What is the cause of the hollow root of orchids

The hollow root condition in orchids is likely caused by insufficient watering. If the growing medium for orchids is not moist enough and lacks water for a long time, it can lead to hollow roots. Also, if the growing medium does not make good contact with the orchid roots and lacks nutrients, it can cause hollow roots. After hollow roots appear, trim the roots promptly, replace with suitable growing medium, and ensure proper watering frequency. To prevent hollow roots in orchids: provide adequate light, good ventilation, more seedlings, or use coarse growing medium, and increase watering frequency accordingly.

Orchids are a common type of flower in our lives, and many people now cultivate them. Some may notice hollow roots in orchids, why is that? What are the solutions? The following is a detailed introduction to the causes of the constant root rot and hollow roots in orchids.

Insufficient watering

Causes: Orchids have different growth rates in different seasons, and their water requirements vary accordingly. For example, in winter, when temperatures are low and water evaporation is high, watering should be reduced. In spring and summer, when temperatures are high, water evaporation is high, and orchids grow vigorously, watering should be increased.

Solutions: When hollow roots are found in orchids, trim them promptly when repotting. If hollow roots are detected, consider first whether the watering amount is sufficient. Understand when orchids need more or less water. Only by understanding their growth patterns and adjusting watering frequency based on water needs can effectively prevent hollow roots and yellow leaves.

Watering not thorough

Causes: When watering orchids, it is recommended to use a slow, gentle stream of water. Do not pour a large amount of water directly as you would with other plants. Just seeing water coming out of the bottom of the pot is enough. Since the growing medium for orchids requires good looseness and breathability, stopping when water comes out of the bottom may not have thoroughly watered the plant, causing the lower roots to dry out and become hollow over time.

Solutions: Water orchids gently and let the water seep slowly. If the growing medium has not been changed for a long time and shows symptoms of compaction or poor breathability, pause for five to ten minutes after watering and then water again to ensure thorough watering.

Unevenly mixed or too large growing medium particles

Causes: The particles of the growing medium for orchids should not be too large. Large particles may ensure good water and air permeability but can make it difficult for the roots to fit closely, leaving the roots架空 and unable to absorb enough moisture, leading to drying and hollowing. It's like being tied to a place with a lot of food around but unable to reach it, which would lead to starvation quickly.

Solutions: The growing medium for orchids should be considered comprehensively, ensuring both looseness and breathability and a close fit with the roots. Large particles can cause hollow roots, while too small particles can cause root rot. Therefore, configuring the growing medium is a highly technical task. If large particles in the growing medium cause hollow roots in orchids, the medium should be replaced promptly, or the damage to the roots will grow, threatening the life of the entire plant.
