Detailed guide to separating and transplanting African violet seedlings, sharing flower-growing techniques
Generally, African violet leaf-cutting seedlings can be separated once they have 4-6 leaves. Seedling separation should avoid hot, humid weather and cold, overcast weather, otherwise the seedlings easily rot.
Wait until the medium is somewhat drier before separating. Take the leaf with seedlings out of the pot, shake off the loose medium, and carefully pull the seedlings off with your hands.
Prepare the medium for the seedlings in advance so it is loose with a certain degree of moisture; it should be suitable when a handful does not clump together. Put the medium into a small flower pot and dig a hole in the middle, place the seedling in, gently press the medium firm with your fingers, fix the seedling's position, and bury it to a depth that just exposes the growth point. Newly separated and planted seedlings should not be watered immediately. Water the seedlings one day after planting. After one week in a place with bright indirect light and good ventilation, move them into normal care. Some violet enthusiasts suggest that after separation the seedlings should be placed in a plastic box to maintain humidity, especially in dry northern climates where humidity retention is very important. Once the seedling roots have grown well and the plants begin to grow, they can enter normal care; this process takes about two weeks or longer.
Not every seedling is the same size. Separate the larger seedlings and leave the smaller ones still attached to the mother leaf. Sometimes the small buds at the growth point have not yet developed into seedlings, so you can put the mother leaf back into the original pot, bury it well, and wait for it to continue growing seedlings. These can all become seedlings in the future, but the later seedlings are often not as robust as those that grew earlier. Of course, if you do not plan to propagate more, it is better to throw them away. The mother leaf that has just been separated should also not be watered immediately; this is mainly to prevent the wounds from separation from becoming infected.
The complete process of African violet seed propagation: African violet growing methods
Flower Bonsai Network introduction: Today Flower Bonsai Network shares with you an article on the complete process of African violet seed propagation and African violet growing methods. Let's take a look.
African violets are commonly used in the home to beautify rooms, and African violets are also a relatively easy species to keep alive. Below is an introduction to the process of propagating African violets from seed.
Preparation before sowing African violets:
Sowing season: spring and autumn are more suitable, at 20-25 degrees.
1. Container: a relatively small plastic box can be used, such as a single mooncake packaging box or a translucent fast-food container.
2. Medium: unused small-grained vermiculite can be used.
3. Prepare cling film for sealing the container.
Operating steps when sowing African violets
Seed soaking:
Put the seeds in a paper packet and soak them in room-temperature water (about 20-25°C) for 8-12 hours. Do not open the paper packet while soaking; directly soak the paper packet in water, then squeeze the paper packet to expel air so the seeds are thoroughly soaked.
The sowing container does not need drainage holes. Wet the medium in the sowing container thoroughly with tap water or purified water.
Sowing method:
Use a paper towel to blot away the water from the soaked seed paper packet. Open the packet and use a toothpick to move the seeds into the sowing container. Finish sowing before the paper packet is completely dry. After sowing, do not cover with soil or water. The distance between seeds should preferably be more than one centimeter.
Maintenance after sowing African violets (temperature, humidity, light)
After sowing, seal the sowing box with cling film, then place it in a larger, light-transmitting container with a lid or that can be sealed. Water can be added inside the container to maintain humidity, and the container should be placed in a place without direct sunlight. At an ambient temperature of 20-25, seeds generally begin to germinate in 10-20 days.
African violet sprouting, seedling separation, and transplanting
1. After germination, the seedlings need humidity retention. After most seedlings have produced 2 leaves, gradually open the cling film seal of the sowing box for ventilation until it is completely open, but the sowing box still needs to be placed inside the larger container.
2. The seedlings are very delicate and can only be placed in a place without direct sunlight.
3. When there are too many seedlings in the sowing box, promptly use a toothpick to separate the seedlings in densely sprouted areas.
4. After the seedlings are larger, apply diluted fertilizer to promote growth.
5. After the seedlings grow 4-6 leaves, you can consider using a 2-in-1 or 3-in-1 medium to separate and temporarily plant them at the appropriate time.
African violet growing methods
Not long ago I had the idea to write about African violet growing methods, but I kept delaying because I felt it was not mature or certain enough. Below I will briefly talk about my journey of growing African violets, for flower friends' reference.
I. Growing section
1. In the early years, I intermittently kept some Binfen African violets. The most memorable time was when I foolishly went alone to Fangcun in Guangzhou and bought nine African violets back, then desperately followed books to propagate by leaf cuttings, and surprisingly succeeded. At the time, two words: excited. In the Spring Festival flower market in 2007, I bought another box of Binfen African violets. At that time Binfen varieties were truly abundant, and I continued to propagate like crazy. Then one summer, most of them died, leaving only a few large seedlings.
2. By chance I joined a local flower friends group. After joining, I found that the African violets I had were really somewhat embarrassing to show. The big collectors and experts and the varieties made me gasp in amazement, so I actively participated in group activities and did not miss any chance to grab leaves or seedlings. After a year of effort, the varieties I had became much richer, and I also gained recognition from the big collectors. Although I borrowed many methods and precautions, many still died in summer.
3. After some more time, something strange happened: the local big collectors all gave up growing African violets and said they were willing to pass theirs to me. At the time I really did not dare take them all at once, because I truly was not confident I could let them settle in my home. I only took a small portion. After a summer, I found that the African violets in my hands were still fine, so only then did I dare take over the African violets from the big collectors around me. So I suddenly became one of the few local big collectors of African violets.
4. The trust and support of flower friends made me put more care into growing African violets. I kept thinking about how to let them spend summer safely in my home without an air-conditioning budget, and I thought of this saying: a starved camel is still bigger than a horse! With greater numbers, there are always some that survive. So I threw myself into leaf cuttings and propagation, busy and happy. After that summer, something strange happened again: most of these densely leaf-propagated seedlings actually spent summer safely on the balcony, only some older mother plants and some variegated varieties died. In this process I found that on the issue of getting through summer, seedlings have stronger resistance than old plants, group living works better than living alone, and new soil is better than old soil. Because of this small success, the number of African violets suddenly went up.
5. With the previous year's experience, one month before summer in the second year, I beheaded all the large seedlings and replanted them with new growing medium, and continued leaf-cutting backups for certain varieties. Because there were really quite a lot of medium and small seedlings at home, beheading and grouping them all would be too much work, so I changed the method and stacked them on a plate with perlite as the base, letting their roots extend from the bottom of the pots into the perlite layer, creating a virtual group-living environment to connect with the ground. That year not many died, but later I found that seedlings in the later part of summer generally suffered from root mealybugs, so there was another round of beheading and replanting. Tiring! This method is still relatively advisable for those with not many plants.
6. Leaf-cutting propagation: using a larger shallow basin for orderly dense planting works better than separate leaf cuttings in small pots. I guess African violets are also afraid of loneliness and deeply understand that unity is strength. Leaf-cutting is better when the temperature can remain at 15-30°C for a relatively long time, especially in the early stage of leaf cutting. If air humidity is low during leaf cutting, cover with film to maintain humidity, and the humidity-retention space should not be too small.
7. Watering: water early in spring; water at noon in winter; in summer, if you cannot guarantee getting up early enough, watering in the evening is better; in autumn, supplement water more. African violets are relatively moisture-tolerant plants, so try to keep the soil moist. It is best to water heavily once a month to dilute accumulated salts in the pot. Everything has a limit: too wet easily breeds bacteria, too dry easily attracts pests.
8. Fertilizing: apply more during the growing period, do not apply when too cold or too hot, apply less during the flowering period, and apply diluted fertilizer frequently.
9. Sterilization: what cannot be seen with the naked eye is often the most destructive. By the time bacterial infection in plants is discovered, it is generally already too late. During plum rain weather, increase the frequency of sterilization. For African violets splashed by rainwater, use a method of rinsing once with water to achieve a cleaning effect.
10. Pests: it is hard to grow flowers without dealing with pests. Prevention is better than treatment, especially preventing root mealybugs in high summer temperatures and mite damage in dry autumn and winter. If root mealybugs occur in home or office cultivation, it is recommended to behead and replant with new soil (do not use pesticides unless necessary). When beheading, note that the stem should not be left too long and the leaves should not be left too many. Remove the flower stalks and flower buds and keep only the top three layers of leaves. The stem only needs to be kept 0.5 cm long. If conditions allow, it is best to place it in a transparent humidity box (that is, a transparent storage box), observe the seedling condition, and after half a month normal care can resume.
11. Soil: it is recommended to use imported peat soil with relatively fine fibers. Domestic soil is really relatively poor. Right next to me there is a place making humus soil, with a frightening formula. For the ratio of peat soil to perlite, one to one is basically universal. Too much perlite and too little peat will result in fewer nutrients, and seedlings will grow relatively weakly.
12. Changing soil: it is best to do it one to one and a half months before summer. It is recommended to do it again at Mid-Autumn Festival. It is best to ensure changing soil once a year to increase the nutrients needed for plant growth.
13. Light: light is a necessary factor for plant growth. Generally speaking, sufficient bright indirect light allows African violets to grow normally. The main factor affecting flowering is light. Direct sunlight before nine in the morning is nutrient-rich and generally does not burn leaves. Plants will naturally come into flower once they grow to a certain stage, so do not rush to see flowers, and the light conditions in the early flowering stage have an obvious effect on the later flowering quality. This autumn I found that autumn sunlight is very harsh, possibly related to low air humidity. What does not get sunburned in summer becomes severely sunburned in autumn. This point requires special attention!!
14. Flower pots: generally plastic pots are sufficient. Determine pot size according to plant size; too large or too small is not good. If you want earlier flowering, you can appropriately use a smaller pot for planting. If you want overall beauty, you can put a suitable ceramic pot outside the plastic pot. Red clay pots have good breathability but watering must keep up, and they easily accumulate salt, so after a long time it is best to soak and wash them thoroughly several times before reuse.
II. Experience section
1. Create a good small growing environment, and the path of growing African violets will be smooth like a fish in water. For example, adding some medium to large green plants around the African violets both blocks light and increases humidity, and can also ease the loneliness of the African violets.
2. Other people's methods are always only reference answers; combine them with your own actual situation (time, space, varieties).
3. Observe carefully, summarize, compare, practice, and communicate; flower-growing skills improve quickly.
4. Learn from nature, understand the plant's native ecological environment, and simulate and recreate the native growing environment.
III. Choosing seedlings
1. Be sure to choose varieties you truly like. Only what you truly like will you care about, and only then will you put thought into growing it well.
2. When choosing seedlings in physical stores, choose strong ones with spreading, emerald-green leaves. When buying from Taobao stores, do not rush; it is best to first ask the store about the seedling condition. Seedlings are not better the larger they are, but of course they should not be too small either. 8-12 true leaves is about right. Seedlings that are too large or too old are easily damaged during packaging, and accidents are also likely during the acclimatization process. Large and old seedlings do not have as good vitality as small seedlings, so it is not recommended to pursue large seedlings or flowering plants. Think about how many hours our children at home can cry and you will know how strong vitality is; we cannot cry for half an hour.
IV. Acclimatization
1. When dividing leaf-cutting seedlings, remove the old small leaves, plant them in prepared new moist soil, press lightly firm, and maintain appropriate humidity. During this period, pay attention to replenishing water and keep the soil normally moist. Generally, normal care can begin after half a month.
2. For seedlings bought online (non-chimera varieties), regardless of the seedling condition, it is recommended to first remove a few leaves for cutting propagation to guard against any mishap during acclimatization. Tidy and clean up the root ball, similarly plant in prepared new moist soil with light firming, use a relatively large space with appropriate humidity, pay attention to replenishing water during this period, and keep the soil normally moist. Generally, normal care can begin after half a month. 3. Fertilizing is not recommended during acclimatization (a weak body cannot absorb tonics); haste makes waste!
V. Flowering
1. When the appropriate temperature conditions and maturity are reached, African violets will naturally produce flower buds. Do not rush. When flowers bloom and can be picked, pick them; do not wait until there are no flowers and break off empty branches.
2. When the seedling is mature and environmental conditions are mature, you can appropriately increase the frequency of flowering-promoting fertilizer, but also remember not to be impatient or use too strong a concentration.
3. Before flowering, generally more side shoots appear (some say suckers). These shoots are either side shoots or will really become large side shoots. The appearance of these shoots more or less affects flowering quality. Unless it is for propagation, they can be removed so the plant grows symmetrically and beautifully.
4. When temperature and humidity are not ideal, broken flowers often appear. This is also normal. Do not doubt your technique or think the variety is wrong. African violets are changeable; it does not mean they are always beautiful, they also have an ugly side, and we must learn to accept it. These flowers that bloom under abnormal conditions at normal times can be removed; when growth conditions are not ideal, strange flowers will also appear.
5. From seeing a flower bud to the flower opening, African violets take a very, very long time. You must be patient. In my memory it takes about a month. You must learn to enjoy this process of anticipation. If you want flowering to speed up, I think a good method is to grow several plants and several varieties, so the time is spread out, and some may bloom unexpectedly without you even knowing.
6. If you want overall elegance, you still need to handle the African violets manually. Those grown with light from one side must be rotated 180 degrees from time to time. Generally, adjusting once every two [periods] is enough. Also, when flower buds are squeezed under the leaves and cannot rise above them, you can gently help support them by hand. This way the flowers will be more concentrated; with a few more, there will be a flower ball, and it will not be too messy.
I said I would write it well, but as I wrote it seems to have become messy again. Everyone please make do with reading it! It will be updated, revised, and improved from time to time. I hope it helps everyone grow African violets. If you succeed, count me in for part of the credit; if you fail, do not give up easily! Finally, I send a few especially beloved African violets to encourage us together

Ageratum growing methods and precautions: introduction to Ageratum
Ageratum is native to tropical America. It is a perennial herb, often cultivated as an annual, 30-60 cm tall, with the whole plant covered in hair.
The stems are spreading, rooting at the nodes, covered with white soft hairs. Leaves are opposite, leaf blades ovate. The flower heads are capitula; all the florets are tubular, and flower colors include light blue, blue, pink, white, etc. The flowering period is from July to frost.
The achenes are 1.5-1.8 mm long and easily fall off. The thousand-seed weight is 0.15 grams. It likes a warm, sunny environment.
It has no strict requirements for soil. It is not cold-tolerant and grows poorly under intense heat. It has strong branching ability and tolerates pruning. Propagate by seed; excellent varieties can be propagated by cuttings. Used for flowerbed and flower-border arrangements, potted ornamental display, and as cut flowers.
Ageratum is distributed in Guangdong, Guangxi, Yunnan, Guizhou, Sichuan, Jiangxi, Fujian and other places in China. It is cultivated, and there are also naturalized wild distributions. It grows in valleys, under forests or at forest edges on mountain slopes, by rivers or on mountain slope grasslands, at field edges, or on wasteland. In Zhejiang and Hebei it is only seen in cultivation.
Morphological characteristics of Ageratum
Ageratum is an annual herb, 50-100 cm tall, sometimes less than 10 cm, with sparse short soft hairs and yellow glandular dots, with slightly more hairs along the veins on the upper side and on the underside of the leaves, sometimes nearly hairless underneath. The petioles of the upper leaves or the axillary young branches and the petioles of the small leaves on axillary branches are usually covered with dense, spreading white long soft hairs. The capitula, 4-18 of them, are arranged at the top of the stem in usually dense corymbose inflorescences; the inflorescence diameter is 1.5-3 cm, rarely arranged in loose corymbose form.
The pedicels are 0.5-1.5 cm long and covered with dusty short soft hairs. The involucre is bell-shaped or hemispherical, 5 mm wide. The involucral bracts are in 2 layers, oblong or lanceolate-oblong, 3-4 mm long, hairless outside, with torn edges. The corolla is 1.5-2.5 mm long, hairless outside or with dusty fine soft hairs at the tip, the limb 5-lobed, light purple. The achene is blackish brown, 5-ribbed, 1.2-1.7 mm long, with sparse white fine soft hairs. The pappus scales are 5 or 6, oblong, with the apex abruptly narrowed or gradually narrowed into a long or short awn, or some scales truncate at the apex without an awn-like tapering point; all pappus scales are 1.5-3 mm long.
Ageratum has no obvious main root. The stem is stout, 4 mm in diameter at the base, or rarely slender with a basal diameter of less than 1 mm, unbranched or branched from the base or from above the middle, or the lower base prostrate with nodes often producing adventitious roots. All stems and branches are light red, or the upper part green, covered with white dusty short soft hairs or the upper part covered with dense spreading long tomentum. Leaves are opposite, sometimes alternate above, often with axillary undeveloped leaf buds. The middle stem leaves are ovate or elliptical or oblong, 3-8 cm long, 2-5 cm wide; from the middle leaves upward and downward and the leaves on axillary branchlets gradually become smaller or small, ovate or oblong, sometimes all leaves of the plant are small, only 1 cm long and only up to 0.6 mm wide. All leaves are obtuse or broadly cuneate at the base, with three basal veins or indistinct five-veined, acute at the apex, with rounded serrations at the margin, with petioles 1-3 cm long, both surfaces covered with white.
Ecological habits of Ageratum
Ageratum grows in valleys, under forests or at forest edges on mountain slopes, by rivers or on mountain slope grasslands, at field edges, or on wasteland. In Zhejiang and Hebei it is only seen in cultivation.
Ageratum likes a warm, sunny environment. It has no strict requirements for soil. It is not cold-tolerant and grows poorly under intense heat. It has strong branching ability and tolerates pruning.
Ageratum cultivation techniques: raising seedlings
Ageratum seeds are tiny, and sowing requires meticulous work. Generally, sow in a greenhouse in early February, or sow outdoors in early April. The growing soil should be half farm manure and half garden soil, mixed with a small amount of leaf mold, mixed evenly and then sifted. For raising a small number of seedlings, flower pots can be used (for large-scale seedling raising, beds can be made). Put the growing soil into the pot, press firm, and water thoroughly. After the water seeps down, evenly scatter the seeds on the wet soil. Do not cover with too much soil; just enough to cover the seeds tightly. Keep the pot soil moist. Seedlings can emerge in about 10 days. When the seedlings have 2 pairs of true leaves, separate them, using small plastic nutrient pots, planting 1 plant per pot. The seedlings grow slowly.
To achieve early shaping and early flowering, cutting propagation can be used. For cutting propagation, prepare large mother plants, place them in a greenhouse in winter, and in early spring take healthy branches, retaining 2-4 true leaves and not keeping the growth point. The branch length is 5-6 cm, and the cut should be below a node. Insert immediately after cutting. The insertion depth is 1/3-1/2 of the cutting length. In high-temperature seasons, place them in a cool place after cutting to prevent high temperature and sun exposure. Apart from low temperatures in winter, cutting propagation can be carried out in other growing seasons and roots easily.
Planting out
When Ageratum seedlings produce 2-4 branches, plant them out into pots. Plant 1 plant in a 4-inch flower pot. The pot soil should be 1/3 farm manure, 1/3 garden soil, and 1/3 fine sand, mixed and sifted. After planting the seedlings, the pot soil should be pressed firm, watered thoroughly, and placed in a cool place. After 7-10 days, move to a sunny place. At this time they have basically acclimatized and begin normal growth. Pay attention to water and fertilizer management. Water when the surface layer of the pot soil turns white and looks dry. Each watering should be sufficient; do not water only halfway. Entering the high-temperature season, the plant's peak growing period, water twice a day. Apply diluted cake fertilizer water once every 10-15 days, and appropriately increase phosphorus and potassium fertilizer. This can dwarf the plant, produce more flowers with brighter colors, and improve ornamental value.
Pruning
Ageratum has a long flowering period. To maintain a short, compact plant shape with many beautiful flowers, multiple pinching is necessary, generally pinching the tips 3-4 times. To form a rounded plant shape, the tops of all branches should be able to form flower buds and bloom at the same time, making the branches and leaves lush, with many bright flowers, beautiful and spectacular. After the first batch of flowers finishes, promptly prune and trim. Generally keep old branches 5-6 cm high and cut off the upper part, while thinning out overly dense branches. Then ensure sufficient water and fertilizer to promote the sprouting of new branches, so that the leaves are green and the flowers fresh.
Seed collection
Ageratum seeds easily fall off after maturing, so they should be collected in time. When most of the small florets in the capitulum have dried up and the achene pappus is clearly exposed, they can be collected. After drying, the seeds can be rubbed off, cleaned, put into a cloth bag, and stored in a cool, dry place. Ageratum has a long flowering period, and seed maturity is not concentrated, so multiple collections should be made. The leaves are large and produce a lot of starch through photosynthesis, making it a good material for photosynthesis experiments.
Temperature environment
Ageratum has a relatively strong adaptability to light. When keeping it indoors, place it as much as possible in a place with bright light, such as a well-lit living room, bedroom, study, and similar places. It likes a moist or semi-dry growing environment, and requires the relative air temperature of the growing environment to be 50-70%. When the relative air humidity is too low, the lower leaves yellow and fall off, and the upper leaves lose gloss. Ageratum is not cold-tolerant. Before frost arrives, move it indoors and place it in a sunny place. The nighttime temperature should be above 5°C, and it can grow and bloom normally at a daytime temperature of 10°C-15°C. Water once every 3-5 days, and apply diluted cake fertilizer water once every half month. After keeping it indoors for a period, move it outdoors to a shaded place (with insulation conditions in winter) for a period of care, and alternate in this way.
Humidity management
It likes a moist or semi-dry climate environment and requires the relative air temperature of the growing environment to be 50-70%. When the relative air humidity is too low, the lower leaves yellow and fall off, and the upper leaves lose gloss.
Temperature management
Because it is native to subtropical regions, it has very strict requirements for winter temperature. When the environmental temperature is below 8°C, growth stops.
Light management
It has a relatively strong adaptability to light. When keeping it indoors, place it as much as possible in a place with bright light, such as a well-lit living room, bedroom, study, and similar places. After keeping it indoors for a period (about one month), move it outdoors to a shaded place (with insulation conditions in winter) for a period of care (about one month), and alternate in this way.

The nighttime temperature should be above 5°C, and it can grow and bloom normally at a daytime temperature of 10°C-15°C. Water once every 3-5 days, and apply diluted cake fertilizer water once every half month.
Ageratum propagation methods
Ageratum likes a warm, sunny environment. It has no strict requirements for soil. It is not cold-tolerant and grows poorly under intense heat. It has strong branching ability and tolerates pruning. Propagate by seed; excellent varieties can be propagated by cuttings.
It is often propagated by sowing and cutting. For sowing, sow in spring in April. It germinates 2 weeks after sowing. For cutting, from May to June cut the top tender branches as cuttings; they root in about 15 days after insertion, with a high survival rate. The seeds have the ability to self-sow and reproduce.
Sown seedlings are transplanted once when 3-4 cm tall, and planted out or potted when 7-8 cm tall. During the growing period, fertilize once every half month. Pinch when there are 6-7 leaves to promote more branching. During the flowering period, increase phosphorus fertilizer 1-2 times. After the flowers fade, prune heavily once, and after new branches sprout they will continue to bloom continuously.
For Ageratum seed propagation, raise seedlings in indoor hotbeds from March to April in early spring, and plant out in the open field in mid-April. For some excellent varieties, cutting propagation can be used, or tissue culture can be applied for rapid seedling raising. Ageratum has strong adaptability and is not choosy about soil; it can grow well in sandy loam, garden soil, and slightly acidic or slightly alkaline soil. Under sufficient sunlight, the flowers are dense and the colors are bright; in shaded environments, the stems and leaves are bright green and the ground-covering effect is good. Ageratum tolerates pruning and can be pruned at any time after flowering to form new flowers. During the growing period, an appropriate amount of topdressing is required. Compound chemical fertilizer or dried chicken manure can be used. Remember to irrigate immediately after fertilizing, otherwise it easily burns the leaf surface or the plant roots.
In early spring, Ageratum can produce seedlings with about 9 pairs of leaves and many large buds in about 60 days. When raising seedlings, sow about 1.5 grams of seeds per square meter of seedbed. Because the seeds are very small, to sow evenly, mix the seeds with about 30-50 times fine sand or fine soil and then sow. Cover the seeds with about 0.3 cm of fine soil. Control the ground temperature at 22-25°C; dry seeds emerge in 5 days after sowing.
Ageratum disease control
Ageratum often suffers from root rot, rust, and damage from noctuid moths and whiteflies. For root rot, spray with 1000 times dilution of 10% antibacterial agent 401 acetic acid solution; for rust, spray with 2000 times dilution of 50% carboxin wettable powder.
Distribution range of Ageratum
Ageratum is native to Mexico and is now widely distributed in tropical regions of the Eastern Hemisphere.
It was first recorded in China in G. Bentham's (1861) Flora of Hong Kong, and was discovered in southern Yunnan at the end of the 19th century. It is now commonly distributed in low mountains, hills, and plains throughout the Yangtze River basin and areas to the south. Another species originating from Central America, Ageratum houstonianum, has been introduced and cultivated in southern China for ornamental purposes and often escapes as a weed.
Uses and functions of Ageratum
Ageratum flowers have effects on health: 1. Ageratum flower color stimulates the senses and has an effect on human psychology. Different Ageratum flower colors have different effects. 2. Ageratum flower fragrance stimulates the sense of smell and is very beneficial to health. 3. The aromatic oil of Ageratum flowers can resist bacteria and enhance the human body's immune capacity. According to physiologists' research, the "pheromones" contained in Ageratum flower fragrance have a similar ability to human "sex hormones." 4. Ageratum flowers can purify the air. Research has found that Ageratum flowers have the effect of absorbing and killing toxins and preventing air pollution.
Application Value
Ageratum has lush clumps and elegant flower colors. It is often used to configure flower beds and ground cover, and can also be used as accents in small courtyards, along roadsides, and beside rocks.
