3. Growth habits of roses

1. Soil: Roses are not particularly demanding on climate and soil during their growth period, but if they can be cultivated in loose, breathable, organic-rich and slightly acidic soil, they will grow more vigorously, grow stronger and bloom better.

2. Light: Rose is a very light-loving plant. It can only grow vigorously and bloom on schedule in an environment with sufficient light. Therefore, whether it is planted in the ground or in potted plants, the need for light must be met.

3. Temperature: Roses do not have high requirements for temperature, but it is best if the temperature can be provided between 15-26℃, so they can grow better. When the temperature drops below 5℃ in winter, it will stop growing and enter a dormant stage, but some varieties can withstand temperatures as low as minus 15℃.
