My summer fruiting raspberries have started to show signs of yellowing from the edges of the leaves, it looks like it may be deficient in something though I've fed it and kept it well watered.
I fear it may be a virus, but would like to ask if anybody can help to identify it and suggest a solution to treat it,
I feel it may be due to a nutrient deficiency. Raspberries like a rich soil.
Yes, looks like nutrient deficiency, or chlorosis. It's often worse on alkaline soils and during dry weather.
Give your raspberries a generous liquid feed with a balanced fertiliser, and repeat until leaves green-up again. Keep well watered when soil is dry too.
That's great, thankyou for the advice.
My raspberry leaves look like this too. I'm going to try to acidify soil with side dress of peat moss as I've read, too alkaline a soil can interfere with plant's ability to uptake iron. Makes this kind of leaves, yellow with green veins. So far my balanced organic liquid feed has not helped mine so I thought maybe they simply are unable to absorb nutrients well enough. NOW, "fingers crossed" for the peat moss.... !
