Many floriculture references describe open-ground roses as: fond of warmth, with a blooming period from May to October, but this is actually inaccurate. After years of observation, the author found that the blooming period of roses is longer than this: it can last from May all the way to November, or even longer. It does not fear frost, and only after snow do the flowers and leaves gradually wither; if pruning is done a little later, it is even possible to enjoy roses in the snow. Roses like sun and fertilizer, but they are also tolerant of poor soil and drought, and their adaptation to temperature fluctuates over the course of a year.

Many floriculture references describe open-ground roses as: fond of warmth, with a blooming period from May to October, but this is actually inaccurate. After years of observation, the author found that the blooming period of roses is longer than this: it can last from May all the way to November, or even longer. It does not fear frost, and only after snow do the flowers and leaves gradually wither; if pruning is done a little later, it is even possible to enjoy roses in the snow.

Roses like sun and fertilizer, but they are also tolerant of poor soil and drought, and their adaptation to temperature fluctuates over the course of a year. Although roses like warmth, they cannot tolerate intense heat. In the blazing summer, although roses still keep luxuriant branches and leaves, they produce few flowers and small blooms, and there may even be a flowerless period. Therefore, it is not rigorous for some references to also call roses "monthly red" and "three-season flower." Of course, some artificial measures, such as proper pruning, increased application of nitrogen and potassium fertilizer, and spraying water and shading, can alleviate the above conditions, but the quality and quantity of blooming are still hard to bring up to the standard of spring blooming, and cannot show the distinctive character of roses.

In areas of North China with extensive management, from July to August, one can only see roses blooming with thin, weak small flowers or flowers without leaves. But by the end of September, as the cool autumn wind gradually rises, roses also regain their vitality. No matter how extensive the management, they can still produce many high-quality flower buds. By October, the blooms are large, and the scene is no inferior to May. After the end of October, the weather gradually turns cold, and the number of flower buds gradually decreases, but the flowers that do open are still very large and full.

It can thus be seen that roses are very strict in their temperature requirements for blooming. Too cold or too hot is unfavorable for their blooming. Only the warm, cool seasons of spring and autumn are the most suitable blooming seasons for roses.
