How do I plant kumara?

You need to plant Kumara with rooted shoots about 20 to 25 cm high planted in raised ridges about 30 cm apart in rows 1 meter apart. The shoots need to be facing up I have read that it is good to bend each kumara shoot into a U shape before planting it, so that the roots would be facing up towards the surface of the soil. Remember to plant in free draining loose soil. Fertilise before planting but no more when the plants are growing as it will encourage vine growth
