Raspberries should be planted in the spring. Raspberries can also be planted in fall, but they will not produce fruits until the following spring. The ideal planting temperature is about 65 to 70 degrees Fahrenheit (18-21 Celsius). During warm weather, raspberry roots are more susceptible to disease than when temperatures drop below 55 degrees F (13 C). Raspberry plants grow very quickly and need plenty of space for fresh air circulation or else root diseases may occur.
