Diseases of orchids

Sometimes to understand that, what exactly has become your orchid, it will be very difficult. Even professionals can not always find the cause of the disease. For your convenience, we collected all the orchid diseases by sections.

Diseases of leaves of orchids

Withering leaves or any deformation of them indicates that something is going on with the plant. It should be noted that not all diseases are amenabletreatment. So, the appearance of kinks on the leaves is not a disease, but only a consequence of a flower trauma. Perhaps it was dropped, and the leaves were damaged. Also, kinks can appear due to rare watering, too rapid cooling of the leaves after watering or excess nitrogen in the fertilizer. About an overabundance of fertilizers also says that the leaves are deformed, thicken, acquire a dark green hue. Only after this, cracks begin to appear on them. Stop feeding your plant with organic nitrogen fertilizer, and everything will be fine with him. But it is also recommended to wash the root system of the plant and transplant it. It is possible that your orchid will cease to grow, but such behavior for a plant that has received too much nitrogen is normal. In the future, we recommend not using organic fertilizers.

If the leaves of orchids appear unusual ring-shaped spots or any other spotting, your plant is likely to have a viralmosaic disease. More details about the manifestation and treatment of this dangerous viral disease you can learn from the article of the Land of Soviets "Diseases of indoor plants: viral diseases".

Numerous diseases of orchids caused by pathogenic bacteria can severely damage the leaves. For the presence of bacterial disease may indicate: black spots with a bright rim near a healthy tissue (bacterial spotting), decay of leaves (bacterial decay). Details on how to deal with these diseases, you can learn from the article "Diseases of plants caused by bacteria."

Fungal diseases of orchids occur most often. Worse still, some fungal diseases can sometimes not be distinguished from bacterial diseases. The presence of a fungal disease can indicate such signs: orchid leaves turn yellow, smalldry black patches, large white, brown or black spots resembling a burn, rotting of the base of leaves (late blight), their tips or middle part, the appearance of watery spots with a gray bloom (gray mold), blackening of the base of leaves (fusariosis), red spots (rust ). A detailed description of the most common fungal diseases and ways to treat them you can find in the article "Diseases of indoor plants: fungal diseases."

Diseases of the roots of orchids

Due to damage to the root system or its overheating, the leaves of the orchid may fade. If your plant overheats, it shouldremove into the room for 2-3 hours and let it cool. Spray the plant immediately does not follow. Damage to the roots is caused most often by improper care for the orchid: overmoistening of the substrate, too much compaction, use of concentrated fertilizer or insufficient watering.

Soil fungi, which can develop in the old substrate, also cause diseases of orchids. In this case, the fungi prevent the ingress ofoxygen, moisture and nutrients to the roots. A characteristic feature of the development of fungi will be the presence of mycelium and the "mushroom" smell of the substrate. Also, the leaves of the plant can fade, shrivel and fall off. To get rid of this problem, the orchid will have to be transplanted into a new disinfected substrate and washed well by its roots.
