Strawberries are generally not exposed safely over the winter. Overwintering is an important measure for obtaining high yield in open field strawberries. Cover can be used wheat straw, straw, corn stalks, leaves, decomposed horse dung. The covering period is generally after the freezing water is poured and the soil is frozen. Cover about 5 cm in thickness. In early spring, when the average temperature is higher than 0°C, the cold-proof materials can be removed, and the surface can be cleaned, the soil can be preserved and the growth can be promoted. In areas where there is a late frost hazard in the spring, the cold-proof materials may be properly removed to prevent the plants from freezing.
