What are the characteristics of cacti?
Main content introduction: What are the characteristics of cacti and the related information about understanding the basic knowledge of cacti in the aspect of green plants. Let's take a look together.
Mentioning cacti, everyone may have the feeling of spines in their印象. In fact, there is a kind of cactus that is not afraid of cold and is also freeze-resistant. Editor Lao Li's impression when he was young in the 1980s and 1990s was that the economy was not developed, and most of the small yards in his hometown were not brick walls but earthen walls. Cacti were planted on top of these earthen walls for theft prevention. Now, in editor Lao Li's hometown, earthen walls and cacti can no longer be seen. This kind of cactus has many hard spines, can bloom and bear fruit, and only has these memories.
So let's learn about cacti together today!
Cacti belong to the succulents. After years of cultivation, there are many varieties of cacti. According to incomplete statistics, there are currently thousands of species of cacti in the world. Cacti originally belong to desert plants and are very drought-resistant. Because of their high ornamental value, cacti are loved by the masses. However, one should be cautious when raising cacti, especially if there are children in the family, to avoid hurting them.
Cacti are easy to cultivate, but for beginners, they may be drowned. Cacti are very drought-resistant and do not need to be watered frequently. Beginners always like to water them for no reason, so there is a saying in the flower-raising world, "Beginners' flowers are drowned, while experienced gardeners' flowers are dried to death!" Do not water the cactus when the soil is not dry, as it can easily cause root rot. If you want the cactus to grow fast, keep it moist. Cactus roots have many fibrous roots and no obvious main roots, and the root system is not developed, so remember not to let water accumulate.
Cacti are light-loving plants. To adapt to desert life, they have evolved leaves into spines, so there is no need to worry about the cactus getting sunburned even in the highest summer temperatures. Pay attention to the potting soil temperature, as too high temperatures can damage the roots (usually, as long as the pot is not made of iron, the roots will not be hurt. For some small pots that become too hot to touch, pay attention to shading. This shading is not because the plant itself is afraid of the sun).
What are the characteristics of cacti?
Cacti are tolerant of poor soil, so they don't have high requirements for soil. They can grow normally in weakly acidic, weakly alkaline, or neutral soil. However, if you want the cactus to grow fast, try to match its habits. Compared to other plants, cacti tend to prefer slightly acidic soil, so you can add some acidifying substances (a few drops of vinegar or yogurt) when watering every month. Yogurt also has nutritional value, but considering the current global food shortage, it's best not to use yogurt. Watering can easily cause the soil compaction, so it's important to turn the soil regularly.
Although cacti can grow in poor soil, they grow very slowly, so fertilization is needed. preferably using organic fertilizers such as soybean cakes, cooked rice grains, and legumes. Fertilize once a month, and during the summer growth period, fertilize twice a month. Since the spines of cacti can hurt people, changing the soil requires attention to safety. The soil quality may become alkalized after two years, so it's advisable to change the soil every two years. When changing the soil, pay attention to pruning the roots, removing diseased, rotting, and weak roots.
Most cacti are not cold-resistant, so in winter, cacti should be moved indoors to overwinter, or they may easily freeze to death.
The above sharing about the characteristics of cacti and a comprehensive explanation of understanding the basic knowledge of cacti hope to help you.
