Here I will disclose how to Save Rose Plant from Die Black Disease and black spot disease with expert tips on prevention, treatment, and proper care for healthier roses.
The Pattern of Black Spot Disease
Before moving on to the actual remedy for black spot Rose disease, you should understand the pattern of this black spot or brown spot Rose disease:
- They are Circular black spots or brown spots on the leaves.
- The lower leaves tend to be infected first, and then it spreads quickly to the whole plant.
- Then it causes leaf yellowing and the yellow leaves fall off.
- Subsequently, the plant gradually loses strength and either stops blooming or blooms less frequently.
The Preventive Measures to Control Black Spot Rose Disease:
So, the following steps are mainly the preventive measures to control black spot rose disease:
Location
Location is significant to prevent the development and spread of this fungus. So, carefully choose your rose garden location which receives at least 6 to 8 hours of direct sunlight. Preferably morning sunlight is best so that the nighttime dew dries out early. Enough air movement is also necessary around the plants.
Watering
Watering frequency and method should be appreciated. Especially watering early in the morning is the best way to prevent fungus so that the leaves dry out quickly. Instead of watering them in the evenings and letting them damp through the night.
Soil
Water should not stagnate around the plant at any cost. So, make sure you have a well-draining soil for your potted plant.
Soft Pruning or Removing Affected Leaves
If the black spot disease is not so extensive, soft pruning or remove only the affected leaves. Trim off all the affected leaves and branches keep them away and dispose of them safely. So that other plants should not get infected. It is better to use a trash bag and dispose of them.
Organic Solution Treatment
Neem oil spray is an example of an organic solution, which is the course of action I advise. 5ml neem oil in 1 liter of water weekly twice for 2 weeks and then a maintenance dose of at least monthly once or once in 15 days. If the conventional organic treatment fails, I think you can reserve Chemical Solution treatment.
Chemical Solution Treatment
It is well recommended to spray with broad-spectrum chemical fungicides like imidacloprid, and mancozeb which is a component of SAAF powder combination of Carbendazim 12% + Mancozeb 63%. For treating black spot rose disease, fungicides containing sulfur and copper are highly productive.
So, those are the treatments mentioned above that can save rose plants from Die Black Disease.
