"The paper deals with temporal evolution of the last spring frost, first fall frost and the length of the frost-free period during the growing season of vegetable crops in Elbe River lowland (Polab\u00ED). A regular gridded network with a high horizontal resolution of 10 km was applied. The daily minimum air temperature from 116 grid points throughout the studied area for the period 1961-2011 was used. For each grid and for each year, the first and the last frost day in three degrees of intensity (mild: tmin 0.0 to -1.1 \u00B0C; moderate: tmin -1.2 to -2.2 \u00B0C and severe: tmin < -2.2 \u00B0C) were identified. Using these definitions, the last three spring and first three autumn frosts were specified for the spring and autumn of each year. The ending of the spring frost and beginning of the autumn frost were classified into three categories: early, mean, and late. In terms of the growth of field vegetables, a late spring frost remains as risk factor in Polab\u00ED, but the degree of risk has decreased. In the last two deca"@en .
