What is the growing temperature for cacti?
Do you know this? The topic of the growing temperature for cacti is related to the cultivation of flowers. If there are any mistakes, please feel free to correct them!
What is the growing temperature for cacti?
Cacti thrive in high-temperature environments, with the optimal growth temperature ranging between 20 to 32℃. If the temperature is outside this range, the growth rate of cacti will slow down. Cacti can tolerate high temperatures, and usually, when the temperature exceeds 35 degrees, the growth of the plant will slow down. Most cacti can tolerate a minimum temperature of 5 degrees Celsius, and the cultivation environment temperature needs to be above 5 degrees to safely survive the winter.
Characteristics of cacti growth
Cacti are native to desert environments and prefer a high-temperature and dry growth climate. Overwatering can cause death, they prefer well-draining sandy soil, and they are sensitive to cold. Summer is the growing and flowering season for cacti.

Do cacti tolerate high temperatures?
Cacti can tolerate high temperatures but should not be exposed to high temperatures for extended periods, otherwise, they may turn black. Usually, when the temperature exceeds 35 degrees, the growth of the plant will slow down.
What is the minimum cold tolerance for cacti?
Most cacti can tolerate a minimum temperature of 5 degrees Celsius, and the cultivation environment temperature needs to be above 5 degrees to safely survive the winter. Some varieties can also tolerate temperatures below zero.
At what temperature can cacti be planted?
Generally, if the temperature of the cacti cultivation environment is between 20 to 25 degrees Celsius,播种 can be carried out, with a higher survival rate.
The growth process of cacti
The seeds of cacti will start to germinate after a few days. After some growth, you can see them develop small spines. As they continue to grow, they will form very small balls, and then the balls will grow larger, eventually developing into a healthy plant. The final stage is flowering and fruiting.
How to plant cacti
Potting soil selection: When planting cacti, it is best to choose loose and well-draining sandy soil. You can use ordinary black plastic pots for planting, and after disinfecting the soil, put it into the pot.
Seed treatment: First, wash the fruit flesh off the surface of the cacti seeds with clean water and let them air-dry. Then, prepare a solution of potassium permanganate in cool water and soak the seeds in it for about half an hour before drying them.
Planting: Sow the seeds on the surface of the soil without covering them. Cover the pot with a layer of plastic film and make a few small holes in the film with a toothpick to ensure ventilation. Place the pot in a wind-protected and diffused light environment and wait for germination.
