is especially strong. Hydroponic cactus ball is clean and environmentally friendly, with no peculiar smell. If you place one or two pots of hydroponic cactus (cactus ball) beside your computer, it can help the human body absorb as little of the radiation released by the computer as possible. Because cactus (cactus ball) grows in places with strong sunlight, its ability to absorb radiation is especially strong.
(2) Cactus ball, called a nighttime "oxygen bar"
Cactus ball mostly respires at night when it is relatively cool and humid. During respiration, it inhales carbon dioxide and releases oxygen. Therefore, placing a large golden barrel cactus indoors is like adding an air freshener and can purify indoor air. Thus it is also an ideal flower for indoor display at night.
(3) A master at absorbing dust. Do not underestimate the cactus ball; it is also a master at absorbing dust! Placing a cactus ball indoors, especially a hydroponic cactus ball (because hydroponic cactus ball is cleaner and more environmentally friendly), can play a role in purifying the environment.
5. Recommended flowers to grow at home
(1) Aster, Astragalus, Nicotiana, and cockscomb; these plants can absorb large amounts of radioactive nuclides such as uranium.
(2) English ivy, Chinese rose, rose, aloe, and evergreen can effectively remove indoor trichloroethylene, hydrogen sulfide, benzene, phenol, hydrogen fluoride, and ether, etc.
(3) Eucalyptus, asparagus fern, Euphorbia, and cactus can kill bacteria; asparagus fern can also remove heavy metal particles.
(4) English ivy, fig, Philodendron bipinnatifidum, and common aloe can not only deal with bacteria and other harmful substances brought in from outdoors, but can even absorb dust that is difficult for even a vacuum cleaner to catch.
(5) Monstera deliciosa, snake plant, and Aspidistra can absorb more than 80% of harmful gases indoors.
(6) Citrus, rosemary, and spider plant can greatly reduce bacteria and microorganisms in indoor air.
(7) Chinese rose can absorb relatively large amounts of harmful gases such as hydrogen sulfide, benzene, phenol, hydrogen chloride, and ether.
(8) Wisteria has strong resistance to sulfur dioxide, chlorine, and hydrogen fluoride, and also has a certain resistance to chromium

IV.Different plants are placed in different rooms at home
1. Bedroom
Medium and small pots or hanging pots should be mainly used. It is suitable to place one pot of light-colored fragrant plants such as jasmine, osmanthus, Chinese rose, and banana shrub, or to place plants with small leaves such as asparagus fern and zebra plant. Flowers that are too brightly colored make it difficult for people to sleep and are not suitable for placement. Bedroom flowers are generally smaller in form, and the plant growing medium should preferably use sphagnum moss instead of soil to keep the room clean. The shape of the containers holding the plants should not be peculiar, so as to maintain a peaceful and calm atmosphere in the bedroom.
2. Study
The main focus should be quietness. In greening and beautifying arrangements, it should be beneficial to study, research, and creation. A large study can be equipped with a curio cabinet, with books, small ornaments, and potted clivia and landscape bonsai placed on it, creating an artistic and elegant reading environment.
3. Living room
First of all, focus on decorative beauty. The number should not be too many, and attention should be paid to combining medium and small plants. In a large living room, large and medium-sized foliage plants such as broadleaf lady palm, sago cycad, rubber tree, or fern can be placed beside the sofa or in idle space; in a small living room, small plants or trailing plants can be chosen, such as English ivy and spiderwort. In addition, they should be placed against the wall corners so as not to hinder people's movement. The living room is generally mainly based on bonsai. Some small bright potted flowers, plum blossoms, or plant bonsai can be placed on the coffee table. In the room, the contrast between sizes and between flowers and leaves sets off the lively vitality of the living room.
4. Dining room
Greening plant decorations that make people feel happy and can increase appetite should be chosen. For example, begonia and poinsettia, etc., to add a cheerful atmosphere. Placing medium-sized potted plants on the serving table has a spacing effect. Bright green potted plants can all be placed around the dining room. In the center of the dining room, spring orchid, autumn chrysanthemum, summer perilla, and winter red (poinsettia) can be placed according to the season. A pot of spider plant can be hung above the dining table, looking "unrestrained" and romantic, making people's appetite greatly increase.
5. Kitchen
Usually located in a north-facing room with fewer windows, decorating with some potted plants can eliminate the feeling of cold. Small potted plants should be mainly used, and hanging potted plants can be chosen, among which hanging spiderwort is better, followed by spider plant. Small flowers such as fringed iris and snake plant can be placed at the windowsill. Vegetables not eaten for the time being can also be used and placed in a uniquely shaped flower basket as a hanging decoration.
6. Bathroom
Most bathrooms in our country are not large in area and have poor lighting conditions. Plants with less strict light requirements should be chosen, such as pitcher plant, Pilea cadierei, and small fern types.
7. Balcony
With sufficient sunlight, it is suitable for brightly colored flowers and evergreen plants. Several pots of spider plant can also be hung, some flowering plants can be placed on the railing (such as camellia, kumquat, etc.), and foliage potted plants can be placed against the wall, setting each other off. Two pots of flowers (such as Chinese rose, autumn crocus, etc.) can also be placed on the balcony window, which both increases the overall beauty and fills it with a green atmosphere.

V.Common flowers and plants grown at home
1. Aloe
Growing aloe in pots at home can not only beautify the room, but also allow harvesting at any time to obtain the freshest aloe leaves for home health care. Some people say that growing a few pots of aloe at home is like inviting a resident "private doctor." Although this saying is somewhat exaggerated, it is not entirely unreasonable. Whether aloe is used as medicine to treat illness or for beauty and skin care, only fresh aloe can achieve the best results. Aloe has extremely high ornamental value.
Although the aloe's flowering period is short, its flowers are also very bright and colorful, making it very popular. Small potted aloes can be placed on a desk or writing table, while larger plants, once potted, can be placed in the courtyard and combined with other succulent plants to form a unique natural landscape full of interest. In winter, they can be moved into the main hall for indoor display. Aloe not only performs photosynthesis and releases oxygen during the day, but can also absorb indoor carbon dioxide at night, purifying the indoor air.
Aloe can effectively remove formaldehyde from the air. Planting a few aloes is like installing several "biological air purifiers" in the home, purifying the living environment at all times. When harmful gases in the air, such as carbon monoxide, carbon dioxide, sulfur dioxide and formaldehyde, remain at a high level for a long time and the aloe can no longer completely remove and absorb them, spots will appear on the leaves, alerting you to promptly take appropriate measures to avoid harm to human health from the harmful gases.
2. Spider plant
Native to South Africa, family Liliaceae. It has strong adaptability, is relatively drought-tolerant and cold-tolerant, prefers warmth and humidity, and is suitable for growing in loose, fertile, well-drained soil. The spider plant is one of the most traditional hanging plants for indoor spaces. Its leaves are slender and soft, and the trailing stems growing from the leaf axils bear small plantlets, hanging down from the edge of the pot, spreading and draping like flowers, evergreen all year round; it is both firm and soft, shaped like a crane spreading its wings and leaping, hence the ancient name "crane-fold orchid."
It is also known by other names such as pendulous pot grass, guilan and goulan, and in Western Europe it is also called spider grass or airplane grass. The spider plant is not only an excellent hanging foliage plant for indoor spaces, but also a good indoor air-purifying flower. The spider plant has an extremely strong ability to absorb toxic gases and can purify toxic gases such as carbon monoxide, carbon dioxide and formaldehyde. Generally, keeping 1 to 2 spider plants in a room can absorb nearly all the toxic gases in the air, so the spider plant also has the fine reputation of being a "green purifier."
Growing flowers and plants indoors can "create" a good microclimate. In modern buildings made with reinforced concrete precast panels, the air humidity is much lower than normal standards, almost the same as in a desert. But a plant called cyperus can turn a "desert" into an "oasis." Cyperus likes water, so potted cyperus should be placed in a deep water trough. Many flowers and plants suitable for indoor cultivation have bactericidal functions.
If some potted citrus, rosemary, myrtle, spider plants and so on are placed in a room, the bacteria and microorganisms in the air will be greatly reduced. People feel stifled in a stuffy room, and the reason is not a lack of indoor oxygen, but an extreme shortage of negative oxygen ions. When a television or computer is turned on indoors, negative oxygen ions rapidly decrease. There are many flowers and plants that can be grown indoors that can produce negative oxygen ions - these flowers and plants are cypress, Oriental arborvitae and Japanese cedar.
If the indoor area is too small, you might as well change the types and grow some low-growing plants, such as cacti. At present, growing spruce and other low-growing conifers on balconies is popular in the West; they can fill the room with a refreshing tree fragrance.
Placing some pollution-resistant flowers and plants in indoor spaces can also function as an air purifier. For example: ivy can "eat" benzene, spider plants can "devour" indoor carbon monoxide and formaldehyde, and the spathe of jack-in-the-pulpit can absorb benzene and trichloroethylene. If there is one pollution-resistant plant in a 10-square-meter room, it will greatly help air purification.

Six.Flowers unsuitable for growing at home
Flowers unsuitable for growing: lilac and night-blooming jasmine can release particles that irritate the sense of smell at night, having adverse effects on patients with high blood pressure and heart disease; the floral fragrance of oleander can make people drowsy and reduce intelligence; the particles released by hydrangea can cause skin allergies and itching; tulip flowers contain toxic alkaloids, and excessive contact can easily cause hair loss; the oily fragrance released by pine and cypress flowers and trees can affect people's appetite. Do not grow "mutually incompatible" flowers: when rose and mignonette are together, the mignonette will wither, but before withering the mignonette releases a substance that poisons the rose to death. Herbaceous flowers such as corn poppy, orchid, dianthus, stock and lily are difficult to get along with other flowers and plants, causing the plants to die.
Do not grow flowers in a sick person's room. The fungal spores produced by the soil in flower pots will spread into the indoor air, causing superficial or deep infections in the human body, and may also invade parts such as the skin, respiratory tract, external auditory canal, meninges and brain. For patients who are already ill and in poor health, this makes matters worse, and it is especially more harmful to leukemia patients and organ transplant recipients. Professor Li Zuowen, head of the expert group of the Liaoning Provincial Landscape Architecture Society, responded to these doubts. He believes that worry about "dumb cane" is unnecessary, as it is not among the 52 cancer-promoting plants. Although it is toxic, it can be grown with peace of mind. In fact, many flowers in residents' homes are toxic. Monstera is a natural scavenger and can remove harmful substances from the air, but it is also a toxic flower.
Pothos is evergreen all year round and can absorb toxic gases, but the sap of pothos is toxic; contact with the skin can cause redness and itching, and accidental ingestion can also cause throat pain; evergreen is in the Liliaceae family, and its toxic part is the rhizome; eating a large amount of the rhizome can cause symptoms such as nausea, abdominal pain, cold limbs and even coma. As for zebra evergreen, the sap of the leaves can make a person mute. Guo Xichang, a professor in the Department of Forestry at Shenyang Agricultural University, believes that plants in the Euphorbiaceae and Thymelaeaceae families are also toxic, such as the crown of thorns, one of the 52 cancer-promoting plants, and it is better not to grow them at home. However, there is absolutely no need to smash toxic flowers such as dumb cane and pothos that can purify the air at home.

Seven.Points to note when growing flowers at home
Experts believe that the proper attitude toward toxic plants is: keep an appropriate distance, do not casually play with or touch them; do not hold the branches, leaves or fruits in the mouth. Experts have also summarized 10 kinds of flowers that should be avoided as much as possible in the bedroom: for example, the fragrance of orchids can cause insomnia; mimosa may cause hair loss; the pollen of redbud can trigger asthma and worsen coughing; night-blooming jasmine can cause dizziness; the fragrance of lilies can cause insomnia; the fragrance of Chinese rose can make people feel depressed; the milky white liquid secreted by oleander can poison people; the fragrance of pine and cypress can make people lose appetite; hydrangea can easily cause allergies; tulip flowers can cause hair loss. As for what flowers are good to grow indoors in winter, the two professors also offered some suggestions: growing flowers indoors is not a case of the more the better. For a room of about 15 square meters, it is only suitable to place 2 medium or large plants, while 3 to 4 small plants can be placed.
