Dry Soil Conditions Increase the Risk for Winter Root Injury on Fruit Crops and Other Perennial Plants


The root systems of perennial plants are much less cold tolerant that the above ground portions of the plants. For the most species we can grow in Iowa, root injury can begin occur when the soil temperature drops below 18 to 15 degrees F. Fortunately, the soil has a tremendous buffering capacity and the temperature in the root zone seldom drops this low, but it can when there is a shortage of soil moisture going into the winter.
