Need help ASAP with raspberry
Hi! My raspberry has begun to yellow and I can't quite figure out the cause. Spotted some aphids so I'll be treating with Neem oil, but I suspect there might also he some sort of nutrient deficiency. Hoping more experienced gardeners will be able to help me identify what its missing before I start throwing spaghetti at the wall!
Extra info: she's in a big pot, potting direct in soil is no go because I rent! Please ignore the rock it's not usually there. Located in the UK.
Thank you in advance 💕
