What is the minimum temperature for cactus hardiness

-12 degrees Celsius in Shandong, outdoor normal wintering.

The winter temperature of cactus is above 5, cactus likes sunshine, warmth, drought tolerance, is afraid of cold, waterlogging, acidic soil, suitable for growing in neutral, slightly alkaline soil, pH value. For this reason, the family cultivation of cactus should be placed on the windowsill with sunlight, and the sandy soil with good ice turning is preferable.

Cacti can promote plant growth in the sun, so they should be exposed to sunlight, but shade should be used in midsummer to prevent direct sunlight damage. For cacti that have been kept in an unventilated place for a long time;

In the dry and hot season, it is easy to be harmed by red spiders, showing an aging-like yellow-brown color, which affects its growth and ornamental value. In order to avoid the above phenomenon, it should be placed in a well-ventilated place.

The average cactus can safely overwinter as long as it has more than 5 degrees, and the ordinary cactus ball is best above 8 degrees: if it is a cactus ball or golden amber ball grafted with a measuring scale, it must be kept above 12 degrees, otherwise it may cause frost damage.

Above 5 degrees you can't die, that's my experience. When the temperature is low, it will not grow back, and it can only grow above 15 degrees.

Cactus winter, there is a big difference between the north and the south, there are some frost-free and frost-free areas in the south with a short frost period, the tip of the cactus can be wintered in the open air or moved indoors for a short time, pay attention to controlling the amount of water and preventing decay. The situation in the north is different, and many cactus lovers have the same experience: "The summer is good, but the cold winter is hard."

The winter temperature in the north is low, such as after the middle of the middle in North China, the growth of cacti slows down, and the palms should be moved indoors in the second half of the month. In winter, the room temperature is low, and the cacti are dormant. During the dormant period, the water can be retained, and the slight tide can be used, and the normal management will be carried out in the coming year.

If the indoor temperature can be kept around the degree at all times. Cacti can continue to grow. In East China and Central South China, the temperature in winter is higher than that in North China, but there is no heating equipment in ordinary households, in this case, cacti can only dormant for winter.

During the dormant period, it is still necessary to bask in the sun, if the indoor temperature can often be kept at about degrees, the cactus can still continue to grow, in East China and Central and South China, the temperature in winter is higher than that in North China, but the general family has no heating equipment, in this case, the cactus can only dormant for winter. During the dormant period, it is still necessary to bask in the sun, if it is placed in the shade, after the beginning of spring, because there is no light for a long time, it is easy to burn when suddenly exposed to strong light. The three-edged arrow lacks light in winter, and it is easy to rot in spring, and the temperature in the northeast is lower in winter, so the cactus should be moved indoors in the first half of the month, pay attention to heat preservation, and can only be moved out of the outdoors in the middle of the next year.

Cacti overwinter in the north and should not be fertilized, repotted or grafted.

Don't look at so many words, my heating is equal to almost no warmer than the outside, and it is not close to finding someone - - the temperature of my house is about 10 degrees I can't die in the house I don't know how much I don't know how much things inside are very good.

All cacti are not hardy, and most winters require a temperature of 5-15 degrees Celsius, and 0 degrees Celsius will definitely freeze to death, including the varieties you mentioned, which can tolerate 1-2 degrees Celsius, but 0 degrees Celsius will also freeze to death.

Cacti in the desert are okay again. The connotation can also be relied on.

All cacti are not hardy! As long as it is in a 0 degree environment, it will die in one to two days!

Sandalwood cacti can only tolerate temperatures as low as -8 degrees Celsius when completely dry.

Opuntia robusta is the most cold-tolerant species of succulents, and there are many that can tolerate low temperatures of 0 degrees Celsius, such as opuntia robusta, red hairy palm, Shura fan, Turen fan, Yenwu fan, Asahi fan, etc.

The Arctic Globe is also a very hardy species of cactus, and it is said to be able to tolerate temperatures as low as -22 degrees Celsius. But the most hardy is still Asahi, which can safely overwinter at temperatures as low as minus 48 degrees Celsius, making it the hardest succulent in the world.
