Every winter, the anthurium freezes to death, what to do

Anthurium, also known as flower candle, needs to control the temperature and humidity in winter, and watering also needs to be properly watered.

1. Temperature. Anthurium is a tropical plant, and the minimum temperature in winter should not be lower than 10, if it is lower than this temperature, it may freeze to death. Growth stops at 14 and the optimal growth temperature is 18-28.

In winter, place anthuriums in a place where sunlight can be used, ensure sufficient morning and evening light, and keep the indoor temperature above 15.

2. Humidity. Anthurium growth requires high air humidity, not less than 50%, high temperature and high humidity will be more conducive to the growth of anthurium. In winter, even if the indoor temperature is high, it is not advisable to cool down and moisturize too much, because the leaves of the plant are too wet at night, which will reduce the cold resistance and is prone to frost damage.

In winter, it does not need to have too much moisture at a higher room temperature, and if its leaves are too moist in the evening, it will weaken its ability to resist the cold, and it is more susceptible to frostbite, which is not good for it to survive the winter.

3. Moisture. In winter, watering should be properly controlled to dry out the soil, which may freeze the root system due to freezing. When the potting soil is slightly dry, spray the leaves 2-3 times a week, and if the room temperature is low at night, you can use plastic film to cover the whole plant to keep warm and moisturize.

Winter watering should not be too much, the water temperature of winter watering and spraying flowers should be the same as room temperature, do not use tap water directly, you can put tap water for a period of time or add a little hot water.

Society Life Flower Gardening Breeding Anthurium Frostbite in winter is very distressing, don't throw it away, the flower master will teach you a trick to bring it back to life!

Anthurium flowers are frozen, and the maintenance temperature should be increased appropriately.

Anthurium and hand flower maintenance method:

1. Maintain relatively high air humidity, which is the key to indoor maintenance, and must take measures to improve the air humidity of the environment where the anthurium is placed, and can use foliar spray (pay attention to ensure that the foliar surface is devoid of water at night) and other methods.

2. Sufficient fertilizer and water. Spring and autumn generally water fertilizer once every 3 days, such as high temperature, depending on the substrate in the pot dry and wet can be watered once in 2-3 days. In summer, it can be watered once every 2 days, and when the temperature is high, it can be watered once, and in winter, it is generally watered once every 5-7 days.

Special fertilizer. 3. It should be watered thoroughly at one time, keep the substrate moist frequently, promote its early emergence and draw more new roots, and pay attention to the dryness and humidity of the pot substrate; Plants in the medium and large seedling stage grow fast, require more water, and water must be sufficient; During the flowering period, watering should be appropriately reduced, and phosphorus and potassium fertilizers should be increased to promote flowering. Be sure to alternate wet and dry during the watering process.

In winter, anthurium will freeze to death, and when the temperature is below 0, anthurium may freeze to death. In winter, when the temperature drops, anthuriums need to be kept indoors to keep warm for the winter. Cultured anthurium needs to be placed in semi-shade and exposed to scattered light.

In terms of watering, it is necessary to water according to the principle of seeing dry and wet.

Anthurium will freeze to death in winter, and anthurium will stop growing when the temperature is below 15, frostbite when the temperature is below 10, and anthurium may freeze to death when the temperature is below 0. When the temperature drops in winter, it is necessary to keep the anthurium indoors in time.

To keep anthurium indoors, it is necessary to ensure that the indoor temperature is above 15 in order for the anthurium to survive the winter safely. In winter, when the temperature drops and the water evaporates slowly, it is necessary to reduce the frequency of watering to avoid water accumulation in the root system, which can lead to the freezing of anthurium.

Anthurium cultivation method.

To cultivate anthurium, it is necessary to prepare loose and fertile, well-drained and permeable soil, and ensure that the ambient temperature is 15 25. Anthurium loves light, but is afraid of strong light, so it needs to be placed in semi-shade to receive scattered light. In spring, autumn and winter, it can accept scattered light, and the summer is hot, so proper shade is needed.

Anthurium has a high demand for water, but is afraid of stagnant water, so it needs to be watered according to the principle of seeing dry and wet. This can not only ensure that the anthurium has sufficient water, but also avoid the root soil from waterlogging, which will lead to root rot.

Anthurium freezes to death in winter and germinates in spring, and as long as the root system of the plant is not completely frozen to death, new shoots will grow on the branches when the temperature rises in spring. To promote the germination of anthurium, it is necessary to prune the frostbitten, rotten part of the plant, soak it in a diluted disinfectant for 20 to 30 minutes, and then plant.

When Anthurium grows in winter, if only part of the surface of the soil withers and dies, when the temperature rises in spring, the plant can resume normal growth and new shoots will grow on the branches. If the root system of Anthurium is also frostbitten and necrotic, no new shoots will grow in the spring of the following year.

Anthurium has a weak ability to tolerate cold, and when the temperature is 5 degrees Celsius, it will enter a dormant state, and the state of vital activity will be weakened, and when the temperature is lower than zero degrees Celsius, the plant will have frostbite and freeze to death. Therefore, when cultivating anthurium in winter, it is suitable to maintain it in a warm and ventilated room.

In order to promote the germination of anthurium, it is necessary to cut off the stems and leaves that are frostbitten and rotten in winter, dig the root system out of the soil, check the growth, avoid the occurrence of root rot, apply chlorothalonil or carbendazim solution to the wound, place it in a cool and ventilated environment to dry for later use, and wait until the wound heals before planting.

Before replanting the anthurium, the plants need to be soaked in a disinfectant solution for a controlled period of 20-30 minutes. The treated plants are placed vertically in the potting soil to ensure that the soil is loose, breathable and has a high nutrient content, and is placed in an environment with a temperature of about 12 degrees Celsius.

Anthurium is very afraid of cold, can not let the temperature lower than 14, need to maintain the temperature at about 15 20, when the anthurium frostbite branches and leaves dry and yellow, need to cut them all, and need to wait for the soil to gradually dry up when the appropriate amount of watering, but also in time to add a nitrogen and phosphorus fertilizer, and wipe the leaves with beer.

Anthurium is not cold-tolerant, if the temperature is lower than 14, it is easy to frostbite the plant, what if the anthurium is frostbitten, first of all, you need to immediately raise the winter temperature, you need to maintain the temperature at about 15 20, so as to stop the harm of anthurium frostbite, so that it gradually recovers its vitality.

When Anthurium frostbite, some branches and leaves will dry up and turn yellow, so in addition to controlling the temperature, you can also cut off the dry and yellow part of Anthurium, which can not only restore its ornamental value, but also make Anthurium better get nutrients in the soil, so that Anthurium can grow better in winter.

Generally, anthurium frostbite should also do a good job of water control and fertilization, do not water it frequently when frostbite, you need to wait for the soil to dry up, and then loosen the soil, spray water on the soil in an appropriate amount, and add nitrogen and phosphorus fertilizer in time to reduce the harm of anthurium frostbite.

Beer is rich in minerals, which have a lot of anthurium ingredients, whenever its temperature is too low to frostbite, we can also use beer to gently rub the leaves of the anthurium, once every other week, the leaves of the anthurium can be restored to their original color, so that it gradually recovers its vitality.

Anthurium is very afraid of cold, can not let the temperature lower than 14, to keep 15 20 or so, when the anthurium frostbite branches and leaves dry and yellow, to cut off all the keys to it, to wait for the soil to gradually dry out before watering, but also to increase nitrogen and phosphorus fertilizer in time, with beer to wipe the leaves.

Anthurium frostbite raises temperatures.

Anthurium is not cold-tolerant, if the temperature is lower than 14, it is easy to frostbite the plant, what to do if the anthurium is frostbitten, first of all, we must immediately increase the winter temperature, keep it about 15 20, so as to stop the frostbite of the anthurium, so that it can gradually recover its vitality.

Anthurium frostbite prunes off dead branches.

When the anthurium appears frostbite, the branches and leaves will dry and yellow, so in addition to controlling the temperature, it is also necessary to cut off the yellow part of the anthurium's hair, so that it can not only be held to restore its ornamental value, but also make the anthurium better obtain nutrients and grow better in winter.

Anthurium frostbite controls water and increases fattening.

If the anthurium has frostbite, it is recommended to pay attention to water control and fertilization, do not water it often when it is frostbitten, wait for the soil to dry out, and then spray it into the soil, and spray some nitrogen and phosphorus fertilizer on the soil in an appropriate amount to reduce the degree of frostbite of the anthurium.

All you need to do is raise the temperature around you. Then we cut off some of the damaged leaves, and we have to add some fertilizer to it, taking care not to add too much water to it. In winter, you can use banana peels to wipe it from time to time, and you should also use warm water for watering in the south, so that it does not freeze badly.

When the temperature is lower than 15, it is necessary to reduce watering, wait until it is dry, and use about 20 degrees of water for each watering, so that the sub-plants will not be injured by sudden cold water.

Because it grows more slowly at this time, you can consider applying fertilizer to it, using urea or flowers. Our recommendation is to do it once every six months, and it is recommended to do it at noon.

If the temperature here is even lower, below 10 degrees, keep it warm, cover it with a plastic bag at night to keep it warm, and move it to a place where it can be exposed to light during the day, where it can receive light and provide its own nutrients.

Caused by mismanagement.

Cultivation management: 1Temperature and light.

Anthurium is more sensitive to temperature, suitable growth temperature 14-35, optimal temperature 19-25, day and night temperature difference 3-6, that is, the best daytime 21-25, night about 19, at such a temperature, is conducive to the absorption and accumulation of nutrients in Anthurium, is extremely beneficial to growth and flowering. If it is less than 13 for a long time, the plant will not die, but it is difficult to recover growth for a long time; When the temperature is higher than 35 and the light is sufficient, the leaf surface is prone to burns, because the damaged leaves will not be reversed, which affects the overall quality of anthurium and creates difficulties for the next step of maintenance.

Under the conditions of intensive production, automatic temperature control equipment is often used for heating, and in winter, boilers are used for heating or installation of warm air heating equipment, such as oil heating machines, double-layer plastic sheets, cold-proof cloths, mats, straw, etc. Cooling often uses water curtain - fan cooling system, which is also a commonly used scheme for cooling in northern China, or water mist cooling and humidification equipment, you can also open the top window and side window of the greenhouse, and roll up the plastic sheet on the side of the plastic shed. Home maintenance, such as living in a bungalow, can be placed on the sunny side in winter, can be placed in the curtains at night, or close to the heat source, placed in the room in the shade of the window sill in summer, and pay attention to ventilation, can also be placed in the hall, or moved out of the day during the day, placed in a cool place.

Anthurium is a shade-tolerant plant and should not be exposed to direct sunlight, but do not think that Anthurium is a shade-tolerant flower and does not need light. It has been observed that when the light is increased by 1%, the flower production will also increase by 1%, but this is within the appropriate light intensity range of the anthurium. The most suitable light intensity range is 10,000-20,000 lux, mainly depending on the different growth conditions of different varieties and different growth periods, and in any case ensure that the light does not exceed 25,000-30,000 lux for a long time.

Under the conditions of intensive production, the shade often adopts a double-layer shade net, a layer of 40% fixed shade net is used outside the greenhouse, and a movable 60% shade net is erected in the greenhouse, and the light intensity is adjusted freely every day.

Home maintenance can be placed on the shady side of the room or in the hall with scattered light in summer, or in a place where direct sunlight is not visible outside, such as under the shade of trees, flowers or in the shade. In winter it should be placed on the sunny side of the room.

2.Moisture and humidity.

3.Cultivation substrates and fertilizers.

5. Pest control.

1.Potted anthurium sometimes has premature flower senescence, deformity, adhesion, cracks, vitrification and blue spots, which are mostly physiological diseases caused by improper management of fertilization, potting soil and air humidity or variety. The prevention method is to improve cultivation management, reasonable fertilization, and proper ventilation.

2.The main pests and diseases of potted anthurium are bacterial wilt, leaf spot, root rot, cylindrium, bispora spp., nematodes, red spiders, aphids, lepidopteran pests, whiteflies, scale insects, snails, etc.

The suitable day temperature for the growth of Anthurium is 26 32 and the night temperature is 21 32. The maximum temperature that can be tolerated is 35 and the low temperature that can be tolerated is 14. In layman's terms, it's not good to be cold, and it's not good to be hot. You see if it's because the temperature isn't right.

Most of them are frozen to death or watered, and the temperature needs to be above 15 degrees.
