Excuse me? The cactus that I only rushed down in the past two days, will it freeze to death if it is

Many flower friends may worry about whether the plants at home will be frozen to death in winter, and recently some flower friends have asked the florist uncle whether the cactus will be frozen to death in winter. The uncle told everyone that the cactus will not be frozen to death as long as the temperature is not lower than zero, because the cactus is a succulent and succulent plant, and in the low temperature below zero, the cactus cells will freeze along with the juice in the body, and the cell wall will freeze and crack and freeze ripe. Therefore, the method of raising cacti in winter is as follows:

1. Less watering: Cactus is a tropical plant that grows in drought and high temperature, and should not be watered too much, otherwise it will cause the cactus rhizome to rot. After the cactus enters the winter, it should be stopped watering and the potting soil should be kept dry to promote its dormancy.

If improper watering is carried out in winter, breaking their dormancy and restoring their physiological activity, the cold tolerance of the plants will be reduced, and they will be susceptible to frost rot.

2. Spend more sunlight: Cactus is a tropical plant, and the original growth environment is strong in sunlight, so if you want it to grow well, you should put it in the sun every day, and you are not afraid of the strong light at noon.

3. Flower pots should be aerated: the bottom of some pots is not ventilated, and if the pots are not ventilated, water will be generated. If there is stagnant water below 0°C, it will freeze, which will corrode the roots of the cactus, causing the plant to freeze and die.

4. Keep indoor ventilation: The origin of cacti is generally an empty desert with good ventilation. Therefore, try to keep the room ventilated during the breeding process, and often open the windows for ventilation.

Of course, the cacti that rushed down in the past two days will not be frozen to death at minus 35 degrees, because cacti are only suitable for areas with high temperatures, not for low temperatures.

Most cactus balls (palms) need minus 5 degrees to safely survive the winter, and some cacti (palms) can withstand low temperatures of minus a few degrees or even minus ten degrees, and this kind of low-temperature resistant cactus balls do not go through low temperatures, and the flower buds are not well differentiated in the coming year, and they are not easy to flower.

Due to the fleshy nature of the cactus (palm), once it encounters low temperature frost damage, it is very perishable, and develops from one point to the whole decay. Therefore, once it is found that the immortal human plant has suffered frost damage, it is necessary to cut off (dig up) the frost damage part in time, and do not hesitate to cut until the tissue is intact.

The frost-damaged parts are generally brownish-black, and the intact parts are generally emerald green or slightly white. Then apply the wound with plant ash or carbendazim powder, without the above materials, you can also dry the wound with a hair dryer for only one purpose - to prevent the wound from rotting.

If the root rot is removed, it must be dried for 2 weeks or even longer, until the wound is completely healed, and then the roots are planted in the tidal soil, and the roots can be maintained normally after the root system grows.

Growing cactus succulents without a greenhouse is possible in the wild, even in very harsh climates, very rainy, wet autumns and cold winters! It is also possible to breed at minus 20 degrees. .

Although the cactus plants that survive in the wild are not very beautiful!

Below I list the cacti that can laugh at minus 20 degrees:

Escobaria Escobaria Missouuriensis is native to the central and northern United States, and this species is fine at minus 25 degrees Celsius, and it seems that rain and cold winters will not cause obstacles to outdoor farming.

Escobaria Arctic Globe Escobaria Vivipara Habitat from the United States Southeast Canada, often covered with snow in winter, minus 20 degrees Celsius is completely fine!

Escobaria Sumeru Escobaria Sneedii This cactus is also very hardy, but it is important to note that the soil is not free of organic matter.

There are also species of the genus Escobaria that can overwinter outdoors at minus 20 degrees Celsius, such as Escobaria organensis, Escobaria Robbinsorum, and Escobaria Tuberculosa.

The blue and white shrimp of the genus Echinocereus viridiflorus blooms beautifully and can also overwinter in most parts of China. There are many varieties of Echinocereus coccineus and there are slight changes depending on the place of origin, but there are records abroad that some varieties can overwinter at -20 degrees, but there is no problem at minus 10 degrees.

Opuntia is a large genus that grows in the United States, Canada, Argentina, and most species can overwinter outdoors. It can also be safe and sound in temperatures of -60 degrees. The representative species is the fig fan opuntia ficus-indica.

The classic pediocactus is safe to overwinter at -20 degrees. For example, Pediocactus simpsonii can overwinter at -25 degrees, all genera Pediocactus can overwinter at temperatures of -10 degrees or even lower, and Maihuenia Poeppigii can completely overwinter outdoors, can tolerate -10-20 degrees of severe cold, common outdoor farming in the United Kingdom and central Europe, this thing is not delicate, phosphorus and potassium fertilizers can be used for breeding, and organic matter can be used as breeding soil. Maintain direct sunlight for at least a few hours a day.

Answer: Cactus is one of the most cold-tolerant plants in the world, mainly because of the comprehensive results of its physiological structure and appearance, mainly the following points: 1. The leaves mutate into slender thorns or white hairs to reduce the transpiration of water, weaken the harm of strong sunlight to the plant, and can also make moisture continue to accumulate and condense into water droplets, which drip to the ground and be absorbed by the shallowly distributed root system; 2. The stalk is thick, thick and juicy, with well-developed parenchyma tissue cells, with ribs, so that its body can expand freely, and it can expand rapidly when there is more water in the body, and can shrink inward when it is drought and lack of water, which not only protects the plant epidermis, but also has the effect of heat dissipation and cooling. 3. The epidermis of the stem has a thick and hard wax as a protective layer, or has dense fluff to protect it from strong light and reduce water evaporation.

4. The stomata are open at night and closed during the day to reduce water dispersion loss. 5. The stalk is green, which can replace the photosynthesis of leaves and make food. 6. There are many root branches and a huge system, and many new roots will grow in the topsoil when it rains, absorbing a large amount of water.

Its large roots are protected by a thick wooden cork and can live on scorching sand without dying.

Hope it helps.

The lowest cold-tolerant temperature of cactus is about 0, and it will not freeze to death above zero, which is worse than that of wanton sensitivity. When the ambient temperature is more than 10 degrees below zero, most varieties of cacti will freeze to death. Only a few species of cacti may survive, but if the soil is frozen, its roots will not be able to breathe and laugh, and when the temperature rises, it will easily turn into water and die.

Cactus balls will freeze to death at minus a few degrees.

Generally, if the temperature of the split branch is lower than 10 degrees, the cactus can be watered or fertilizedAt this point, dormancy or hibernation begins。By the following spring, when the temperature was above 15 degrees, the recovery began.

So,Cacti are not frost resistantGenerally, the minimum temperature in winter can only withstand about 5. To survive the winter safely, the minimum temperature needs to be controlled at 5-10. If you survive below 0 for a long time, the cactus will freeze to death

Even the most frost-resistant cactus,In winter, the temperature is below minus 10 degrees, the whole cactus will be frozen. When the temperature rises, the cactus will turn into water and die, and if you are lucky, the root system inside the flower soil will not freeze to death until the next spring, and new side buds will grow.

The temperature should be high

The cactus is known to be a desert plant. So if we want to raise it well, we must raise the temperature. Generally, at sub-zero levels, its fleshy plants will suffer from frost damage, resulting in softness.

So if you want it to grow normally in the winterBe sure to adjust the temperature to more than 10 degrees Celsius, never too low。You can usually keep it indoors for maintenance, and don't put it outdoors to be blown by the cold wind.

Water control

The cactus requires very little water, and it usually does not need to be watered too much in the spring and summer, thenIn winter, there is no need to water too much, otherwise it is easy to have problems

For example, in the current time period, everyone should try to control the water and cut off the water for it, otherwise it is easy to rot. If you want to control the water, you can usually water it once before winter comes.

If your cactus is shriveled, it's not all about lack of watering. Generally speaking, too little moisture will not cause severe softness in winter.

More light

This last point is also very important, we all know when it comes to maintaining succulentsWill put it in a very sunny place, the same goes for cacti.

In this way, it is able to absorb enough energy as it grows to convert this energy into nutrients and store it in the plant for a healthy winter.
