How to Grow Curly-Leaf Mint and How It Differs from Round-Leaf Pilea

Curly-leaf mint is also a kind of mint, and it really does look quite similar to mint. What are the growing methods for curly-leaf mint? What are the differences between curly-leaf mint and round-leaf pilea?

Growing methods for curly-leaf mint:

Curly-leaf mint is a slightly cold-tolerant plant, and a brief spell of low winter temperatures will not kill it; simply keep the minimum care temperature above 0°C.

When caring for curly-leaf mint in summer, you can shade it appropriately to avoid excessive direct sun. Also, water it more during high temperatures; you can water it thoroughly once a day to prevent the soil from becoming too dry.

Curly-leaf mint has a certain drought tolerance, so do not worry that the soil will become too dry and kill it. Once you see the leaves slightly wilted, you can still water it thoroughly, and it will quickly resume growth.

If you want a potted curly-leaf mint to grow more lushly as quickly as possible, you can prune it regularly. Whenever you see a longer stem, you can cut it off, which encourages continuous branching. Also be sure to check the pot regularly, promptly cut off diseased and yellow leaves, and spray with carbendazim or chlorothalonil on a regular basis.

Propagating curly-leaf mint is also very simple. Just cut a few stem sections about 7-9 cm long, then remove all the leaves from the bottom of the stems and soak the bottom 2-3 cm directly in clean water. After that, change the water once every 2 days, and it will root in less than a week.

Curly-leaf mint does not need much light to grow and can also grow in shade, but if you want it to grow faster, it is best to give it a little scattered light each day, which promotes faster growth.

Keep the growing environment ventilated, warm and humid, and avoid excessively dry air.

Curly-leaf mint is not too sensitive to ambient temperature. Its growing temperature is between 15-30°C; just keep the year-round care temperature above 15°C and the maximum temperature below 30°C. Its adaptability to the environment is quite good.

Keeping a few pots of curly-leaf mint at home is also quite nice. It can purify most harmful gases and also has a certain sterilizing effect. Moreover, curly-leaf mint is completely non-toxic and harmless, and properly grown leaves can even be eaten, so there is no need to worry about poisoning from accidental ingestion.

Differences between curly-leaf mint and round-leaf pilea:

The plant in the picture above is curly-leaf mint. People at flower markets and flower shops call it "air-purifying grass." It has a certain ability to purify the air and is a small herbaceous plant that even beginners can easily keep alive. It is suitable as an indoor potted plant; it is shade-tolerant and drought-tolerant, and if you want it to grow lushly, you only need to keep pruning it.

The plant in the picture above is round-leaf pilea. You can see that its leaf shape looks quite similar to curly-leaf mint, and the leaves also have wavy, wrinkled edges, with similar veins. However, the leaf surface of round-leaf pilea has raised prickles, while curly-leaf mint does not.

That is all for the introduction to curly-leaf mint. Now you can clearly understand the differences between curly-leaf mint and round-leaf pilea!

I.Grow different flowers at home according to different growing environments
1. Entrance hall
The entrance hall is the entryway of the home, 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 simple, all of which can be felt from the decoration of the entrance hall.
The entrance hall space in a home is often relatively narrow, and sometimes it is just a corridor passageway. It is the necessary passage to the living room, and most of it is relatively dim. For greenery 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, hung in hanging form, which can save space and enliven the atmosphere. In short, the plants chosen for greenery decoration here are preferably those with fine leaf shapes and soft stems and branches, to soften the visual line of 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 key point of greenery decoration in the entire home. To some extent, the degree of decoration in the living room can show the owner's identity, status and interests. The greenery decoration of the living room should reflect a hospitable and happy atmosphere. Plant arrangement should highlight the key points and avoid clutter. It should strive to be beautiful, generous and dignified, while also paying attention to harmony with the style of the furniture and the color of the walls. If a luxurious and imposing look is required, plants with larger leaves and taller forms can be chosen, such as Maraba chestnut, Brazilian iron and green giant as the main plants, or vines such as areca palm, weeping fig, golden pothos and emerald gem as the main scene; if an elegant and antique look 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, delicate foliage plants must be placed on the coffee table, flower stand, windowsill or table near the sofa, such as ornamental bromeliads, peacock arrowroot and Alocasia. If necessary, fresh flowers or seasonal flowers can also be placed on the table. This combination not only highlights the theme of the living room layout, but also keeps the room evergreen and full of vitality throughout the four seasons.
3. Study
The study is a place for reading, writing, and sometimes also for receiving guests. The greenery decoration of the study should be bright, fresh and elegant, thus creating a quiet, peaceful and graceful 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; instead, choose plants with non-dazzling colors and relatively ordinary forms, reflecting a restrained style. Generally, a pot of light and elegant asparagus fern or green plants such as net-veined grass or Syngonium can be placed on the desk to adjust eyesight and relieve fatigue; hanging plants with spreading, drooping forms can be chosen, such as golden pothos, heartleaf philodendron, ivy and inch plant, hung at the corner of the wall or trailing down from the top of a bookcase; a climbing plant can also be placed in a suitable position, such as fiddle-leaf philodendron, golden pothos and heartleaf philodendron, like a coiled dragon soaring into the air, giving people the passion to strive upward.
4. Bedroom
The main function of the bedroom is sleep and rest. A person spends about 1/3 of their life 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 seems crowded, it is better to choose small, light-green plants. Matching bonsai should also not have bright colors or peculiar shapes. Asparagus fern, monstera and ferns can be placed on the desk or flower stand. If space permits, plants with neat forms can also be placed on the floor, such as heartleaf philodendron, Brazilian iron and umbrella tree. 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 eat or gather. When decorating, the theme should be sweetness and cleanliness, and indoor foliage plants with bright colors can be appropriately placed. At the same time, fully consider saving space and focus on three-dimensional decoration. In principle, the selected plants should be small in form. For example, on a multi-tiered flower stand, display several small, delicate, green indoor foliage plants (such as ornamental bromeliads, peperomia, monstera, lily grass, peacock arrowroot, asparagus fern and pilea). A clearly shaped indoor foliage plant such as golden pothos, Maraba chestnut or Dutch iron can also be placed in the corner. This can lift people's spirits and increase appetite.

II.Grow different flowers at home 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 bringing in wealth.
2. Kumquat
Growing kumquat at home carries the meaning of gold and silver treasures and is quite helpful for increasing financial resources. But note: do not pull the kumquats 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 luck and wishes, and also attract wealth. Keep in mind: before narcissus blooms, it looks just like a large scallion, and it is very important to keep it fresh.
4. Chrysanthemum
Growing chrysanthemums at home symbolizes prolonging life and increasing blessings, and helps with the feng shui keywords of indoor decoration related to qi field and magnetic field. But note: longevity chrysanthemum and cosmos are both suitable for placing at home, but pay attention to sunlight and also watch for pests. In addition, sterilizing substances secreted by flowers such as jasmine, clove, honeysuckle and morning glory grown at home can kill certain bacteria in the air, inhibit diphtheria, tuberculosis and dysentery pathogens and typhoid bacteria, and keep indoor air clean and hygienic.

III.Grow different flowers at home according to different floral functions
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; it is best not to place flowers and plants in the bedroom. If they must be placed, some small and delicate succulents such as cactus and cactus ball can be chosen as accents.
Aloe, spider plant and snake plant can remove formaldehyde. In a 15 sq m room, planting two pots of snake plant or spider plant can keep the air fresh and free from formaldehyde harm. Snake plant can also release a large amount of oxygen during the day. Spider plant can also release sterilizing 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 fragrant flowers such as rose, osmanthus, violet, jasmine, lemon, rose, dianthus, lily of the valley and crape myrtle have significant sterilizing effects.
Plants such as crape myrtle, jasmine and lemon can kill diphtheria bacteria, dysentery bacteria and other native bacteria within 5 minutes. The fragrances released by plants such as rose, dianthus, lily of the valley, violet, rose and osmanthus have obvious inhibitory effects on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus and Staphylococcus.
Succulents 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, bowstring hemp, 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 relax people, make them 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, pay attention to: 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 and ivy.
2. Fragrance 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 for people with neurasthenia, but it should not be too strong, otherwise it can also cause dizziness.
White orchid fragrance: can sterilize and purify the air.
3. Plants that can absorb toxic chemical substances
Aloe, spider plant, snake plant, Aspidistra and monstera 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 extremely strong. Aloe is also good at absorbing formaldehyde and can absorb 90% of the formaldehyde contained in 1 cubic meter of air. Ivy, cycad, chrysanthemum, kumquat, pomegranate, purslane, Chinese rose, camellia, pomegranate, Aglaia, 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 and Excoecaria 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 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 (ball) can resist radiation
Cactus and succulents have a nickname - "lazy person's plants." This type of plant requires little care and attention, and hydroponic cactus ball is even easier to maintain. Because cactus (ball) grows in places with strong sunlight, its ability to resist ultraviolet and other radiation is especially strong. Hydroponic cactus ball is clean, environmentally friendly and odorless. If you place one or two pots of hydroponic cactus (ball) beside your computer, it can help the human body absorb as little radiation released by the computer as possible. Because cactus (ball) grows in places with strong sunlight, its ability to absorb radiation is especially strong.
(2) Cactus ball, known as a nighttime "oxygen bar"
Cactus ball mostly respires at night when it is cooler and more humid. During respiration, it inhales carbon dioxide and releases oxygen. Therefore, placing such a large plant as golden barrel cactus indoors is tantamount to adding an air freshener and can purify indoor air. Thus it is also an ideal flower for indoor placement at night.
(3) A master at adsorbing dust. Do not underestimate cactus ball; it is also a master at adsorbing 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) Ivy, Chinese rose, rose, aloe and evergreen can effectively remove indoor trichloroethylene, hydrogen sulfide, benzene, phenol, hydrogen fluoride and ether.
(3) Eucalyptus, asparagus fern, Euphorbia and cactus can kill bacteria; asparagus fern can also remove heavy metal particles.
(4) Ivy, fig, Swiss cheese plant and ordinary aloe can not only deal with bacteria and other harmful substances brought in from outdoors, but can even absorb dust that is difficult for vacuum cleaners to pick up.
(5) Monstera, 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 pot plants should be mainly used. It is suitable to place a pot of light-colored fragrant plants such as jasmine, osmanthus, Chinese rose or banana shrub, or to place plants with small leaves such as asparagus fern and zebra plant. Flowers that are too gaudy make it hard for people to fall asleep and are not suitable for placement. Bedroom flower types are generally smaller, 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 emphasis should be quietness. In greenery and beautification arrangement, it should be conducive 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 a reading environment that is both artistic and elegant.
3. Living room
First of all, focus on decorative beauty. The number should not be too large, 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 bird's nest fern can be placed beside the sofa or in unused space; in a small living room, small plants or trailing plants can be chosen, such as ivy and spiderwort. In addition, they should be placed against the wall corner so as not to hinder people's movement. The living room is generally mainly decorated with bonsai. Some small, bright potted flowers, plum blossoms or plant bonsai can be placed on the coffee table. In the room, the contrast of sizes and flowers and leaves sets off the lively vitality of the living room.
4. Dining room
Greenery decorations that make people feel happy and can increase appetite should be chosen. For example, begonia and poinsettia can add a cheerful atmosphere, and medium-sized potted plants placed on the serving table have a spacing effect. Bright green potted plants can all be placed around the dining room. In the center of the dining room, spring orchids, autumn chrysanthemums, summer perilla and winter 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
It is usually located in a north-facing room with fewer windows, and some potted plants can be used for decoration to 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 that are temporarily not being eaten 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 and have poor lighting conditions. Plants with less strict light requirements should be chosen, such as pitcher plant, pilea and small ferns.
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 and kumquat), and foliage potted plants can be placed against the wall, setting each other off. Two pots of flowers (such as Chinese rose and autumn crocus) can also be placed on the balcony window, which not only increases the overall beauty but also 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 you to pick the freshest aloe leaves at any time for home health care. Some people say that growing a few pots of aloe at home is like hiring 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 flowering period of aloe is short, the flower colors are also very brilliant and very popular. Small potted aloe can be placed on a desk, and large plants can be potted and placed in the courtyard, paired with other succulents to form a unique natural landscape full of interest. In winter, it can be moved to 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 and purify indoor air.
Aloe can effectively remove formaldehyde from the air. Planting a few aloe plants is like installing several "biological air fresheners" in the home, purifying the living environment all the time. When harmful gases in the air, such as carbon monoxide, carbon dioxide, sulfur dioxide and formaldehyde, remain at a relatively high level for a long time and aloe can no longer completely remove and absorb them, spots will appear on the leaves, warning you to quickly take corresponding measures to avoid harm to human health from harmful gases.
2. Spider plant
Its place of origin is South Africa, and it belongs to the Liliaceae family. It is highly adaptable, relatively drought-tolerant and cold-tolerant, prefers warmth and humidity, and is suited to growing in loose, fertile, well-drained soil. Spider plant is one of the most traditional hanging houseplants. Its leaves are slender and soft, and the trailing stems growing from the leaf axils bear small plantlets that hang down from the rim of the pot, spreading and draping gracefully like flowers, evergreen all year round; it is both sturdy and gentle, shaped like a crane spreading its wings to leap, hence the ancient name "crane-fold orchid."
It also has the alternative names of Chuipencao, Guilan, and Goulan, and in Western Europe it is also called spider grass or airplane grass. Spider plant is not only an excellent hanging foliage plant for indoors, but also a good indoor air-purifying flowering plant. Spider plant has a very strong ability to absorb toxic gases, and can purify toxic gases such as carbon monoxide, carbon dioxide, and formaldehyde. Generally, keeping 1 to 2 pots of spider plant in a room can absorb nearly all the toxic gases in the air, so spider plant also has the fine name of "green purifier."
Growing flowers and plants indoors can "create" a good microclimate. In modern buildings constructed with reinforced concrete precast slabs, the indoor air humidity is much lower than normal standards, almost the same as in a desert. But a plant called Cyperus rotundus can turn a "desert" into an "oasis." Cyperus rotundus likes water, so potted Cyperus rotundus 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 plant, and the like 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 insufficient indoor oxygen, but an extreme shortage of negative oxygen ions. When a television or computer is running indoors, negative oxygen ions decrease rapidly. There are many flowers and plants that can be grown indoors that can produce negative oxygen ions - these flowers and plants are Cupressus funebris, Platycladus orientalis, and Cryptomeria japonica.
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, it is popular in the West to grow spruce and other low-growing conifers on balconies; they can fill the room with a refreshing tree fragrance.
Placing some pollution-resistant flowers and plants in the home can also play the role of an air purifier. For example: English ivy can "eat" benzene, spider plant can "devour" indoor carbon monoxide and formaldehyde, and the spathe of Arisaema can absorb benzene and trichloroethylene. If there is one pollution-resistant plant in a 10 sq m room, it will greatly help air purification.

Six.Flowers that are not suitable for growing at home
Unsuitable flowers: lilac and night-blooming cestrum 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 too much contact can easily cause hair loss; the oily fragrance released by pine and cypress plants can affect people's appetite. Do not grow "mutually incompatible" flowers: if rose and mignonette are placed 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, causing the plants to die.
Do not keep flowers in a sick person's room. The fungal spores produced by the soil in flowerpots will spread into the indoor air, causing surface 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 is like adding frost to snow, 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, answered these doubts. He believes that concern about "Alocasia macrorrhizos" 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 deliciosa is a natural scavenger and can remove harmful substances from the air, but it is also a toxic flower.
Golden pothos is evergreen all year round and can absorb toxic gases, but the sap of golden pothos is toxic; contact with the skin can cause redness and itching, and accidental ingestion can also cause throat pain; Rohdea japonica belongs to the Liliaceae family, and its toxic part is the rhizome; accidental ingestion of a large amount of the rhizome can cause symptoms such as nausea, abdominal pain, cold limbs, and even coma. As for Dieffenbachia seguine, the sap of the leaves can make a person mute. Professor Guo Xichang of the Department of Forestry at Shenyang Agricultural University believes that plants in the Euphorbiaceae and Thymelaeaceae families are also toxic, such as Euphorbia milii, one of the 52 cancer-promoting plants, and it is better not to grow them at home. However, for toxic flowers such as Alocasia macrorrhizos and golden pothos that can purify household air, there is absolutely no need to smash them.

Seven.Precautions for growing flowers at home
Experts believe that the proper attitude toward toxic plants is: keep an appropriate distance, do not casually play with or stroke them; do not hold the branches, leaves, or fruits in the mouth. Experts also summarized 10 kinds of flowers that should be avoided as much as possible in the bedroom: for example, the fragrance of orchid can cause insomnia; mimosa may cause hair loss; the pollen of redbud can trigger asthma and worsen coughing; night-blooming cestrum can cause dizziness; the fragrance of lily can cause insomnia; the fragrance of Chinese rose can make people depressed; the milky white liquid secreted by oleander can cause poisoning; the fragrance of pine and cypress can make people lose appetite; hydrangea can easily cause allergies; tulip flowers can cause hair loss. Regarding 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 sq m, it is only suitable to place 2 medium or large plants, while 3 or 4 small plants can be placed.
