What is the cause of this blueberry leaf condition?
- insufficient irrigation, because the system for watering the drop by drop is not yet in function and therefore the impossibility of fertilizing through the irrigation system.Blueberries were planted in December 2018 in sandy soils with a small percentage of clay.
- Otherwise, on the upper part of the plantation where these plants are often found in the wind. Fertilizer was used amosulfan and amino acids in combination with pesticides foliar over leaf.
Best regards and in advance thank you for your reply. Nikola
Thank you for your question, Nikola. I believe your county Extension office knows more about local issues, but you did not indicate your county, nor the variety of blueberry. Here is an article with information, but contact your county Extension office: https://catalog.extension.oregonstate.edu/ec1304 Good luck!
