What type of soil is best for growing cacti
This article provides information on the best soil for growing cacti and the optimal soil mixture for cacti, answering netizens' questions about cacti cultivation. Below, the editor will introduce the topic to everyone.
Cacti grow in deserts and have high drought resistance, so the soil must have good drainage. Poor soil mixture can easily lead to slow root growth or even root rot. Soil that is too sticky or compact is not conducive to plant growth; instead, choose loose, fertile, and well-draining soil to promote the healthy spread and growth of cacti roots. In addition to soil, the right temperature and ample water are necessary to promote vigorous plant growth. Let's discuss this in detail below.
1. Soil Mixture
Cacti prefer loose, fertile, and well-draining soil. You can use a mixture of decomposed leaf soil, garden soil, and perlite in a ratio of 5:3:2, and place gravel at the bottom of the pot when planting to increase drainage. Alternatively, you can mix peat soil, garden soil, fine sand, and vermiculite in a ratio of 4:4:1:1. Another option is to use sandy soil, which can be made by mixing garden soil, decomposed leaf soil, and coarse sand in a ratio of 6:2:2.
2. Choosing a Pot
Besides soil, the choice of a breathable pot is also important for growing cacti. Terra cotta pots are most suitable as they have good ventilation and drainage. You can drill extra holes in the bottom of the pot with an electric drill to facilitate drainage. When planting, you can place tiles or ceramsite at the bottom of the pot, or choose to lay a layer of pebbles to prevent waterlogging.
3. Temperature
To ensure robust growth of cacti, the temperature of the growing environment should be maintained between 20°C and 35°C. When the temperature drops below 20°C, the plant's growth rate slows down, and if the temperature falls below 0°C in winter, the plant may freeze to death and needs to be moved indoors for care. In the hot summer, measures should be taken to cool the plant and provide shade.
4. Watering
Watering is crucial for the healthy growth of cacti. Cacti are drought-resistant and prone to waterlogging; excessive watering can cause root rot and lead to the withering of the plant. Water when the soil is dry and ensure thorough watering. In the hot summer, when the plant enters a semi-dormant state with slow growth, watering should be reduced. In winter, when the temperature is cold, water should also be controlled, and watering can be stopped for a short period. In spring and autumn, when the temperature is suitable for cacti growth, watering can be done every 3-5 days. Avoid watering on rainy days to prevent the soil from becoming too moist, which can cause root rot.
The above information about the best soil for growing cacti and the optimal soil mixture for cacti can serve as a reference for cacti enthusiasts.
