• The best time to change the pot is in the spring months. When these months come, the existing pot should be replaced with one size larger.
• During repotting, you can follow these steps in order: The plant is carefully removed, its roots are trimmed, added to its soil, and replanted in the pot.

Soil

Irrigation

• Japanese rose flower requires plenty of water in summer.
