Autumn raspberries

[roger]

I have some autumn raspberries which are growing well but the leaves are going light green to yellow. They are not dying (yet). Is this a lack of a particular nutrient (magnesium) or nitrogen? or a virus? Any comments

Hi Roger,

There is a specific ailment that raspberries suffer called "Verticillium Wilt" if they are planted in and around soil that has been used by tomatoes, peppers, potatoes etc in recent years as they carry a soil bound fungus. The symptoms you describe sound similar...
