Kerry starts with ... My blueberry plant that I have had for 12 months and which has been growing very well this season has these red areas just appear on the new leaves. The leaves were a bit yellow so I added some Ammonium sulphate to the soil because it didn't seem to be acidic enough.see photo showing no redness taken three days ago. I also put on some iron chelate solution. Now the red spots have appeared suddenly today mainly on the new leaves. What do you think is the cause? Or is it the treatment?I have only just bought two new blueberries plants and planted them.

Pauline Staff of Daley's Nursery says... Hi Kerry, your photo clearly shows the chlorosis of the leaves caused by alkaline soil. Adding ammonium sulphate is a good idea but it can take some time to take affect. I actually can't see red spots in the photo, but these may be blueberry rust developing as it was under stress. I hope this is helpful | About the Author Pauline Staff of Daley's Nursery Kyogle 28th February 2019 3:51pm #UserID: 19813 Posts: 87 View All Pauline Staff of Daley's Nursery's Edible Fruit Trees |

David01 says... Hi Kerry, I don't see any red spots on leaves from the photo. However, if you do have then the problem could be rust/fungus disease caused by the pathogen. Please see the attached links below how to cure it.
