Professional Iris Bulbs for Fall Planting-4 Bulbs-E

To prevent cold, one method is burying the soil at a depth of about 20 cm when the temperature drops to -15°C in winter. When the temperature reaches -17°C, increase the soil covering to 25 cm. This technique involves completely burying the soil without the need for digging trenches. The thickness of the covering soil should be determined by the local absolute minimum temperature and the variety's cold resistance. The colder the temperature, the thicker the soil covering should be. However, for cold-resistant varieties like Kyoho and white banana, the covering soil can be slightly less thick.
