The buried portion of the stem should be scraped lightly to encourage root growth. The area where the stem is buried should be covered with soil and kept moist. After several weeks, roots will begin to form on the buried portion of the stem. Once the new plant is established, it can be separated from the mother plant and transplanted into a new location.
In conclusion, propagation of Ipomoea grantii Oliv. can be achieved through various methods, including seed propagation, cuttings propagation, and layering propagation. All the methods mentioned are relatively easy and can be done by anyone with basic gardening skills.
