If there's one thing orchids can't stand, it's waterlogging. In order to specifically prevent this common problem, it is recommended to keep the attractive plants hydroponically with expanded clay. You can find practical tips in our article.
Can you keep orchids in expanded clay?
You can keep orchids in expanded clay. To counteract waterlogging, this is a recommended alternative to orchid soil. However, there are a few aspects to consider so that the orchids feel comfortable in hydroponics with expanded clay.
Why is hydroponics with expanded clay useful for orchids?
By keeping orchids hydroponically, i.e. substrate-free, you reduce the risk of waterlogging and root rot. Expanded clay forms a good base in the orchid pot. It iswater-permeable and particularly structurally stable In order for the orchids to accept hydroponics in expanded clay as hoped, the right approach and care are of course important.
How do I prepare the expanded clay for the orchids?
Before you put orchids in expanded clay, you shouldrinse the clay balls often until the water no longer turns brown. Then soak the expanded clay for 24 hours. Dry clay balls would remove the elemental moisture from the orchid roots. This must be avoided.
Note: Useonly intact beads, as broken specimens could damage the delicate aerial roots of the orchid.
What should you consider when caring for orchids in expanded clay?
It is important to fertilize orchids in expanded clayevery 2 to 3 months You also have to be careful with watering, especially at the beginning of hydroponics in expanded clay. Do not submerge the orchids. Initially only fill in water to a depth of around 2 to 3 cm. The capillary action of the expanded clay causes the moisture to rise upwards so that the roots are nourished. Over time, orchids develop water roots.
By the way: The expanded clay layer should be about 3 cm high.

Alternative: Cultivate orchids in orchid soil
Instead of hydroponics, plant cultivation in orchid soil can also be considered for orchids. This special soil is similar to the substrate in the rainforest, the original home of orchids.
