How do large potted pomegranate trees survive the winter outdoors in winter?

Hello, the outdoor wintering method of large potted pomegranate trees in winter can refer to the following aspects for management.

Large potted pomegranates.

1.Apply basal fertilizer in autumn. After the fruit is harvested, it is very important to apply the appropriate amount of basal fertilizer, and the autumn basal fertilizer should be applied before mid-October. It is mainly organic fertilizer for farmers, and the fertilizer can be mixed with an appropriate amount of phosphorus and potassium fertilizer for fertile leaves.

2.Shaping and trimming. Winter shearing is mainly sparse and long-run.

Thinning the excess rotating branches, crossing, parallel branches and sprouting branches, overly dense drooping branches, diseased and insect branches, dead branches, etc., so as to balance the tree potential and improve the ventilation and light transmission conditions; It is necessary to cultivate the fruiting branch group to fill the inner chamber and expand the fruiting area; For the branches with serious outward migration of the fruiting part, a suitable position should be selected for retraction; Secondly, a callus antiseptic film should be applied to the trimming mouth to prevent water evaporation and nutrient consumption.

3.Soil to protect against cold. The cold temperature in winter is easy to cause frost damage to the root neck of the pomegranate tree, before the soil freezes after winter shearing, the pomegranate root neck should be cultivated, the thickness is about 20 cm, or the root neck is piled into a small and large steamed bun-shaped mound, and the soil height is 40 60 cm.

It is required that the soil should be moist and loose, and the soil should be taken at a certain distance from the roots to prevent damage to the roots. At the same time, it is necessary to pay attention to the timely removal of the soil after the thaw in the spring of the next year to prevent the germination of a large number of root tillers.

4.Fill the frozen water. Filling the frozen water is conducive to the safe wintering of the tree and the prevention of drought in the spring of the second year, and can eliminate some overwintering pests. The time of pouring frozen water is before the soil is frozen, and it is advisable to irrigate thoroughly. After winter irrigation, the soil should be loosened in time to protect moisture to prevent soil compaction.

5.Autumn and winter pest control. The autumn and winter pests and diseases of pomegranate trees mainly include aphids, peach borers, red spiders, dry rot, brown spots, hemp skin diseases, etc.

The control measures taken for the above pests and diseases mainly include cutting off the diseased and insect fruits and dry diseased branches on the tree, scraping off the old warped bark, smearing the cracks in the trunk, removing the fallen leaves under the tree, thoroughly burying them or burning them in a concentrated manner, and carrying out the disinfection and sterilization of the whole park to protect the tree body and protect the safety of the tree body.

If you want to make the potted pomegranate tree survive the winter, you should keep enough light, the temperature is about 8, apply organic fertilizer or phosphorus and potassium fertilizer before winter, and pour a frozen water, cultivate soil at its root neck to prevent cold, and prune its large branches and small branches, and apply callus antiseptic film to the wound after cutting, and treat pests and diseases in time.

1. Control the light temperature.

The temperature is low in winter, how can potted pomegranate trees survive the winter so that they do not freeze to death, they should maintain sufficient light, potted pomegranates like light, and let them receive sunlight all day in winter. In terms of temperature, the most suitable temperature for potted pomegranate trees is about 8, not below zero and not above 20.

2. Control water and fertilizer.

If you want to make potted pomegranate trees survive the winter safely, you should fertilize it once before winter, you can choose organic fertilizer or phosphorus and potassium water-soluble fertilizer for fertile leaves. After fertilization, frozen water should be watered, pay attention to water frozen water when the soil is not frozen, and water thoroughly, but there can be no water accumulation in the pot.

3. Soil cultivation and cold protection.

In order to ensure that the potted pomegranate trees survive the winter, we must do a good job of cold protection. The root neck of potted pomegranate is prone to frostbite in winter, so a layer of soil should be buried in its root neck, and the soil layer should cover the root neck of the pomegranate tree, making it a large and small shape, and the soil used for soil cultivation should be loose and breathable.

4. Shaping and pruning.

In winter, potted pomegranate trees need to be pruned, and the distance between the branches should be kept at about 90 cm when pruning the large branches, and about 35 cm between the branches when pruning the small branches. When pruning, the branches should not overlap, and a layer of callus antiseptic film should be applied after pruning.

5. Prevention and control of pests and diseases.

In winter, it is also necessary to pay attention to the prevention and control of pests and diseases. When potted pomegranate trees are diseased, they should be sprayed with 150 times Bordeaux liquid or carbendazim solution once a week or so. When it has insect infestation, it can be sprayed with 20% imidothion 1000 times solution or 50% aphid emulsifiable concentrate 1000 times solution, and sprayed once every 8 days.

Potted pomegranate overwintering method:

In autumn, after the pomegranate leaves have fallen, it is watered thoroughly and placed in a leeward sunny place. Water thoroughly before the winter cold snap arrives. When the temperature is above 0 continuously, you can pour water once. In winter, the minimum temperature is not lower than -10 to safely overwinter; Below —10 Cover the pot with hay to keep warm.

In areas where the temperature is -15 in winter, it is necessary to overwinter indoors in winter. It can be poured thoroughly before entering the room, and placed in the room or cellar under 5. Watering can be done as appropriate according to the condition of the potting soil.

However, it should be noted that the temperature must not be higher than 5, otherwise the pomegranate will begin to sprout, consuming a lot of nutrients and reducing the number of flowers.

Larger pomegranates take up more space when moved indoors, and can be dug in the ground at twice the height of the pomegranate pot. Put the pot into a deep pit, fill it with soil and compact, and water it thoroughly. In areas where the temperature is lower than -15, the trunk of the tree must be wrapped with straw ropes and straw curtains to prevent frost damage.

In the spring of the following year, the flower pots will be dug out around Qingming.

Potted pomegranates are best kept at around 5 degrees Celsius in winter, as not having sufficient dormancy can affect flowering and fruiting the following year.

Pomegranate is a relatively cold-tolerant plant, the south of Beijing can spend the winter in the open air, the north of Beijing including Beijing is recommended indoor maintenance or greenhouse winter, to avoid frost damage, like Jiangsu and Zhejiang, potted plants can be placed outdoors for the winter is not related, the temperature in winter becomes lower it will fall leaves dormant, self-protection;

The second point to do is to top dressing, fertilization of pomegranates in autumn and winter can be matched with organic fertilizer with phosphorus and potassium fertilizer, organic fertilizer can be shallow buried on the surface of the pot soil, shallow burial once a month, which can help the plant to better recover its vitality, so that the plant can grow better, give phosphorus and potassium fertilizer in winter is to enhance the resistance of the plant, so that its branches can age rapidly, and can overwinter more safely, phosphorus and potassium fertilizer can be given once for half a month to 20 days, each time the ratio of 1:1000 directly irrigates the roots, you can choose Bika potassium dihydrogen phosphate, Pour it thoroughly and you're good to go;

If your pomegranate potted root system is full of pots, you can take advantage of the current pot to change the pot and change the pot to a larger one, and the new potting soil will also be more conducive to its growth;

Flower pomegranate is not the same pomegranate, small way of maintenance.

1. Insufficient hibernation pomegranate does not bloom or blooms poorly, potted pomegranates are generally placed indoors or balconies in winter, because there is heating or air conditioning indoors, the temperature is relatively high, and it is not suitable for pomegranate hibernation.

2. Potted pomegranates need -2 to -5 low temperature dormancy in winter, because potted plants cannot be lower than -10, otherwise they are prone to frost damage. If the temperature is higher than 5, it is not conducive to its full dormancy, and when the dormancy is not sufficient, the spring will grow poorly, and there will be no flowers or few flowers.

3. Do not enter the room too early in autumn and winter, and re-enter the room when the temperature drops to about -5 in the winter silver brother season, and put it in a low temperature environment not higher than 0-2.

4. Control watering, you can water once a month. In spring, when the outdoor temperature is around 0, you can go out of the room and put it in a sunny position, in case of "inverted spring cold", when the temperature drops sharply, it is necessary to protect it a little or temporarily move back indoors.

Potted pomegranate trees are hardy.

Potted pomegranate not only has the advantages of drought tolerance, heat resistance, light resistance, and thinness tolerance, but also has cold tolerance, in order to ensure that the plant is not frost damaged, the minimum outdoor temperature in winter should also be controlled above -18 °C.

Although potted pomegranates are hardy, they must also be moved indoors for maintenance in winter, because in winter it is easy to freeze the potting soil and freeze its roots to death.

Potted pomegranate trees survive the winter safely.

Environment: When potted pomegranates are maintained, they should maintain enough light, and they should be exposed to sunlight all day in winter, and the most suitable growth temperature is 8, and its roots are prone to frostbite in winter, so the roots of the pomegranate tree should be covered with a layer of soil.

Outdoor: Pomegranate bonsai can be placed outdoors in winter, but it needs to be insulated and cold, and it is also necessary to spray antifreeze before the leaves fall, spray polyvinyl alcohol or dimethylol cellulose after the leaves fall, and surround the tree with straw mats to build a shed to keep it warm.

North: Potted pomegranate trees can spend the winter in the north, but potted pomegranates in northern China generally cannot be kept outdoors, so when winter comes, it is necessary to enter the room in time.

How to raise potted pomegranate trees in winter.

1. Autumn base fertilizer: Pomegranates generally need to be fertilized in the autumn after the fruit is picked, and the best fertilization method is to mix the farmer's organic fertilizer with an appropriate amount of phosphorus and potassium fertilizer.

2. Pruning: In winter, pomegranate trees enter the dormant period, at this time, they are generally thinned and pruned, pruning cross, too dense, drooping branches and pest and disease branches. In addition, apply antiseptic film to the mouth of the pruned branches.

3. Inject frozen water: Inject frozen water to help the tree safely overwinter, prevent the spring drought of the second year, and eliminate some overwintering pests.

Control the temperature: Potted pomegranate trees, the indoor temperature is best at 3-5 degrees in winter. Water and Fertilizer Management:

Apply organic fertilizer once and water once before winter. Proper soil cultivation: In winter, pomegranate trees are planted with soil to control the temperature of the soil at the roots.

Pruning branches: Prune the more vigorous branches and the weaker branches that are diseased.

1. Control the temperature

Pomegranate trees are not cold-tolerant, and the indoor temperature in winter is best at 3-5 degrees, which can allow the pomegranate tree to enter the dormant period and accumulate nutrients for the growth of the next year.

2. Water and fertilizer management

Before winter, the pomegranate tree should be properly applied with organic fertilizer once, and then there is no need to fertilize again, and at the same time watering once, watering should not be excessive, to maintain the pomegranate tree's water demand throughout the winter, and watering can keep the soil temperature stable.

3. Proper soil cultivation

Pomegranate trees are more afraid of frost, especially the roots of the plant, so in winter, you need to cultivate a layer of soil for the pomegranate tree to control the temperature of the soil at the root of the plant, not too low, so as not to affect the dormancy of the pomegranate tree in winter, and wait until spring comes, and then clean up the soil layer.

4. Prune the branches

Before entering the winter, the pomegranate tree should be pruned properly, the branches that grow more luxuriantly, as well as the weak branches with disease, and at the same time, disinfectants and antifreeze agents should be used at the wounds after pruning to reduce nutrient consumption and allow the plants to survive the winter safely.
