What to Do If Orchids Don't Grow New Roots or Seedlings
Today, we are introducing knowledge about what to do if orchids don't grow new roots or seedlings. Next, the editor will provide an introduction for everyone.
What to Do If Orchids Don't Grow New Roots or Seedlings
If orchids always fail to grow new roots and the small seedlings do not grow, it indicates a problem with the orchid's roots. We should promptly repot and thoroughly inspect the root condition of the potted orchid to identify the issues causing the "failure to grow new roots" and "stunted growth of seedlings," only then can we determine how to solve the problem. As the saying goes, "First, take care of the roots when growing orchids." When the roots of orchids are healthy, the leaves are vigorous, and the flowers are fragrant.
Some orchid enthusiasts have asked: What should we do if orchids always fail to grow new roots and the small seedlings do not grow?
If orchids always fail to grow new roots and the small seedlings do not grow, it indicates a problem with the orchid's roots.
We should promptly repot, thoroughly inspect the root condition of the potted orchid, identify where the "failure to grow new roots" and "stunted growth of seedlings" issues lie, and then determine how to solve them.
Some beginners in orchid cultivation, due to a lack of understanding of orchid habits, find it difficult to grow orchids well, either not growing new roots or the previously emerged seedlings not growing.
The reason for this is mostly root rot. As the saying goes, "First, take care of the roots when growing orchids." When the roots of orchids are healthy, the leaves are vigorous, and the flowers are fragrant. The main causes of root rot are as follows:
1) The Cultivation Material Lacks Water Filtering and Air Permeability
An important point is that orchid roots need to absorb oxygen for respiration from the gaps in the potting material. If the drainage in the pot is not smooth and the potting material retains too much water for an extended period, it can lead to waterlogging.
If the gaps in the potting material are filled with water molecules and lack oxygen, the orchid roots will be oxygen-deprived, their respiration will be hindered, leading to suffocation. Over time, the root function will gradually be lost.
At this point, if harmful bacteria invade and multiply, the roots will rot. Rotting roots will not grow new roots, and the seedlings will not grow without nutrients.
2) Poor Water Quality or Unsuitable pH Level
The water used to water orchids must be clean and free of pollution, with a pH value between 5.5 and 6.5.
If the pH is below 5, it is too acidic, which can limit the absorption of essential elements such as nitrogen, phosphorus, and potassium, causing the orchid seedlings to lack key nutrients, and the roots and leaves to exhibit stunted growth and僵苗.
Moreover, the acidic environment is conducive to the growth and reproduction of root rot and other soil-borne diseases, which can damage the roots, leading to root rot and death.
If the pH is above 8, it is too alkaline, which can hinder the absorption of trace elements needed for orchid growth. Without the nourishment of trace elements, the roots and leaf buds will gradually wither, and may even turn yellow and rot.
