Some flower friends like to cultivate hollyhocks at home, so what problems should be paid attention to in artificial cultivation of hollyhocks?

Hollyhock (details)

Hollyhocks like cool climate, avoid heat and frost, like light, slightly resistant to shade; suitable for deep, fertile, well-drained soil.

The cultivation and management of hollyhock is relatively simple. When the seedlings grow 2 or 3 true leaves, they should be transplanted once and the row spacing should be enlarged. Watering should be done timely after transplanting. Topdressing should be applied 1 to 2 times before flowering combined with weeding by ploughing and weeding, and phosphorus and potassium fertilizer is better. After one transplanting, the sowing seedlings can be planted in November. During the seedling growth period, 2 Mel liquid fertilizer was applied for 3 times, mainly nitrogen fertilizer.

At the same time, often loosen the soil, weeding, in order to facilitate the growth of plants. When the flower bud was formed in the axil of hollyhock leaf, the phosphorus and potassium fertilizer was applied once. In order to prolong the flowering period, sufficient moisture should be maintained. Cut off the aboveground part in time after flowering, and new buds can sprout. When potted, it should be potted in early spring and keep the single plant to blossom.

As hollyhock seeds are easy to scatter after maturity, they should be harvested in time. After planting 3Mel for 4 years, the plant was easy to senescence. Therefore, it should be updated in time. In addition, hollyhock is easy to cross, in order to maintain the purity of varieties, different varieties should keep a certain distance. Hollyhocks are vulnerable to leaf rollers, aphids and red spiders, and old plants and dry weather are prone to rust, which should be prevented and controlled in time.

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. Key points of maintenance and management of flowers in autumn

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.

(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.
