How to wait for calamus in winter, and whether calamus will freeze to death in winter

1. Don't be frostbitten. The suitable growth temperature of calamus is 20-25, and the temperature will stop growing when the temperature is lower than 10. Although calamus has a certain ability to adapt to the cold, it can still get frostbite or even freeze to death when the temperature drops to about 0.

Therefore, in the area of snow and ice in winter, the iris must be moved into the indoor maintenance, if the indoor heating is not provided, there will be indoor freezing, it is necessary to pay attention to the work of keeping warm.

2. Do not leave it in a cool place for a long time. Most of the friends who maintain iris indoors place them on desks, coffee tables, cutting boards and other shady places that do not see sunlight. Although calamus is a plant that likes coolness, it should not be out of the sun for a long time.

It should always be placed indoors in a sunny place to bask in the sun, and at noon on a relatively warm sunny day, you can also put the calamus outdoors to receive direct sunlight.

3. Don't make the pot too wet for a long time. Although calamus does not like a dry environment, due to the low temperature in winter, slow evaporation, and poor indoor air circulation, if you water too much, it is easy to make the potting soil too wet for a long time, which will cause the calamus root system to breathe difficult, and in severe cases, it will rot the roots. Therefore, the watering of the iris in winter should be properly controlled, and the surface of the potting soil should be found to be dry and then watered, and the water flowing from the bottom of the pot should be poured out in time when watering, and the tray can not store water, otherwise it will affect the breathing of the roots.

Fourth, don't prune too much. In winter, the old leaves of calamus are easy to turn yellow and dry tips, for the sake of beauty, some friends like to cut off the whole leaf from the root as soon as they find yellow leaves and dry tips. In fact, it is unreasonable to re-cut in winter, because winter is the dormant period of calamus, and there will be no new leaves to grow.

It is preferable to find that the dry tip of the yellow leaf is not in a hurry to cut off the whole leaf, but only cut off the dry part, so as not to harm the root of the calamus.

Calamus usually grows at the water's edge, the favorite growth temperature is 20-25, when the temperature is lower than 10 will stop growing, it is difficult to tolerate cold, not tolerant to drought, even in winter maintenance should also pay attention to timely replenishment of water, appropriate replenishment of light, the following is a specific introduction to the maintenance requirements of calamus in winter.

1. Move indoors.

Calamus is not weak in its adaptability to the cold, but not every place can adapt to winter, in the north, even if its cold resistance is good, after all, the environment is too cold, so it must be kept indoors. That way, the iris won't get frostbitten. to be safe.

of the whole winter.

2. Prune dead leaves.

The old leaves of calamus can easily start to turn yellow in winter, and if not pruned in time, it can easily cause the leaves to rot. At this time, you should not be in a hurry, do not pluck the leaves with your hands, but cut off the leaves, so that the roots of the calamus will not be harmed. It also does not affect the growth of the surrounding leaves.

3. Illumination. This is a point you need to know that even if you love cool plants, you can't go without light for a long time, and in slightly warmer weather, you can also put calamus outside to absorb the sun. If there is no suitable weather in time, it should be placed in a brighter place at the right time.

Fourth, moisture. Calamus does not like a dry environment, a little found that the soil is a little dry, it is necessary to water the appropriate amount, at this time the pot can not store water, otherwise the roots can not breathe well.

Look at what kind of calamus, if it is a water calamus, it is not cold-tolerant, the leaves will wither in winter, and new seedlings will be born in spring; If it is a calamus, it can withstand a low temperature of about -10 degrees, that is, as long as the temperature is not particularly low in winter, the calamus is evergreen, if it is too low, it is best to move indoors...

The following are water calamus.

Calamus will freeze to death in winter, when the temperature is below 10 degrees Celsius, the leaves and roots of the plant will be frostbitten, when the temperature is below 0 degrees Celsius, the plant is easy to freeze to death. In winter, when raising calamus, it needs to be moved to a room with a temperature of about 15 degrees Celsius for cultivation to ensure a ventilated and sunny growing environment, and then water when the soil is dry.

When the calamus grows in an environment with a temperature of 10 degrees Celsius in winter, the leaves and roots are prone to frostbite, and the growth rate of the plant will slow down, and when it grows in an environment with a temperature of 0 degrees Celsius, the plant will be frostbitten, resulting in stagnation of life activities, unable to survive the winter smoothly, and the phenomenon of death occurs.

How to care for iris in winter.

In winter, when the iris grows in the environment of 10 degrees Celsius, it needs to be moved to the indoor culture at a temperature of 15 degrees Celsius, and can be placed on a sunny balcony or window during the day, and must not be placed in the place where the empty bridge is mixed with the radiator, dry air and too high temperature are not conducive to the growth of plants.

When the iris is cultivated indoors in winter, when the soil on the surface begins to dry out, it needs to be watered, and the temperature of watering should be controlled at about 50 degrees Celsius to ensure that the water can flow out of the bottom of the pot to achieve the purpose of replenishing the water content in the soil. There is no need to apply fertilizer when rolling the hand to avoid the occurrence of fertilizer damage, which will lead to root rot.

When the growth rate of calamus slows down in winter, or stops completely, a small amount of nitrogen and phosphorus fertilizer can be applied to rot and ferment to speed up the growth rate of the plant. Prune the yellowing, wilting, pests and diseases on the plant in time to avoid the bacteria from infecting the whole plant, affecting the normal growth and development, and also reducing the loss of nutrients.

The minimum outdoor temperature that calamus can grow in winter is 5, when the outdoor temperature is lower than 5, it needs to be moved to a temperature above 10, sunny, ventilated and ventilated indoors for cultivation, regularly pruning wilted, yellowing, pests and diseases, rotten branches and leaves, watering every 2 3 days, be sure to control the amount of watering.

The minimum temperature at which an iris can survive the winter is 5

When the outdoor temperature ruler is lower than 5, the plant needs to be cultivated indoors, otherwise it will frostbite the roots and leaves of the plant and the plant, weaken the ability of the root system to absorb soil nutrients, and cannot ensure that the plant can survive the winter normally.

Methods of maintenance of calamus for winter.

Calamus in the winter, need to be moved to the temperature above 10, sunny, ventilated room for cultivation, must not be placed next to the radiator or air conditioner, which will speed up the transpiration of the plant itself, resulting in a serious lack of water in the leaves of the plant, wilting, yellowing, slowing down the growth rate.

When the branches and leaves are found to be wilted, yellow, drooping, pests and diseases, they must be cut off in time to prevent infection of the entire plant, resulting in plant rot and necrosis. After the pruning is completed, carbendazim needs to be applied to the incision to play the role of sterilization and disinfection.

Calamus in the winter, can not be placed in a closed room for breeding, so that the air is not enough circulation, the content of carbon dioxide gas is higher, will inhibit the photosynthesis of the plant, reduce the content of organic matter and glucose formed by the plant itself, can open the window for ventilation 2 3 times a week, conducive to plant growth.

1.After gladiolus flowering, the leaves will gradually wither, and the withered leaves can be pruned off, and then the soil can be loosened to remove the bulbs.

2.If it is in the southern region, the conditions for vernalization of the bulbs can be met, and the bulbs can not be removed.

3.After removal, shake off the soil attached to the bulbs and place them in a cool place to dry.

4.In winter, bulbs are stored in the shade, either in a shaded room or in the freezer compartment of the refrigerator.
