Often, the first thing you ask yourself when seeing black spots on your orchids is, “What are the black spots on my orchids?” Orchids are a beautiful plant, but they are also susceptible to fungal and bacterial diseases. Knowing how to identify these conditions can save your plant.
The first thing to do when determining what the black spots are on your orchids is to determine the root cause. A bacterial infection, known as Acidovorax, can be the culprit. You can easily prevent this infection by maintaining a clean environment and proper air circulation. You can also buy a bactericide from your local nursery, or online.
Moreover, you should avoid using water on your orchids, as it can make the infection worse. The best way to control the fungus is to apply a fungicide to the infected area. Once you’ve treated the fungus, your orchid will most likely return to good health.
There are two main kinds of fungus that cause black spots on your orchid. The first is Guignardia Leaf Spot, and the other is the Phyllosticta Leaf Spot. Each type of fungus has different symptoms, but they are all related to a fungal infection.
The Guignardia Leaf Spot is a smudge of brown or yellow, but can grow to be black. This condition is usually present in hotter climates. The Phyllosticta Leaf Spot is similar to the Bacterial Brown Spot, and can also turn into black sunken lesions.
If you notice black rot on your orchid, you need to remove the affected leaf immediately. You can use a sterilized knife to do this. This can prevent the rot from spreading. You can also soak the infected leaves in a solution of fungicide.
Why is My Orchid Crown Turning Brown
Having an orchid crown turning brown is not something to be taken lightly. If you don’t treat it early, it can result in a complete loss of your plant. However, there are ways to prevent and treat the condition.
Aside from the obvious, the first and most important step to prevent crown rot is to make sure you water your plant properly. It’s common for orchids to show signs of dehydration. For this reason, you should water your orchid at least once a week.
The proper air circulation is also essential to prevent the problem. You can provide air movement through fans or open windows.
You can also add calcium to the potting mix. This will help improve the vigor and strength of your plants. For example, you can use Cal-Mag, which contains magnesium and phosphorous. Check out my recommended products.
Another common ailment for orchids is root rot. If your orchid has a brown, mushy root, it means that the plant has become unable to absorb the water that it needs. If you catch the rot before it can get worse, it’s possible to save your orchid. During repotting, it’s also a good idea to remove any dead roots, of course.
In addition to the above tips, you can fix the issue by using a humidifier. You can also apply a 3% hydrogen peroxide to the base of your orchid’s crown. This is a relatively cheap and effective remedy.
Furthermore, you can try sprinkling cinnamon powder on the affected area. Cinnamon is known for its drying properties. It’s also used to treat fungal infections.
