Maintenance and management of potted flowers in autumn

As everything begins to wither in autumn, the conservation of potted flowers needs to be more careful in autumn, so that potted flowers can survive the winter safely. So how to manage potted flowers in autumn?

Potted flower

The climate of watering and fertilization is cool in autumn, the temperature difference between day and night is large, and the water evaporation of potted flowers is slow. Generally, it can be watered once a day, if too much watering, the plant is prone to rot, resulting in leaf yellow shedding; under watering, there will be drooping leaves and weak plant growth. Watering is appropriate to keep the basin soil wet and dry. In autumn, most potted flowers are in a period of exuberance, usually topdressing and ripening dilute liquid fertilizer every 10 days. For potted flowers that bloom in autumn, such as sweet-scented osmanthus, chrysanthemum and dahlia, we should apply less nitrogen fertilizer and more phosphorus and potassium fertilizer to promote them to bloom and grow luxuriantly.

Reasonable pruning in autumn, potted flowers sprout a lot of buds, should be pruned properly so as not to consume nutrients. For the retained branches, leaves should be left to pick buds, plants with strong growth should be cut heavily, and those with weak growth should be cut lightly; potted flowers pregnant with flower buds in autumn, such as plum blossom, wax plum, rhododendron, etc., should not be heavy-cut, but can be treated with coring. Reasonable pruning is beneficial for the plant to accumulate nutrients and lay a foundation for future growth. It can promote the aging of branches and enhance the ability of cold resistance.

After Cold Dew, if the light is insufficient, the temperature is inappropriate, and the fertilizer and water are out of balance, it is easy to make the plant weak. Potted flowers that are afraid of Cold Dew and are not tolerant to low temperatures, such as Milan, Fusang, poinsettia, Michelia, etc., are extremely prone to frostbite, so they should be maintained under the eaves with plenty of sunshine and leeward. When the temperature drops to 5 ℃, move into the sunny place indoors.

The conservation and management of potted flowers in autumn is particularly important for potted flowers, because the climate in autumn changes from hot summer to cool gradually, and potted flowers are likely to wither and wither because they are unable to adapt to the sudden change of climate. therefore, pot flower management should pay attention to the following management work at this time. First, the main points of maintenance of potted flowers in autumn 1. Some light-loving woody flowers that bloom in summer, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place, so that the plants can fully receive light, so that the leaves can better carry out photosynthesis and provide nutrients in time, so as to promote the maturity of branches in the current year, so that they can survive the winter safely, and ensure that flowers and leaves flourish in the following year. Potted flowers such as rhododendron, magnolia, cyclamen, poinsettia and crab claw orchid that bloom before and after the Spring Festival should also be placed in a sunny place and receive full sunshine, otherwise the flowering period will be delayed or even will not bloom. Generally, foliage plants are more shade-tolerant and can provide some light appropriately to avoid direct light at noon. two。 Water and fertilizer appropriate flowers began to control the amount of water in early October, stop fertilization, so as not to water more rotten roots, fertilizer caused branches and leaves to grow, affecting overwintering. Flowers that bloom before and after the Spring Festival, such as cyclamen, orchid, crab claw orchid, rhododendron, etc., have passed the dormant period and began to enter the peak growing season, so the management of fertilizer and water should be strengthened from autumn to Spring Festival, and appropriate application of phosphorus and potassium fertilizer can be added to facilitate the formation of flower buds. 3. In addition to the flowers that bloom in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned and shaped in autumn, which can reduce the consumption of nutrients in winter and increase the number of potted flowers in the following year. Remove diseased branches, withered branches, over-dense branches and overgrown branches when pruning, so as to lay a good foundation for potted flowers to survive the winter. 4. Some biennial flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., are good time to sow seeds. Pay attention to spraying water after sowing to keep the soil moist. There are some woody flowers suitable for cutting in autumn, such as rose, geranium, jasmine, etc., with a higher survival rate in autumn. Perennial root flowers that need ramets for dense growth, such as peony and peony, should be propagated in time. Flowers that bloom before and after the Spring Festival, such as hyacinth, tulips, Zhu Dinghong, etc., should be put on the pot as soon as possible. 5. The time of entering the house in time for potted flowers can vary according to different flowers. Fusang, poinsettia, begonia, cyclamen, jasmine, colourful leaf grass, tortoise back bamboo and other warm flowers and trees should be moved into the room when the temperature is 10 ℃, while orchid, asparagus, one-leaf orchid, goose palm wood, rubber tree, etc., should also be moved indoors at 5 ℃. It is better for most flowers to enter the house in front of Frosts Descent. Second, autumn flower maintenance three timely 1. Some light-loving woody flowers that bloom in summer in time, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place. Flowering rhododendron, magnolia, cyclamen, poinsettia, crab claw orchid and other potted flowers before and after the Spring Festival should also be placed in sunny places. two。 Pruning in time in addition to flowers blooming in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned in autumn, which can reduce the consumption of nutrients in winter and increase the number of potted flowers in the following year. 3. Some biennial flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., are good time to sow seeds. Pay attention to spraying water after sowing to keep the soil moist. There are some woody flowers suitable for cutting in autumn, such as rose, geranium, jasmine, etc., with a higher survival rate in autumn. Perennial root flowers that need ramets for dense growth, such as peony and peony, should be propagated in time. Flowers that bloom before and after the Spring Festival, such as hyacinth, tulips, Zhu Dinghong, etc., should be put on the pot as soon as possible. Cao Qidong, how to manage potted flowers in autumn? 1. The management of water and fertilizer should be treated differently according to the habits of different flowers after the right amount of water and fertilizer in autumn. For autumn chrysanthemum, sweet-scented osmanthus, camellia, rhododendron, wax plum, etc., which bloom once a year, liquid fertilizer dominated by phosphate fertilizer should be applied 2 or 3 times in time, otherwise not only the flowers will be small, but also the buds will fall. For the rose, Milan and jasmine which bloom many times a year, we should continue to provide more sufficient water and fertilizer to promote its continuous flowering. For most flowers, after Cold Dew Festival in the north, there is generally no more fertilization to facilitate overwintering. With the decrease of air temperature, except for the flowers flowering in autumn, winter or early spring and those sown in autumn, which can continue to be watered normally according to the actual needs of each kind of flowers, the watering times and amount of water for other flowers should be gradually reduced to avoid excessive water and fertilizer and cause excessive growth. affect flower bud differentiation and suffer frost injury. two。 When the temperature of pruning and shaping is about 20 ℃ after autumn, most flowers are easy to sprout more twigs. Except for keeping some of them as needed, the rest should be cut off in time to reduce nutrient consumption. The retained twigs should also be plucked in time. For chrysanthemum, dahlia, rose, jasmine and so on, when the buds grow to a certain size after budding in autumn, the lateral buds are removed except for a large bud with good growth at the top. 3. The seeds of many flowers are harvested in time, which mature one after another before and after mid-autumn and need to be harvested in time. A bunch of red, pineapple, morning glory and other seeds are dried after harvest and stored in a cloth bag in a low-temperature ventilated place. For some seeds with thick seed coat, such as peony, peony, magnolia, Michelia, etc., the seeds should be buried in wet sand and stored in stratified sand after harvest. 4. It is appropriate to sow biennial or perennial grass flowers cultivated in one or two years, such as goldfish grass, carnation, daisy, greenhouse flowers such as Chrysanthemum, cyclamen, tree tree and other greenhouse flowers, as well as African chrysanthemum, swallows, primroses, begonias and other flowers that are easy to lose their ability to germinate after harvest. 5. After entering the house at the right time, most of the flowers in the northern area after Cold Dew's festival should be moved indoors one after another to survive the winter according to the cold resistance, so as to avoid cold damage. The specific time to enter the room varies from time to time. For most flowers, don't rush into the house as soon as the weather has just changed. Because entering the house too early affects the accumulation of nutrients, which is not conducive to the growth and development of the coming year. Therefore, under the premise of not suffering from cold injury, it is better to enter the room a little later. Key points of conservation and management of potted flowers in autumn the temperature gradually drops and the sunshine weakens after the beginning of autumn. for many citizens who like to grow flowers, they need to maintain the flowers according to the climatic characteristics of this season to make them spend the autumn and winter smoothly. After the Beginning of Autumn, the weather gradually turned cooler. For some foliage flowers, such as asparagus, hanging orchid, cycad, etc., thin liquid fertilizer is generally applied every half a month to keep the leaves green and improve the ability to protect against the cold. For chrysanthemums, camellias, rhododendrons, etc., which bloom once a year, it is necessary to apply phosphate-based liquid fertilizer in time to ensure sufficient nutrients and make them bloom more and more. Rose, Milan and jasmine, which bloom many times a year, should be provided with enough fertilizer and water to make them blossom continuously; for some ornamental flowers, such as kumquat, bergamot, pomegranate, etc., thin liquid fertilizer dominated by phosphate fertilizer should be applied twice. With the gradual decrease of air temperature, except for the normal watering of autumn-sown grass flowers blooming in autumn, winter or early spring, the watering times for other flowers should be reduced to avoid excessive water and fertilizer, resulting in excessive growth of branches and leaves, affecting flower bud differentiation and freezing injury. The main points of conservation and management of potted flowers in autumn 1. Indoor heat preservation this season should move most of the woody flowers, bonsai and southern perennial herbs into the room, such as banyan, mulberry, poinsettia, begonia, cyclamen, tortoise back bamboo, goose palm wood, African jasmine, Milan, rubber tree and so on. Because as the temperature difference between day and night increases and the night temperature decreases, perennial flowers in this case will convert the chlorophyll in the body into anthocyanins and carotene, producing defolic acid. Although the plant will not die, it will also cause a large number of fallen leaves or leaf yellowing and other phenomena, losing the ornamental effect. The main points of maintenance and management of potted flowers in autumn 2. Proper water and fertilizer for potted flowers grow slowly in autumn. most flowers should control the amount of water and stop fertilization from this time to avoid rotting roots and causing branches and leaves to grow too much. As for the flowers that bloom before and after the Spring Festival, such as cyclamen, orchid, crab claw orchid, camellia, rhododendron and so on, they have passed the dormant period and began to enter the peak growing season, so fertilizer and water management should be strengthened after autumn, and appropriate application of phosphorus and potassium fertilizer can be added to facilitate the formation of flower buds. Key points of conservation and management of potted flowers in autumn 3. Timely breeding for annual herbaceous flowers, attention should be paid to collecting and preserving seeds. Some biennial flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., are good times to sow seeds. Pay attention to spraying water after sowing to keep the soil moist. There are some woody flowers suitable for cutting in autumn, such as rose, geranium, jasmine, etc., with a higher survival rate in autumn. Perennial root flowers with dense growth and need ramet, such as peony, peony, etc., should be propagated in time. Flowers that bloom before and after the Spring Festival, such as hyacinth, tulips, Zhu Dinghong, etc., should be put on the pot as soon as possible. It is necessary to sow autumn planting in time, harvest mature flowers and trees in time in autumn, sow tulip, paulownia, goldfish grass and so on in time, especially those seeds that are easy to lose their germinating power, sow in time in autumn, and combine pruning and cutting flowers and trees. Such as cutting rose, rose, rose and so on, the survival rate is higher. Key points of conservation and management of potted flowers in autumn 4. Reasonable pruning of most flowers such as jasmine, crape myrtle and pomegranate can be pruned and shaped in autumn, which can reduce nutrient consumption in winter and increase flowering in the following year. Remove diseased branches, withered branches, over-dense branches and overgrown branches when pruning, so as to lay a good foundation for potted flowers to survive the winter. Fifth, the prevention and control of diseases and insect pests in autumn is an important period for the prevention and control of flower diseases and insect pests. Before potted flowers enter the house, medicine can be sprayed to prevent overwintering diseases and insect pests.
