How to care for an air-pruned cactus? How often should the water be changed?
You may not know the small gardening knowledge about how to care for an air-pruned cactus and how often the water should be changed. Next, the editor will introduce it.
An air-pruned cactus is a novel method of care, which is cleaner and more hygienic compared to traditional soil cultivation, and also has higher ornamental value. However, the care methods for air-pruned cacti are different from those for soil cultivation, requiring special attention to some care points.
Firstly, the choice of container for air-pruned cacti is very important. You should choose a transparent and non-breakable container, such as a glass or plastic bottle. The size of the container should match the size of the cactus to ensure that it can be stably placed in the container.
Secondly, the water quality requirement for air-pruned cacti is high. It's best to use distilled water or filtered water, avoiding tap water, as the chlorine and minerals in tap water may be harmful to the growth of the cactus. Before adding water, you can let the water sit for a while to allow the chlorine to evaporate.
When caring for an air-pruned cactus, there's no need to submerge the entire root system in water. Only the 1/3 to 1/2 part of the roots needs to be submerged in water. This can prevent the roots from rotting due to prolonged immersion in water.
Like soil cultivation, air-pruned cacti require ample sunlight. However, it should be avoided to expose them to strong direct sunlight to prevent sunburn. When caring for them indoors, place the cactus in a well-lit area, such as a south-facing windowsill.
The water change cycle for air-pruned cacti is usually every 1-2 weeks. When changing the water, pour out all the water in the container and then rinse the container with clean water to remove any accumulated algae and bacteria. During the water change, you can also check the growth of the roots and promptly remove any rotting or diseased parts.
Since the nutrients in water are limited, air-pruned cacti have low nutritional needs. During the growing season, you can add a small amount of nutrient solution specifically designed for hydroponic plants to supplement the nutrients needed by the cactus. However, be careful not to overdo it to avoid fertilizer damage.
In addition, the care of air-pruned cacti also requires attention to the following points:
1. Avoid overcrowding: If multiple cacti are grown together in one container, ensure they have enough space to avoid squeezing each other.
2. Observe the growth condition: Regularly observe the growth of the cactus, such as the color and hardness of the leaves, to determine its health status.
3. Prevent diseases and pests: Although air-pruned cacti are less likely to be affected by diseases and pests, you still need to pay attention and address any issues promptly.
4. Trim appropriately: If the cactus grows too quickly, you can trim it to maintain its beauty.
With the above care methods, air-pruned cacti can grow healthily and become a beautiful landscape in the room.
