Achene linear, narrowed at the base, 8-12 mm long, black, covered with short pubescence, pappus scale-like, of which 1-2 are long awn-shaped, and 2-3 are short and blunt. Flowering period from July to September.
Pest and disease control of French marigold:
Common diseases include brown spot disease, powdery mildew, etc., which are fungal diseases. A good site should be chosen for cultivation, and attention should be paid to drainage and irrigation, removal of diseased plants and diseased leaves, burning of residual branches, and timely spraying of fungicides such as Xiufenning.
Control methods for stem blight of French marigold
Symptoms: Mainly damages stems and branches. Initially, gray rash-like protrusions appear on the stems, round or spindle-shaped, later the protrusions split open, exposing black acervuli. It occurs from time to time during the growing period. In severe cases, stems and branches die, the growth and development of the whole plant are inhibited, and ornamental value is affected.
Disease characteristics: This disease is caused by fungi. The pathogen is a species of Coryneum, also called Pestalotia-like multi-septate spore fungus. The pathogen overwinters on diseased residues, and in the second year spreads through airflow, infecting healthy plants. It occurs from April to November, and is more severe in rainy areas or rainy seasons.
Control methods:
Horticultural control: Drain promptly after rain to prevent moisture retention.
Chemical control: In areas with severe incidence, spray at the early stage of the disease. The agents can be 25% benomyl + zinc cyclohexyl emulsifiable concentrate at 800 times dilution, 40% chlorothalonil suspension concentrate at 500 times dilution, and 30% Ludebao suspension concentrate at 400 times dilution. Spray once every 7 days, for a total of 2-3 times. [5]
The main pest is red spider mite. Cultivation management can be strengthened. At the early stage of pest occurrence, 20% dicofol emulsifiable concentrate at 500-600 times dilution can be sprayed for control.
Common pests and diseases of French marigold and their control
Common diseases of French marigold and their control
The common diseases of French marigold are mainly brown spot disease, powdery mildew and stem blight, among which stem blight is the most common, mainly damaging the stems and leaves of French marigold. Its symptoms are: at the early stage of the disease, rash-like protrusions appear on the plant stems, gray in color, spindle-shaped or round, and later the rash-like protrusions crack open. Stem blight also occurs from time to time during the growing period of French marigold, and in severe cases can cause the plant to die.
Control methods: (1) Drain promptly after rain to prevent moisture retention. (2) Spray agents at the early stage of the disease. Specific prepared solutions of benomyl + zinc cyclohexyl emulsifiable concentrate, chlorothalonil suspension concentrate and Ludebao suspension concentrate can be selected. The spraying cycle is seven days, and spraying 2-3 times is sufficient.
Common pests of French marigold and their control
The common pest of French marigold is mainly red spider mite. Red spider mite pierces and sucks stem and leaf sap, reducing moisture in the affected parts. Dense pale small spots appear on the leaf surface, leaves curl and turn yellow, and in severe cases the plant develops yellow leaves, curled leaves, scorched leaves, leaf drop, or even death. Red spider mite is also a transmission vector of viral diseases.
Control methods: Strengthen cultivation management. At the early stage of pest occurrence, 20% dicofol emulsifiable concentrate at 500-600 times dilution can be selected for control.
French marigold has certain medicinal value, mainly used to clear heat and detoxify, relieve cough and resolve phlegm, and treat wind-heat common cold, dysentery, parotitis, stomatitis and other diseases.
French marigold has such high medicinal value. Flower lovers should take good care of French marigold and try not to let it suffer from pests and diseases!

Cultivation methods and precautions for French marigold Introduction to French marigold
French marigold aliases: yellow chrysanthemum, five-petal lotus, laolaihong, stinking chrysanthemum, peacock chrysanthemum, small marigold, red-yellow herb, satin flower. It is the whole plant of the Asteraceae plant French marigold. Harvested in summer and autumn, used fresh or dried in the sun. It grows on mountain slopes, grasslands and in forests at an altitude of 750-1600 m, or is cultivated in gardens. It is distributed in Sichuan, Guizhou, Yunnan and other places. Main indications: clearing heat and detoxifying; relieving cough. Mainly treats wind-heat common cold; cough; whooping cough; dysentery; parotitis; acute mastitis; furuncle and swelling; toothache; stomatitis; red and swollen eyes with pain.
French marigold, Yi medicine name Yini Buchiwu: Yi doctors use the flowers or roots as medicine, mainly to treat snake bites, mumps, breast sores, chronic cough, heat cough and asthma, dizziness, common cold with fever and other symptoms, according to "Yi Plant Medicine". The root treats venomous snake bites, according to "Ailao". The whole plant treats upper respiratory tract infections, dysentery, whooping cough, toothache, and parotitis, according to "Dali Local Records".
Morphological characteristics of French marigold
Plant height 30 to 40 cm. Pinnately compound leaves, leaflets lanceolate. Pedicels emerge from leaf axils, capitula terminal, single or double. Flower colors include red-brown, yellow-brown, pale yellow, purplish-red spots, etc. The flower shape is similar to that of marigold, but the flowers are smaller and more numerous. When blooming, on the short, much-branched plant, golden-orange flowers cover the branch tips, appearing gorgeous and lovely. French marigold has good ornamental value and is suitable for pot cultivation, ground cultivation and cut flowers. Leaves opposite, pinnately parted, segments lanceolate, leaf margins with obvious oil gland dots. Capitula terminal, outer ring of flowers dark red, inner part yellow, hence also called red-yellow herb. Because of complex interspecific hybridization, in addition to red-yellow, pure yellow, orange and other varieties have also been bred, as well as single-petaled, double-petaled and other varieties. The flowering period lasts from "May Day" all the way to "National Day".
Annual herb, 30-100 cm tall, stem erect, usually branched near the base, branches spreading obliquely. Leaves pinnately parted, 2-9 cm long, 1.5-3 cm wide, segments linear-lanceolate, margins serrate, tooth tips often with long fine awns, tooth bases usually with 1 gland. Capitulum solitary, 3.5-4 cm in diameter, peduncle 5-6.5 cm long, slightly thickened at the apex; involucre 1.5 cm long, 0.7 cm wide, oblong, upper end with sharp teeth, glandular-punctate; ray florets golden yellow or orange, with red spots; ligules suborbicular, 8-10 mm long, 6-7 mm wide, apex slightly emarginate; disc florets corolla yellow, 10-14 mm long, equal in length to the pappus, with 5 tooth-like lobes. Achene linear, narrowed at the base, 8-12 mm long, black, covered with short pubescence, pappus scale-like, of which 1-2 are long awn-shaped, and 2-3 are short and blunt. Flowering period from July to September.
Ecological habits of French marigold
French marigold is native to Mexico. It is a flower with very strong adaptability. It can also be seen in many places in China, especially more commonly in the south. Its flowering periods are from March to May and from August to December.
Because scarlet sage cannot withstand the low temperature of "May Day", nor the early frost of "National Day", and the intense heat of midsummer can cause most plants to be in a half-dead state. Therefore, French marigold has gradually become a main flower for flower beds and courtyards. Its orange, yellow and red flowers are extremely eye-catching. They add a lot of vitality to wherever they are planted. Its role and value have attracted the attention of many gardening workers.
The seed germination rate of French marigold is low. With ordinary sowing methods, the germination rate is only 10%-30%. To plant French marigold, first use boxes, pots and other containers for seedling cultivation, filled with sandy loam soil, to create a soft, well-aerated germination environment for the seeds. Sow the seeds directly on the soil surface, cover with straw mats or newspaper, and make them closely contact the soil. Water frequently with a spray bottle, and do not let the surface soil dry out. After the seeds emerge, remove the covering.
French marigold has very strong adaptability, can tolerate drought and cold, and can withstand the test of early frost. It can grow on its own and is easy to manage.
Growth characteristics
French marigold is an annual herbaceous flower of the genus Tagetes in the Asteraceae family. The plant is relatively short, 20-40 cm tall, compact in form, much-branched and clump-forming, with purple stems. Leaves opposite, pinnately parted, segments lanceolate, leaf margins with obvious oil gland dots. Capitula terminal, outer ring of flowers dark red, inner part yellow, hence there are also single-petaled, double-petaled and other varieties.
The flowering period lasts from French marigold has strong adaptability, likes warm and sunny environments, is relatively drought-tolerant, and has no strict requirements for soil and fertilizer.
French marigold is relatively cold-tolerant, and it can withstand the invasion of early frost. In the intense heat of midsummer, the number of flowers is relatively small.
The seedling period is short. From sowing to flowering takes only 70 days. Seedlings in early spring can be raised in greenhouses without heating, and after the late frost they can be planted in courtyards, flower beds or pots. In midsummer there are few flowers, so it can be cut back completely once. After the Beginning of Autumn, it can bloom again at the tips of new lateral branches, or it may not be cut back, only the plant will be relatively loose.
It is very easy to degenerate between varieties. French marigold not only has varieties with single petals, double petals, different flower colors and different heights, but also includes the same genus marigold, and natural hybridization between them also easily causes degeneration. Varieties with good flower color should be selected, sown separately and planted separately, and kept more than 100 m away from other varieties.
Seeds should be collected separately and stored separately. French marigold likes sunlight, but it can also bloom when planted in semi-shade. It has no strict requirements for soil. It tolerates transplanting, grows rapidly, and is very easy to cultivate and manage. Seeds that fall on the ground can grow on their own under suitable temperature and humidity conditions. It is a flower with very strong adaptability.
From sowing to flowering takes only 70 days. Seedlings in early spring can be raised in greenhouses without heating, and after the late frost they can be planted in courtyards or pots. It can be sown all year round. However, due to restrictions on flower use conditions, and because sowing French marigold requires a temperature above 15°C (or heating and insulation), the sowing period in the middle and lower reaches of the Yangtze River is generally from August to November. In the warm south, it can be sown all year round, while in the north spring sowing is popular. If raising seedlings in early spring, care should be taken to ensure a certain growth temperature and try to avoid growth stagnation.
For sowing, loose artificial media should be used, with seedbed sowing or box sowing for seedling cultivation, and plug tray seedling cultivation can be used if conditions permit. After disinfection treatment, sow and cover slightly. The suitable germination temperature for French marigold is 22-24°C. At this stage the root system has already formed well. When there are 3 pairs of true leaves, the temperature can be lowered to 15-17°C, but it is best not to be lower than 15°C. However, as in the second stage, the medium should be allowed to dry thoroughly between two waterings, and ventilation should be strengthened to prevent leggy growth.
If seedling cultivation fails or there are problems, the main reasons are: First, the pH value of the medium is too low. The main symptoms are necrotic spots and scorched edges on old leaves, and necrosis of the growing point. Second, a pH value lower than 6.0 can also cause excessive amounts of certain trace elements such as magnesium, iron, sodium and zinc. The main solution is: keep the pH value of the medium between 6.0-6.7, which can be adjusted by adding 0.4526 kg of lime to 38 kg of water; Third, when raising seedlings at low temperature in early spring, if the temperature is too high, damping-off is likely to occur. It initially appears as water-soaked areas at the stem base, then necrosis and lodging. Therefore, attention should be paid to raising the temperature as much as possible and controlling humidity when raising seedlings in early spring to prevent disease occurrence. Fourth, pay attention to nutrition during the seedling stage. If there is a lack of fertilizer and water during the seedling stage and the plant is thin and weak, small old seedlings will form. One week after sowing, the embryo can be seen sprouting. At this time, keep the soil moisture at 75% to 85% to facilitate downward extension of the radicle. When the cotyledons unfold and the first pair of leaves grows, control the seedbed humidity at this time, pay attention to ventilation, and at the same time begin applying water-soluble fertilizer at a concentration of 50 ppm to the seedlings, once every 5 to 7 days. As the second to third pairs of leaves begin to grow, the seedlings enter a rapid growth period.
Cultivation techniques of French marigold Sowing methods
It can be sown all year round. However, due to restrictions on flower use conditions, the demand for flowers is greatest for the two holidays "May Day" and National Day. Also, because sowing French marigold requires a temperature above 15°C (or heating and insulation conditions).
(1) First stage
2-5 days after sowing, the seeds turn white (embryo appears). French marigold seeds do not require light for germination. Usually after sowing, cover with a thin layer of medium, which can both shade light and maintain moisture in the early seedling stage. Keep the medium moist, but prevent excessive moisture, and maintain the temperature at 21-24°C.
(2) Second stage
From emergence of the radicle to full expansion of the cotyledons takes about 7 days. Once the radicle appears, lower the temperature, and water only after the medium is slightly dry to facilitate better germination and root growth. Provide light and apply a small amount of fertilizer.
(3) Third stage
Rapid growth period of seedlings. During the seedling growth of French marigold, prevent excessive humidity, so the medium should be allowed to dry thoroughly between two waterings. Of course, the medium must not be so dry that the seedlings wither. The medium and ambient temperature can be appropriately lowered to 18°C. Fertilize alternately every 5-10 days. If the medium temperature is lower than 18°C, avoid applying ammonium nitrogen fertilizer. In the later part of this stage, the plant root system can grow to 3-5 cm, and the seedlings are 3-4 cm tall with 2-3 pairs of true leaves.
(4) Fourth stage
Hardening-off period, but avoid using ammonium nitrogen fertilizer. As in the second stage, the medium should be allowed to dry thoroughly between two waterings, and ventilation should be strengthened to prevent leggy growth. If seedling cultivation fails or there are problems, the main reasons are: First, the pH value of the medium is too low. The main symptoms are necrotic spots and scorched edges on old leaves, and necrosis of the growing point. Second, a pH value lower than 6.0 can also cause excessive amounts of certain trace elements such as magnesium, iron, sodium and zinc. The main solution is: keep the pH value of the medium between 6.0-6.7, which can be adjusted by adding 0.4526 kg of lime to 38 kg of water; Third, raising seedlings at low temperature in early spring. If the temperature is too high, damping-off is likely to occur. It initially appears as water-soaked areas at the stem base, then necrosis and lodging. Therefore, attention should be paid to raising the temperature as much as possible and controlling humidity when raising seedlings in early spring to prevent disease occurrence. Fourth, pay attention to nutrition during the seedling stage. If there is a lack of fertilizer and water during the seedling stage and the plant is thin and weak, small old seedlings will form.
Maintenance principles
(1) Light regulation
French marigold is a sun-loving plant. Both growth and flowering require sufficient sunlight, and sufficient light also helps prevent leggy growth. In high-temperature seasons, direct sunlight should be avoided, and shading and cooling should be provided around noon.
(2) Temperature control
After potting, the temperature can be lowered to 18°C, and after several weeks it can be lowered to 15°C. Before and after flowering it can be as low as 12-14°C. This temperature is most ideal for forming a good plant shape, but in actual production it may be difficult to achieve this condition. Therefore, generally speaking, as long as it is above 5°C it will not suffer cold damage, and it can grow well between 10-30°C.
(3) Water and fertilizer management
The key to water management is to use a well-drained medium. Although keeping the medium moist is important, proper drying before each watering is necessary. Of course, the medium must not be so dry that the plant withers. For cultivation entirely with artificial medium, fertilize alternately once every 7-10 days. When the winter temperature is relatively low, reduce the amount of fertilizer used. If ordinary soil is used as the medium, compound fertilizer can be mixed in an appropriate amount as base fertilizer before potting. When fertility is insufficient, apply additional fertilizer.
Cultivation steps
(1) Land preparation
Prepare the land and make beds, and apply sufficient base fertilizer. Rationally prepare the land, make beds and apply sufficient base fertilizer. Decomposed organic fertilizer can be applied, such as 1000 kg of chicken manure per mu into the bed, then cover with field soil. Generally the bed height is more than 30 cm, bed width 100 cm, and bed length 20 m or variable, and drainage ditches should be smooth so that accumulated water can be drained promptly after rain.
(2) Planting
Plant the seedlings on the prepared beds. Before planting, first open holes, plant four in each hole, with a plant-row spacing of 30 x 30 cm. After planting, water with settling water so that the soil is firmly combined, keep the soil moist, and promote growth.
(3) Management
After planting, cultivate and weed promptly to prevent soil compaction and weed overgrowth. Because deepening the cultivation promotes roots to grow deeper, generally cultivate 2-3 times before the rows close. After the rows close, there are generally no weeds, ground water evaporation is reduced, and cultivation is not needed. In the early stage, apply fertilizer frequently and lightly, mainly N fertilizer, once every seven days. During the vigorous growth period, from flower bud differentiation and formation to the bud stage, heavy topdressing can be applied, with 50 kg of compound fertilizer per mu, and foliar fertilizer sprayed once a week. Stop fertilizing when the flower buds are about to open.
(4) Light
White French marigold is a short-day plant. Under the short-day conditions after autumn, French marigold will not grow tall and can only tiller underground. The light duration must be extended to stretch the aboveground stem taller. Generally one month after planting, begin artificial supplementary lighting. Usually use 100 W or 60 W light bulbs hung 80 cm above the plants, each lamp illuminating 4 sq m, increasing the lighting time by 4 hours per day for 40 consecutive days, ending 60 days before Spring Festival. The supplementary lighting method can start when it gets dark in the evening, or start 4 hours before dawn.
(5) Harvesting
To make white French marigold cut flowers last longer, the best time to cut flowers is when about 10 flowers have opened on the terminal buds and the others are still in bud. If the weather is hot, it is best to cut flowers when it is cool. After cutting, bring them back to the workroom, grade and package them, tie every twenty stems into a bunch, wrap them in paper, and store them or box them for sale.
Cultivation using cold greenhouses
At 41 degrees north latitude and an altitude of 690 m, French marigold can be sown and propagated all year round, but winter propagation and flower use for "May Day" are the most difficult. The suitable temperature for sowing French marigold is 15°C to 23°C, while below 13°C or above 26°C the plants will show uneven germination and low seedling survival rates. After the seedlings are potted, they grow slowly or wither in patches, and in the end few remain.
In winter, when the temperature is between -12°C and -23°C and the climate is dry, cold greenhouse technology is used in winter: double-layer greenhouse cold protection and heating measures, that is, building an inner greenhouse inside the original greenhouse, canceling the original central heating supply. The application of this technology saves coal and money, and at the same time, the accuracy rate of flowering time and the flowering rate of flowers are significantly improved. The French marigold propagated has a germination rate of 98% and a seedling survival rate of 95%.
1. Sowing
To make French marigold bloom for "May Day", it can be sown in mid-to-late December each year and cultivated in plastic greenhouses, using simple plug tray seedling cultivation. In the initial stage, keep the seedling soil moisture at 85% to 95% to facilitate seed water absorption and swelling. French marigold seeds do not like light, so after sowing they need to be covered with soil, but not too thick, which can improve the germination rate and uniformity of the seeds. In low-temperature weather, after the temperature drops each afternoon, use a sprayer to spray inside the greenhouse to increase air humidity.
2. Seedling stage management
For each additional pair of leaves on the seedlings, increase the fertilization concentration correspondingly by one time, gradually increasing to 200 ppm to 250 ppm. During leaf growth, attention should be paid to alternating dry and wet conditions in the seedbed to promote root growth. In early spring, the temperature is low. Since there are no heating measures, supplementary lighting must be carried out to increase the seedbed temperature and appropriately control moisture. Otherwise, French marigold seedlings are difficult to grow well.
3. Cultivation management
Winter is generally low-temperature and low-humidity weather, which is precisely a difficult period for French marigold growth. Practice shows that if two layers of film protection are used, the survival rate of French marigold is only 25%. If three layers of film protection are used, the survival rate of French marigold seedlings can reach 95.22%. On the seedbed, pot French marigold seedlings with 2 to 3 pairs of leaves into small pots. After the seedlings adapt to the pots, routine water and fertilizer management can be carried out. Because it is protected cultivation, after each watering and fertilizing, ventilation should be strengthened to prevent excessive humidity from causing seedling rot. After Spring Festival, the temperature begins to rise, and French marigold enters a rapid growth period. At this time, the film on the seedbed can be gradually removed, while strengthening fertilizer and water management.
4. Pest and disease control
French marigold mainly has seedling-stage root rot, which can be controlled by drenching the roots with thiophanate-methyl at 800 times dilution.
The main pest is red spider mite damage, which can be controlled by spraying dimethoate at 1500 times dilution.
Disease control of French marigold
French marigold mainly has seedling-stage root rot, which can be controlled by drenching the roots with thiophanate-methyl at 800 times dilution.
The main pest is red spider mite damage, which can be controlled by spraying dimethoate at 1500 times dilution.
Common diseases include brown spot disease, powdery mildew, etc., which are fungal diseases. A good site should be chosen for cultivation, and attention should be paid to drainage and irrigation, removal of diseased plants and diseased leaves, burning of residual branches, and timely spraying of fungicides such as Xiufenning. The main pest is red spider mite. Cultivation management can be strengthened. At the early stage of pest occurrence, 20% dicofol emulsifiable concentrate at 500-600 times dilution can be sprayed for control.
The main reasons for poor summer growth of French marigold are:
(1) French marigold fears high temperatures. During the intense summer heat, growth vigor weakens and the number of flowers decreases.
(2) French marigold grows relatively quickly. French marigold potted in spring begins to age by summer, so even after the temperature turns cool in autumn, French marigold planted in the ground has already recovered good growth and flowering, but potted French marigold will not only fail to improve, but will go from bad to worse.
Therefore, the young branches of French marigold should be cuttings in autumn. One week after cutting, French marigold can take root and be potted. After the autumn cool arrives, it can quickly grow and take shape, and can continuously produce bright flowers.
Propagation methods of French marigold
French marigold can be propagated by both sowing and cuttings. Sowing is carried out from November to March. Sowing in winter and spring results in flowering from March to May. Sowing can be done directly in courtyards or in pots. For pot cultivation, about 1 month after sowing, the seedlings can be dug out and potted for planting. For cutting propagation, from June to August, cut young branches about 10 cm long and insert them directly into the courtyard, with shading and covering, and they grow rapidly. They can also be inserted directly into flower pots. Cuttings made in summer and autumn flower from August to December. Whether inserted in the ground or in beds (pots), cuttings can survive.
For flowers to welcome "May Day" and celebrate "National Day", sow in a greenhouse or indoors in mid-February, and after one transplanting, heel in pots with a diameter of 20 cm. After the late frost, remove the pots and plant in the open field.
Distribution range of French marigold
It is often cultivated in gardens in various parts of China. The main breeding bases include Jiangsu, Zhejiang, Anhui and other places.
Uses and purposes of French marigold
It is most suitable as flower bed edging material or for planting in flower clusters, flower borders, etc. It can also be potted and used as cut flowers.
French marigold has medicinal and health-care effects. The flowers and leaves can be used as medicine, with the effects of clearing heat and resolving phlegm, nourishing blood and promoting menstruation. It can treat whooping cough, bronchitis, and colds. Residents in the Caucasus region of Russia often eat French marigold, which has the effect of prolonging life.
Cultural background of French marigold
Flower of Saint Francis de Sales, a saint of the 17th century
Since ancient times, Christianity has had the habit of linking saints with specific flowers. This originated because when the church commemorates saints, it often decorates the altar with blooming flowers! In medieval Catholic monasteries, various flowers were planted almost like gardening centers. Over time, the church combined the 366 days' saints with different flowers respectively, forming the so-called flower calendar. At that time, most monasteries were located in southern Europe, and southern Europe has a Mediterranean climate, which is extremely suitable for planting flowers and plants. French marigold belongs to the Asteraceae family and is an annual herbaceous plant native to Mexico. It was chosen to commemorate Saint Francis de Sales, who established the feast day of the Virgin Mary.
French marigold originally had a common name called "sunflower". Only later was it "taken over" by the common sunflower. Its flowers have the habit of opening at sunrise and closing tightly at sunset, and they grow in a heliotropic manner. Therefore, its flower language is "clear weather", extended to mean "cheerful and lively". Anyone born under the blessing of this flower never does things sloppily, which is a rare virtue!
