Raspberries require well drained, deep soil. They do not tolerate heavy clay soils, or shallow soils, or prolonged water stress. They can tolerate heat in summer, but hot wind will devastate new growth and economic viability. The floricane fruiting (spring and summer) raspberries require adequate winter chill to fully and evenly break dormancy in spring. They are therefore unsuited to coastal areas of temperate Australia, or any subtropical regions. The primocane fruiting raspberries have a lower chill requirement and will crop in warm temperate regions. The cultivated blackberries will grow on a wide range of soils provided that drainage is adequate. Their winter chill requirements are lower than floricane fruiting raspberries. The late season thornless cultivars have a high water requirement for adequate growth and will not perform well on soils which dry out in late summer.
