When you do this, the leaves will start to turn yellow, which means the plant is entering a state of dormancy. This happens once a year, usually in winter. The dormancy phase gives the plant time to rest and recoup its energy for next season. Place the bulb on a wire cooling rack to provide airflow all around it. Leave the bulb out to dry for at least 12 hours, and up to 48. You want the bulb to be completely dry before you put it into storage for the winter.

How would you rephrase that briefly using Indonesian?
Hentikan penyiraman dan pemupukan setelah bunga layu. Keringkan umbi selama semalam.
