(1) Avoid allowing it to grow. Roses have a lifespan of more than 20 years and have strong root sprouting ability. Old branches will weaken after 4 to 5 years and should be renewed and rejuvenated by division. In winter, dig out the old roots, divide the overly dense bushes, remove diseased and insect-infested branches, old branches and roots before replanting, apply enough base fertilizer and water thoroughly.

(2) Avoid placing it indoors for a long time. Too many potted flower branches and too strong rose fragrance will cause people's nerves to be overly excited. Smelling them for a long time is not good for the body.

(3) Avoid water accumulation in the pot soil. There should be no accumulation of water in the pot soil, otherwise the leaves will turn yellow and fall off.
