I know Southern California isn't really the place where they would typically grow best but we have a couple of plants. Recently the leaves have begun to get reddish at the tips and then this spreads. Does anyone know if this means they are getting too much sunlight or not enough water or could there be some other issue? The fruit seems unaffected so far.

    Blueberry leaves tend to turn reddish naturally sometimes. I think it is a response to Sun. I would think that rabbiteye, or southern highbush blueberries such as tifblue would be better than northern highbush for southern california. They are not quite as sweet as the highbush, but they are very good.

    All blueberries are big time acid heads, do you know the soil ph there? That would turn the leaves red too i think.

    Here is a good conversation on red leaves in blueberries:

    I'm in the SF Bay Area. My blueberries just recently started turning red so I dumped a bunch of Cottonseed Meal around them and their green color is coming back. Cottonseed Meal is great for acidifying the soil along with fertilizing.
