A small knowledge of life, about taking a small action on roses in winter, let's follow the editor to see the content related to green plants and flowers!
Mentioning roses, many rose enthusiasts' first reaction is beauty, followed by many diseases and pests. Indeed, roses are famous for being "medicinal jars," especially when cultivated in poor ventilation environments, where diseases and pests are particularly common.
Therefore, many rose enthusiasts ask in the store: What variety of roses is resistant to diseases, and does not get sick?
In fact, the popular rose varieties on the market now have pretty good disease resistance, but it needs to be clarified that good disease resistance does not mean no disease!
Many rose enthusiasts may doubt the relationship between rose disease resistance and illness. I was told that this variety is disease-resistant when I bought it, but why did it still develop black spots?

Let's make an analogy. The disease resistance of roses is like our human immune system. A strong and healthy person with good immunity gets sick less often. But does a person with good immunity never get sick their whole life? Of course not, it's just that they get sick less frequently compared to those with poor health.
The disease resistance of roses is the same as our human immune system. Good disease resistance only means that the probability of getting sick is smaller compared to other rose varieties.
In the same cultivation environment, if a rose with poor disease resistance gets black spot disease once a week, a rose with good disease resistance may be able to hold off for a month before developing black spot disease. This is the difference between good and poor disease resistance. Never think that good disease resistance means no illness.
In addition to the rose's own disease resistance affecting the frequency of diseases and pests, our management also has a significant impact on the occurrence of rose diseases and pests. Many times, we can reduce the occurrence of rose diseases and pests through more detailed management.
