In recent years, interior decoration has increasingly focused on the use of green plants. As a succulent, the cactus is popular for its high oxygen absorption rate and drought resistance. However, growing cacti also requires certain skills and precautions. This article will introduce the cultivation methods and precautions for cacti.
I. Soil Selection
Choose soil that is well-aerated, well-draining, and fertile, such as peat soil or leaf mold. Avoid using overly fertile soil, as it can easily lead to root rot.
II. Pot Selection
Choose a pot that is well-aerated and of an appropriate size. If the pot is too large, it will be difficult to balance moisture, which can easily cause root rot. At the same time, some gravel or sand should be placed at the bottom of the pot to ensure good drainage.
III. Watering Methods
Water thoroughly each time, but do not let the roots remain in standing water for a long time. In summer, with high temperatures, it is necessary to maintain moderate humidity. In winter, with low temperatures, watering should be reduced.
IV. Fertilizer Application
Cacti grow slowly, so fertilizer application should also be appropriate. Usually, apply organic fertilizer every 2-3 months, and you can also fertilize according to the fertilizer instructions.
V. Light Precautions
Cacti like well-lit environments but cannot tolerate direct sunlight. It is recommended to have 3-4 hours of sunlight per day, and also pay attention to avoiding prolonged exposure to strong light, especially in summer.
VI. Temperature Control
The optimal temperature for cactus growth is between 20-30°C, and it should not be lower than 5°C. It should be noted that in winter, cacti should not be exposed to cold winds, as this can easily cause the withering of branches and leaves.
VII. Pruning Techniques
The branches of cacti grow very slowly, but improper pruning can seriously affect their aesthetic appeal. It is recommended to prune in spring, keeping only the main trunk and a few branches.
VIII. Pest and Disease Control
Cacti have relatively few pests and diseases, but attention is still needed. For example, cactus snails and anthracnose are common pests and diseases. You can add appropriate amounts of sulfur and other drugs to the fertilizer to prevent them.
IX. Repotting Time
The best time to repot a cactus is in spring or autumn, as the temperature is more suitable then and can promote root growth. Avoid repotting in summer or winter.
X. Propagation Methods
Cacti can be propagated by cuttings, division, or leaf cuttings. Among them, the leaf cutting method is the most commonly used. Take a leaf and place it in a cool place; new shoots will grow in about 2-3 weeks.
XI. Precautions for Dense Cultivation
Cacti are not suitable for dense cultivation, as it can easily lead to insufficient air and light. It is recommended to plant one cactus every 15-20 cm to ensure their good growth.
XII. Preventing Leaf Spot Disease
Leaf spot disease is a common disease for cacti, mainly caused by hot and humid environments. In summer, it is important to strengthen ventilation and maintain indoor air circulation.
XIII. Precautions During the Flowering Period
The flowering period of cacti is short, usually only 1-2 weeks. It is important to promptly remove withered flowers and branches after the flowering period to avoid affecting the aesthetic appeal.
XIV. Environmental Adjustment
Cacti can adapt to certain environmental changes, but they should not be moved or have their growing environment changed frequently. During the growth process, indoor temperature, humidity and other factors should be adjusted.
XV.
Although cacti are easy to grow, some cultivation techniques and precautions still need to be noted. Choosing suitable soil, pots, watering methods, and fertilizer application can ensure the healthy growth of cacti. At the same time, avoiding pest and disease infestations and paying attention to factors such as light and temperature are also key to successfully growing cacti.
