How to plant yams
The bulbils, pieces of tuber or small tubers are planted in the top of the mound at a depth of 5 to 10 centimetres, and covered with soil. When there is too much sun or the light is too strong, cover the mound with grass, so that the sun will not dry out the young plant and the rain will not wash away the soil and the tubers
- In savanna country where there is a long dry period, stakes are not used.
The aerial stems trail on the ground. By covering it, they prevent weeds growing, and protect it against dryness.
