We have some raspberry canes growing in a space in our yard and while doing some work this summer I removed some thorn bushes and stunted trees that were taking up sun, which was great for the raspberries since they flourished in the past two months. With the space we ended up putting some blueberry bushes since I had the space, and its fairly sunny, but now I am wondering if the raspberry bushes will be ok. Our soil is slightly acidic so I figure the raspberries can handle it, but if I am watering the blueberries will any acidic fertilizer I give them cause problems for the raspberries?
Yes, in short. These fruiting plants are not natural bedfellows: Raspberries prefer alkaline soil conditions, so the acidity required to grow blueberries successfully will not suit them. You could plant Blackberries instead of blueberries, they will thrive where raspberries do, and plant the blueberry elsewhere.
