Cactus Growing Conditions and Characteristics

Here are detailed introductions to the growing conditions and characteristics of cacti for netizens, some great gardening tips that are worth collecting!

Cactus Growing Conditions and Characteristics

Cacti mainly grow in desert areas, native to the east coast of Mexico, the southern and southeastern coastal areas of the United States, the West Indies, the Bermuda Islands, and the northern part of South America. Cacti have varying requirements for their growing environment, with most species only starting to grow when spring temperatures rise to 18-20°C. The optimal growing temperature for cacti is 20 degrees, humidity at 30%, and they thrive best in fertile soil.

Cactus Growing Conditions and Requirements

In China, cacti were introduced at the end of the Ming Dynasty and are commonly cultivated in the southern coastal areas. They are wild in the southern parts of Guangdong, Guangxi, and the coastal areas of Hainan. Cacti enjoy sunlight, warmth, and drought resistance, but they dislike cold, waterlogging, and acidic soil.

Cactus Growing Temperature

The suitable temperature for cactus growth is generally between 20-30°C, not lower than 5°C in winter. The room temperature should be maintained above 20°C during the day and not lower than 5°C at night. Low temperatures can easily cause root rot, and a temperature above 6°C is sufficient for safe overwintering.

Cactus Growing Humidity

The suitable humidity for cactus growth is 30%. For watering issues, less water should be given in spring, a moderate amount during the flowering period, and watered every 2-3 days in summer, following the principle of "better dry than wet". In autumn, water when the soil is dry and loosen the soil after watering.

Cactus Growing Soil

Cacti prefer fertile, well-draining sandy loam soil. For pot cultivation, a mixture of 3 parts each of decomposed leaf soil, garden soil, and coarse sand can be used, with the addition of炉灰 (炉灰 meaning "ash from a stove") or crushed eggshells, or a special growing soil available in the market (C-S).

Cactus Growth Cycle and Process

In greenhouses, cacti generally bloom from April to June, with May being the peak blooming period. Most cacti grow for 3-4 years, and when the caudex reaches 3-4 centimeters or more, they bloom annually.

The growth process of cacti is mainly divided into two stages. The young cacti are bright green with dense spines, usually white in color. The mature caudex is larger, with more scattered spines, usually blooming at the top and bearing fruit on the spines.

The above is [] all about the growing conditions and characteristics of cacti for your comprehensive understanding and reference!
