Can cacti be grown in river sand?
Do you know these? Can cacti be grown in river sand and detailed introduction of the characteristics of green plants and flowers. Next, the editor of this site will introduce to you.
Recently, the rainfall in Shandong region seems endless, on and off for a week. There are many cacti in the courtyard of my hometown. Cacti are most suitable for outdoor maintenance. Too much rain has caused some of the cacti to burst. The reason why cacti burst is due to excessive dryness in the early stage.
The cacti in my hometown are basically unmanaged, planted in flower pots and placed in the courtyard. They rely on nature for the later stage. It is very suitable to grow cacti in the northern region, where they can be placed in the courtyard in spring, summer, and autumn without shading or rain protection, completely exposed to the elements without any problems, and no need for artificial watering during this period.
The biggest feature of cacti is their drought resistance. In the northern region, it hardly rains in spring, and the climate is very dry. It's not until the end of summer, approaching autumn, that there is a lot of rainfall. In the first 3 to 4 months, cacti basically absorb no water, only after the rainfall increases in autumn can they absorb water.
Due to the long absence of water absorption, the cacti tightly wrap inward to reduce water evaporation. When the rainy season comes and there is prolonged rainfall, the roots of the cacti absorb a lot of water and nutrients. The absorbed water is stored inside the cacti, causing them to slowly expand.
Can cacti be grown in river sand?
Due to the long duration of rain, the roots of the cacti continuously absorb water, causing too much water to be stored inside the cacti, leading to bursts. This indicates that they are in good condition and there's no need to worry. The wounds from the bursts will slowly heal naturally, or many daughter cacti will sprout from the burst parts.
All the cacti in my hometown are grown in river sand. There is a small stream in front of my house. During heavy storms, the entire river is filled with river sand, which is swept clean without any dust particles. The river sand accumulates, and after every rain, I would collect some large-particle river sand with a shovel to grow cacti.
River sand can be said to be the best substrate for growing cacti. The cacti rooted very quickly in it. The daughter cacti broken off from the mother cacti can take root in about two weeks when buried in river sand. Clean river sand is rich in calcium and more practical to use than nutrient-rich soil, and there's no need to worry about root rot.
