Guide to propagation methods and daily maintenance of marigold

How to grow marigold? Marigold has a special nickname called "stinky hibiscus". Marigold is often sown in spring. Because of its large flowers and long flowering period, it is often used in flower bed settings. Let's take you to learn the guidelines for the conservation of marigold flowers.

1. Monitoring efficacy

Marigold can monitor sulfur dioxide and ozone. Its response to the above two gases is very sensitive, when attacked by sulfur dioxide, its leaves will become gray-white, irregular spots appear between the veins, gradually lose green and yellowing; when attacked by ozone, its leaf surface will become waxy, appear necrotic spots, become white or brown after drying, and become red, purple, black, brown and other colors, and wither ahead of time.

two。 Maintenance guide

(1) selecting basin

Planting marigold had better choose plain fired pottery basin, plastic basin is also available, with porous basin is suitable.

(2) soil selection

Marigold has no strict requirements on soil, but it grows best in sandy loam soil with loose soil, fertility and smooth drainage, and the soil is best fine and fine.

(3) cultivation

Cut the young branches into 10cm long cuttings, leaving 2 leaves at the top, and the cut should be smooth. 5g rooting powder, l-2kg mixed with water and 50% carbendazim wettable powder were mixed into the seedling soaking solution, and the cuttings were inserted into the pot soil immediately after invading the medicine, and the depth was about 1 inch and 2 pots high. Gently compact the basin soil, and then pour through the water.

(4) Lighting

Marigold likes sunshine, and plenty of sunlight can significantly improve the quality of flowers.

(5) temperature

The suitable temperature for the growth of marigold is 15-25 ℃, and the winter temperature should not be lower than 5 ℃. When the summer temperature is higher than 30 ℃, the plant will grow wildly, making the stem and leaf not compact and flowering less; when the temperature is lower than 10 ℃, the plant can also grow, but the growth rate will slow down.

(6) watering

Marigold watering time and water should be appropriate, do not accumulate too much water, so that the soil is in a slightly wet state. The young marigold plants just planted should be sprayed 2-3 times a day in hot weather to keep the basin soil moist. Watering marigold should be based on the principle of "seeing dampness".

(7) fertilization

Marigold blossoms for a long time and requires more nutrients. It likes potash fertilizer, the application ratio of nitrogen fertilizer, phosphate fertilizer and potash fertilizer should be 15:8:25, and the internal demand of topdressing fertilizer is about every 15 days during the growing period. At the peak of flowering, 0.5% potassium dihydrogen phosphate can be used to fertilize the leaf surface.

(8) Reproduction

Marigold can be propagated by sowing or cutting. When sowing and breeding, it can be carried out in a year. When using cuttage propagation, it is appropriate to carry out in May-June, when the plant is easy to survive.

(9) pruning

The flowering time of marigold is longer, and the branches and leaves of the plant are dry and senescent in the later stage, which is easy to be crooked, which is not conducive to appreciation. Therefore, it is necessary to remove the unfallen flowers from the plant as soon as possible and apply fertilizer as soon as possible to promote the plant to blossom again.

(10) arrangement and arrangement

The flowering period of marigold is relatively long, potted plants can be placed on the windowsill, desk, case table, or a single branch can be made into a cut flower vase.

The above is the daily maintenance guide for marigold flowers, if you also plant marigold, then quickly come to Huinong net to learn breeding methods!

Guidelines for the maintenance of Flower cultivation in February, the temperature began to pick up, but very slowly, there was still a cold spell, and the weather was cold and rainy. 1. Continue to do a good job in preventing the cold of flowers. 2. According to the development of Narcissus, corresponding measures should be taken in time to adjust the growth process and make Narcissus blossom on time during the Spring Festival. When the water culture time of daffodils is too late or the weather is too cold, measures should be taken to increase temperature and promote flowers, such as putting it in a sunny place on the windowsill during the day (it should be moved into an indoor warm place at night), adding warm water in the basin, covering plastic bags, etc.; when the daffodils grow too fast, they should cool down to slow down their growth, such as proper shade, window ventilation and so on.

3. Continue to reshape and turn the bonsai of coniferous and deciduous broad-leaved trees. 4. Field mining of stump materials. After late February, the weather turned warm and there was no cold current, so coniferous trees and deciduous broad-leaved trees could be excavated in the field. The stumps dug in the field should have more lateral roots, pruned due to posture, properly stored, and planted with transportation to ensure the survival rate of planting. 5. The sap of pine trees such as Pinus elliottii and Pinus elliottii begins to flow, and abdominal grafting culture can be carried out in late February. The 2-month-old black pine is selected as the rootstock, and part of the branches and leaves of the rootstock are cut off before that. The scion chooses 1-2-year-old stout branches. When grafting, one side of the lower end of the scion will be cut by about 1.5 cm, and the other side by about half cm. Then make an oblique incision on the rootstock that is slightly longer than the long slope of the scion, with a depth of 1 to 2 of the coarseness of the grafting site, and the incision should be as close to the root as possible. Finally, insert the scion into the incision of the rootstock, align the cambium of the two to make it completely match, and bind it with plastic film. 6. turn the basin of rhododendron, elm, sparrow plum, Tianzhu, rose, kumquat, etc., and cut off withered branches, disease and insect branches, weak branches, overdense branches, overlapping branches, bifurcated branches and overgrown branches. Elm, sparrow plum and other stump bonsai thinning and cutting the branches in the branches, so that the twigs in the branches are moderately dense, the upper and lower parts of the branches do not overlap, and the left and right do not bifurcate, and at the same time, the twigs in the branches show the shape of dragon claw curved iron and reveal the ancient state, thus increasing the aesthetic value of the pile trees; if the branches of Tianzhu bonsai grow too high and affect the composition needs, the branches should be short to the appropriate proportion. Because of the strong sprouting power of Tianzhu, new buds can sprout anywhere under the cut. The weather characteristics of February: this month is the last month of winter and the cold time of the year, second only to January. By the end of February, the weather began to warm and transition to spring, and a considerable number of flowers began to turn from winter dormancy to recovery. The flower events this month mainly include the following aspects: first, continue to do a good job in cold protection and heat preservation of potted flowers in protection facilities; second, do a good job in pruning and changing pots of some woody flowers after flowering; third, do a good job in the preliminary preparations for cutting, grafting and sowing seedlings of some flower species. First, flower culture 1. Sow seeds. The kinds of flowers that can be sown in the greenhouse or greenhouse in February are: calendula, cyclamen, dwarf sunflower, asparagus, crabapple, red and blue flower, cornflower, chrysanthemum, wheat straw chrysanthemum, string red, marigold, peacock chrysanthemum, petunia, Ling Ling grass, Fu Lukao, Prunus chinensis, moth butterfly, goldfish grass, golden lotus, pansy and so on. The seeds that can be sown in the open field at the end of February are Magnolia, Michelia, heather, maple, begonia (Rosaceae) seeds that have been cracked by sand storage treatment, as well as camphor, Liriodendron chinense, privet, rich seeds, fire thorns, palms, Koeluan trees, disease-free seeds, seven-leaf trees, cloves, etc.; seeds such as Chimonanthus praecox, Chimonanthus chinensis, and wisteria should be soaked for 24 to 48 hours, wait for the seeds to absorb enough water before sowing. Late fragrant jade bulbs and red bulbs can also be planted in greenhouses or greenhouses in February. two。 Cuttings. The species of woody ornamental plants that can be cut in the open field or covered with plastic film in February are as follows: plum blossom (palace powder, green calyx and other varieties cut off annual branches after flowering), Phyllostachys pubescens, hibiscus (southern), crape myrtle, Ruixiang (southern), fragrant, pomegranate, golden bell, welcome spring, Jasminum, June snow, hibiscus, hypericum (plum), Spiraea, ten great efforts, yellow poplar, oil hemp stalk and so on. The branches of lilac and Lingxiao hidden in sand can also be cut at this time. In the first ten days of February, we can continue to cut the branches such as sea immortal flower, Shu Shu, eight immortal flower, Tamarix, Fatong, grape, fig and so on for storage treatment for cutting at the end of March. The ornamental plants that can be cut indoors in February are: Fusang, triangular flower, African violet (leaf cutting), bamboo crabapple, red-backed cinnamon, a string of red, geranium, jasmine, pearl orchid, bergamot, jade tree, jade leaf, stone lotus, epiphyllum, lotus flower, cold water flower, rooting on the ground, longevity flower, Rieger begonia, dragon spit bead, goose palm wood, Guangdong evergreen, Zhu Jiao and so on. 3. Grafting. One-year-old sturdy seedlings of Pinus elliottii were used as rootstocks indoors, and Japanese five-needle pine, brocade pine and white pine were grafted, and then covered with film to keep warm and moisturizing. One-year-old seedlings such as apricot and hairy peach were used as rootstock to cut and breed red leaf plum, plum blossom, green peach, Birthday Bun with Bean Paste Filling, purple leaf peach and so on. In the south of the Yangtze River, when the leaf buds on the branches of Chimonanthus przewalskii grow to the size of the wheat grain, the seedlings of Chimonanthus praecox with a diameter of about 0.8 to 1.2 cm are used as rootstock, and excellent varieties such as "Suxin", "Xinkou" and "Tiger's foot" are cut and bred, and the bagging inflatable and moisturizing measures are adopted, and the survival rate is higher. Taking the sturdy branches of rose "Elizabeth" as rootstock, cutting or splitting the scion of rose, and adopting the measures of first grafting and then cutting and then covering with plastic film to keep moisture and cold, the survival rate of grafting can be greatly improved. 4. Press the strip. The ornamental plant species feasible for strip culture in February are: plum blossom, wax plum, pedicel begonia, sweet-scented osmanthus, purple magnolia, gardenia, brocade flower, Luohan pine, emerald cypress, snowball, Qionghua, spring, golden bell, hypericum, eight immortal flowers, hemp leaf hydrangea, snow spray, red maple, Michelia mollissima and so on. 5. Ramet. The herbaceous flower species that can be cultivated in February are: Iris, Shegan, onion orchid, Ophiopogon, auspicious grass, evergreen, purse peony, hairpin, purple calyx, small Taran, pineapple, purple back evergreen, Jianlan, Chunlan, Cymbidium, kidney fern, hanging orchid, ground rooting, canna, bamboo taro, tortoise back bamboo, synthetic fruit taro, crane orchid, gentleman orchid, aloe and so on. The woody flower species that can be cultivated in February are: Phyllostachys pubescens, hibiscus, Hypericum, Ten Gonglao, eight Immortals, Begonia, Jiexiang, Yingchun, Admiralty, Canary, Snow spray, Safflower Spiraea, Jasmine, Pearl Orchid, Tiger thorn, Purple Magnolia, four Seasons Cinnamon, Phoenix tail Bamboo, Phyllostachys pubescens and so on. Second, harvest seeds and transplant 1. Gather seeds. The seeds of Phyllostachys pubescens, holly, rich seeds and winter corals can be picked in February, and the seeds can be sown after the seeds are exposed to white. Artificial pollination can be given to the plants of Cymbidium in full bloom in greenhouse in order to obtain seeds with better genetic quality. In February, we should pay attention to check the seeds of all kinds of flowers and trees stored in sand to see if there is mildew. If mildew occurs, it should be cleaned in time; if the seeds are found to be dry, they can be properly sprayed with water to maintain a certain degree of humidity in the sand and seeds. If it is found that there are a small number of cracks in the seeds, they should be sown in a relatively short time. Once the radicle stretches out too long, it is easy to break the radicle and affect the emergence rate of the seed. Large seeds in sand storage can be sowed on demand, while small seeds can be sowed in strips or rows. After sowing, pay attention to covering grass or plastic film to protect moisture and prevent cold. two。 Transplanting and planting. In February, the soil in the south is not frozen and the temperature is high. The feasible transplanting species of grass flowers are: Carnation, goldfish grass, hollyhock, silver edge holly, daisy, calendula and so on. In February, most deciduous shrubs and some evergreen tree species can be planted. Among them, deciduous species such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, maple, wisteria, crape myrtle, wax plum, plum blossom (before germination), magnolia, disease-free, acacia, seven-leaf tree, red-leaf plum, cherry, papaya, Lingxiao, Linden, Liriodendron, green peach, Chinese tallow, Spiraea, three branches, Shu Shu, Robinia pseudoacacia, dragon claw Robinia pseudoacacia, Yu Li, elm leaf plum, hypericum (plum), weeping willow, golden silk willow, wood hibiscus, hibiscus, Yellow peel, persimmon, apricot, etc. Evergreen tree species such as Michelia, camphor, du ying, Fa Qing, run nan, purple nan, etc., can be delayed until the end of February to early March; sweet-scented osmanthus, privet, Shu juniper, dragon cypress, Platycladus orientalis, black pine, etc., should be pruned appropriately. Third, flower management 1. Keep out the cold. The weather is still cold in February. After two months of indoor (greenhouse) maintenance, the nutrient consumption of potted ornamental plants is large, and the resistance of flowers and plants is greatly reduced, so we should continue to do a good job of moisturizing and cold protection. If there are heating facilities in the greenhouse or greenhouse, you should continue to give heating and prevent harmful gases or smoke from escaping into the greenhouse or greenhouse; if you hang grass curtains on or around the top of the greenhouse, you can continue to hang grass curtains; and when you encounter the sudden cooling weather after snow, you can't take it lightly. Overwintering potted flowers shelved in protective facilities should continue to do a good job of ventilation, especially at the end of February, the ventilation time can be extended during the time of the highest temperature of the day. It is worth noting that indoor potted flowers bask in the sun, it is best to put them on the inside of the south window, do not open the window. A small number of cold-averse flowers planted in the family, such as Milan, Phalaenopsis, peacock taro, synthetic taro, iron cross begonia, variable leaf wood, pink daiye, etc., in particularly cold weather, you can add plastic bags at night, or leave them in the toilet, turn on heating appliances such as "bath tyrants" and other heating to ensure that they can survive the winter safely. two。 Water it. In February, due to the low temperature, most of the potted flowers can keep the potted soil moist and be able to survive the winter safely, because at this time, the root growth stops, the metabolism is at a low level, and less water is needed. Once there is stagnant water in the potted soil, it is very easy to cause rotten roots to die. In relatively dry rooms, foliar spraying and spraying should be carried out frequently to increase the air humidity of the local environment. If the indoor air is too dry, the light ones will cause the leaves to lack green and lose color, the buds will stop growing, and the heavy ones will dry up and wrinkle, and the buds will shrink and fall off, such as camellia, tea plum, rhododendron, plum blossom, dai dai, kumquat, winter coral and so on. In addition, it is also required to ensure that the water temperature of watering or spraying is basically consistent with the indoor air temperature and soil temperature in the shed. For those potted plant species that will bloom before and after the Spring Festival, such as melon and leaf chrysanthemum, primrose, longevity flower, camellia, tea plum, Belgian rhododendron, calendula, etc., fruit ornamental plants such as firethorn, bamboo, daidai, bergamot, lemon, rich seeds, tangerine, winter coral, not only keep the potted soil moist, but also spray water on leaves, buds and fruits. Only in this way can the leaves be green, the flower buds expand rapidly and the fruit be colorful. Especially for peony, plum blossom, sticking stem begonia, vertical silk begonia and so on placed in the greenhouse, the branches must be sprayed once or twice a day to accelerate the expansion of their buds, so that they can spit out fragrant flowers as scheduled. Buy back the Cymbidium cultivated in the greenhouse, because the temperature and humidity in the greenhouse is quite different from that in the family, if the leaves are not often sprayed with water, the leaves will often shrink and wither. Potted plants and bonsai placed in the air-conditioning room, especially the Japanese five-needle pine bonsai, must ensure that the potted soil is moist and spray water to the plant once or twice a day, otherwise it is very likely to cause plant death. Although the vast majority of potted flowers do not need much water in February, inspection should be strengthened, especially if the temperature continues to rise for several consecutive days, and supplementary watering and spraying should be strengthened in time. In February, green trees and flowering shrubs transplanted in autumn and winter should be watered in time, especially for those evergreen trees and flowering shrubs, foliar spray should be given properly around noon in fine weather to prevent the leaves from drying and falling off, affecting the recovery of growth in spring. 3. Fertilize. In February, we can continue to apply base fertilizer to most green trees and flower shrubs planted on the ground, such as cake manure, barnyard manure, chicken feces and pigeon manure, pond mud, septic tank cleaning, etc., and cover the soil after digging annular grooves from the periphery of the plant root system to meet the needs of plant growth, flowering and fruiting in spring and summer. In February, potted flowers placed in 10 ℃ to 15 ℃ greenhouses (greenhouses), such as camellia, tea plum, melon and leaf chrysanthemum, primroses, cyclamen, Belgian rhododendron, shrimp flowers, golden bracts, Ruixiang, plum blossoms, European daffodils, hyacinths, tulips, crab claw orchids, lotus flowers, colorful pineapples, iron orchids, fruit vines, magnolia, etc., can continue to apply low concentrations of potassium dihydrogen phosphate. In order to facilitate the growth of the plant and bud flowering. For most of the potted flowers, foliage plants and stump bonsai placed in the greenhouse, including small, miniature bonsai, as they are still dormant, fertilizer should be stopped, otherwise it is easy to cause rotting roots of the plant to die. 4. Trim. In February, the ground or potted plum blossom, wax plum, golden bell, and spring after flowering can be shrunk intensively. The branches that have flowered only retain 2 to 3 buds at the base, and the rest are all cut off to promote them to send more new shoots in the same year, and the branches will be more dense in the coming year. In addition, the long branches, dead branches and irregular branches should be pruned together. The species of tree stump bonsai dominated by scissors, such as hammer elm, Finch, banyan, triangular maple, Fujian tea, oak, white wax, bayberry, Elaeagnus angustifolia, wolfberry, holly, June snow, juniper, juniper, etc., continue to prune the pile head that has not been changed for 1 to 2 years. 5. Change the basin. At the end of February and the beginning of March, it is a favorable time for most potted ornamental plants to change pots, usually when the winter dormancy of plants is coming to an end, the root system resumes growth, but the leaf buds have not yet sprouted. The flower species that can be changed at the end of February are: Fusang, geranium, Milan, Magnolia, jasmine, pearl orchid, dichromatic jasmine, red back cinnamon, kidney fern, tortoise back bamboo, rubber tree, hanging bell begonia, bamboo crab crabapple, four seasons begonia, colored leaf begonia, spring orchid, cymbidium, Jianlan, iron tree, gentleman orchid, 12 volumes, aloe, crab claw orchid, lotus flower, Jingtian, jade tree, jade leaf, longevity flower, Zhu Dinghong, asparagus, hanging orchid, Nanyang fir, Goose palm wood, evergreen, crane orchid, shrimp flower, golden bract, coral flower, Longtuzhu, camellia, tea plum, sticking begonia, eight immortal flowers, southern bamboo, variable leaf wood, fruit taro, bamboo taro, rich seeds, fire thorns, daidai, kumquat, bergamot and so on. 6. For the prevention and control of powdery mildew in the leaves of melon and leaf chrysanthemum planted in greenhouse and Botrytis cinerea on primrose leaves, 1500 times of methyl thiophanate wettable powder was sprayed at the initial stage of the disease, once every 10 days. 2 to 3 consecutive sprays can treat Botrytis cinerea on potted cyclamen leaves and Corolla in the greenhouse. The Belgian rhododendron potted in the greenhouse should be sprayed with 1000 to 1500 times of the wettable powder (mainly isocarbamide), and foliar fertilizer such as "multi-effect good" should be stopped, because at this time, the temperature is low and the humidity in the greenhouse is high. It is difficult to absorb foliar spraying, and the reverse side is easy to breed mold on the leaf surface, and in serious cases, it will form ugly disease spots. For aphids, scale insects, ants and coal fouling diseases on potted flowers (such as daidai and kumquat) in the greenhouse, they can be brushed away with a hairbrush when they are small, and those with a large number of insects can be sprayed 2000 times with omethoate EC. After aphids, scale insects and ants are killed, coal fouling disease will also be eliminated. The insect bodies on potted flower plants in the greenhouse, such as pink Tamarix, white shield scale, oyster shield scale, black brown shield scale, etc., can be brushed with a hard hair brush, or killed with cotton stick alcohol, or 2500 times of 2.5% kungfu EC can be sprayed, or 3% carbofuran and 20% Tiemiak granules can be buried in the flowerpot. Continue to clean up the dead branches and leaves under the flowers and trees, and burn the diseased leaves on the potted flowers and plants, which can significantly reduce the occurrence of diseases and insect pests in the coming year. 7. Compost. Pour the tea seed cake, rapeseed cake and bean cake into the pool or tank, inject clear water and carry out sealed fermentation, so as to be used to irrigate potted flowers after dilution in the growing season. Or the cake fertilizer is piled up and fermented, spread out and dried after about 2 months, and then packed in a plastic bag after being fully dried. The granular powder of cake fertilizer dried after drying is spread in the flowerpot as topdressing. For Cymbidium, Jian Orchid, Cymbidium, Phalaenopsis, Cartland and other potted flowers, it is more convenient than pouring liquid cake fertilizer, especially raising flowers on the balcony, which is not only convenient and hygienic, but also can reduce the occurrence of foliar diseases. In addition, it can also be used for the preparation of culture soil. 8. Reclaim frozen ponds. In the first ten days of February, the unfinished ploughing garden can be reclaimed, frozen over the winter, and then trenched to make a bed for raising seedlings or transplanting flowers and trees in spring. The plant species that can be used for flat modeling in February are Cuibai, Luohan pine, Sabina vulgaris, Platycladus orientalis, Platycladus orientalis, Sabina vulgaris, ginkgo, June snow, ground cypress, five-needle pine, yellow mountain pine, black pine, thousand-headed red pine, bayberry, golden finch, small money plum, wax petal flower, sticking begonia, crape myrtle, banyan tree, elm, triangle maple and so on. The plants modeled 1 to 2 years ago were re-banded and adjusted, and it was found that the plants had concave constrictions. The metal or non-metallic wires should be released and replaced with new binding materials for flat binding and fixation. For shallow pot tree stump bonsai, landscape bonsai, small miniature bonsai, stone bonsai, etc., continue to do a good job of heat preservation and cold protection, so that they are always in an environment of no less than 0 ℃, so as to prevent plants from freezing to death or artificial cemented rocks from being frozen and disintegrated, resulting in unnecessary losses. May Garden Flower Conservation Guide May Garden Flower arrangement

In May, when the flowers and trees suitable for display in the courtyard enter the turn of spring and summer, the temperature in all parts of the country has risen greatly, and the sun is getting stronger day by day, so there are more species of potted ornamental plants that can be displayed in the courtyard. Such as rose, Nanyang fir, Tripterygium, Canadian jujube, rubber tree, five-needle pine, Luohan pine, southern bamboo, Zhu Dinghong, jasmine, palm bamboo, cycad, king coconut, sunflower, mottled clover, palm, wine bottle coconut, cinnamon, beautiful needle sunflower, European spring, lily (dwarf potted plant), pomegranate, peony, Michelia, red maple, Milan, four seasons cinnamon, daidai and so on.

The propagation of flowers in the courtyard in May

1. Sowing seeds

The species of grass flowers suitable for sowing in May are: spring of the four seasons, impatiens, thousand-day red, and so on. The woody flowers are: loquat, star anise gold plate, broad leaf ten meritorious works, loose tail sunflower, wine bottle coconut, sweet-scented osmanthus, among which the seeds of the first five kinds of flowers can be picked and sown after washing, but the fruits of sweet-scented osmanthus are black, soft and white when they are ripe, and after washing off the peel and flesh, they should be stored in clean wet sand until February of the following year, and then sow when the seeds are exposed. When picking and sowing seeds, we should pay attention to the following points when sowing: first, to keep the seedbed moist, but not stagnant water; second, to cover the grass to prevent the seeds from "budding"; and third, to remove the covered grass 2 to 3 times after seed emergence, and set up a shed in time to shade the young. In addition, although loquat is a large seed, but its bud top soil ability is weak, easy to bend, sowing too deep will affect the emergence rate and seedling rate, so it is appropriate to shallow sowing, generally ditch depth of 2 to 3 cm to cover soil to ditch full.

At this time, the gladiolus bulb planted in the ground can blossom in August, and the evening jade in the ground can blossom from August to September.

two。 Cuttage
