How to solve the problem of continuously falling leaves on roses
Some rose enthusiasts have reported that their roses are not rotting at the roots, the plants are not withering, but the leaves keep falling, eventually turning into a bare stem. What could be the reason for this situation?
Actually, this is not due to our usual improper maintenance, excessive watering, or over-fertilization, but because your roses have been infected with a disease, specifically a fungal disease. This can lead to various diseases such as black spot, powdery mildew, and brown spot on roses.
Then, the leaves will fall in large numbers until they turn into a bare stem. If we notice a lot of spots and withered branches on the rose leaves, we can take timely action to effectively prevent the occurrence of a bare stem.
1. Pruning
First, prune all the withered branches and diseased leaves on your roses, and make sure to remove the lesions promptly.
2. Medication
Then, we use this benzoylpyrazole. This benzoylpyrazole contains both benzoyl propiconazole and pyraclostrobin. It has two fungicidal components with strong systemic and penetrative abilities, specifically targeting leaf diseases.
So, we just need to take out one small capsule, dilute it with about 500 milliliters of water, and spray the roses once every seven days. Continuous spraying for 2-3 times can effectively control the situation. When spraying, make sure to cover both sides of the leaves and the surface of the potting soil to effectively kill these fungi.
At this time, using some protective fungicides like carbendazim is advisable because their fungicidal effects are not strong, and they can only be used for routine prevention. Once the disease is actually present, we have to use fungicides with strong fungicidal and penetrative abilities.
This article shares specific introductions on how to solve the problem of continuously falling leaves on roses, hoping to bring some flower knowledge to flower enthusiasts.
