Iris Planting Service, 5 bulbs

Preventing Cold by Burying Soil: The full burial method involves covering the soil to prevent cold without the need for digging trenches on the ground. The thickness of the soil cover should be determined based on the local absolute minimum temperature and the cold resistance of the plant variety. In general, when the winter temperature drops to -15 °C, the soil covering should be around 20 cm, and when it reaches -17 °C, the covering should be increased to 25 cm. As the temperature decreases, the soil covering should be made thicker accordingly. However, for varieties like Kyoho and white banana which are more cold-resistant, a slightly thinner covering soil may be sufficient.
