Extended data:

The cultivation of roses is not strict with soil, medium alkaline or slightly alkaline soil is the most suitable, and slightly acidic soil can also be used. Therefore, roses should be planted in fields with sunny ventilation and good irrigation and drainage conditions, and in fertile loam on the edge of the land.

Roses should avoid low-lying and waterlogged areas. When waterlogging occurs, the lower leaves turn yellow and fall off, and even the whole plant dies. The flower bud and germination of roses need an average temperature above 7 degrees, and the effective accumulated temperature from the initial stage of germination to the flowering stage needs 365 degrees, which generally depends on the temperature.

Dry hot wind and soil drought are the most taboo in the rose period. For fields with water conservancy conditions, irrigation can be carried out in the bud period. In the process of production development, the growth period of roses stopped twice, at this time, the branches did not grow and the branches did not elongate.
