The winter hardiness of white clover is evaluated by the percentage of plant survival or the maintenance of sward density, as well as visually using a spring regrowth intensity scale. An important physiological indicator is the level of stored carbohydrates in the root necks before the onset of winter.
Low winter hardiness of varieties leads to thinning of the sward and weed infestation. The resistance of the crop depends on the management regime, including the timing of the last mowing, as well as the level of nutrient accumulation, which is influenced by phosphorus-potassium nutrition and weather conditions during the growing season.
