Red leaves on blueberries in Spring?
New to the forums and actually new to gardening in general. I recently got several blueberries (Northland and Toro varieties) and within a week or so, I noticed that some of them began showing red leaves. At the moment, we have them in containers.
I looked around and it seemed relatively normal in the Fall, but we are in Spring so it was kind of odd. Further research showed that it could be a variety of things from pH to nutrient deficiencies to even disease. In any case, here are two photos of them if it may help. Based on what I could gather, it may just be due to the weather or a phosphorus deficiency.
As you can see in one of the photo, the flowers on the Toros seems to have the most red on them. I am not sure if this is normal, but one of them (the Toro) has flowers falling off/shriveling off and fruit coming in.
We are in Bowling Green, KY (about an hour from Nashville). The weather has been odd lately. One week it was in the warm 70-80s, the next it would drop down to the 30s-40s. It has been 40-60s this week and finally got to 60-80s this weekend.
