Rose likes soft and fertile soil. It is recommended to use sandy soil with good drainage performance. If the use of impermeable clay, root absorption of nutrients is insufficient, easy to lead to poor growth, flowering effect is not ideal.
If it's potted culture, change the soil every other year. If the root system grows more developed, change it into a larger flowerpot, trim the surrounding root at the bottom of the pot, and accumulate nutrients for flowering.
Rose is not resistant to waterlogging, but it likes water. When the topsoil is dry, it should be watered to fully soak the basin soil. Be sure to avoid standing water. Standing water for a long time will cause rotten roots.
Roses are not very strict in fertilizer requirements, especially when the soil nutrients are enough. If the nutrient is insufficient, you can choose the compound fertilizer which is rich in N, P and K. generally, it will be sold on the market. The amount of top dressing should not be too much, just thin fertilizer.
Fertilization method: turn the soil about 10 cm deep, apply fertilizer, and then cultivate the soil.
The growth of rose needs sunshine. It's very important to ensure sufficient sunlight. It's better to have more than 4 hours of direct sunlight every day. If you put it in an airless place for a long time, it will cause yellow leaves and other problems. In winter, the outdoor temperature is too low, so we need to move it to the window position for maintenance.
The growth of rose needs warm temperature, 12 to 28 degrees is better, and the lowest temperature can not be lower than - 5 degrees. We can increase the temperature difference between day and night to improve the ornamental degree of plants.
