How to combat mold on orchids properly
Spreading on the aerial roots and in the substrate of a white surface, an orchid is affected by mold. If the pathogens are not stopped now, the floral existence is at stake. Read here how to effectively combat mold with simple measures.
Repotting moldy orchids - That's how it works
Mold on orchids can not be controlled by simply cutting off the affected aerial roots and sorting out infected pieces of substrate. The pathogens are invisible to the human eye for a long time before they show up as a floury-gray coating. We recommend quarantining the affected plant at the first sign and repotting it promptly. In these steps, you proceed professionally:
Put the stuffed orchid in the fresh pine bark with a twisting motion. Then you gradually replenish additional substrate, from time to time poking the pot on the table for a gapless distribution. Since the mold could form due to excessive humidity, do not water or dip the plant during the first few days. Only daily spraying with lime-free water provides roots and leaves with the necessary moisture.
Tips for the prevention of mold
Mold spores feel good wherever a continuous moisture dominates. Nevertheless, orchids demand a high level of humidity, so a good dose of intuition is needed in this regard. They deprive mold of livelihoods if you take the following aspects into account:
The desired humidity of more than 50 percent is provided by simple humidifiers, which are offered at low cost in the trade. In winter place on each active radiator a bowl filled with water. In addition, a rippling room fountain or an aquarium in the room are helpful. An existing coaster you simply fill with expanded clay and water.
Tips
If the leaves of an orchid are covered with a floury-gray patina, it is most likely not mold, but the mildew fungus infection. Do not cut off the diseased leaves in the early stages. Instead, you fight the disease with a mix of lime-free water and fresh milk in the ratio 9: 3. The solution is sprayed on the top and bottom every 2 days until the topping disappears.
