Raspberries come in two types: summer fruiting and autumn fruiting. The main difference between the two, other than the time that they produce fruit, is that summer fruiting varieties produce fruit on last year's canes whereas autumn fruiting varieties produce fruit on the current season's growth. Raspberries are usually red but you can get white, yellow, orange, purple and black varieties.
Plant dormant canes in winter or early spring. They are suitable for areas with cool or cold winters. Prolonged summer temperatures above 30°C will cause raspberries to stop flowering. Raspberries spread very easily (sometimes too easily) so you are unlikely to need to propagate them. Summer fruiting raspberries fruit on two-year old canes so only prune canes that have produced fruit. Autumn fruiting raspberries fruit on one-year old canes so you can prune them after harvesting the berries. Some autumn fruiting varieties may produce two crops in a season so wait until winter to prune them.
Raspberries are ready to harvest when they are a deep red and are easily pulled off their inner cores. Typically fruit is produced from late spring to mid autumn. Different varieties produce fruit at different times.
They are particularly good in muffins combined with white chocolate. The leaves can also be used to make tea.
Raspberries are very high in manganese and are also a good source of fibre and vitamins C, K and E. They also contain antibacterial and antifungal phytochemicals (plant chemicals) as well as chemicals that prevent macular degeneration.
