Management methods and maintenance points of Rhododendron in Autumn

How to take care of the azaleas when the temperature is low in autumn and winter? How to maintain it? Generally speaking, the leaves of azaleas are greener and the flowers are very bright and beautiful. they have always been known as Xi Shi in flowers, and they also symbolize happiness. Many people keep several pots in their homes.

Although the azaleas are beautiful, it takes some work to preserve them. In summer, azaleas are suffering from high temperature, difficult to survive, the cool September comes in a twinkling of an eye, and it is the peak growing season of rhododendrons. At this time, we should seize the golden opportunity and manage them reasonably in order to open fireworks in the coming year.

When managing azaleas in autumn, we should pay attention to the following points:

First, it is necessary to see the light reasonably. When the azaleas arrive in September, the weather slowly begins to cool. At this time, in the morning and afternoon, let the azaleas see more of the sun and be nourished by the sun. However, the noon temperature in September is still very high, so it is necessary to cover the sun a little to avoid sunburn. After doing so, the rhododendron will accumulate nutrients, the leaves will be thick green, and can promote the differentiation of flower buds, making the rhododendron more beautiful and more attractive.

Second, it is necessary to water and spray water rationally. in September, the roots of rhododendrons begin to regain their vitality. in addition, the temperature in September is slightly higher and the evaporation is relatively high. at this time, you can pour a little more water to make the soil a little moist. However, in October, when the temperature begins to decrease, the activity of the root system decreases, so don't pour too much water, lest you can't accept it and impregnate the root system.

In addition, because the air is slightly drier, and azaleas prefer higher air humidity, so we have to spray more water around the flowerpot to maintain air humidity. Practice has proved that spraying more water can make rhododendron leaves moist and green, charming posture, and prepare for flower bud differentiation in the coming year.

Third, rational fertilization should be given to azaleas. September and October is the critical period of flower bud differentiation, when a small amount of mature organic fertilizer, or a small amount of mature liquid fertilizer, and a small amount of phosphorus and potassium fertilizer can be used to promote growth and flower bud differentiation. Must not nitrogen fertilizer too much, lest only grow, affect flower bud differentiation. In the middle of October, the weather gets cooler and the roots can't be absorbed, so don't apply fertilizer to avoid eroding the roots.

Fourth, it should be pruned reasonably. In autumn, we can take advantage of the time to cut off some diseased branches, weak branches and residual branches, which can not only maintain a beautiful shape, but also reduce the consumption of nutrients, so that the coming year will blossom better, bloom bigger and blossom more beautifully.

These are the guidelines for the conservation of azaleas in autumn. in addition, we should pay attention to the fact that azaleas are generally not resistant to drought. Don't put them outdoors after mid-October. You can move indoors. The autumn and winter season is well managed, and the flowers will be in full bloom next year.

Key points of maintenance and management of flowers in autumn

In autumn, with the gradual cooling of the temperature, the management of autumn flowers should be moved timely according to the changes of the weather, always pay attention to the temperature difference, moisture, light, branch and leaf pruning and other factors, and timely adjust the treatment, which is conducive to the good growth of autumn flowers. In addition to the normal watering of autumn-sown grass flowers that bloom in autumn, winter or early spring, other flowers should reduce the number of watering, so that the basin soil is not dry and not watered, so as to avoid excessive water and fertilizer, resulting in excessive growth of flower branches and leaves, affecting flower bud differentiation and freezing injury. In order for flowers to survive the coming winter safely, the maintenance and management of flowers should be done well in autumn.

(1) Water and fertilizer. The most important link in the maintenance and management of flowers in autumn is the control of water and fertilizer. Appropriate amount of water and fertilizer should be applied at the beginning of October to avoid rotting roots and causing branches and leaves to grow and affect 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. The time of watering should be in the morning and afternoon in autumn.

(2) temperature. When entering the house, it can be treated separately according to different varieties of flowers. Warm flowers and trees such as Fusang, poinsettia, begonia, cyclamen, jasmine, colored leaf grass, tortoise back bamboo, etc. should be moved into the room when the temperature is 10 ℃; hanging orchid, asparagus, one-leaf orchid, goose palm wood, rubber tree and so on. Also move into the room when the temperature is 5 ℃. It is better for most flowers to be in Frosts Descent's predecessor's room.

(3) pruning. Regular pruning is an important part of flower management in autumn. Most flowers, such as jasmine, crape myrtle and pomegranate, can be trimmed in autumn, which can reduce the consumption of nutrients in winter and increase the number of potted flowers 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) Light. Different flowers, due to different degrees of preference for light, should pay attention to the influence of daily light on different flowers, such as jasmine, Fusang, Jiuli incense, etc., which belong to summer light-loving flowers and trees, which should still be placed in a place with plenty of sunshine to make the plants fully accept the light. promote the current year's branches to mature and survive the winter safely. Cuckoo, gentleman orchid, cyclamen, poinsettia, crab claw orchid and other potted flowers all bloom before and after the Spring Festival, and should also be placed in a sunny place to receive all-day sunshine, otherwise the flowering period will be delayed or even will not bloom. Generally, foliage plants are more shady and can provide some light appropriately.

(5) reproduction. 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.

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.
