Many soft fruit berries require a period of temperatures between for breaking dormancy. In general, strawberries require 200–300 hours, blueberries 650–850 hours, blackberries 700 hours, raspberries 800–1700 hours, currants and gooseberries 800–1500 hours, and cranberries 2000 hours. However, too low a temperature will kill the crops: blueberries do not tolerate temperatures below , raspberries, depending on variety, may tolerate as low as , and blackberries are injured below . Spring frosts are, however, much more damaging to berry crops than low winter temperatures. Sites with moderate slopes (3–5%), facing north or east, in the northern hemisphere, near large bodies of water, which regulate spring temperature, are considered ideal in preventing spring frost injury to the new leaves and flowers. All berry crops have shallow root systems. Many land-grant university extension offices suggest that strawberries should not be planted more than five years on the same site, due to the danger of black root rot (though many other illnesses go by the same name), which in the past has been controlled in major commercial production by annual methyl bromide fumigation but is largely prohibited now. Besides the number of years in production, soil compaction, the frequency of fumigation, and herbicide usages increase the appearance of black root rot in strawberries. Raspberries, blackberries, strawberries, and many other berries are susceptible to verticillium wilt. Blueberries and cranberries grow poorly if the clay or silt content of the soil is more than 20%, while most other berries tolerate a wide range of soil types. For most berry crops, the ideal soil is well drained sandy loam, with a pH of 6.2–6.8 and a moderate to high organic content; however, blueberries have an ideal pH of 4.2–4.8 and can be grown on muck soils, while blueberries and cranberries prefer poorer soils with lower cation exchange, lower calcium, and lower levels of phosphorus.
